"The homework was too hard, so I spent the night trying to figure out how to go at the speed of light so time would stop, and then the homework would never be due."
What I always found fascinating was the time dilation. When a light particle is created from our vantage it can take thousands of years to escape the sun. Then about 8 and a half minutes to get to the earth and the back of your eye where it annihilates. But from the particles point of view due to time dilation it would be instantaneous. Thus creating and annihilating at the same time. Drawing out a null line. A distance crossed in zero time. This one little thing in relativity melted my brain.
That is because the only real constant in the universe is the one thing that we still do not truly understand. gravity. Time, and therefore, the speed of light is only truly relative to gravity.
One thing that always fascinated me about this concept is that, from the photon's point of view, it only exists for a timeless instant as a line connecting its creation point and its endpoint. This means that the endpoint of the light beam effectively exists as a beam that crosses time as well as space, since the endpoint is in the future of the creation point. It's mind-bending to wrap your head around.
It's all hypothetical, so, he is my interpretation. If light has life, it's processes would be effected environmentally. Thusly, to me, light would be capable of thinking and processing that information as fast as say, itself. So, upon that thought, it would be be 'being, living, etcetc' as we do. So around it (this living light) it would see everything frozen in time around it.....🐻 Really hoping for someone to carry this thought forward or backward for me. My brain hurts after fiction/factional thinking's🐻
Another way to think about it is space dilation, the photon leaves and arrives simultaneously experiencing no time as well as traveling through no space. The space between becomes shorter and shorter as you approach C. A photons departure point is the same as its arrival point from the photons point of view

Have you tried Jesus Christ?

I discovered sound had a finite speed when I was 6 years old. I remember watching some dump trucks at a construction site dumping rock. I was about 1/4 of a mile away. I noticed after the truck dumped it load and started lowering the truck bed the rear door would slam against the back of the truck and it took a second for me to hear the bang created by it. I was fascinated by it and sat there for a while to keep hearing it.
I saw a man hammering a fence post into the ground at the other side of a field. Over and over again, the sound of him hitting the post reached me at the same time as the sight of his hammer reaching the top of his next swing. It looked weird.
@@sweginator1084 Knowing the speed of sound at ground level, by counting the seconds between lightning and thunder we can tell how far away the storm is.
That's the best lesson on light speed I've ever seen! It's the first time I've felt like maybe I kinda sorta understand it! So, I've gone from being totally whacked out confused by it to now kinda sorta understanding it... a giant leap! Thanks so much!

Steven Hawking, Micio Kaku and many other snobby scam artists pretending to be theoretical physicists, just played it safe when they chose to be experts on intellectual esoterism, that is not going to be testable, that have no predictions that could be derived from the unprovable "teories". So they can pretend to know something by imagining an elaborate intellectual construct they call teory. Even tho almost no one claims to understand it. And since they can't prove it, no one can disprove it. Handy.
Reminds me of that limerick Data cracks in TNG s1e3 😄 "There was a young lady from Venus Whose body was shaped like a penis First contact was made And the crew were dismayed When she told them her species and genus"
Actually what you need is someone whose eaten several pots of Texas 5 Alarm chili with extra onions. Very soon he will make a blast that will start you flying faster than light. You have to, to get ahead of the stink.
I've heard that, to measure the speed of light, you can't have something at the other end sending a message when light is detected, because that message also travels at the speed of light. This means that you actually measure how fast light travels from point A to point B, then back to point A, and you have to divide by two and assume that there are no changes in speed. It is possible that light travels instantly from point A to point B, then takes the rest of the time from point B to point A, and we wouldn't be able to know that. I can't remember where I read that, so if I'm wrong, don't hesitate to correct me.
Yes. You saw it on a Veritasium's video possibly. But that is not really a scientifical answer. Like someone answered in the video, the reason we know that speed of light is constant in all directions is not because we measured it, but because we can obtain a wave equation from Maxwell equations that describes electromagnetic waves (light) with a constant speed. This constant speed is a function of other constants, we have the speed of light as a function, we dont necessarily need to verify with an experiment and achieve anything.
@@KostasTsakalidis Thanks for the precision. I think you're right, it must have been from Veritasium. Ngl, this is a bit too advanced for me, so even with your explanation, I struggle to understand the principle, but that's alright.
@@KostasTsakalidis "we dont necessarily need to verify with an experiment and achieve anything" more heretical words have never been said. Experiment is everything.
@@snakeoo7ca We don't know if anything exists. Let's take your example with gravity: We don't have quantum theory for gravity. There are some indications that it might not be a quantum field at all, and that it might be an emergent property. Understanding the nature of the gravity, including whether it actually exists or is it just an illusion created by more fundamental interactions, is at the forefront of physics and must be tested with experiments, just like anything else. We need as many experiments as we can, and we should constantly try to invent new ones, to increase our confidence level in how things actually work. Scholars forgetting that the ultimate judge is an experiment and getting lost in logic/math is a trend that has been going since before physics existed, and has prevented many great minds from realizing their potential. Going back to the one-way speed of light, here have been many attempts at constructing an experiment for measuring it. This alone proves that it's a problem people take seriously, rightfully so I must say.

“Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws. The Hingefreel people of Arkintoofle Minor did try to build spaceships that were powered by bad news but they didn't work particularly well and were so extremely unwelcome whenever they arrived anywhere that there wasn't really any point in being there.” ― Douglas Adams
@@blakdragon2202, maybe you're looking at the problem wrong, if two objects that are both traveling close the speed of light and are traveling in opposite directions compare their speed with one another what would be the result?
@@blakdragon2202first, it's not the universe that's moving, it's expanding. second the question is, is the universe expanding quicker then the speed of light.
I swear. The day wormholes are discovered is when you'll see Tesla and Einstein on the other side sipping mai tais in Cancun shouting, "WHAT TOOK YOU SO LONG?!"
i mean... the simple solution is just change the speed of light :P or instead of you needing to move you could just have something else move you which could also allow it (warp, Slipspace, Hyperspace, wormhole) :P
Einstein never predicted the existence of wormholes, he just stated that - mathematically - it's not impossible. That's a very different thing. For wormholes to exist, you need something that has never been discovered yet, and is unlikely to exist (at least in great numbers and / or nearby): anti - gravity. Without that, wormholes will never be more than "not impossible". For the rest a very informative and good video!
Totally agree. mph is practically as bad as measuring in cubits when it comes to establishing wavelengths in free space. velocity 300,000,000 mps (approx) in free space / frequency in Hz = wavelength in metres.
And he got it completely wrong. The speed of c in MPH is 11,160,000. He was nowhere near! EDIT: Sorry guys, my math is off. I did 186,000 miles per second x60. This actually gives you the speed per minutes! Turns out he is right and I'm a dumbass who obviously hasn't had enough sleep
@@Lord_Skeptic I know, I was rounding. When you say 186 thousand miles per second, no one cares about the rest, since it takes a while just to say this.
@@Lord_Skeptic Which rolls off the tongue far easier and is close enough for a YT comment. You could say that everyone quotes Pi wrong, since no one has the time to mention the infinite digits that precede the first few decimals.
If you could send a message faster than light, and the receiver of the message was moving, then time dilation could be bigger than the time the message spent in transit. So it would be possible to receive a reply before you even sent the message. This is known as Tolman's Paradox, and it's why most physicists are highly skeptical about any kind of FTL hacks, including wormholes.
Time dilation is somewhat of a fairytale think about it we made up time to more effectively manage our days even simple things like second minutes days years moths are made up to fit the planet we live on time is something the universe doesnt care about add all
Wouldn't that mean that we just need mass to energy converters? Then we could "beam" to precise locations anything and reassemble it exactly as it was nearly instantly.
Majesty:: Mercury can. !!! Majesty:: if we can measure light speed in A one meters above. And we can measure the the light mercury content in this one meter light. We will know the distance between earth and Mars and other planets 🪐 to. The speed of Mercury inseid the Leizer light !! It’s not only change the color Leizer light in one second it s olso already moving inseid the Leizer light. Faster then Leizer light. 🤔 Thank you Brah. Prof Rida Ishmael. 🙏
So to negate Tolman's paradox would require the FTL message to 'deflect' the right amount into the future of a time dilating receiver to resolve the paradox. Interesting possible new 'field' effect-- the Tolman anti-dilation Field if you like?
Damn that makes so much sense! Or maybe the claim is nothing is faster than light, because it couldn`t be proven, because it couldn`t be seen doing that? :D :D :D

5. Inter-dimensional crossing, making the craft bend the speed of light around it and fall into another position in space and time. Matter can only travel as fast as light because light builds matter, by dematerialising the energy and rematerialising, you can change timelines and bypass “speed” itself.

