“The only thing that travels faster than light, is bad news.” - British Author Douglas Adams.
Gossip is faster.
Though ultimately rather minute compared to everything else, the first thing that sprung to mind with the spinning tether thing is that if you start extending carbon nanotubes out, no matter how light they are, the whole apparatus will spin more slowly due to the conservation of angular momentum.
Yes! And you would need to keep adding more power to keep the revs up. Which would get harder and harder as the ends of the tether approached C and their inertia increased.

When I was in 6th grade, I had a *science* teacher claim that it should be impossible for a stick to move faster at one end than at the other because the stick was a solid object and solid objects can't move at more than one speed. That always bothered me because I knew it had to be wrong, even then, but could never quite conceptualize why. Your "long stick across the moon" - explaining that the atoms that make up the stick have to bump into each other to move the whole - you just crystalized the answer for me. 43 years later. Thank you!💌
The entire concept of a rigid body is an approximation. By that logic, rip a paper into two pieces. Boom, a solid object whose one part moves at a different speed than its other part.

But there is always “Faster than the Speed of Love” by Brian Griffin....
Question: remember the episode where you made the car wind sail that would go faster than the speed of the wind? Well can’t we just do that with light?
That wouldn't work, because there is a fundamental difference: -light has no mass- photons have no rest mass. An object with a mass would need an infinite amount of energy to reach the speed of light, meaning the speed of light itself isn't attainable for matter. However, a similar system with a solar sail theoretically permits to approach very close to the speed of light. It would take an incredibly long time, given the explanation of Daniel Lupton below.
@@raycharlz4937 Well light has energy and therefore mass. A photon has no rest mass, but they all have energy and momentum. A solar sail takes advantage of that momentum. The real problem is that at relativistic speeds, any light hitting the back of the sail would be red-shifted to the point where it has no energy from the perspective of the vehicle. If you did reach or exceed the speed of light, there wouldn't be any photons that could catch up to "push" the car.
@@daniel.lupton I agree, light has energy, therefore mass. And the fact that it would have almost no energy to give because of the red shift is correct too. But the core part of my explanation still stands, an object with mass can't ever reach the speed of light, it can only approach it because it would need an infinite amount of energy. Then the solar sail can't go faster than light even if we found a way to continue to supply it with energy. I updated my other comment to take yours into account.
the major problem with reaching the speed of light is *Mass*.
Well wind particles are air... Air has mass even if a little it adds up. Light however has no mass. That's why photons only travel at light speed. The energy is dividing by zero and reaching infinity which is the amount of energy required to reach light speed
Honestly sad, even if we moved at the speed of light, exploring the universe is pretty much impossible. Due to the distance between those objects.
Its only bad for the people left behind as the closer you get to the speed of light the less time that passes for you relative to the universe
If your travelling at the speed of light, time for you travels slower. So if you were going at the speed of light, time would completely stop for you, so it would take literally no time to go to the place you were going to, but for everyone else at Earth, they would age a year for every light year you travel. So if you travelled 1million light years, in the traveller's perspective, no time has passed, but to people on Earth, 1million years has passed.

Thanks for the materials science point of view of WHY there's no bleeping way to make anything go FTL. The explanation of the atoms bonding to create materials and the bond interaction provides a tombstone for every imaginary experiment.
I've always hated the use of faster than light travel in movies because the fundamental particles that make up matter cannot travel faster than light so why would a giant cluster of them be able to. I don't mind when they talk about travelling through wormholes to cut corners (like in thor ragnarok when they travel through the einstein-rosen bridge) but ftl travel is nonsense and I hate seeing it in movies nearly as much as I hate when movies include time travel
I think that the fact that mass (or inertia as you mention) approaches infinity as the speed goes approaches the speed of light IS the ultimate blocker to anything moving at the speed of light but the propagation speed of the movement down that long rod is a good point too..

