Cosmic distances are a lot bigger than they may seem, and light has to cross that path in order for us to see stars and everything. Here i explain what would our planet look like from Andromeda and how big would the mirror of the telescope need to be.
The idea for the video was given by Der Tery (through a comment).
Sizes of the telescopes calculated through the help of this article: www.askamathematician.com/2013...

So maybe we already found planets that host life... but we're looking at their past where life didn't exist yet. Could that be possible?
Yes that might be a possibility but even if we did find something it would need to be 3.5 billion light years away to possibly be intelligent since that's approximately the time that took single celled organisms to become multi-cellular ones like animals and humans
I remember hearing in another video like this that it's probable that life formed on another planet long before Earth existed.
So, maybe there could have been intelligent life out there enough years ago that their radio signals will reach us soon. Who knows?
It's also quite possible that by the time we get there (Say a star 40,000,000LY away) that civilization may have risen and fallen.
@@Dankolicious All possible, but we wouldn't know, unless we found technology on mars to boost our understanding of physics
One day we all will die no one will remain on thir universe... Only Allah almighty...... Mark my words no one can leave forever....... That day will come than u will remember........(Every leaving thing is born to die)......
So that would mean that out there somewhere, a “image” of the dinosaurs is travelling through space.
"an image"
@@FaasOnline yeah thats freaky to think of infact, the image is embedded in the light, thats how photography works, it takes a shot of the light, so if you could catch the light from back then you would have an image of the past. light is some sort of time machine
Not necessarily. Only if an observer somewhere were to have collapsed quantum wave function by viewing. Only then would the photon, which experiences no time, have ever needed to have been emitted in the first place.
Not just “somewhere,” but specifically in a sphere around the Earth that has a radius of 65 million light-years.
Potentially.
It's heartening to know that I'll live on forever somewhere in this universe.
It's "earthening" also.
Nice thought
wdym?
@@shivenlak if there is anyone out there they would see him alive even when he is dead beacuse they are looking at old light as light is taking along time to get to them and since the universe is endless then technically he would seem always alive
@@shivenlak what does wdym mean
The fact that people from thousand years ago still exist somewhere in the universe is mind-blowing
I mean, it's not like they still exist. It's more like they could be seen one way or another.
Not really, what you see of them is an afterimage or something like that
@@D00DM00D and that still exists, which is what's weird
They don't exist, their image in on journey forever.
As long as someone's watching them
So... if the universe is infinite, the light of my existence will always exist.
That's kinda cool, I guess.
Choppy you just blew my mind
Not bright enough
@@thememers_dude It sort of is. If a telescope powerful enough to pinpoint every human on earth from long distances existed, they'd be able to see us. Our light isn't bright but it exists.
@@fightzombie229 the issue is not us it everything around us is brighter

ThisIsLifespan they’d see we were here, how we ruined it, and they would decide to ignore us
Wat
They'll still see our past and wouldn't know the shit we humans have piled up...
ThisIsLifespan mean
I'm ur 250 like
It blows my mind to think that every moment in history is effectively preserved in light somewhere off in the universe, even from other planets and star systems.
what if hypothetically speaking one were in an underground bunker with an artificial source of light, aka no sunlight, incandescent light. it wouldn't be on the surface so no way to get out into the universe???
Doesn't light lose its energy after some distance so it wouldn't be travelling for an eternity in the space.
@@Ahmed-ii7up it doesn't lose it's energy photons don't decay they turn from higher frequencies and smaller wavelengths to lower frequencies and larger wavelengths which can be as big as earth.
@@Ahmed-ii7up so as long as you use a infrared telescope to observe it or observe a gamma ray because it will convert from invisible to visible light on the spectrum by strected wavelengths and lower frequency you can observe things millions of light years away.