Actually, mass doesn't change with velocity - rather, momentum, p, in special relativity, has a non-proportional dependence on velocity. The fallacy that mass depends on velocity, as m = γm₀ , where γ = 1/√(1-[v/c]²) arises from the false assignment of the "γ" factor in the momentum formula p = γm₀v to "m," when in fact, it belongs with "v;" that is, it governs the way momentum (not mass) depends on velocity. It is also refuted by the different way kinetic energy, T, depends on velocity: T = (γ-1)m₀c² ≠ ½γm₀v² It is these velocity dependences that mathematically limit |v| < c for any object with mass.

Theoretically we could build an Alcubierre drive that would form a wave of space time behind the craft that would be able to propel the craft faster than the speed of light without breaking laws of physics because it moves the space around the craft instead of the craft itself. However this would require negative matter which has obviously not been discovered in nature or created in a lab.
Shout out to my boy Miguel Alcubiere for taking the time to design a contracted/expanding bubble of space time just to theorically prove that the starship Enterprise could in fact, travel faster than light
The reason that light can travel at 186,000 miles per second is that light has no mass. It is impossible for anything with mass to travel at the speed of light. The greater the speed the more mass it has and near the speed of light an object would have so much mass that the force to go at the speed of light would be impossible to attain.
If we want to find and use every loophole in the Theory of Relativity, that's easily achieved. Our mistake has been to use physicists for studying the issue, when the guys we need are tax lawyers. Those loophole experts will have it figured out in no time. Of course, they're damn expensive...
I'll tell ya, I started out pursuing law, but they turned and pursued me so I said screw that, but yes, you hit it on the head, it is indeed the loopholes, the, "leaps of faith," that makes Einstein's special theory of relativity bunk. Light is not the speed limit, it is not the most powerful force in the universe, and the term metaphysical is like a rag doll we should all cuddle with each night and protect it as long as our silly minds can because when we can see what we cannot see at this time, we will wish we were back in our cribs screaming because our diapers are giving us a rash.
@@vampG1 true and false. they actually haven't experienced any time passage. Only observers outside their frame of reference have. To US they are from the distant past, from a distant object. To the photon, it is everywhere at once and no time has passed between it being perceivable as coming from some star and some observer far away from that star perceiving it.
@@ethanmorgan2189 but what does that have to do with it? If you want you can go ahead and convert the units to the metric system.

Technically, the Mass Relays function by creating a mass-free "corridor" of space-time between each other. So, therefore, zero mass at acceleration, time's infinity equals zero. The laws of possibility with our current technology still stand.

So you would rather waste 18mins of your life by some guy with a fake mustache then listen to the real explanation that he never even gave? Strange how you even came to an understanding when he didnt even offer one. The truth is that you have to be light to travel at the speed of light, and the only things that can faster dont exist so technically nothing can go faster than the speed of light and exist at the same time. Not sure what classes fucked that up for you a million times, but this man is NOT the solution.