Accurate.
Man I pity the man who gave that innocent idea to Derek it was just a naive idea but Derek meant it as a professional one
@Veritasium I also want to add that when an object is rotating in space with a speed close to the speed of light has a conserved angular momentum proportionate to the mass, speed, and radius from the center of mass at that speed. The problem is that the longer the carbon nanotubes become the larger the radius towards that center of mass. Since the momentum is conserved then as r goes up velocity has to come down. So basically you would come very close to a nonrotating body at some point. Could be wrong tho...
Nope that’s absolutely right as lim tends to infinity w hits near 0 basically meaning it’s not rotating anymore/ moving realllly slow

Alain Martel you vs University professor
what if you build a car that can go 99% the speed if light and then add stripes which will add 2% to the speed it will then be going faster then the speed of light
Taking relativity space and time dilation into account, 99% + 2% = 99.0390% Space and time dilation always results in velocity less than c no matter what numbers you apply.
What if you keep adding stripes witch will keep on increasing the speed, and eventually it will be 101%.
ian kirwan You get closer and closer to c, but never reach it. 99%c+99%c = 99.9949%c 99%c+99%c+99%c = 99.99997437%c
what if you turned the lights off and you could sneak past light when its not looking...and then add stripes.
+ian kirwan The only valuable thing this is that speed of light is CONSTANT. Which means no matter how fast you're moving, speed of light relative to any system will be c.
If negative mass was a possibility then with super dense negative mass near slightly less dense positive mass you would theoretically be able to bend space time on a way to allow speeds faster than light, because the speed of light only applies to flat space time, not warped.
Ah the Warp Drive
The speed of light doesn't "only apply to flat spacetime". General relativity is essentially all about curved spacetime and holds c in the same regard as special relativity. I think what you're suggesting is the Alcubierre drive which theoretically works by manipulating the space around it. There's good reason to believe it's not possible to construct such a device.
If you have a laser than multiple timers set up on its path, you set the timers to wait to start counting until all timers have received the signal without needing to talk to each other by syncing with the already perceived time of the speed of light, then have the laser go along the line and the timers stop as soon as the laser hits the timer repeat in different directions if you are getting different results than the direction has an effect on the speed of light if the results are to the point exactly the same than you have light travelling at one speed in all directions
1400 years from now: "lol this idiots thought that light was the ultimate speed limit" *wooshes away at the speed of 6.23 galaxies per universal standart time unit
Lmao
Still potentially possible. Any particle with mass cant possibly go faster than the speed of light, for reasons described in the video. However, assuming you had infinite energy, you could theoretically somehow bend spacetime to pull yourself along it in a way that reaches some destination in a smaller amount of time than it would take light to travel there, thus effectively travelling faster than the speed of light without actually moving at all in the traditional sense. Iirc, we'd need more energy than is available in the observable universe for this.. but maybe with more efficient batteries, who knows haha :P

I was hoping this video would be about manipulating space-time or leaving it entirely, because if the speed of light can effectively be exceeded ("effectively" being the key word there), those seem to be the only options we've got. Far-fetched? Yeah, but maybe not flatly impossible.
This was the best graphic description of this experiment.
If you build a wall around the speed of light, surely that would stop the light from go any further and thus we can all move freely in a democratic manner faster than speed of light.
Or better yet, force the light to go faster!
The Flash disliked this video

That's because the speed force comes from a originated from another dimension. When expressed is this dimension faster than light travel is possible but only relatively.
Johan Jacobs you realize this was a joke, right?
2:10 also just like a bailerina by extending its arms it would spin slower.
I would like to ask a question. Why are we assuming that there is a cap on the potential speed of protons or of anything else? Just because that's the speed we've been able to measure them move at, does not determine the ability for them to move faster. It's only what we've been able to measure. This is why I believe the ability to move faster could still be there.
I haven't studied relativity, and hardly any Newtonian physics, so take this with a grain of salt. But here's my understanding: The speed of light in a vacuum is exactly the same for all frames of reference. A car driving at a hundred million mph sees light move at the same speed as a stationary observer does: the speed of light. The light doesn't move at the expected "speed of light plus 100 million mph" because of time dilation. Time dilates such that anything that *would* be moving faster than the speed of light (were reference frames composed using simple sums) moves less than or equal to the speed of light. Now, all this assumes that Einstein's equations for relativity are accurate, and so far we haven't found any disproofs for that. (I might be completely wrong here, but it's something along those lines: the speed of light shows up in the equations of relativity in such a way that moving faster than that speed is impossible)

Kids are dumb. Let me share a story with you. I was 13 or 14 and the history teacher came to the class and she said "you guys are becoming old enough to get informed about politics. You should read about it, talk about it with other people, exchange ideas and form your opinion on things and so on". A kid responded "yeah, but i don't want to. I'm not even old enough to be able to vote in an election, why should I care?" I couldn't hold myself (and i disliked that kid) then I raised my hand and said on spot "well, you are also not old enough to have a driver's license, yet you spend the whole time here at school talking about cars and so on. Forming a political opinion matters to everyone, the earlier the better" I felt embarrassed, the whole class looked at me in the same second. The teacher raised her eyebrows and chenged the subject of the conversation. The kid didn't argue with me later on, but i don't remember having lots of conversations with him since that day