This guy always sounds like he's on the verge of sneezing
Frrrrrr
This guy is literally the opposite of the dark skies
If you are on the verge of sneezing and want to sneeze but it starts to go away look at a bright light, it will make you finish the sneeze most of the time.
When I heard about this there was not a explanation for why this happens but a couple of theories were proposed.
The first theory is that when you look at a bright light your brain focuses on your eyes and when it sends the signal to shrink your pupil or close your eyes it diverts the attention to the sneeze to the eyes and so the sneeze automatically finishes.
The second theory is more interesting and proposes that a very long time ago far back in the human species past when they would take cover from the elements or predators or whatever else came up they would go into caves or secluded closed areas and if they stayed in there for a long time their noses would get clogged with dust or floating particles and when they went outside into the sunlight again they would sneeze to clear out their noses and throats and this became ingrained into our dna somehow.

This helped give me peace of mind about my brother that passed. His light is still out there but at some point it will fade. At some distances he doesn’t even exist yet. Beautiful.

It is indeed beautiful, but it would rather make me anxious and uncomfortable because even though thier light is still their and travelling , i could never ever observe it and relive.

Alien observer pointing to earth : " Well it's just a big ocean planet with no life, let's point on the next one"
Nah, you have to consider that if there’s aliens as smart as us, they’d realise the speed of light as well. They’d have the same conclusion as us.
@@Anas-rx9zs well speed of light is a term that is man made, humans don't know anything and we certainly don't understand scale, even tho we would like to think we do
@@boyifyouboomeimaboobooonyall
Interesting point to take in consideration, but light speed travel is the theoretical limit to any material, and no material could ever get the energy to reach it. There may be aliens out there that could bypass this somehow with other discoveries like forcefields, but its very unlikely, and the speed of light is also still very very slow to reach us from the nearest planet hosting life
As for the speed of light, the light travels back millions if not billions of years into the past so if you look at an exo planet just think that you're looking back into time
@@Anas-rx9zs the speed of light is still a fixed law that any "smart" species (assuming they are smarter than us) would know. therfore you are still right, and they would definitely conclude that their viewing earth not as it is today, but years ago. the aliens will probably fly to us in there lightspeed tech, and take a closer look in order for the light to reach them faster. atleast 10 minutes away.
Hello dude.
Imagine an alien 200,000,000 light years away seeing Pangea on Earth, traveling to see us, and seeing it in several pieces.
Keep in mind that if they were travelling in light speed it would take them 200,000,000 years to get here
@@czevzi even if they travelled 200,000,000x the speed of light, it would take them a year to even get to us. That’s crazy to think about.

Would they see it happen or would it be pangaea one second than the next second it is what it is now?

Holly crap thanks for all the likes everyone!
I have a another mind boggling comment I made on a butterfly effect video hope y’all enjoy it!
“Wait so time traveling to the past is impossible BUT traveling to the future is technically possible (time dilation) so according to the butterfly effect the future is not set (it’s random) so how are you going to time travel to the future if there is no future set? What will happen? will you create a completely new future and if that’s the case does that mean you created life a new universe based on the time traveling action, but what will happen to your original universe, will branch out and create a different future?”
Woah....Time Paradox
Bruh thats actually true
And if you teleport back to earth you can see yourself coming back from mars
If we try to consistent with physic, we need minimum 14 minutes to teleport from earth to mars, because since light is the fastest thing in universe as far as we know thus teleport should have at least same speed as light.

It would be awesome to instantly travel to 65 million light years away, look back with a super advanced telescope and watch dinosaurs roam the Earth.

