@@TheChillzoneX Quantum Teleportation to other planets and back with data sent to Earth, and the data becomes an image or video, or 3D volumetric hologram, idea. Also another idea is using large lasers like the military has, for Quantum Teleportation as the laser would be pointing at Proxima B in the solar system Alpha Centauri, which is closest to us, about 4.3 light years away from us. Quantum Teleportation can go 3 times the speed of light with Photons, have it take a year to a year and a half to get there, and then send the data back in a year to a year and a half, 3 years going there and back, and then when the data gets back to Earth, have it create an image or video, or 3D volumetric hologram, e.g. imagine how fast a Quantum Computer can simulate planets, asteroids, and other things. Imagine Quantum Teleportation with Mars and beyond, Proxima B the planet and beyond. And now imagine as Quantum Teleportation matures, it could be 20 times faster, 50 times, who knows. And to mention as Quantum Teleportation matures, with breakthroughs, sending it again to Proxima B so much faster, and beyond to other solar systems in our Galaxy and beyond that. ------------------ One other idea, is using Quantum Teleportation when it matures, to send "large objects" that aren't alive, like devices, machines, vehicles, buildings / structures, and so on to Mars, Proxima B and beyond. So that it sends them fast enough for cargo and other needs, using satellites, not just for the Quantum Internet across other planets.
You all prolly dont give a shit but does anyone know a method to get back into an instagram account? I stupidly forgot the password. I would appreciate any help you can offer me
This reaction just makes me want to see The Chill Zone react to "The History of The Entire World, I Guess!" by Bill Wurtz. (It's got quarks and stuff!)
When you paused it at the moon landing I thought "if a physics student is about to say Apollo was a hoax, I'm gonna flip my shit" Thankfully, no shit was flipped.
I've watched the video a couple of different times, be it showing it to someone, or through reactions, and this has to be the most pleasurable experience of watching it. I know the basics of the information, but having much more of a scientific explanation/definition is seriously interesting.
Not only was this entertaining to watch, you have emparted some new knowledge to me. I'm old enough that we never learned of Higgs field, leptons, quarks and such in school. So thank you for this info and sending me down a wonderous rabbit hole.
I watched several reactions on this video, and yours is only the second that I can appreciate. Someone that understands what he is talking about, and furthermore, someone who can actually add to it. That is great, thanks for your reaction.
NIce to see a more scientific minded reaction to this video. Following in the same fashion, it would be extremely interesing to hear your insights on this video: ''TIMELAPSE OF THE FUTURE: A Journey to the End of Time (4K)''. The 30 minute video (version) goes mindbogglingly deep into potential future timelines for all of space and also touches upon various philosophical physics concepts. So far, it seems no people with actual physics background (on youtube) have made a reaction to it.
I am in the middle of reading a few physics books (I started with Brian Greene's, since they were recommended as "starter" books in a way) so I actually appreciated your occasional breakdown of things every now and again. And I actually understood them which is even more fun lol. Subscribed for the interesting info!
Just found your channel....This is great stuff and I'm loving it. Hope your channel blows up and get big because this is great content! cheers and have a nice weekend!
I always like to use Elite Dangerous as an example of scale. An online live-service MMO that's incredibly close to a 1:1 scale of the Milky Way. Seven years later, and hundreds of thousands of players all with the ability to travel over 30x the speed of light, and still less than 5% of it has been explored. And that's just our tiny little galaxy, in a tiny little cluster, in a tiny little supercluster, inside another tiny little supercluster, inside our tiny little observable universe. Space is beautiful.
There's an error in the original video regarding the time to travel to Proxima Centauri. Traveling a distance of 4 light years at 100kmph would take roughly 46 million years, not 6x longer than the age of the universe. The original poster also makes the claim that the star would not still be there by the time you arrived (I assume like in his moon example the distance is a fixed value and the star does not orbit the galaxy); however, interestingly, even if the travel time were 6x longer than the current age of the universe, Proxima Centauri is a red dwarf star of 0.12 solar masses. Red dwarfs have main sequence life times expected to last trillions of years. (That's thousands of billions of years). Being far beneath the Chandrasekhar limit, when the main sequence ends in a few trillion years, it will then live on as a white dwarf with a degenerate helium core only capable of radiating away its remaining heat as the star has insufficient mass to start helium fusion. It could then take tens of billions of additional years to cool to a temperature that emits no visible or heat radiation to become a black dwarf. This low mass black dwarf would effectively live on forever assuming protons do not decay in the extreme far future.
