“Time flies when your having fun” -light going from beginning of time to end of time in no time
"Tired light" is a wonderful example of formulating a hypothesis and then testing it by experiment or observation. In this case the hypothesis failed, but science still progressed.
I do not see much progress here. This failed hypothesis did not led to anything useful. If I propose that there is a small dwarf standing on every nucleon, would falsifying my hypothesis add anything to physics?
@arctic_haze falsifying the "tired photon" hypothesis provided plenty of new data sets that confirmed the "universe expands" hypothesis. What would falsifying your dwarf "hypothesis" contribute to?
@@JosePineda-cy6om This is nothing like the war has been won in the 1960s against the steady state hypothesis. Tired photons did not triggered much research, only some papers on time dilatation in quasars and surface brightness of the galaxies. So yes, technically that was progress but very local and limited one.
@@arctic_hazeThat is an outstanding example that I thought of decades ago, almost verbatim.
@@jjt1881 What exactly?
Tired light?
Last time I heard this theory I was in High School...1974!
Damn...that was really 50 years ago?
Light does not experience time since it travels at c.
I graduated '74.
@@douglaswilkinson5700 But light has momentum...light bends this way, that way...never in a straight line...gravity and all that.
Point being, accelerating a thingee takes energy, bending light is not 'free'.
@@pirobot668beta Light bends due to following spacetime curvature, not due to being accelerated.
@@pirobot668beta Well, I think the bending of light due to gravity is not so much force being applied, expending energy, rather, its space itself bending. So, to light's perspective, its traveling in a straight line.
It is possible that what we like to call the big bang is merely a local event in a much, much larger universe.
Yes!
It's also possible that this is a simulated hell, and that the only real people are the ones who suffer constant punishment.
Yes it is and I feel like a lot of astronomers talk about this being a real possibility however it’s incredibly hard to prove or disprove this
@@JB52520 This is hell? If so it's a pretty spectacular hell to live in if so.
No. If the big bang had been an explosion happening at a specific point in an already existing larger universe, we would get _totally_ different observations.
I love how the young earth creationist crowd was head over heels over the pop sci articles about the big bang being overturned but never bothered to check the source or stick around for the corrections.
This is irrelevant. This idea is about an older universe, which is the opposite of the creationists saying God created everything not too long ago.
Not trying to be a buzz kill, but the big bang theory is a creationist theory. It's straight out of genesis I.
@@Soupy_loopyLast Thursdayism is the simple explanation for that from a theistic perspective.
@@Soupy_loopy That's the whole point. Creationists always glom on to anything in science that is not understood and anything where the understanding changes based on evidence -- AS IF that boosts their case. It never does, but that doesn't stop them due to their exceedingly motivated reasoning. Have you ever heard them go on and on about the Cambrian Explosion? AS IF it proves that the earth was created in 6 days. If you tell them that it took tens of millions of years and ask which Cambrian fossil is their ancestor, they change the subject and soon enough go on about the Cambrian Explosion being evidence of a young earth again. They never correct themselves, they never bother to get the science right. And they did indeed do it again when this information from JWST came out about the universe looking older than we expect. Because they aren't about finding out what is true. They're about misrepresenting science to try to fit a mythology they've redefined as the capital T Truth.
@@MultiSpeedMetal Yeah I'd forgotten about Last Thursdayism. Oh I must mention there's no such thing as Last Thursdayism because as everyone knows, except you, it really is Last Tuesdayism.
New research, published in The Astrophysical Journal Letters, suggests a phenomenon called “bursty star formation” that can easily explain the puzzle of apparently high mass galaxies in the early universe. Instead of the steady rate and gradual star formation typically observed in more modern and massive galaxies like the Milky Way, bursty star formation features short, intense periods of stellar birth and death followed by longer, quieter phases. According to the simulations, this flash-bulb approach of bursty star formation can lead to some early galaxies emitting so much light that it inflates their implied mass. Using new simulations, Northwestern University-led team of astrophysicists now has discovered that these galaxies likely are not so massive after all and are young. The apparent anomalies have also been traced to erroneously using standard estimates (called IMF, or initial mass functions) for mass, relevant to the Milky Way in our current universe, to the early universe (See Becky).
Busty star lol that's funny. Try EU model is way more logically sound
tired light sounds less insane....
@@SanityTV_Last_Sane_Man_Alive The tired light concept has been debunked repeatedly since it was first proposed by Fritz Zwicky almost a century ago. Zwicky himself was sceptical about the concept. Tired light will produce dimmer and more blurry objects. However, astrophysical observations do not observe this. In other words, there is no evidence of this. The brightness and clarity of the objects is checked, as a matter of routine procedure by professional astronomers before the redshift is confirmed. Furthermore, the time dilation, as predicted by Einstein’s General Relativity Theory, is actually seen in the decay time of supernova light curves. This confirms that the cosmic redshift and light curves are independent of any hypothetical “tired light.” The CMB also does not support the tired light hypothesis as it would look different if this hypothesis was true. The perfect blackbody spectrum of the CMB, actually observed by our most accurate scientific instruments, contradicts the tired light hypothesis. The hypothesis is not able to explain such a spectrum.