@@chadgrimes252 Don't expect too much detail from 65 million light years away.
The Creation of the Universe:
Allah the Exalted said: Have not those who disbelieved seen that heaven and earth were one solid mass, whereupon We divided them and made all living things of water? Don't you want to believe? (Translation of Sura 21 Verse 30)
This verse explicitly mentions the common origin of the entire universe, a fact that was only discovered about forty years ago with the help of "nuclear physics". The separation mentioned in the verse seems to refer to what scientists today refer to as the "Big Bang." Also, as the verse also mentions, all living things are made up of protoplasm, which is 80 to 85 percent water.
Allah the Exalted said: Thereupon Allah turned to the sky which was (then) of (formless) smoke (or mist) and said to it and to the earth: "Come here, willingly or unwillingly!" They said: "We come voluntarily". So He (Allah) completed them as seven heavens in two times, and in each heaven He assigned its task. And We adorned the lowest heaven with lights (stars) (which are also) for protection. This is the creation of the Supreme, the All-Knowing. (Translation of Sura 41 Verse 11-12)
At the time the Qur'an was revealed, the word "space" was unknown and everything above the earth was called "heaven".
The word "smoke" aptly describes the primordial state of the universe, which consisted of hot, gaseous matter whose gaseous particles moved like clouds of smoke. From this matter the stars, the planets and the earth were formed.
Allah the Exalted said: We have created the sky (the universe) with (Our) power, and see how We are (constantly) expanding it! (Translation of Sura 51 Verse 48)
It is now a generally accepted fact that we live in an expanding universe.
Allah the Exalted said: Allah is the Creator of the heavens and the earth! When He decides something, He only says, "Be!" and it is. (Translation of Sura 2 Verse 117)
Allah only has to "Be!" speak to trigger an explosion (big bang).
Aside from that:
Black holes are characterized by three properties:
1. You are invisible
2. They pass at very high speed
3. They attract everything to themselves. It's like sweeping the sky
Black holes are called "giant cosmic sweepers or vacuum cleaners" in science.
Allah the Exalted said: “No! I swear by alkhunas (the unseen stars), algawar (the ones leading) Alkunas (the sweeping). (Translation of sura 81 verse 15-16)
Pulsars are rotating neutron stars.
Allah says in the Qur'an: By heaven and by the one who throbs (or knocks)! And what makes you know what the throbbing is? (It is) the piercing bright star. (Sura 86 verse 1-3)
"Tarek الطَّارِقُ" means the one who knocks. The Arabic word "Thukb ثقب" means a hole; "Thakeb ثَّاقِبُ" means the one who makes a hole. The Qur'an describes a knocking star making a hole.
Pulsars are rotating neutron stars (it rotates 30x per second!). As more matter falls into a neutron star, its mass increases, and as its mass increases, its gravity increases. But gravity is warping of space-time. A neutron star distorts space-time. The more matter falls into a neutron star, the more distortion it causes. A point is reached where the distortion would have grown so much that it caused a hole in space-time.
How could an illiterate (meaning Prophet Muhammad, peace and blessings be upon him) who lived 1400 years ago know that pulsars bore holes in space-time? That can only have been inspired by God, the omniscient.
Supernova and Iron:
One of the most important consequences of supernova explosions is that heavy elements, including iron, are thrown into the interstellar medium.
Allah says in the Qur'an: And We sent down the iron. In it is strong power and benefit for the people. (Sura 57 verse 25)
The use of the word "sent down" is very interesting. A look at the modern astronomical books that deal with the formation of galaxies and stars will give us a better understanding of the "let down" translation.
Iron alloys were already used in ancient times, but only from meteorites, which often contain the alloy iron-nickel (Fe-Ni). Since meteorites were rarely found, items made of iron were correspondingly valuable. The Sumerians called it "heavenly metal", the Egyptians "black copper from heaven".
The iron is of a strange composition. The electrons and neutrons in its atom require four times the energy potential of our solar system to be brought together. In other words, our solar system does not have sufficient structure to produce iron. Where did the iron come from then, which is found in our earth?
The scientists explained this phenomenon by saying that the heavy metals in the Universe are produced in the cores of giant stars. When the iron count exceeds a certain limit, the star can no longer carry the iron and eventually explodes (this explosion is described as a "nova" or "supernova"). As a result of this explosion, meteorites containing iron are formed and scattered. They fly around the universe until they are attracted by a planet's gravitational pull. The same thing happened to the earth tens of thousands of years ago when meteorites penetrated deep into the earth's surface and which are now known as ferrous metal!
In summary, supernova explosions are violent deaths of massive stars. The course of these gigantic explosions and their far-reaching consequences are very interesting. They are the only source of iron and other heavy metals in our solar system. They show the mercy of God, because without them life on earth would not be possible. At the same time, they can be seen as an incredible demonstration of divine power. As the Holy Quran says at the end of the verse where iron is mentioned:
Surely Allah is the Mighty, the Glorious with irresistible power. (Sura 57 verse 25)