It’s been said that even though the speed of light is incredibly fast (approximately 186,000 miles per second), when it comes to the size of the universe and the distance between stars and galaxies, it’s also incredibly, painfully slow.
Yeah, of course. We will never see beyond a certain distance in the universe, because light has the speed limit. Unless we invent a worm hole. Which has been talked about and if I remember correctly, the calculations show it could be done. We just can't, yet.

its not even the thing ur talking which they are very good well put in but its the images and video quality its jaw dropping bro. just amazing hard work
I enjoy the idea of bending space to produce FTL travel. I've seen some interesting thing regarding a theoretical ship that through the manipulation of gravity would bend the space in front of and behind it. The most interesting factor is that the theory for the ship itself would have it not even moving, or moving very very slowly, from it's own frame of reference. Essentially this is the Star trek Hyperdrive and hyperspace. Although rather then there being some kind of sub-space that the ship travels through It would essentially be moving instantaneously between points in regular space. Or more accurately points in regular space would be manipulated by said ship so that it would appear to go from occupying one point to occupying another in an immeasurable amount of time. very cool stuff
Michael from Vsauce channel has an episode titled “ the speed of dark” which discusses an interesting situation regarding the speed of light and dark. He brings up a hypothetical in that if you shine an enormously bright light on the moon and put your hand in the way as to cast a shadow on the moon then move your hand quickly so the shadow moves from one edge to the other the shadow would cross the moon faster than light would.
0:58 actually from lights point of view, with time dilation taken into account, it is instantaneous. It only has a velocity according to an outside observer. Because, according to the photon itself, it took 0 seconds to go from it's start point to interacting with a piece of matter. Without a time reference, velocity cannot be calculated. So technically if you were to travel 1c, the travel time would be instant, but to someone else, your travel time would be however long light takes to travel that same distance. Also, because of the reference frame, you would be unable to calculate your own velocity.
Well instantaniouse would mean in this case that light would reach its destination instantanious. Therefore meaning that it cant have a speed, or source. because if it has a source there must be travel distance, and therfore there must be a constant speed, this speed might not be observable to you or me, but if you take the lights point of view there would actually be a travel time, givem theres enough distance. But if you mean it would reach light speed instantanious, you are right for light can not go faster or slower than light speed, therefore if these photons pop into existance time dialation would give the photon the time to get to light speed instantly. I hope you understand this. I hope i understand myself
@@Alexander27463 see, there's where scientists have trouble when it comes to light. Light does travel a distance but does so without time being a factor. (Relative to it's own state of reference) time dilation doesn't affect us while the light is traveling, therefore giving light a velocity. If you were able to put a saddle on a single photon and ride it from start to finish, (the point where you start measuring to the point you stop measuring) then from your perspective, the trip took 0 time. Although people watching you go by would see you traveling at the speed of light. It's also why the answer to the question "if you were in a car going light speed, what would happen if you turned on the headlights?" That light would still appear to travel away from you at the speed of light even though you are traveling that speed as well. Another good example of this (what I stated previous comment) is the Minkowski Diagram.
A Higgs boson walks into a church. "We don't allow Higgs bosons in here!" shouts the priest. "But without me, how can you have mass?" asks the particle.
The lightspeed limit only applies to the speed when moving through space. If you take into account universal expansion (which, itself, moves faster than light), light traveling in some directions travels much faster than _C_ which is why we have more "observable universe" than the speed of light would account for.
I think what you're describing is kinda like relative speed. Two objects traveling away from each other at the speed of light (if they could travel that fast) would appear to be moving away from each other faster than the speed of light as compared to an object travelling at the speed of light away from a stationary object. But neither object would actually be travelling faster than light.
@@ericmork630 No, I'm talking about a phenomenon well known to physicists, which is why "nothing can travel faster than the speed of light" is incorrect, and only used by a physicist as a sort of "shorthand" for the proper "nothing can travel _through space_ faster than the speed of light." Light traveling with the universe's expansion travels significantly faster than _C._ It doesn't just _appear_ to, or _from a perspective,_ it actually travels faster than the Speed of Light constant. Check out how long light has existed in our universe and compare that with the size of the 'visible universe' (which depends entirely on how far light has traveled) and you might start seeing (no pun intended) what I'm talking about.
@@muttleyjones2 No, you're just not grasping it. Expansion is not "space." Why is it, do you think, we can "see" further into the universe than light could possibly have traveled at _C?_ Do you think "expansion" travels at the speed of light or slower? If so, you are incorrect. What do you think RESHIFT is? This is not my opinion or my theory, it's commonly known PHYSICS.
I’m kind of glad that you said (with our current technology). I think the human race would be deluded to think that everything we know about the universe, the speed of light, the speed of sound and so on is the only way things can and do work. Who’s to say that an alien race that turned up tomorrow and after laughing at us for a bit, then went on to explain a whole different concept of speed and FTL travel….
If they showed up theyd look young but be so old compared to everyone back in their land. If they took some of us back prisoners it'd be a totally different planet for them hundreds or thousands of years into the future and their mission and the mission plan wouldve ended/failed/long forgotten.
We don’t actually know the one way speed of light, because of the two clock synchronization issue. We simply reflect the light beam and average the original and return trip, meaning we can use one clock. We assume light travels at the same speed on both sections of the trip.
Great video! Not sure about the baby with Sonic, but Superman has some crazy physics breaking comic book super luminal ability, as he flew to Krypton (remains) and back in only five years. No idea how far away Krypton was but since it isn't the nearest star, more than a few lightyears.