Even in the darkest of times, Anton is still there covering all the fascinating science topics and calling us Wonderful Persons whilst being the Most Wonderful Person ;)
agreed ... its pretty much the only reason I remain subscribed
Dark times?
That Anton referred to someone who chose to attack another person's intellect using childish ad hominem attacks as "wonderful" is honestly not a good look. And what do you mean by "dark times" exactly? I'm not saying they are or aren't, I'm just curious as to what you're referring to, exactly.
@@AndyWitmyer its midnight here in the UK. thats what he means by dark times.
@Israelisnotourfriend it is ;)
dum kweshun - since the universe is expanding, shouldn't far away objects appear not only red-shifted, but also larger than they actually are? Because the light coming from them is passing through space that is not only getting stretched in the direction of travel, but also stretched side-to-side? So galaxies from the beginning of galaxy formation would appear magnified compared to how those same galaxies would appear if they were near by?
Yes, and that has been known for decades, and is taken into account.
@@bjornfeuerbacher5514 nice
Perhaps the blurriness should be an issue if it is distortion at larger distances, but one easily modify the hypothesis and say the blurriness will be seen at a bigger scale, just like they modify in string theory for undetected particles by saying they are heavier or require more energy and bigger colliders...
@@jonathanhockey9943No, the blurriness can't be modified that easily, it results from known physical processes.
And I think you confuse string theory with supersymmetry.

Because that's precisely what these people do - between false dates and critical alarmism, they push people away from a solution; why should you care about fighting against climate change if everything is doomed and there's nothing anyone could ever do?
The worst way to fight climate change is to be an alarmist
To my eye, the distant ring galaxy visible inside Hoag’s object actually does look a great deal less in-focus than the foreground galaxy.
As evidence against tired light, the claim of equivalent sharpness of image is not compelling.
That's due to the resolution of the picture
@@highviewbarbell
So what you're saying is the raw data was in better focus but the picture isn't?
Why would that be?
@@mmaximk are you asking me why a digital picture doesn't have infinite resolution and zoom?
@@highviewbarbell
Anton offered that image as a demonstration of a foreground object and background object being equivalently sharp.
As stated in my first comment, to my eye they do not look equivalently sharp.
Your first reply agrees with my premise that they are not equally sharp but your explanation for why that is the case is not clear.
My inquiry for clarification instead draws a defensive and nonsensical response.
Neither object is at an infinite distance.
The point was, as far away it is, it would not be visible, rather a blur. It is quite clear, maybe need readers?😂
After all you have been through, thank you for sticking with it and producing these wonderful and knowledgeable videos, Anton.
Thank you, Anton, once again for such amazing content ❤
I must’ve missed something, why do they expect tired light to burr? It has other problems, but where exactly does this blurr idea come from?
Yes, would be interesting to hear the supposed "Mechanism" involved here. As this claim is often made. But never seen the supporting explanation of how or why.
it wouldn't. its red shifted either way.
and I think anton needs glasses. those smudges were anything but clear anyway.
I’m actually on the fence between the two, but I doubt we’re anywhere near the proper evidence to legitimately estimate longer than we currently have just yet.
But thanks to various developments, last I checked, the presumed energy of space itself was approximated at 5 protons per cubic meter. In order for space to continue expanding without incurring certain hypotheticals like “cosmic rip” etc…
So even “inflation” itself may depend on certain elements brought up by the idea of “tired light”. So throwing out those notions completely may be part of why “crisis in cosmology” is even happening.
@@MarsStarcruiser Wow, this string is chalk full of the pontification of people pretending knowledge.
Very well, and nicely, done!
Thank you Anton for providing such an eloquent explanation of the subject material! You always provide objective observations backed up with science, facts, and logical reasoning - something that is missing online... May you stay blessed.
...did we watch the same video? normally i would agree, but this felt a lot more like it was personal for him. Something must have happened in his real life....
Thanks for clearing that uo Anton
This would be a pretty funny resolution to the Crisis in Cosmology, if _all_ of them turned out to be wrong.
That is almost certainly the caseb
You're wrong, Diphthong
We all know what the universe truly is
A crab. The one true constant in time and space.
Quiet heretic. How do you think science works? By open discussion of experimental data?
I thought it was turtles. All the way down!
Extra arguments:
1) Light travels at the speed of light, and therefore time slows down to zero from a photon's point of view; so a photon does not have enough time to get tired.
2) Energy has to go somewhere. If light loses energy, where does it go? We'd need some kind of "photon decay".