@@efrenr81 impossible. The telescope would have to be light years long with just doing the math formulas alone.
With the density of glass, these telescopes would be black holes. It's not a possibility, it's just a imaginary scenario to visualise how we see everything in the past
Now if you were a 4th dimensional being you could be anywhere at anytime and perceive every single thing in our universe at once
If you could travel to those far away places faster than the speed of light and you could observe earth, that would be so cool.
If you could actually travel there at the speed of light, then you wouldn't see earth, or anything for that matter. You would see the end of the universe due to the relativistic effects of travelling at light speed. Or even if you travelled at 99.99999999999997% the speed of light, by the time you arrived at the far away galaxy, 7.7 quadrillion years would have passed on earth.
This is assuming however that something that has a mass can travel at light speed, which it can't, and also assuming that humans were immortal. Because even travelling at the speed of light to the galaxy 200 million light years away, you would die at some point before you got there.
sportjunky4371.....200 million × 99.99999999999997 = 7.7 quadrillion? ?????????????
99.99999999999997% percent of the speed of light, which as a value = 299792.4579999999 km/second. You don't multiply it by 200 million. I got the 7.7 quadrillion year figure by using equations that calculate time dilation. There are two circumstances where time dilation occurs, due to gravity or due to velocity (speed basically).
In this circumstance the time dilation is due to speed, in very simple terms, the person in a ship travelling at near the speed of light towards the far away galaxy experiences time slower, relative to the observers on earth. Whereas, the time on earth will appear to be moving faster, relative to the observer on the ship.
This a a simple explanation because i'm not very good at explaining relativity, but if you look up "what causes time dilation" or "explaining Einsteins theory of relativity" on CZcams, you'll get some good explanatory videos.
It has a lot to do with the fact that the speed of light is constant no matter what.
Due to time dilation, somebody travelling on a hypothetical circular track on earth near the speed of light, could travel for a week at that speed and when they stopped, slowed down and hopped out, (assuming they were still alive) they would have only aged one week, however the rest of the earth they were travelling on would have aged hundreds, potentially thousands of years depending on how close you get to light speed. Basically meaning they have travelled into the future while only ageing 1 week.
So back to the original example, using Einsteins equations, you can calculate the time dilation for somebody travelling for 200 million years at 299792.4579999999 km/s. While they would experience 200 million years of time, earth would experience 7.7 quadrillion years based on the result of the calculations. Obviously a human can't live that long, so they would never reach the galaxy. However hypothetically, if a human were to be born and die on this ship, lets say they live their entire 100 year life on board. In that 100 year life, 3.7 billion years would have passed on earth.
Now don't think highly enough of me that i used these equations myself to calculate this, I didn't. There are calculators on websites that can do it for you. You just put in the speed travelled as well as the length of time and it tells you how much time would have passed for a relative observer.
Another crazy thing is the fact that forward time travel is not only possible due to this, it happens every second of every day.
Anything that has a velocity experiences time dilation, when you fly you experience it, when you drive a car you experience it, when you walk you experience it, when a snail moves ever so slowly it experiences it. It's just that at these speeds the time dilation is pretty much unnoticeable. But when travelling at very fast speeds especially nearing the speed of light, it becomes very noticeable.
Simply a bend in space time could make the traveler go faster than the speed of light because they would be breaking typical travel times to those far away places. So they wouldn't be actually going the speed of light or faster, they would just be taking a short cut.
True, bending space time is a theoretical concept. Have you read about the Alcubierre warp drive?

the speed of light is the speed of light because that's how fast the universe loads