A few questions. What physics classes are you taking and how long are they? How old are you and what is your goal with taking these classes? I'm 26 at the moment and I've always been heavily drawn to science but in the recent year I've found myself to enjoy science more than ever, mostly astrophysics and space in general. I would like to dig deeper into these subjecs and educate myself further, is there any merit with taking a class or can I just learn this stuff on my own?
Hi. General course aside ( relativity, math physics,statistic physics) I chose to work with analytics, so everything that required me to code essentially. I had to astrophysics courses last year: Introduction to Cosmology and Extragalactic Astrophysics. Cosmology is one that I think you can learn on your children own, while Ex.Astro requires a guiding hand. Fx. We have to work on Gia Data ( a galaxy that collided with our milky 10 Bi. Years ago) and determining, the dynamic or chemical evolution, is not a walk in the park 😅
Thank you!!! Thank You!!!! for your Reaction. The first intelligent person to react to this video. And believe me, I've seen a lot. We always talk about whether there is intelligent life out there. When you look at all of these Reacts, it's hard to believe that there is intelligent life on earth. Thank you for giving me back my faith in humanity :)
Bruh even if we had the speed that is 93 million times faster than the speed of light it will still take 1000 years to go from one end to the other end of our observable universe
Have you seen "Timelapse of the Future" by Melodysheep yet? It's very physics-y and mindblowy. You would probably also like Kurzgesagt--specifically, I'd recommend videos such as the one about Earth getting kicked out of the solar system, the Kardeshev Scale, how to build a Dyson Sphere, what happens if we bring the Sun to Earth (nothing good!), what would physically happen if the entire planet turned to GOLD...stuff like that. :)
Man. I want to study physics after CS but holy moly. I am so lazy and spent way too much time on YT and Twatch. But videos like this get me motivated again.
I appreciate your well-informed reaction, you obviously know your stuff. The video provides a lot of information and you provide context for people to better understand what they're learning. Well done. With that said I would like to add to the question "why haven't we gone back to the moon?" Lest we forgot that most decisions made on such a large scale, especially involving risk of death, are always ultimately politically motivated. I'm sure most people know of the story of The Space Race. Without competition motivations become stagnant. This is even true in nature itself via natural selection. Competing for resources is what drives us forward economically.
I don't understand. I was always told the Sun's light takes 8 minutes to reach Earth. So then, why would a message from Mars take 20 minutes, going light speed to reach Earth?
It depends on the positions of Earth and Mars, the average distance between Earth and Mars is not the same as the average distances between the Sun (1 AU for Earth and 1.5 AU for Mars). The average Earth-Mars distance is around 1.7 AU. It takes radio signals around 14 minutes on average to travel between Earth and Mars (It all depends on their positions). Applying similar logic you can see why Mercury is the closest planet to every other planet in the Solar System on average.
"Light does in fact have mass." Wait, wait, wait, wait, wait... WHAT!!? You can't just upend my whole concept of really like that, and then move on like it's nothing. Since when does light have mass? Please explain. P.S. Great video.
Light is made of photons, which it's true " are massless" but... From the famous E= mc^2 for the energy og light , where does the mass component come from. These become interchangeable, when we are in relativistic territory ( light speed ) The typical concept of mess, is from inertia, the mass at rest. A simple of thing about it is...how com light push object? Well it most have momentum, which is equal to kinetic energy, which involves a moving mass, but at light speed the energy of subatomic particles is the same as their mass.
Flack bodies have nothing to do with stars you can see with naked eye (meaning no assisting equipment like telescope). Any star beyond area he showed is way too small and/or dim for your eye to see without for example good telescope.