3) Constants could only change IF no net energy is riding on them. If changing a universal constant by a part per million would cause an energetic change in the universe equivalent to millions of supernovas, then it should require that sort of energy to affect the constant by that much.
Thank You again, Anton for yet another fantastic video! 👏
The thing that made me feel incensed was when I learned there is no scientific base for the multi-verse theory (the one where every decision splits into a identical universe, but where the other decision was taken). But so much media and even some scientists suggest it is more than likely true and there are numberless worlds just like our own existing and being made every second.
Yeah, you could say that they believe in the multiverse by… _blind faith._
There's a difference between science and belief. There always will be. You get to believe in anything you want to even if science says no way.
@@stephencorsaro954 Its one thing to believe in something, it's another to teach your belief as though it is scientific and to pass it off to the masses as fact
Thank you Anton,, for allowing me to reminisce!: Constants change (modulate) over time, haha, is something I pondered as a youngster. I came up with it on my own, and with a little math learning, and chemistry, I quickly admitted defeat with the gain in knowledge to keep me studying and thinking like the adult that I have become. It's been over 30 years now, and the thought brings a slight smile to myself when I think back on it,, kinda like santa. The same type of thought nags me of late when I consider MOND. It's really cute, and I understand how it gets blown out of proportion now that we can freely put these ideas out on the net. Gr8! Peace ☮💜
- Do red stars very far away appear more red due to the "red shift"?
- Gravity around a massive star or galaxy causes bending of space-time. It reminds me of the bending of light due to the refractive index of glass. Is the "red shift" just "the prism effect"?
Wonderful as always Anton. Thank you. 😉👍
You are a great science journalist! We appreciate your factual reporting and highly interesting topics! Keep it up:)
I saw this "older universe" story pop-up on my Facebook page. I knew it was B.S. as soon as I saw it. Thanks for the video! 😊
Great explanation, you make scientific theories much easier to understand.
Considering what we now know as a gravitational wave background, there can easily be an extra millimeter for every kilometer traveled due to gravitational effects on the photon, and that would add up and look a suspiciously lot like red shifting due to expansion, where the photon travels a non-perfectly linear path due to the photon riding up and down the gravitational waves as they pass through the same volume of space, such that the photon travels actually farther than a perfect line expectation measurement would give without the gravitational wave background. According to some physicists changing the timeline to 27.6B years ago for the Big Bang also gets rid of a lot of the Hubble Tension problems.
Don't believe in the Big Bang I believe it goes on forever and ever James Webb Telescope bring us perfect pictures love our universe .I expect to see chaos if there was a big bang out there. There's no chaos just beautiful galaxies.
I like the concept of grabbing new data, and redo the measurements every year using various methods, just to keep a continuous check of things. In a hundred years from now, any differentials would be visible in all these tested data.
The best comments from the scientific world recently is the admission of "we don't know. " 😮😂😂😂
something apparently Anton is ignorant of. Cuz we clearly dont know, but he made this whole video about how he knows.
Happens very rarely, sadly.
Thanks You for video! Great explanation!
Finally a good tired light hypothesis explanation, thank you!
Thanks!
Thank you for explaining this propperly because the amount of times i have come across videos and comments of people who don't know any better who say it's that old and all that... Was pulling my heartstrings, now i can sleep a lttle easier knowing fhe public is informed propperly by Anton the Legend.
Calm down, I'm pretty sure that most people never heard of this to begin with. I didn't, and I watch science channels all the time.
@@Soupy_loopy I ain't talking about you, shush.
As Einstein said, "I was wrong to suggest that there was no substrate that light waved in, and the assumption of a cosmological constant was my biggest mistake".
Seriously Anton. If you don't believe light gets redshifted over distance, you don't understand that magnetism affects charged particles.
If people only understood the constraints that cosmologists have to deal with when they build an extremely complex model, they might understand.
But I doubt it.
The speed of light in vacuum is c. But our universe has been around a while. Space isn't a vacuum, it's full of electrons and protons, metal ions, EM fields, dust, and 13 billion years of other detritus that builds up over time. Space has a refractive index that varies in unknown ways as light travels to us. Not to mention gravitational effects. It's not "tired", it's bent.
It is well known that light is "bent" a little bit on the way to us. This can be measured, this is taken into account.
Very nice, Anton! I am constantly trying to point out to people that work on "modified gravity" hypotheses is all very well as a thought experiment, but thinking that it will instantly override all existing observations that disagree with the concept is just plain ridiculous! Think I'll bookmark that article for sharing at them.
And modified gravity does not cause lensing!
From what I understand, we calculate the age of the universe based on the cosmic microwave background and the redshift of the light we receive from it. The older the image we observe, the denser the background appears. The older the images are, the more uniform they seem in every direction. This leads to the assumption that the universe is like a bubble, expanding more or less uniformly in every direction.