5:00 So the moment you almost exceed the speed of light, the entire thing will...just dissolve into its individual particles.
Rata Touille Yes, assuming of course that you have infinte energy and time to accelerate it to that speed.
No, actually. Nothing in the machine is moving faster than the speed of light relative to closest thing it has to interact with. Therefore the machine would hold together if we assume the material it's made of has infinite tensile strength.
I'm afraid the video's EM binding explanation is incorrect. The atoms are bound by photon-exchange at the tip where the _local_ value of c in that reference frame remains the same. I'm frankly astonished that someone with a doctorate in educational physics has missed a fundamental tenet of Einstein's: c is a constant in all reference-frames. There is a slight complication in that the motion is non-linear and therefore requires a slight GR tweak, but the instantaneous velocity may be taken as 'linear' at such a long distance. The spinning wire paradox is resolved by the ordinary fact that not enough energy can be imparted to the tip for its velocity to equal c. The question, 'what would happen then?' isn't answered. The wire would simply start to wrap around the rotor until it was fully wrapped around. Conservation of angular momentum would then dictate the whole thing would spin up at a ridiculous rpm.
I love you channel. I've found it quite fascinating. Now, what about the idea of creating warp bubbles as it was first proposed in 1994 by the Mexican physicist Miguel Alcubierre? Would it be possible for you to post a video about that?
I imagine the force holding together particles is the speed of light, relative to the particles. So if, in an imagined scenario where a particle is traveling at c+1, to the electromagnetic forces its really that the particles are stationary and the entire universe is traveling around the particles instead.
put your semi truck in reverse and that should do it.
Backup a jet while it's on the ground over a can of Red Bull.
You're winner!
You might want to look into a whip, because the tip tries to move at infinite speed. It doesn’t obviously, because of the granularity of the material and the limits of the material’s strength, and if it ever got close for the reasons you discuss in this video. But a gentle arm motion can easily make the tip break the speed of sound.
The last point is far and away the most elegant explanation of why something we build can't go faster than light.
The light speed can be theoretically crossed, by using a source of energy, which is in massive quantities and Doesn't need apparatus. I am talking about, neutron stars. They have gravitional force at ridiculous levels. The huge constant acceleration will allow an object to maintain its speed, as it becomes tougher to accelerate further. Black holes are a bad idea because they have lots of debris in their event horizon, which can destroy the object.
move faster than light: go in a windowless enclosed room with a tight door. next, turn off the lights and run in circles
wrong person..
😂
Don't read me k the speed of the light particles themselves stay the same and when the light gets turned off the materials around it absorb all the light. By running in circles you are simply making yourself look like a fool. The light doesn't slow down it just becomes more difficult to see due to the decrease in photons.
ScienceIsCool what if nobody else is in the room, then he is not making himself look like a fool ( doesn't mean he is not)

4:50 the moment where your mind just blows.
Ok. I have read "To Sleep In A Sea Of Stars" by Christopher Paolini. Amazing book 😀 Well, obviously it's a sci fi book, so not actual science. However, Paolini has always been great at doing research on topics before writing about them. Paolini has in his book created a FTL drive for his ships (Faster Than Light). As I have understood the whole thing (as english is not my native language) the FTL drive creates a "bubble" around the ship (Paolini calls it a Markov bubble). Then the ship remains stationary within that bubble, but the space in front of the bubble is compressed and then behind the bubble the space is again expanded. So the ship itself remains stationary, while moving through space. I have heard thise theories mentioned elsewhere as well, so I imagine that Paolini has too. Now, aside from the fact that we don't have the technology or any way of producing the energy needed for such thing, is it theoretically possible? At the end of the book, Paolini has even made up some science papers explaining how it all works, but that went somewhat over my head. I read along in the book, while listening to it at the same time to improve my english.
I read the book as well and I think his "Markov Drives" were heavily inspired by the Alcubierre Warp Drive, which is an actual theory out there. I'm no physicist so I wouldn't dare try to explain it here, but there are really fascinating videos about that topic here on youtube! My general understanding of the concept is though that the drive creates a bubble of space-time around the ship, so that space itself is warped (imagine it like a conveyor belt made out of space) while the ship stays stationary inside the bubble. But again, I'm no physicist, just someone who loves a good sci-fi book :)
in the spinning ship example, its pretty obvious that it wouldnt work right? like a figureskater holding her arms out, it slows her down