Correct me if I'm wrong but, AFAIK, the scale-factor to reduce from human size down to sub-atomic particle size is greater than the scale factor from human size going up to the size of the observable universe. So, a human would seem bigger to a sub-atomic particle than the observable universe seems to us.
If a species can travel very fast, then they don't need the "far away light" to reach their planet in order to see that light. They can travel to very far places and view the "far away light" from that location. They would in theory be able to see what we currently call the "unobservable" portion of the universe (if they can travel very fast.)
finally someone smart enough to understand this video all the other I saw are too stupid to understand a thing , they alway say " it's impossible " or " how the scientist can know all this" "there is something they don't tell us ..."
The numbers are enough for me to imagine it, but a lot of people are visual learners. I just do the math (to a point, not on a cosmic scale, that's where a visual helps)
In other words we almost desperately need a quantum theory of gravity (unless we conclude that space and time is not fundemental and therefore gravity which is the curvature of spacetime is also emergent and not a fundemental force).
I hope that at some point we can develop a powerfull Alcubierre drive with resonable energy requirements, something in the range of theoretical AMA generators, the new research does look promising, evern the need for negative mass has been eliminated(although if i read that correctly one group has already created negative mass from a bose-einstein condensate). If this becomes true, we might be able to explore regions beyond the observable universe in the next billions of years(unless we make us go extinct which is probably more likely lol)
You're the best out of every dumb people react to this informative video. Their brains are not load and crack the information. But you're really good at this. I love your reaction. 😘😘 You make my day and night. Other people just disturb my brain when some dumbest dumb people say that this video probably not true 😂😂😂😂..
Can you, in layman's terms, explain to me how the planets Uranus and Neptune were mathematically predicted before they were actually observed? I can't wrap my head around it...can any of you?
I can see that you are still a student (when you made the video, hehe). Just reciting what you have lerned :). No worries maybe you are doctor now (I haven't seen the whole video when comenting yet. (look at Cédric Villani's "presentation"... you can find it on CZcams). He was a minister in France for a while. But he got the fields medal... yep, I don't know why there isn't a Nobel price for maths. It it a conference, 6 hours long... I stopped after one hour and the audience composed by doctors in physics and amthematics almost all whent away because it was to complicated (I am a doctor and I didn't unnderstand half of it... sorry, I am not a English native speaker hehe)
How would its revolution effect building? If we could get a livable place on the moon, we could build things there that would be impossible on Earth. At least scale-wise.
Well, actually also not because of this. The reason is much simpler and it's the different speeds of Earth and Mars. As the video mentioned the average distance is 200 mln km. this means that when the Earth and Mars are on the same "side" of the sun the distance beetween them is 200mln-150mln = 50 mln + X km (where 150mln=1AU) and when the Earth is on the opposite side of the Sun the distance will be 200mln+150mln = 350 - X mln km. (Yes i know, I use here this 200mln in a very not scientific way and it does not make much sense, but it illustrates the concept)
@@16PiotrEX Totally aggree. Of course they travel at different speeds. Thats why they end up on opposite sides and on the same side. My point is another one: I am saying that it has nothing to do with eccentricty as mentioned in the video. Even Mars is very close to a circle.
Well, I don't know about big companies going after that oil anymore. With renewables getting cheaper and cheaper (for example solar is cheaper than coal (The entire coal industry is collapsing btw) now, and continue to get cheaper everyday), oil, natural gas, coal, and everything that isn't renewable are becoming economically unviable. Not to mention the fact that public opinion is largely in favor of renewables and largely opposed to non renewables. Plus renewables are cheaper to maintain, and give you energy independance.
I don't understand one thing. Dr. Alan Guth refers to the speed of light. Shortly before, however, it was said that there are regions in space that move faster than light. Wouldn't that mean the formula is wrong and the universe is even bigger? Or and that is also very likely my math knowledge is reaching its limits here;)
Well, yes and no? The inflation of space is getting progressively faster, and since space itself doesnt have mass intrinsicly, doesnt have to be confined to the speed of light
When you see how truly Massive it all is I find it just ridiculous to think that Earth is the only planet with Ice cream. Seriously, Thats just ridiculous. Oh, and life by extension as well I suppose.