However, the cosmic microwave background isn't exactly uniform. It contains many darker spots (differences in temperature). As an engineer, I've had a wild idea for years: My hypothesis is that these temperature fluctuations are caused by dark energy, and I believe that dark energy could be the effect of gravity from other universes on ours. If this is possible, we might live in a 'cave' rather than a 'bubble.' Given this, we might be able to observe galaxies from other universes, which are much older than ours. It's a wild idea, but it helps me sleep. :P
Cool but dark energy isn't anything other than words used to explain away phenomenons.
It's the equivalent of saying "God" to explain things that you don't understand.
@@aliensarerealttsa6198 There's a difference between the two. Saying "God" is a way people might try to explain all sorts of things they don't understand. But "dark energy" is a specific term scientists use to talk about why the universe keeps stretching out faster and faster.
A gravitational interaction from extra dimensional objects or entire universes, could offer an explanation for the dark energy.
Do we really know how old the universe is. I believe it is much older than what we understand. Like other predictions that are just wrong that have to do with the universe. And I’m not a big bang theory guy. It would be impossible for a singularity to expand to what we see now. The physics that could explain this doesn’t exist.
"Do we really know how old the universe is."
Yes. That can be determined by different methods, and the results agree with each other.
"I believe it is much older than what we understand."
Your belief is based on ignorance. You simply don't know all of the observations.
"And I’m not a big bang theory guy."
What's your alternative?
"It would be impossible for a singularity to expand to what we see now. "
Why?
"The physics that could explain this doesn’t exist."
Yes, it does. It's called "General Relativity". Has existed for over 100 years. Ever heard of that?
Impossible to imagine what we don't know! We imagine ourselves as a highly advanced society until something very special comes to light. If our universe is as old as we previously thought, we're still scratching the surface of knowledge. Our history only goes back a few thousand years.
Impossible to imagine what we don't know?
Rubbish. That means we would never learn anything.
The opposite is true. We imagine things that we don't know. And also imagine things that are false.
Someone tried to call me a fool because i didn’t know the universe was actually 27bn years old but when i asked for a source, read that source and then critique the way the data was used and interpreted, i got no reply. So goofy
Photon packet disbursement in gravitational, electromagnetic localities slows light, but this affect is local. Hence tired light is only tired at localities, and cannot exist in non-localities.
The tired light theory makes more sense than assuming a Doppler effect supporting an expanding universe theory.
I was a radar operator in the US Navy in the late 1960's.
High frequency radars have a shorter effective range and were used in target acquisition systems.
Low frequency radars were used for long range identification.
High frequency electromagnetic emissions loose their energy more rapidly than low frequency radars.
Light is an electromagnetic wave in the human visual spectrum, lower frequencies of light are called infrared.
All of these electromagnetic emissions travel through vastness of the universe, they encounter charged particles, clouds of dust, and other electromagnetic waves from many sources. All of these encounters absorb energy from the full spectrum of emissions, the further the source, the more energy is lost.
It seems more reasonable to me, that the further away a light source is, the light will be red shifted by the distance and not the velocity or direction of the source. The Hubble Constant is still valid, assuming that all light sources emit a full spectrum of electromagnetic waves.
The "Big Bang" or expanding universe theory requires a starting point, a singularity, where nothing existed until it did,
Sounds more like a scientific creationist theory.
More will be learned in the future. There will be more versions of the James Web Telescope that will be stationed further out in our solar system. We will see much further, We may see billions of new galaxies. We may finally stare into infinity.
_"The tired light theory..."_
Does not exist. No mechanism, no evidence, and no need for it.
_"The "Big Bang" or expanding universe theory requires a starting point, a singularity, where nothing existed until it did,"_
Wrong. That just shows that you do not understand what the BBT actually says.
_"All of these encounters absorb energy from the full spectrum of emissions, the further the source, the more energy is lost."_
And would also cause blurring. Did you not watch the video?
@visualedtech The red shift is not explained in terms of a doppler effect, its not because the source of the light is moving away. The mathematical theory put it down to an expansion of the very fabric of space, the light is travelling through/in/on a medium that is expanding. The universe and its galaxies are not expanding into something, the universe itself (the fabric of space) is expanding. That's their current best model.
_"they encounter charged particles, clouds of dust, and other electromagnetic waves from many sources"_
All of which cause blurring of distant objects. Which is not seen. Fact is, tired light is considered crackpottery, because it is invoked by said crackpots without having a single viable mechanism.
_"The "Big Bang" or expanding universe theory requires a starting point, a singularity, where nothing existed until it did,"_
Nope. That is a flat earth or creationist level explanation for what the BBT says. Hint: it does not say that.
Does your high frequency emissions transform into low frequency emissions over time?
Photons might get "tired" and loose fractions of there energy when they interact with virtual particles.
This also makes some virtual particles convert to real matter conserving the constant of energy.