1:33 "You'd be lucky if the tip would move at all" I have trouble visualizing that. Would the pole break? Or curve/bend? What? I don't know :(
+Ma4zu6 I think he means the energy would get lost as heat as the movement traveled to the tip.
+Ma4zu6 What Ben said and... yes the pole would bend. A pole made of any materials will be flexible (if long enough). For example, concrete skyscraper actually sway in the wind. Not by a lot mind you (or the architect screwed up big time) but they do indeed sway (if tall enough).
+Ma4zu6 Assuming the pole would move, the speed of that is the speed of sound. So it's irrelevant.
+Razvan MIHAIU That isn't what they meant. They meant that the force traveling through the molecules of the stick travels at the speed of sound. Objects like sticks can be moved faster than the speed of sound, right? The tip could move much faster than sound. Just not light. The energy transfer to get to the tip would be wasted via heat, sound, etc., "Now this is a loss(y) process, so you'd be lucky if any of the energy made it to the tip at all". Over the course of the 450,000 miles of pole you would lose all of the energy you put into it due to waste, most likely. That's why the tip wouldn't move, not necessarily the bend (which possibly contributes).
+Ma4zu6 It's like when you lay a long rope on the floor and you pick up one end and whip it. You'll see a wave. The wave becomes smaller and smaller because it loses energy. It's about the same principle. The tip of the pole won't move.
3:06 Humm... so you're telling me there's a chance... got it
just use quantum entanglement and superposition and putting things back into superposition and by using the collapse of the wavefunction to transfer 1-bit while still being able to send more bits to send more bits and so on. eventually, you could transfer any arbitrarily large set of data across.
2:09 as the rod move out of the center the angular velocity will decrease... in order to maintain angular momentum... at some point the engine will not be able to sustain acceleration... (not to count any relativistic effect, which would make this effect stronger, as the rods ends will "increase" its mass)
6:28. A Reference to Dark Energy. That alone deserves a video.
also even simpler... as you release the tethers from the rotating space craft it would slow down its rotation, so you would have to keep putting energy in to keep their initial speed
I've watched this video multiple times, and its a very fascinating one at that but i did notice that name change, hopefully that will bring it some attention again :D
Here's a question that may help. I think we are asking the wrong questions. Y asking how to reach the speed of light. The first thing we should ask should be, how does light gain its speed? I mean photons have mass, and they seem to be able to reach this, "speed limit" so simply. What forces are making the photons move so quickly? And if we can find out what causes that force, maybe we could reach that speed as well.
Light doesn't "gain speed" exactly. It's created with its velocity, which never changes. The speed is determined partly by the "vacuum permittivity" and "vacuum permeability" constants. Google those for details. Photons don't have even a tiny smidgen of mass. (Photons are affected by a gravitational field because spacetime bends around massive objects, not because of gravity acting on a mass.)
Harsh Colby I have a theory that I am working on about photons and why we believe that the speed of light is the 'speed limit of the universe' A lot of the people of science will probably hate my theory, because it will involve breaking a widely accepted and cemented theory in the world of Science... I have to break the Theory of Relativity. Yes, I know people will initially wave it off because it essentially commits heresy to all forms of science, but I believe that I can provide enough supporting evidence to prove that my theory is correct in every way, shape and form. Would you mind telling me how *you* would react to someone trying to disprove the Theory of Relativity?
MicrowavableToast Photons are Energy. E=Mc2. There is no mass, Energy = Mass (non) x The speed of light. Energy = The speed of light. Energy can only travel at one speed - The speed of light. All radiation travels at this speed. Infra red, UV, Light, Gamma ect. it does not gain speed, it simply exists and is limited to said speed. The flaw in trying to reach this speed is that it is how fast light travels through SPACE. Now if we can compress and expand space, we can in theory get from A - B faster than light and no laws are broken.
The thing of it is... this kind of begs the question about the speed of light. Let me explain. A photon goes at the speed of light (obviously) and we say that a light particle has no mass. This HAS to be impossible. Gravity bends light. If photons truly had no mass, they would be unaffected by gravity, as in order for gravity to interact with an object, the other object requires mass of its own to make it have weight, which pulls it towards a gravitational pull. Black holes, therefore, would not be invisible. This leads to the idea that gravity stretches time. To an observer, on a sattelite for example, he will percieve movement on a gravitational body as being slowed. The reason? The photons are reaching the observer slower, making HIM perceive the actions as happening over a stretched period of time. If someone fell into a black hole, he would seem to move slower, and slower until he stops and disappears because the photons cannot bounce off of the man in the black hole and reach an observer. Spaghettification? Illusion. His legs are percieved as longer because tbe gravitational pull is stretching the amount