No. Single celled and multi celled organisms like bacteria have already been discovered on other space bodies like meteors. There is life out there. And given how enormous space is, it's foolish to think we are the only advanced species to exist. Statistically speaking, it's likely there are dozens of planets somewhere out there with animals or even human like creatures just like Earth.
This is the best reaction I've ever seen to this video. He knows what he's watching. Other dumb people just say know i don't believe and how can these scientists know this. They are dumb and don't do their research
Observable universe is 93 billion lt/y across and if the universe is only 13.9 billion years old how did that light have the time to travel to here? 46.5 billion years of travel at the speed of light have happened if we can observe that light ....../ Think about that. So how old is it?
... and that's why I do believe in "Aliens". So many stars/suns, so many planets and stuff out there ... somewhere out there in that huge system must be life! :-)
Yes, but no. There are relativistic corrections applied here. I'll have to got back to my fort physics course to explain that correctly, but the jist is that from the observers point of view it seems like the object is morning faster than light, while in actuality it's just getting infinitisimaly closer to light speed. Fx, from observations we have found HD 140283 aKa methuselah a star older than the universe ( doesn't make much sense), by analysis the mentality. These are the few things that keep physicist awake at night...
Gee, you're a real smart guy! So smart you know everything! You know so much that I don't have to subscribe to your channel. BTW you don't have to be a smart ass.
14:20 this animation makes no sense. It’s a model of the Milky Way... yet the background is the view of the Milky Way from within(our night sky) lmfao that makes no sense at all. This would be like having a model of the solar system and in the background you can clearly see the sun or the earth 😂😂
I kinda wanna ask you about your religious (or possibly lack of) views, but I realize the youtube comment section isn't necessarily a great place to. You being a physics student and all
Hehe, I get that a lot. Well yes I am Christian. But I was the least likely person to find myself believe in a higher power. Thing I approach my belief the same way I do my studies. Since I wouldn't be able to call myself a physicist ( after I get my bachelor's degree) without understanding the terminologies thoroughly, I should do the same with the bible. So spent a year studying the bible, understanding the parables and putting it all together, before I could say "I believe in God".

i spent the whole video trying to determine where he is from
when did Tyrone Magnus start talking with a British accent?
Lol
I’m pretty sure he lives in Copenhagen. That isn’t a British accent my friend. XD
Correct me if I'm wrong but, AFAIK, the scale-factor to reduce from human size down to sub-atomic particle size is greater than the scale factor from human size going up to the size of the observable universe. So, a human would seem bigger to a sub-atomic particle than the observable universe seems to us.
The sky and cosmos are one
The r is pronounsed in Artemis its a name from acient greek But the r is meant to be pronounced
If a species can travel very fast, then they don't need the "far away light" to reach their planet in order to see that light. They can travel to very far places and view the "far away light" from that location. They would in theory be able to see what we currently call the "unobservable" portion of the universe (if they can travel very fast.)
finally someone smart enough to understand this video
all the other I saw are too stupid to understand a thing , they alway say " it's impossible " or " how the scientist can know all this" "there is something they don't tell us ..."
30 Earths between us and the Moon is pretty cool but you can fit all the other planets in our solar system between us and the Moon too.
Sun: You mad tiny earth.
Earth: And you think your big, haha.
STEPHENSON 2-18: Well, Hello there.
Galaxy supercluster : oh hi atom sized object
@@JupiterVortex Entire universe: Oh hey, super incredibly tiny clusters :))
@@phammanh2689 Multiverse Foam: *PATHETIC*
Im sure Pioneer is out further than the one in the video now.
I was jut searching a guy who have a science degree.....to see
Thanks for your reaction....😊
So when you said gigayears. I instantly thought gigabyte. Wtf, bruh.
You don't use parsecs and gigaparsecs?
The Universe is not expanding uniformly. The expansion is speeding up and varies depending on where you look (measure).