If you can make the equations to show that and demonstrate that this process would create more matter than antimatter... Dude, you could get a Nobel.
Seriously, because it would also explain why there's so much matter compared to antimatter.
Yes but any kind of scattering would make the distant sources look diffuse. Anton explains this in his video.
Changing constants over cosmological timescales is one of those areas I've wondered about. It's nice to learn about the evidence that refutes the idea.
Love this channel! This one made me laugh.
Photon man: "I just flew in from Betelgeuse and boy am I tired! Really, you wouldn't believe the traffic I had to squeeze through just to get here. Good old "Juicy" let one rip? ;)
Light cannot be tired. It does not experience time.
I thought you were going to say …” I just flew in, and boy are my arms tired! “
Yeah, I think the University of Ottawa proposal is pretty weak. Doing science, you've got to get as comfortable as possible with knowing that you don't know yet. Thanks Anton.
I'm certainly no physicist, but a while back I came up with the idea that parts of a wave function that get consumed by black holes cannot collapse backwards through the event horizon. Traveling particles would appear to lose energy the further they get from their source, specifically a decrease of distance traveled squared, and a smaller cubed component, based on the surface area and volume respectively, of the virtual relativistic sphere that the wave function could exist in. This would also let us map the evolution of the density of primordial black holes throughout the lifetime of the universe.
Idk how quantum physics would handle collapsing only part of a wave function and letting the other half persist, but I thought it was an interesting idea when I was in college lol (I understand wave functions more now haha)
It's fun to try to come up with novel solutions, it's just important to acknowledge them as highly speculative, and not cherry pick evidence that specifically backs up your idea 😊 Much love to all the scientists who are willing to self-criticize 💛
I like the idea of no beginning.
In our tiny microcosm, time is very very swift, maybe it's not possible to imagin such a thing.
a very passionate, fantastic video. a very outspoken vibe to it.
We are blind men stumbling around in the dark.
So much for the University of Ottawa astronomy program. Glad I went to other university.
Yo .. I think my guy sped up his talking speed in editing. I'm all here for it 🙏🙏 thank you
So, on the one hand, there would be an unknown mechanism that is stretching out the wavelength of individual photons, perhaps at the quantum scale, involving relatively small amounts of energy. On the other hand, we have an unknown mechanism that is expanding the entire universe, stretching out the wavelength of individual photons in the process, involving staggeringly incomprehensible amounts of energy on a cosmological scale. Hmm....
"involving relatively small amounts of energy. ... involving staggeringly incomprehensible amounts of energy on a cosmological scale"
??? What on Earth are you talking about? The amount of energy obviously is the same in both cases, since they result in the same observed redshift!
@@bjornfeuerbacher5514 Are you sure that you understand how cosmological redshift works? As the universe expands, that expansion stretches out the wavelength of the light passing through space. The "staggeringly incomprehensible amounts of energy" to which I refer in that instance is the energy required to expand space, not the energy required to stretch the light. A tremendous amount of energy would indeed be required to expand the universe; that is why physicists say dark energy would have to make up 68% of the energy in the observable universe.
It does not follow that stretching the wavelength of light by any other, currently unknown mechanism would require the same amount of energy as is required to expand space itself. For example, if virtual particles created transient spacetime curvatures that have an effect akin to gravitational redshift on passing light, the amount of energy involved would be, relatively speaking, much smaller than that required to expand the universe 😉
Though... in truth, virtual particles do not strike me as a likely candidate for an "unknown mechanism" responsible for observed redshift, since those transient spacetime curvatures should, in theory, cause light to blueshift as it entered them, then redshift as it exited them - with a net wavelength change of zero 🤣
@@bjornfeuerbacher5514 It's a fair observation. Either the universe is getting bigger, or stuff inside the universe is getting bigger. I'd say making the universe bigger would need a wee little more energy than stretching a few photons.
I took a flashlight into my bathroom and my toilet bowl bent the light. Massive dark matter helped
Could you make out your reflection?
Did you produce the dark matter in the toilet yourself?
Was Nibbler in there first?
jesus Bella, what did u eat to make all that dark matter? 😂
@@theskullyhippiedude3719 my first association,too.
I don't remember much of it but my favorite theory on the start is that there's something like a quantum field that some times vibrates and creates/disappears matter, when an area is voided enough some matter becomes stable and stays around. meaning the universe may have just slowly appeared over a large area at one time instead of in sudden bangs.
also a question. have we noticed more red shifted lights in one or two directions more than the other directions?
Thank yiu Wonderful Anton !
Thank you for this. I'd heard about this hypothesis but had no idea whether it was well founded or not. Your video so helpful.
Dark matter is dilated mass. In the 1939 journal "Annals of Mathematics" Einstein wrote -
"The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of G.R. predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". A graph illustrates its squared nature, dilation increases at an exponential rate the closer you get to the speed of light. A "time dilation" graph illustrates the same phenomenon, it's not just time that gets dilated.
Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. There is no singularity/black hole at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. In other words that mass is all around us. This is the explanation for galaxy rotation curves. The "missing mass" is dilated mass.
Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. This also explains why all planets and all binary stars have normal rotation rates, not 3 times normal.
The concept of singularities is preventing clarity in astronomy. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc.
@ConontheBinarian General Relativity predicts dilation, not singularities. Dilation is the elephant in the room explanation for galaxy rotation curves
Penrose demonstrated singularity to be inevitable. Not sure but I assume massive particles are destroyed before they have a chance to reach light speed anyway. Final issues being information loss due to Hawking radiation but that has also not been observed. Safe to say the event horizon at least has been observed, therefore, a possibility the singularity is behind it as implied.
@@RicardoMarlowFlamenco There is no singularities, Hawking radiation or event horizons. Black holes were popularized by television and movies beginning in the 1960's. What we see in modern astronomy has been known since 1925. This is when the existence of galaxies was confirmed. It was clear that there should be an astronomical quantity of light emanating from our own galactic center.
@@shawns0762 "General Relativity predicts dilation, not singularities. "
I already told you several times that GR predicts _both_. Why do you keep repeating this falsehood?
"Dilation is the elephant in the room explanation for galaxy rotation curves"
Show your math.
Light dissipates energy as it crosses the universe when it interacts with random matter. Inverse square law is the current best mapping of this phenomenon.
thank you,, did follow this closely.. liked and shared ofcourse..
Redshift is caused by an increase in wavelength, not a loss in velocity or energy.
Stay Wonderful, Anton!
It still loses energy though... E = (hc)/λ
The "loss in energy" was a reference to the "Tired light" hypothesis
@@AntonioDellElceUK Which actually sounds far more plausible than a universe expanding at the speed of light :D
If some of the photons were lost out of the signal, then distant galaxies would appear to dim rather than fade. The photons remaining would still be sharp and in focus. The waves of photons may redshift simply because less of them would cause some of them waves of photons to disappear entirely. Maybe there's a chance they just get grabbed up on their way past a random proton.
Conservation of energy does not hold in an expanding universe.
3:34 i mean it makes sense if light is considered a wave, it can't move forever and maybe could work with the Doppler effect, the only way we can find out is to get more data. (Not saying it's correct by any means but still we need data to figure out what is actually going on)
In the game of life, walkers will propagate forever unless they hit something. Not that the universe is like that. I'm just saying that it's possible for activity to propagate indefinitely in the right medium. Some waves can move forever.
"it makes sense if light is considered a wave, it can't move forever"
Huh? How does that follow?
@@bjornfeuerbacher5514 well the osculation of a wave is movement which changes direction so one would thing energy is used to do that unless light has a special thing going on or actually isn't a wave while traveling.
@@deltacx1059 osculation? Do you perhaps mean oscillation?
"is movement which changes direction so one would thing energy is used to do that"
Do you _really_ want to claim that as waves propagate, energy is consumed, or what?!? If yes, you should read up on basic physics.
6:44 - "Without providing any definitive proofs". Dark matter and dark energy have entered the chat
We know that both dark matter and dark energy exist, because we have detected them.
@@weltschmerzistofthaufig2440No they haven't they just see an effect but don't know the cause and simply say its dark matter lol
There's ways to try explaining those effects without dark matter, like electromagnetism and other wilder ideas
@@mexicanosquad6390Dark Matter is the observation that we cannot explain the motion of stars in a galaxy without there being substantially more mass than is radiating any light, so there must be some mass there that does not interact with light. We know nothing about the nature of such particles other than they should be there and not interact with light.
Dark Energy is energy of an as of yet unknown source affecting the expansion of spacetime.
If you really want to get down to it, they are labels of "Needs Further Investigation"
Personally, I think we will not have good answers for either until we have some proper and functional understanding of how to link quantum mechanics and relativity or get some sort of quantum gravity.
@@weltschmerzistofthaufig2440
Why do you open your mouth with ignorance? The terms are place holders. We have zero idea what it is. The only thing we know is our model doesnt take into account 90% of everything.
Ha! Maybe not…
The galaxies we see at extreme distance in the CMB seem blurry indeed!
i still remember watching the live report on the Higgs-Bosson particle from the VLC in Geneva, when it was called out it was a 'split decision' between our current 'periodic table model' and/or transferring towards a complete overhaul into our view of space-, and time, and how this decision was made based on absolutely nothing more than a nostalgia towards our current system and the loyalty shown towards those scientists that created the periodic table, rather than actual proof. that decision was such an eye-opener for me that my 'grain of salt' idea got only more footing about our origens and science as a whole.