of ti.e it takes for a photon reaches his eye, therefore it would look like his legs are stretching. We cannot see black holes because we only see light. We cannot perceive anything going faster! We used the theory of relativity on the fact that we cannot find anything faster than the speed of light. Argument for the speed of light being the speed limit is flawed, because we basically say the the speed of light is the fastest because the speed of light is the limit. Can you really calculate energy with the theory of relativity? What measirements of the speed of light are needed? Kilometers per hour? Meters per second? Whay about mass? Ounces? How do we measure energy? How do we measure the speed of energy? Photons are particles, right? Nothing could exist without mass, as a photon, as it exists, takes up space. If it takes up space, it has mass. We say that photons are particles that act like waves... I say no. They are particles. But yet it is similar to sound waves. You know how space is a huge vacuum? Well whe something like air escapes i to the void, it despirses evenly. Photons are dispersed evenly through the universe! With such minute mass it would react to the slightest movement, and follow it. We hear sound from the waves and vibrations caused by sou d vibrating through the air, we see light because photons act a similar way! The light spectrum is the type of waves that move the photons around! And we see them! Also, dark matter? Since it obviously exists, and we xant find it or measure it... it must be faster than light. If it were going faster than light, photons wouldnt have enough time to reflect properly off of it. Since we limited ourselves by making the theory of relativityour "laws of physics" says that nothing can go faster than light, making us blind to anything out there that defies our set law made by an old guy decades ago, We wont progress until we realize we may have outdated information that needs to be updated. And so many scientists are so stubborn as to this theory. They say "but that breaks the laws of physics!!1!11!!" Of course it breaks the laws of physics! The laws are broken because of a theory that begs the question. Ill type more later when im on a computer. I cant stand all the unrepairable typos im making on this kindle fire. Ill add more later. My theory is not finished yet, im just tired right now. Go ahead an make any comments you want on my theory so far. Im still working to improve it. See ya in a few days maybe.
MicrowavableToast gravity does not bend light, it bends the space light travels through thus giving the illusion it bends light. Black hold to this to such a point that the space light travels too leads back into the black hole in every direction thus light cannot escape it. Black holes ARE invisible, we only know they exist from the objects that orbit them.
A really enjoyable video, and I particularly like the stick waving at an image of the moon
Thank you for making physics so fun and explainable.
What if your on a spaceship going 99.999999 (etc)% the speed of light, and then started running forward. Wouldn’t you be traveling faster than the speed of light?
Sadly, no, but it's a really cool reason. From your perspective, you are sitting inside a spaceship that is going near the speed of light. Awesome! send me the schematics. You start running forward. You would make it from one end of the space ship to the other in what you perceive to be a normal amount of time, and you think that you're traveling faster than the speed of light. Eventually, you're journey ends, and you get off of the space ship to collect your nobel prize, only to find that hundreds of years have passed in what you thought was only a few minutes. See, the really weird thing about Einstein's theory of relativity is something called Time Dilation. The closer you get to the speed of light, the slower you move through time. So, from an outside perspective, the spaceship is moving at 99.9999999999% (10 decimal places) the speed of light, and you are moving at 99.99999999999% (11 decimal places) the speed of light inside it. You are still moving faster than it, but only by an infinitesimal amount. This phenomenon has actually been experimentally observed in satellites with hyper-accurate atomic clocks. As the satellite goes faster and faster, the clock starts ticking slower and slower. So, from the satellite's perspective, it is following newton's standard F = ma. But from the perspective of us mere earthlings, it follows the relativistic form of the equation.
No, the faster you go, the slower time goes for you
@@caseygravelle7672 That’s one of the most well structured and engaging KZhead comments I’ve ever read. Thanks for the insight, I always wanted to know that!
@@caseygravelle7672 So you lose your ability to run fast, got it.
In reference to what? If two people are going half the speed of light in opposite directions, one is going at speed of light for another. But that doesn't count
Can we get like- 5 more episodes on this exact topic? It's fun hearing you debunk faster than light theories.
On the space tether question, there is an important point which wasn't mentioned: the very act of extending both tethers would reduce the object's angular velocity, since each tether spreads mass farther from the center of mass - assuming there is no external force applied, it's moment of inertia must always remain constant.
It's not the moment of inertia that must remain constant, it is the angular momentum. Precisely what we are doing in that example, is changing the moment of inertia, and the angular velocity reduces as a consequence.
I admire the style - finding that long nose hair and dying it white! Well done sir! 😂 Jokes aside, great channel!