Space moves faster than light does.
The speed of space expansion or dark energy, is something cosmologists are still trying to understand. The end of the dark energy story has the space within an atom (which is mostly just space anyway), expand. This would happen to every atom in the universe.
We have observed the effects on the macular scale as we continually observe nearly every cosmic neighbor flying away from us.
Light speed is certainly crazy fast, but still limited. Distances in space are vast compared to our level of travel. In order to move at the speed of light, one has to become massless, or photonic.
We are obviously not massless and it would take an infinite amount of energy to get close to, but never reach the speed of light.
Learning how to manipulate space itself as the means of propulsion, such as the Alcubierre drive; would be far more effective if we ever make it to becoming an interstellar race.
no, its the law of causality

Really hit me when you mentioned that everything you see around you is how it was, not how it is.
TheFunOfGaming Yea.....
TheFunOfGaming I hope thats a bunch of bullshit & that scientists are guessing because thats devastating that aliens can't see modern humans
Me too.
Ahmad X it's not bullshit, the speed of light has been measured and it takes time for light to travel
ITS LIKE REAL LIFE LAG.
When you learn more in CZcams than in school
Your right..and its awesome i told son if ever die and i didn't teach you yet..just google it..and also i think school at this point is so the kids have something to do while the parents are working..lol
I took astronomy classes in middle school and never understood what light year meant.. watched few youtube videos and now i just wonder how hard was it to those teachers to explain it lol
_You're not learning anything with the garbage he just spewed. EvoBangBangs gotta mix in their stupid Napkin Ideas into facts about light speed._
_Evotards: The continents were at one time all connected and it was called Pangia"
_Hey dumbasses......ALL the continents are still connected. xD_
you wouldn't be able to learn anything from CZcams if you were illiterate... Lol
Yeah they teach us *-(EVERYTHING)-*
*You can't see anything in the universe as it is now*

"you would be seeing him 0.03 nanoseconds in the past" thanks Astral, now I question my existence.
We are so small. Incredibly small...
*I look in my pants* "yeah, I guess you could say it that way..."
Zach Reloaded small like ants.. but ants are smaller than us
We are so huge, so massively huge... only a single one of our skin cells contains 100,000,000,000,000 atoms. And one proton is 60 000 times smaller than the smallest atom (hydrogen). And a quark is 2000 times smaller than proton. And an average human body has like 8,000,000,000,000,000,000,000,000,000 atoms, mostly much bigger than hydrogen atoms (carbon). Our body is like an entire universe to a quark. Oh, and just at the time of the Big bang, our whole universe, all matter and energy around you and in your body, atoms of your and my body and everyone elses were compressed to even smaller space than atom. Even all forces of nature (gravity, electromagnetism, weak and strong nuclear force) were compressed to one superforce, before they split apart just after the big bang, three space dimensions and time dimensions were one superdimension. All this is rigorously tested and proven to be true, mindfucked yet? :D Doesn't matter anyway, there it yet to be proven that we aren't even real. All matter and energy is just information, so we are 1's and 0's in a simulation in huge quantum computer and our minds are just intuitive programs.
Speeds are relative. While the Moon rocket, reached 25,000+ mph, It is also in a solar orbit around the Sun. The solar orbit speed is about 66,000 MPH.
We are a grain of sand in a beach
This is probably why we haven’t seen other life, everything’s just happening in different universal time zones
Hanlon hanlon just think. All the other earth like planets we have found are thousands of years old. They could have live just like us by now. Maybe they were very primitive but have andvanced like us?
Jordan Wilson Hell yeah that’s honestly the craziest shit to think about
I want believe!
In a way... yes
No
“We are so close to being able to travel close to the speed of light”.... finds out that warp drive could be possible and it goes 10x faster 🤯
I’m so high
So that means how we see the Kepler planets now are in the past? so that would mean maybe life has already developed there
Glitched SharkMusic Yes. If something is 100 light years away we see it as it was 100 years ago.
Glitched SharkMusic or worst, they've been wiped out already
Yes, could have developed and already been erased.
Well, since we would have no way of knowing whether life might have developed there even if we were seeing them in real time, what's your point?
we'll never unfortunately meet other life unless its in our solar system
3:15 *because light forbskrbskbrkanf*