It is so easy for all of this information to fly directly over everyone's head and become uninteresting, but Anton always seems to present the information in a way that is engaging and informative. Thank you for the amazing content as always!
I mean, we know light is affected by gravity. It's quite possible that the pull on light along with slingshoting around galaxies likely affects light velocity in many ways in addition to the matter dispersed in space. No part of our universe is ever truly empty.
As for the claim, it would blur images, I very much doubt that. No effect like this has ever been observed, telescopes don't work like eyes.
Ultimately I think using light is a bad idea for determining the age of the universe. The speed of light is only constant in a perfect vacuum.
Can't wait to read your peer-reviewed paper.
Mass curves spacetime. Light in a vacuum travels along this curvature.
The velocity of light is a constant to all observers.
Simple put, light changes speed as it interacts with a medium, Cherenkov radiation and such, moving through water, etc. a photon takes years to exit the Sun … however once uninhibited in vacuum it moves exactly at C.
"It's quite possible that the pull on light along with slingshoting around galaxies likely affects light velocity in many ways in addition to the matter dispersed in space."
Yes, this has been known for decades, this has been measured, this is taken into account by cosmologists.
"The speed of light is only constant in a perfect vacuum."
Space is so near to a perfect vacuum that there are only ___VERY___ small effects on light.
"Ultimately I think using light is a bad idea for determining the age of the universe."
So what else do you suggest?
And: Did you consider that we can also measure the ages of indivual stars, and these ages agree in essential all cases with the age of the universe determined in other ways?
I have to say, you are decent,rational,logical & beautiful minded .thank you🌷
Reminds me of a t-shirt I saw while browsing through an army surplus store in downtown Toronto over a decade ago. It had the Insignia of some army sniper Squad and contained the words: " you can run but you'll just die tired" 😅
Everyone, everything gets tired by expending energy. Bullets, people. Everything but not photons
Speaking of tired light, I remember listening to a scientist, Roger Penrose I think it was, who had a theory that the speed of light may not be constant, but may slow down over time. Not being a scientist myself I'm not sure if this would affect the red shift or not or how that slowing down would affect our perception of the age of the universe. Not even sure if it could be proven. Not sure how his theory worked but if I remember correctly it went something like the speed of light would slow down to a critical point and that would be the end of our universe, but the beginning of another big bang and the creation of another universe after ours. It was pretty interesting, but the theory was way out of my league for understanding how the nuts and bolts of the thing actually worked. .
Err, did you miss the part of the video where Anton was addressing exactly this? (a change in the constants of nature)
"who had a theory that the speed of light may not be constant, but may slow down over time." It is not implausible under the concepts of inflation. I would even go as far to suggest that this may be a fundamental aspect of time-space.
I am not an indentured physicist.
I am tired of hearing so often about tired light. Thanks Anton for debunking this.
"The matrix is older than you know. I prefer counting from the emergence of one integral anomaly to the emergence of the next, in which case this is the sixth version."
I’m tired of Big Bang cosmology when all but one of its predictions are falsified, yet ppl still parrot the same old bs.
If a big bang creates a universe and nobody is there to hear it, did it make a noise?
The trouble is, Anton didn't actually debunk tired light. What he did was show that if such a phenomenon exists it doesn't exist in the way, or to the extent it was presented, without other new physics
@tenbear5 what big bang predictions have been falsified that haven't been explained by inflation
VERY COOL 😎! Thanks Anton!
My son's taking astronomy . His teacher said he was taking up space in class. Such a good kid 😉
💔💔💔 my serious condolences for your son and the loss of such a beautiful person that I know he would have grown up to be because you are absolutely beautiful in time thank you for everything!
thx Anton, for your clear explanation why tired light hypothesis is probably wrong. Since there were no updates from scientists who endorsed the hypothesis I already thought it might be wrong. Thx for the background information.
Yes, it's good to never question anything.
Anton has mostly retold a website named "Errors in Tired Light Cosmology". Yes, there are several problems that tired light creates why solving none.
I wouldn't throw out tired light as a phenomena as it is after all one of the primary indicators used to determine that most of the strange signals the Earth get hit with aren't from aliens. It can help explain some galaxies but not others where some seemly have more mass than others but putting a date on that sort of thing is a misunderstanding on how light still needs to interact with something like space dust or whatever to get "tired". I don't know how the permeability aspect get skipped over in these studies particularly with the CMB.
"I wouldn't throw out tired light as a phenomena as it is after all one of the primary indicators used to determine that most of the strange signals the Earth get hit with aren't from aliens."
What on Earth are you tallking about?!? Where, how, by whom etc. is tired light used for that?!
Light doesn't get tired. It's just sick of always being the fastest. Sentient Light Hypothesis.
I have always felt we have alot to learn as it comes to the expected age of the universe. I can't wait to see what we discover
I am glad Anton focuses on physics papers and doesn't work for the government's taxation department. I usually take the log of my revenues. The gentleman, who wrote the papers, has some work ahead of him.