The speed of light squared..boom there you go
you cannot square a lim, illogical dude

When I start talking about bionicle lore my girlfriend leaves me faster than light
Speed of light: You can't defeat me! Speed of dark (Shadow): Hold my 🍺!
You must join the Dark Side. It's the only way to go faster
No, because its the same, if you shine laser to the moon, moving shadow is illusion.
@@O5MO your hand shadow is bigger if it is farther from the light source and the surface where your shadow will be cast. If you move one of your finger slightly its shadow will move in an inches or even meters in an instant. But shadow has no data it's only an occupied space in a lighted thing.
Darkness moves as fast as light
@@gorillageeks5645 -shut up dont ruin my propaganda!-
There are numerous theoretical creative ways to go "faster than light." Someday a machine/ship might be able to warp space around itself to appear to move faster than light. It might perhaps create different types of alternate dimensions with different or shortened lengths of space. There may be a way to influence or create a space where the laws of physics are different. It's virtually a sure bet, that there are particles and physics that we are not aware of yet. Most current math does make it look impossible, but the thing about math, is that it makes many things look impossible until someone proves they actually can be done! The historical record of this happening is extensive! Who knows, it may be possible some day, given enough time. I'm not saying it is possible, I'm just saying we can't say for certain.
The thing that makes us breaking the speed of light limit unlikely in my eyes is just the fact that traveling faster than light breaks causality, causes paradoxes and would result in whatever is traveling faster than light to move backwards in time rather than forwards, meaning they would arrive at a destination before they even departed. I don't see how it would ever be possible to develop FTL travel and overcome the issue of breaking causality and causing paradoxes.
@@StreakyBaconMan What you are saying of course sounds reasonable to me. Perhaps though by warping space a thing might go from point a to point b in less time , if point a and b are positioned closer together via warped space. It wouldn't create any causality or math issues per say. It does appear that space can be warped by large objects. Perhaps some day it will be no big deal for us to do it. I have no clear idea how it might be done though. I have my doubts about the negative mass and energy ideas. Recently Dr. Sony White from NASA, claimed to have found micro warp bubbles. Again I don't really know much about it though. I do have ion thrusters on my channel that lift their power supplies against Earth's gravity, and might go really fast in space with ultra small propellant tanks, or very high voltages, that I do know something about.
@@StreakyBaconMan Warping space behind the spaceship and actually moving through space are different so it possible. And while it does break causality, it doesn't always do it. As long as you don't mess with what you shouldn't mess with, nothing will break.

Fascinating. Cheers Derek!
Hi Veritasium team, hope this message reach reader. if you can accelerate constantly you can reach the speed of light and go even faster, the source for constance acceleration could be energy from stars or space itself as an energy source where you accelerate. that force on the other hand will be equal to normal gravitation for human. the energy source relative to us is much more bigger than we need for acceleration if using effectively. limits would be only acceleration force for the object and time of acceleration and then deceleration. thank you for your time
...but, seriously, I love everything you do.
You shold sit down with Brian Cox and.. just talk about stuff. I'd love to see that!!
that bugger though ...
Derek, there is a badword in the portuguese subtitle at 0:05, the correct subtitle at this second should be: "Einstein na teoria da relatividade especial, nada deve mover-se através do espaço mais rápido do que a luz"
KKKKKKKKKKKKKKKKKKKK
The speed of light as we know it is a value that has change from time to time... All we have is a estimation of the time it takes light to travel both direction of a path. So we don't know if the speed of light is constant or change during this measure. So... we can not tell if there is something faster or not... we simply don't know enough....
KZhead recommended me this in 2019 !! KZhead knows what I love better than anyone.💚💚
Artificial Intelligence knows what you love.
Today it recommended me too.