The numbers are enough for me to imagine it, but a lot of people are visual learners. I just do the math (to a point, not on a cosmic scale, that's where a visual helps)
you're hella smart
In other words we almost desperately need a quantum theory of gravity (unless we conclude that space and time is not fundemental and therefore gravity which is the curvature of spacetime is also emergent and not a fundemental force).
If you arent going to be best astronaut ever im going to be .... do what you want your intellingence ....
I hope that at some point we can develop a powerfull Alcubierre drive with resonable energy requirements, something in the range of theoretical AMA generators, the new research does look promising, evern the need for negative mass has been eliminated(although if i read that correctly one group has already created negative mass from a bose-einstein condensate).
If this becomes true, we might be able to explore regions beyond the observable universe in the next billions of years(unless we make us go extinct which is probably more likely lol)
You're the best out of every dumb people react to this informative video. Their brains are not load and crack the information. But you're really good at this. I love your reaction. 😘😘 You make my day and night. Other people just disturb my brain when some dumbest dumb people say that this video probably not true 😂😂😂😂..
You can actually fit the rest of solar planets between earth and moon.
Mars actually has liquid water on it
Can you, in layman's terms, explain to me how the planets Uranus and Neptune were mathematically predicted before they were actually observed? I can't wrap my head around it...can any of you?
I can see that you are still a student (when you made the video, hehe). Just reciting what you have lerned :). No worries maybe you are doctor now (I haven't seen the whole video when comenting yet. (look at Cédric Villani's "presentation"... you can find it on CZcams). He was a minister in France for a while. But he got the fields medal... yep, I don't know why there isn't a Nobel price for maths. It it a conference, 6 hours long... I stopped after one hour and the audience composed by doctors in physics and amthematics almost all whent away because it was to complicated (I am a doctor and I didn't unnderstand half of it... sorry, I am not a English native speaker hehe)
How would its revolution effect building? If we could get a livable place on the moon, we could build things there that would be impossible on Earth. At least scale-wise.
04:08 mister student in Moon are only 50-100 metres deep under ground Helium 3 . = one ton He3 get energy of electric power for 3 years need of USA.
Molten rockets?
10:00 In fact, here you are wrong. Giga-year is time. Light-year is distance! But great distances can be in giga-light-years.
@6:55: well, not ao much due to kepler, more due to min, max, ave distances of two different orbits with approx. 1 - 1,5 AE.
Well, actually also not because of this. The reason is much simpler and it's the different speeds of Earth and Mars. As the video mentioned the average distance is 200 mln km. this means that when the Earth and Mars are on the same "side" of the sun the distance beetween them is 200mln-150mln = 50 mln + X km (where 150mln=1AU) and when the Earth is on the opposite side of the Sun the distance will be 200mln+150mln = 350 - X mln km. (Yes i know, I use here this 200mln in a very not scientific way and it does not make much sense, but it illustrates the concept)
@@16PiotrEX
Totally aggree.
Of course they travel at different speeds. Thats why they end up on opposite sides and on the same side.
My point is another one:
I am saying that it has nothing to do with eccentricty as mentioned in the video. Even Mars is very close to a circle.
@@logenninefinger3420 Oo, than I misunderstood you. And yes, you are right those orbits are almost the perfect circles.
Cuba gooding jr.? Is that you bro?
Well, I don't know about big companies going after that oil anymore. With renewables getting cheaper and cheaper (for example solar is cheaper than coal (The entire coal industry is collapsing btw) now, and continue to get cheaper everyday), oil, natural gas, coal, and everything that isn't renewable are becoming economically unviable. Not to mention the fact that public opinion is largely in favor of renewables and largely opposed to non renewables. Plus renewables are cheaper to maintain, and give you energy independance.
I don't understand one thing. Dr. Alan Guth refers to the speed of light. Shortly before, however, it was said that there are regions in space that move faster than light. Wouldn't that mean the formula is wrong and the universe is even bigger?
Or and that is also very likely my math knowledge is reaching its limits here;)
Well, yes and no? The inflation of space is getting progressively faster, and since space itself doesnt have mass intrinsicly, doesnt have to be confined to the speed of light
When you see how truly Massive it all is I find it just ridiculous to think that Earth is the only planet with Ice cream. Seriously, Thats just ridiculous. Oh, and life by extension as well I suppose.