What I always found fascinating was the time dilation. When a light particle is created from our vantage it can take thousands of years to escape the sun. Then about 8 and a half minutes to get to the earth and the back of your eye where it annihilates. But from the particles point of view due to time dilation it would be instantaneous. Thus creating and annihilating at the same time. Drawing out a null line. A distance crossed in zero time. This one little thing in relativity melted my brain.
That is because the only real constant in the universe is the one thing that we still do not truly understand. gravity. Time, and therefore, the speed of light is only truly relative to gravity.
One thing that always fascinated me about this concept is that, from the photon's point of view, it only exists for a timeless instant as a line connecting its creation point and its endpoint. This means that the endpoint of the light beam effectively exists as a beam that crosses time as well as space, since the endpoint is in the future of the creation point. It's mind-bending to wrap your head around.
It's all hypothetical, so, he is my interpretation. If light has life, it's processes would be effected environmentally. Thusly, to me, light would be capable of thinking and processing that information as fast as say, itself. So, upon that thought, it would be be 'being, living, etcetc' as we do. So around it (this living light) it would see everything frozen in time around it.....🐻
Really hoping for someone to carry this thought forward or backward for me. My brain hurts after fiction/factional thinking's🐻
Another way to think about it is space dilation, the photon leaves and arrives simultaneously experiencing no time as well as traveling through no space. The space between becomes shorter and shorter as you approach C. A photons departure point is the same as its arrival point from the photons point of view
@@slo3337 Indeed, no time, no distance - from the point of view of photon it never existed! :)

John stated (In the book so named):

2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the *light* of men.
5 And the light shineth in darkness; and the darkness comprehended it not.
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.

I discovered sound had a finite speed when I was 6 years old. I remember watching some dump trucks at a construction site dumping rock. I was about 1/4 of a mile away. I noticed after the truck dumped it load and started lowering the truck bed the rear door would slam against the back of the truck and it took a second for me to hear the bang created by it. I was fascinated by it and sat there for a while to keep hearing it.
I saw a man hammering a fence post into the ground at the other side of a field. Over and over again, the sound of him hitting the post reached me at the same time as the sight of his hammer reaching the top of his next swing. It looked weird.

Yes indeed.... Everything is assumed... "Let us assume"
I've heard that, to measure the speed of light, you can't have something at the other end sending a message when light is detected, because that message also travels at the speed of light. This means that you actually measure how fast light travels from point A to point B, then back to point A, and you have to divide by two and assume that there are no changes in speed. It is possible that light travels instantly from point A to point B, then takes the rest of the time from point B to point A, and we wouldn't be able to know that.
I can't remember where I read that, so if I'm wrong, don't hesitate to correct me.
Yes. You saw it on a Veritasium's video possibly. But that is not really a scientifical answer. Like someone answered in the video, the reason we know that speed of light is constant in all directions is not because we measured it, but because we can obtain a wave equation from Maxwell equations that describes electromagnetic waves (light) with a constant speed. This constant speed is a function of other constants, we have the speed of light as a function, we dont necessarily need to verify with an experiment and achieve anything.
@@KostasTsakalidis Thanks for the precision. I think you're right, it must have been from Veritasium. Ngl, this is a bit too advanced for me, so even with your explanation, I struggle to understand the principle, but that's alright.