if they put a telescope four light years alway from the Earth right now, maybe they will see you making this video
That's quite the most amazing video.
"you can never see anything as it is now:
whoaaaaaaa
haha
If you looked at earth from 300 million light years away youd still see dinosaurs on the earth. Pretty damn cool. Also if the sun were to go out we wouldn't know for 8 minutes

There’s nothing that honestly interests me more than space. Sure, we all get caught up in our lives. But I can never grasp that this is the reality we live in, and how very little we know about it. Terrifying yet so amazing all at once.
@@Beyondlimits_400 Same. I like to think the Universe/galaxy is like Love. It's beautiful. I can't explain it. It's scary. It's a mystery. It's hope. It's light. It's dark. It's endless. It will hurt and kill me. It grows. It takes my breath away... It's the only moment my insignificant self gets pulled by it's gravity just so my soul can dance in harmony with another. I can be around it forever...
Thank you - what a fabulous perspective !
This could explain how when you look at the sky and see a plane on your right the sound comes from the left or any other direction since we perceive things in the past. This is a good theory that could explain most things such as time dilation.
@@TotallyTotality It's so weird. Light travels extremely fast while sound is nowhere near. So that's probably why the human eye can see things like that. Such an interesting world we live in.

Nature you mean, science is just the study of it
So (this may be a dumb question) but if we would be able to find a wormhole and built that big of a telescope on a planet that far, we would be able to see the past ?
Aron Moll you're assuming a wormhole transports matter faster than light; which goes against all laws and is not proven to be true. So I'd say no, but if you could do all that, then yes you'd be able to see in the past
Poseidon thanks! And I know that there is no evidence of wormholes, but just assuming they are real for a moment:P
Aron Moll yeah I figured you were speculating :). It would be cool right, being able to see in the past?
Assuming you're able to produce and transport a massive telescope faster than the speed of light on demand, then yes, you could see the past. That assumes a lot tho.
Unfortunately this information is incorrect. It is impossible to traverse spacetime FASTER than the speed of light. What a wormhole is theorized to do, is basically make a "shortcut" through spacetime. If the wormhole goes from one side of a galaxy, to the other, you can travel through the wormhole at much lower speed, but arrive at the other end of the wormhole before light has reached there yet. Less distance to travel.
You know somthing insanely Massive when even the fastest thing seems slow
One of the coolest videos I've ever watched! Super interesting to think about.
Just think. We could rewrite history if we were able to work this stuff out. We could hear of a murder and travel a distance and watch the crime scene and know exactly what happened.
There's literally a movie about this, Minority Report.
Plexiate We can see who said the n word?
Re-writing History means that you won't have that time machine because of the butterfly effect. It would over-write your own timeline, and you would be stuck in the past eternally.
Plexiate You can't rewrite an event, the event has already happened, it's just that we see it (say you were on Mars) 4.6 minutes later
If we could travel that far, I think we would have bigger things to worry about other than things happening on Earth.
Now this is kinda like time travel, never thought about it this way
Gat Sharon I mean time zones are like that. :)
Gat Sharon it is! Also mass and high gravity eventa like a singularity in a black hole, can dilate time! So a day clo se to that BH is like 2 years ln earth
Yes I just realized it too. With a fast enough spaceship and big enough lense you Will be able to "Chase down" the light emitted from certain events in history and look excactly how they happened.of cause this Spaces ship would need to travil superphotonic 🤔
Gat Sharon somewhat, but not the typical idea of time travel, you won’t see people on another planet as such in the past as for them they’d be in the present. It’s just because they’re out of our made up times
Yes, but you would only be able to watch
Hey I love this video you just released, greetings from Proxima II.
An Alien a couple light years away seeing earth in 2016: aww what a happy planet they seem to be peaceful
Earth : CoViD
build warp drive, travel 70 million light years away from earth, build a gigantic telescope, and observe the dinosaurs
juki0h tuki I guess not. you then already travelled for 70 million years from earth. thus viewing back here will approximately 70 Million years in the past also. then you probably would see yourself in your house viewing this video. not dinosours..
unless you travel instantly your logic is flawed.
he said warp drive not at light speed.....
even at max warp it would take thousands of years to travel that far
Time and speed are relative so even if you travelled instantly you would have went 70 million years into the 'future' from your perspective so earth would look the same as when you left.
Everytime you say something it sounds like it’s your last breath
eZ Gold lmao
This made my lose my shit lmfaoo
Learn another language and try to speak it perfectly asshole
@@goodknight6828 Why u butthurt bruh it's just a joke😂
eZ Gold hahahah
Wow... amazing knowledge, thank you
So the universe has input lag
If we can teleport to another galaxy 60 million light years away then we can observe all the dinosaurs and watch how they ate, what they did and looked like!
haha this guy is explaining a telescope using the old fashion way to do it. I read a book about this and they have computers that align the glasses better now and they use infrared and x-rays to see stuff. They probably could focus light somehow with better technology in the future. We wouldnt be able to see the dinosaurs because the sun would be so bright you can barely see earth (like other stars) but with better technology we could probably do so. But I wonder if the light fades our or preserves its image forever and travels forever? The light from other galaxies come for 2+ million light years away so I think so as tricky as that is.
GENIUS
Wouldn't a trillion meter telescope collapse into a black hole
Psycho Steven Universe Fan ohhhh true maybe
That has actually been debunked a while ago lol. Don't know the exact explanation but from what understood, that is not possible because you're looking very close at the specific planet etc. Should look it up 👍