This was an excellent video.
Constants can be pretty constant sometimes.....lol
I think its incredible that we are still in the infancy of our understanding and that we continue to challenge theories as our abilities to test them out with technology grows as our knowledge increases. Its must be an exciting time to be a physicist, a scientist of all kinds.
Another wonderful video.
I'm sure people in a few centuries from now will watch many of our present day science videos while cringing or laughing at how wrong or simplistic our understanding was. Thats the thing about science, it's always tentative and is subject to be superseded by a better theory. I'm sure whole new fields of physics and even a paradigm shift about how we look at the universe is in our future.
Newton's laws of motion are still valid and in use today. Planetary orbits, rocket trajectories, etc. all use Newton's laws. It's only when dealing with relativistic problems are Einstein's Theories required.
Or maybe everything we know right now will get lost as society collapses worldwide
We don't know what will happen, we just like to assume things will get better under the illusion of eternal linear progress, which has turned to not be that eternal nor linear after all
If one is estimating the age based on light and telescopes, then one can never say with 100% precision. For that matter, I don't think science is enough to tackle this issue
Using redshift calculations and spectrometry has given us many accurate results. Also, why do you say that Science is not enough to tackle this issue? It is the only way to figure out a solution.

@@weltschmerzistofthaufig2440I think the OG comment was just trying to point out the truth. That no matter how much we try, we are limited to the perspective we've been dealt. There are limitations to what physics and the laws of nature will allow us to achieve, to measure, to observe. The rest is beyond our reach due to the limitations of the perspective we have. It doesn't mean you doubt science, it means you don't let ego get in the way of science. It's unrealistic to think will be able to discover all the answers related to our universe. No matter how far we advance, we will never be able to truly learn what happens when something gets sucked into a black hole? Also no matter how much we advance we will only be able to measure, observe so far around us in the universe UNLESS we (the observer) drastically moves but that would require such an immense distance to make even the smallest difference.. Even then, no matter how much we move there will always be aspects of the universe out of reach to observe due to the rate at which they are seeing the universe expand.. I think that's the kind of stuff the original comment was referring to.. I could be wrong tho..?
Here's a question Anton. How "old" is a particular black hole? If we think about it, lets say we could prove that a certain black hole formed 1 billion years ago. But that's one billion years from our time frame on earth, at 1g of time dilation. But a black hole is, from our perspective, living in slow motion. If there were a life form within the event horizon of that black hole, they might only "be" 100 years old, while watching a billion years go by on earth. The same concept applies to any matter at differing degrees as it depends on the time dilation of the space it resides in.
i’ve always wondered about this
I think there is an epistemological element to such considerations. Logically, time is a mere concept derived from the comparison of processes.
For me, there is only the present moment, which by force of circumstance means everything all at once. The implications in terms of relationship are huge, indeed unfathomable. In essence, the present moment is part of a dynamic, everything recreating itself from moment to moment. It follows that creation was not some event in the past, but that creation is and always has been in the present moment.
No, time is a fundamental aspect of the universe. It is the temporal dimension that marks the gradual increase of entropy in the universe, and is one of the fundamental units of measurement. Calling time a concept is like calling distance or speed concepts that don't exist in the real world.
@@weltschmerzistofthaufig2440Time isn't fundamental to the universe, but fundamental to our current understanding of it. All of these measures are derivatives based on comparison. They are part of a Newtonian world view and extremely useful for things such as engineering. However, within the Newtonian world view, the second law of thermodynamics is the most vexing, as from a human perspective (our current state of knowledge) it would seem be the only irreversible law in physics. Why is that?
@@weltschmerzistofthaufig2440 Time being fundamental to the universe is an interesting discussion. Also real and not real is an interesting discussion. Being able to define real and not real is a difficult task. I would be willing to declare time as being fundamental and real, but not physical in any spatial sense.
I’m 50. I feel like I’m 80. I can understand if the Universe feels older than it really is. It’s been through a lot. Those black holes really suck the life out of you.
Totally agree with the constant it's in real charge over time. And time is also not a constant, in the early stages of Univers. The graph looks like an inverted exponential curve. Starting from infinity.
I have a feeling a lot more light permeating the universe, takes a drastically longer path then we realise. Imagine the gravitational lensing effect, but vibrating into resonance patterns. Like sand on a speaker makes beautiful patterns, but in 3D.

I have been laughed at in lecture theatres for stating the Big Bang did not happen. You were not allowed to challenge it, even ridiculed by the much smarter man presenting, because they know best.
Maybe, because it did happen? Call it inflationary or something. But, we layman know it as the big bang because it works for us.
Bad style of the lecturer. But nevertheless, he was essentially right - claiming something like that without having ____VERY____ good evidence is indeed ridiculous.