@@snakeoo7ca We don't know if anything exists. Let's take your example with gravity:
We don't have quantum theory for gravity. There are some indications that it might not be a quantum field at all, and that it might be an emergent property. Understanding the nature of the gravity, including whether it actually exists or is it just an illusion created by more fundamental interactions, is at the forefront of physics and must be tested with experiments, just like anything else.
We need as many experiments as we can, and we should constantly try to invent new ones, to increase our confidence level in how things actually work. Scholars forgetting that the ultimate judge is an experiment and getting lost in logic/math is a trend that has been going since before physics existed, and has prevented many great minds from realizing their potential.
Going back to the one-way speed of light, here have been many attempts at constructing an experiment for measuring it. This alone proves that it's a problem people take seriously, rightfully so I must say.

Einstein never predicted the existence of wormholes, he just stated that - mathematically - it's not impossible. That's a very different thing. For wormholes to exist, you need something that has never been discovered yet, and is unlikely to exist (at least in great numbers and / or nearby): anti - gravity.
Without that, wormholes will never be more than "not impossible".
For the rest a very informative and good video!
I'd love to see anti-gravity and wormholes in an accurate computer simulation based on the classic model. Would be very interesting.

Measuring the speed of light in MPH - BLASPHEMY!
Totally agree. mph is practically as bad as measuring in cubits when it comes to establishing wavelengths in free space. velocity 300,000,000 mps (approx) in free space / frequency in Hz = wavelength in metres.

If you could send a message faster than light, and the receiver of the message was moving, then time dilation could be bigger than the time the message spent in transit. So it would be possible to receive a reply before you even sent the message. This is known as Tolman's Paradox, and it's why most physicists are highly skeptical about any kind of FTL hacks, including wormholes.
Time dilation is somewhat of a fairytale think about it we made up time to more effectively manage our days even simple things like second minutes days years moths are made up to fit the planet we live on time is something the universe doesnt care about add all
Wouldn't that mean that we just need mass to energy converters? Then we could "beam" to precise locations anything and reassemble it exactly as it was nearly instantly.

@@averagelifeenjoyer I have. But I've haven't seen anything that suggests we're anywhere close to achieving negative energy density.
Actually, mass doesn't change with velocity - rather, momentum, p, in special relativity, has a non-proportional dependence on velocity. The fallacy that mass depends on velocity, as
m = γm₀ , where γ = 1/√(1-[v/c]²)
arises from the false assignment of the "γ" factor in the momentum formula
p = γm₀v
to "m," when in fact, it belongs with "v;" that is, it governs the way momentum (not mass) depends on velocity.
It is also refuted by the different way kinetic energy, T, depends on velocity:
T = (γ-1)m₀c² ≠ ½γm₀v²
It is these velocity dependences that mathematically limit |v| < c for any object with mass.

@nicky Fogg since when most the world uses the metric system
@@ethanmorgan2189 but what does that have to do with it? If you want you can go ahead and convert the units to the metric system. Also I didn't know that science was limited to what the majority deems valid by practice, whatever works in science works and it makes no difference what anyone else chooses to do or what their opinion is.
@nicky Fogg it's not government idea it's a standard accurately defined measurement.
Used all over the word.
@nicky Fogg well define a mile or an inch for that matter how do you create a scale for that without using cm, let's not even start about conversions,

Technically, the Mass Relays function by creating a mass-free "corridor" of space-time between each other. So, therefore, zero mass at acceleration, time's infinity equals zero. The laws of possibility with our current technology still stand.

@Carl Hopf What are you on about, they are talking about a video game shut up about your politics
@@nymbattheeternal1279 But the mass relays are only used to travel great distances in the galaxy, when traveling from one solar system to a neighboring system, they use FTL, right?