Aryan Mishra Fair. Alright, isn’t it also maybe just a little creepy though???
Same dude XD
moving faster than the speed of light changes time right and would be impossible to see, what if things are moving at the speed of light but we just dont see them. Like how you see more of a cars design if its going 60mph rarther than 200 mph
The closer a physical object gets to the speed of light, the more time would appear to slow down for that object from the perspective of an outside observer. So theoretically, an object moving the speed of light would appear to be motionless.
+Eric Reed But if the object if traveling above the speed of light, it would be un observable as it is static and does not move to humans
+xboxless: If we measure something to leave A and arrive at B in less time than it would take light to make the same trip, it's moving FTL. We'd be able to see it because it's not the object itself that we see, it's the light bouncing off it. (Think of light shining on a superluminal rock from the side, for example. There's no reason we couldn't observe it.) +Eric: Photons are moving the speed of light, yet do not appear motionless.
HarshColby We wouldnt see the object itsself surely as we only see the light that has bounced off it in the past
This is also true of objects moving slower than light. We see the light bounding of it, not the object itself. We see all objects in the past. How far in the past depends on how far away it is, not how fast it's moving.
Love the channel, a question if I may. Is the fact that elements exchange information with photons a proven fact or an accepted theory? In either case, I would like to know more. Cheers
Its a consequence of quantization in quantum mechanics, a photon is defined as the smallest quantity that makes up electromagnetic fields. So all information that is transferred by electromagnetic interaction (be it radiation, magnetic attraction, attraction and repulsion between charges) is governed by photons. Though it is not the only way to exchange information, for example in quantum gravity, you have gravitons that do the same thing just for gravitational fields. Gravitons are also assumed to be massless and always traveling with light speed. For most purposes though the electromagnetic way to transfer information is the most relevant because it is the only way that humans can actually use to send information in practice. Also, in general, there is no such thing as "proven fact" in physics. You can never prove that a theory is correct you can only ever show where it fails. So "accepted theory" is the best you can get in natural science.
@@entropie-3622 Gravity was my stumble, I didn't see a way that photons could be responsible, Cheers!
@@entropie-3622 quantum physicist, you explained it pretty well, aside from some nip picks. Photons interact with matter via electrons, as seen through the award winning photoelectric effect. There is no coulombic force between photons and matter. And for the quantum gravity, the true answer is that we do not know. The graviton was a hypothesized particle that was trying to unite gravity in the standard model, but couldn’t with our current understanding. It was a pretty solid attempt, but it just doesn’t work with the standard model. Really the only interaction between photons and matter is through the photoelectric effect, and some much more complicated interactions, some you just won’t find in nature.
Qantum tunneling can get faster than light speeds, pulsars can get faster than light jets. Time for an updated vid! Great series though. Keep up good work.
"The problem with traveling faster than light is that you live in the darkness."
I get it
Not necessarily, of you would create a spaceship with it's own Gravity it would be possible to see at least your spacecraft
@@ThePiter it was a joke
Technically you dont. Even if you travel lets say at the speed of light, there is still light in front of you from before, and constantly incoming from other objects in front of you.
Yes, but not for the reason I think you are saying here. If something with mass could travel as fast or faster than the speed of light it turns into pure energy. If a the case of a person, that person would cease to exist as he or she transformed into pure energy and "live in the darkness". Of course this could very be what you meant.
1:34 I’m guessing this line has been spoken by a lot of ED doctors.
OK, I have this thought of rotating a completely inelastic(0 elasticity) pole from one end which is longer then 3x10^8 meters. Now wouldn't the other end of the pole rotate instantaneously? And thus someone at the other end could tell that the pole is being rotated, which can be seen as information traveling faster then the light?
If it were completely inelastic, it would simply break. If it were somewhat elastic, it would bend. No substance is completely inelastic, anyway, because the bonds that hold together atoms and molecules are somewhat elastic.
@@fieldrequired283 it was a hypothetical assumption of course. Since you mentioned that it would break, I think that's what would happen if the stick were to be inelastic but what if the stick is both inelastic and unbreakable?
@@ohihassan693 The thing you're describing doesn't follow the known fundamental laws of the universe and can't be made of matter as we understand it. Since it's fictional magic you made up just now, it can do whatever you want.