Great explaining!
"Everything you see around you is how it was not how it is now, you can never see anything how it is now but only in the past" That's a real brain jogger.
Pope Records And the crazy thing is that it’s true, what we see around us only seems like it’s in the present bcuz of how fast the speed of light is so we just generally assume we’re viewing the present life
MR POPE, IF SOMEONE SAID HEY, SHOW ME A PICTURE OF YOU WHEN YOU WERE YOUNGER, SAY SURE. THEN TAKE A SELFIE 😂
this somehow made sense
Every time I watch a video like this my mind gets blown on how insignificant and small we really are.
Well said. But...we are constantly waging wars..so as...to self destruct.... that's the vanity of humanity... probably.
Size doesnt matter we can stilll seee thousands of light years far
@@swapandas1273 Thats why we must not self destruct so as to continue to be able to see for years to come and if it is possible, in that case ( of non self-destruction), to colonize the galaxy (for starters).
Thank you very much for this material. It is more than useful and interesting.
thank you for explaining about the distance of light years. it opened my mind about the facts and still learning about the past. though it's bursting my mind and sometimes im feel scared thinking about all of these.
Imagine traveling faster than light to a point where you see earth millions of years ago and looking back and seeing what dinosaurs actually looked like
Aliens could be looking at us 100 million light years away from us at this very moment and instead of seeing us they would dinosaurs chilling
Would be like watching a video on rewind.
@@MG-fc1zg how does that make sense
If you travel faster than light you would be able to travel through time enshtine proved it
@@l750z_6 bc if they're looking at us from a planet that's 100 million light years away from earth. Then light from earth takes 100 million years to reach them and so they would always be viewing the earth 100 mil years ago. So they would basically see dinosaurs with a strong enough telescope
So if the sun disappeared it would take 8 minutes for earth to turn dark?
Not inputed
That's a correct assumption.
Yes
*Decidous* Yup....slightly less if the sun would fart.....🌞💨
Yeah even if the sun exploded
We would only know 8mins later
Ye
This is fricking mind-blowing, you telling me if someone can spot us from a million light years they can see our ancestors?