Don't worry, light still travels at the speed of light. It's jut space is flowing into black holes at the speed of light so light can't get away.
Bet Goku could
@@bundleization You are correct, Goku has been able to travel at superluminal speeds since saiyan saga so black holes are no problem for him.
But dose we actually *know* the speed of light?
Does that make black holes God's own _highway patrol_?
Be well.
i discovered your channel today and i higly appreciate the fact, that you are talking clean,calm and slow enough to follow. I am german and apart from the fact, that this video is really well made i was able to understand it.
This is something rare these days so thank you for that.
Nice video, 42. One suggestion: When talking about units, if you go imperial please put somewhere on screen the equivalent in metric units. And again thank you for the video, good one!
7:51 the image that had haunted my mind was not needed. I was listening to the video in the background rather than actually watching so I wasn'texpectingit in the least. This was otherwise one of the best video I've listened to so far perfectly explaining such things I wouldn't have been able to comprehend if i was simply sitting in a classroom being told something I'd already heard millions of times before taught in school.
So you would rather waste 18mins of your life by some guy with a fake mustache then listen to the real explanation that he never even gave? Strange how you even came to an understanding when he didnt even offer one. The truth is that you have to be light to travel at the speed of light, and the only things that can faster dont exist so technically nothing can go faster than the speed of light and exist at the same time. Not sure what classes fucked that up for you a million times, but this man is NOT the solution.

It’s been said that even though the speed of light is incredibly fast (approximately 186,000 miles per second), when it comes to the size of the universe and the distance between stars and galaxies, it’s also incredibly, painfully slow.
Yeah, of course.
We will never see beyond a certain distance in the universe, because light has the speed limit.
Unless we invent a worm hole. Which has been talked about and if I remember correctly, the calculations show it could be done. We just can't, yet.
So true have u ever watched the video we are incredibly small if not I recommended
@@odonnelly46 The scary part is the separation of stars. in the distant future, with the current expansion there will no longer be stars in the sky.
Been watching you for a couple years now. First time iv taken the time to read your channel name. This entire time iv thought you say "hello forty two here" 🤣😅 love your videos keep em coming cousin 👍

I was just about to comment that 😂
͔ 😂
I can approve
Replying for title updates
mmh i wouldnt say we can't travel faster than the speed of light because right now anything is possible, humans are too stupid to understand anything about space nvm their own planet so it's all theories on almost everything we know thus far.

its not even the thing ur talking which they are very good well put in but its the images and video quality its jaw dropping bro. just amazing hard work
I enjoy the idea of bending space to produce FTL travel. I've seen some interesting thing regarding a theoretical ship that through the manipulation of gravity would bend the space in front of and behind it. The most interesting factor is that the theory for the ship itself would have it not even moving, or moving very very slowly, from it's own frame of reference. Essentially this is the Star trek Hyperdrive and hyperspace. Although rather then there being some kind of sub-space that the ship travels through It would essentially be moving instantaneously between points in regular space. Or more accurately points in regular space would be manipulated by said ship so that it would appear to go from occupying one point to occupying another in an immeasurable amount of time. very cool stuff
Sounds like the planet express ship haha
Yup. This is referred to as the "Alcubierre Drive."
The ammount of pseudo-science in people who think you can bend space.
@@eu29lex16 NASA was recently able to prove it atleast on a microscopic scale
They accidentaly made the first warp bubble
Michael from Vsauce channel has an episode titled “ the speed of dark” which discusses an interesting situation regarding the speed of light and dark.
He brings up a hypothetical in that if you shine an enormously bright light on the moon and put your hand in the way as to cast a shadow on the moon then move your hand quickly so the shadow moves from one edge to the other the shadow would cross the moon faster than light would.
Stop.......my brain can’t handle it:/
That sounds so cool tho
well not really though
That is because "the dark" here is the absence of something rather than something, and therefore nothing is moving at all.
@@korpen2858 yes.
Korpen yeah but information would be moving faster than light, not sure if that’s what the end goal was tho I haven’t watched the video
Thanks for the quality content as always. I just want to point out that at 8:06 it is 0.0006 times the speed of light or 0.06% the speed of light.
01:44 that experiment also immediately shows us that light is faster than sound ;)
“And the game assets in No Mans Sky”
Funny, the update for variation just came out
0:58 actually from lights point of view, with time dilation taken into account, it is instantaneous. It only has a velocity according to an outside observer. Because, according to the photon itself, it took 0 seconds to go from it's start point to interacting with a piece of matter. Without a time reference, velocity cannot be calculated. So technically if you were to travel 1c, the travel time would be instant, but to someone else, your travel time would be however long light takes to travel that same distance. Also, because of the reference frame, you would be unable to calculate your own velocity.
big brain
yea tbh this video was not very comprehensive or detailed it was a pretty basic overview but still a g vid
This is very true
Well instantaniouse would mean in this case that light would reach its destination instantanious.
Therefore meaning that it cant have a speed, or source. because if it has a source there must be travel distance, and therfore there must be a constant speed, this speed might not be observable to you or me, but if you take the lights point of view there would actually be a travel time, givem theres enough distance.
But if you mean it would reach light speed instantanious, you are right for light can not go faster or slower than light speed, therefore if these photons pop into existance time dialation would give the photon the time to get to light speed instantly.
I hope you understand this.
I hope i understand myself
@@Alexander27463 see, there's where scientists have trouble when it comes to light. Light does travel a distance but does so without time being a factor. (Relative to it's own state of reference) time dilation doesn't affect us while the light is traveling, therefore giving light a velocity. If you were able to put a saddle on a single photon and ride it from start to finish, (the point where you start measuring to the point you stop measuring) then from your perspective, the trip took 0 time. Although people watching you go by would see you traveling at the speed of light. It's also why the answer to the question "if you were in a car going light speed, what would happen if you turned on the headlights?" That light would still appear to travel away from you at the speed of light even though you are traveling that speed as well. Another good example of this (what I stated previous comment) is the Minkowski Diagram.
he made a no mans sky reference and i understood it i feel so accomplished
He really knows his target audience.
We cant in normal space, but we could in hyperspace.