OOOOOOO I HEARD THERES OIL IN MARS! DAT SHIT IS MINE!!!
Said America calmly
Alright i will be the one to ask....
"ARE WE ALONE IN THIS UNIVERSE??"
No. Single celled and multi celled organisms like bacteria have already been discovered on other space bodies like meteors. There is life out there. And given how enormous space is, it's foolish to think we are the only advanced species to exist. Statistically speaking, it's likely there are dozens of planets somewhere out there with animals or even human like creatures just like Earth.
@@Turtlezzzzzzzzzz well if we are alone in this universe is such waste of space
@@wickedrabbit1173 we are not alone in the universe there are other singular and multi cellular organisms on other stellar objects
No the night sky is just a lack of photons.
Are you from the Netherlands? Your pronunciation and word choice sounds like an English second language speaker whose home language is Dutch.

WATCH BIG NUMBERS BY NIEL DEGRASSE TYSON
This is the best reaction I've ever seen to this video. He knows what he's watching. Other dumb people just say know i don't believe and how can these scientists know this. They are dumb and don't do their research
Dude, the whole video made me depressed😭
Why lol
I still think the moon is RELATIVELY close.
If you scale down the observable universe to our solar system, the moon would be about 0.1 micrometer away from earth. That's relatively close indeed!
Observable universe is 93 billion lt/y across and if the universe is only 13.9 billion years old how did that light have the time to travel to here? 46.5 billion years of travel at the speed of light have happened if we can observe that light ....../ Think about that. So how old is it?
Talk talk
... and that's why I do believe in "Aliens". So many stars/suns, so many planets and stuff out there ... somewhere out there in that huge system must be life! :-)
О черт, они эволюционируют.
You should take a look at what Melodysheep has done, his Timelapse ofthe universe has over 40M views on youtube
21:50 I thought you couldn’t travel faster than the speed of light?
Yes, but no. There are relativistic corrections applied here. I'll have to got back to my fort physics course to explain that correctly, but the jist is that from the observers point of view it seems like the object is morning faster than light, while in actuality it's just getting infinitisimaly closer to light speed.
Fx, from observations we have found HD 140283 aKa methuselah a star older than the universe ( doesn't make much sense), by analysis the mentality. These are the few things that keep physicist awake at night...
An object cannot travel the speed of light, but the fabric of spacetime can. Space itself is expanding faster than light.
Just think by the time I finish this comment the universe has already expanded further than I ever will travel

You edited this? Why didn't you put your face out of the video frame, over to the right?
What courses did you have to take? Were you a calculus and trig master in highschool?😅😂
Cosmology and astro 4 aka Intergalactic Astrophysics. Was calculus
@@TheChillzoneX that sounds way cooler than anything i took in school🤣
Gee, you're a real smart guy! So smart you know everything! You know so much that I don't have to subscribe to your channel. BTW you don't have to be a smart ass.
How did you get to be a physics student and not know at least some of this stuff.
? He talked about most of the shit
14:20 this animation makes no sense. It’s a model of the Milky Way... yet the background is the view of the Milky Way from within(our night sky) lmfao that makes no sense at all. This would be like having a model of the solar system and in the background you can clearly see the sun or the earth 😂😂
I kinda wanna ask you about your religious (or possibly lack of) views, but I realize the youtube comment section isn't necessarily a great place to. You being a physics student and all
Hehe, I get that a lot. Well yes I am Christian. But I was the least likely person to find myself believe in a higher power. Thing I approach my belief the same way I do my studies. Since I wouldn't be able to call myself a physicist ( after I get my bachelor's degree) without understanding the terminologies thoroughly, I should do the same with the bible. So spent a year studying the bible, understanding the parables and putting it all together, before I could say "I believe in God".
@@TheChillzoneX Very well put. Thanks for the reply and insight
He actually beliefs in the big bang 😂
The average american drives 21726 KM a year. 17 years of driving will be equal to driving to the moon lol
Actually, the communication times from Mars would be zero. The technology exists to communicate without transmissions.