The lightspeed limit only applies to the speed when moving through space. If you take into account universal expansion (which, itself, moves faster than light), light traveling in some directions travels much faster than _C_ which is why we have more "observable universe" than the speed of light would account for.
I think what you're describing is kinda like relative speed. Two objects traveling away from each other at the speed of light (if they could travel that fast) would appear to be moving away from each other faster than the speed of light as compared to an object travelling at the speed of light away from a stationary object. But neither object would actually be travelling faster than light.
@@ericmork630 No, I'm talking about a phenomenon well known to physicists, which is why "nothing can travel faster than the speed of light" is incorrect, and only used by a physicist as a sort of "shorthand" for the proper "nothing can travel _through space_ faster than the speed of light."
Light traveling with the universe's expansion travels significantly faster than _C._ It doesn't just _appear_ to, or _from a perspective,_ it actually travels faster than the Speed of Light constant.
Check out how long light has existed in our universe and compare that with the size of the 'visible universe' (which depends entirely on how far light has traveled) and you might start seeing (no pun intended) what I'm talking about.
Where do you think light travels if it isn't always traveling through space? Saying c only applies when moving through space is redundant.
@@muttleyjones2 No, you're just not grasping it. Expansion is not "space." Why is it, do you think, we can "see" further into the universe than light could possibly have traveled at _C?_ Do you think "expansion" travels at the speed of light or slower? If so, you are incorrect. What do you think RESHIFT is?
This is not my opinion or my theory, it's commonly known PHYSICS.
@@Heath.houston my god what a dummy, if its not space what is it? lol
I’m kind of glad that you said (with our current technology). I think the human race would be deluded to think that everything we know about the universe, the speed of light, the speed of sound and so on is the only way things can and do work.
Who’s to say that an alien race that turned up tomorrow and after laughing at us for a bit, then went on to explain a whole different concept of speed and FTL travel….
If they showed up theyd look young but be so old compared to everyone back in their land. If they took some of us back prisoners it'd be a totally different planet for them hundreds or thousands of years into the future and their mission and the mission plan wouldve ended/failed/long forgotten.
It would also probably be through a wormhole or blackhole.
We don’t actually know the one way speed of light, because of the two clock synchronization issue. We simply reflect the light beam and average the original and return trip, meaning we can use one clock. We assume light travels at the same speed on both sections of the trip.
How about folding the fabric of space theory?
