Slowing The Speed of Light Down To 2 m/s-What Special Relativity Feels Like
ฝัง
- เผยแพร่เมื่อ 12 ส.ค. 2020
- In this video I show you what it would look like to slow the speed of light down to around walking speed. So with just walking around town you would experience relativistic effects. I talk about time dilation and length contraction and what it would look like to have it happen to you. Get the simulation created by MIT here: gamelab.mit.edu/games/a-slower...

*Interesting note:* Even Einstein was mistaken on length contraction. He had said that a sphere would look like an ellipsoid. However, Penrose later proved that a sphere would still be spherical, although rotated. Notice in the simulation how the spheres are the only objects that don't look distorted when moving at near light speeds!
Nicely explained 👍👍
Haah, nice try, you still aren't getting my liver.
I thought Einstein was always right.

"The only downside in being faster than light, is that you must live in the darkness"
-Sonic Capable Hedgehog
Heh
@Blue Silver or can you, convert to pure energy and then convert back
So... You're faster than light?
You can only live in total darkness if you start travelling during the Big Bang... Otherwise, it'll be a long time before you get to the edge / boundary of light... and then you'll be living in darkness.
@@muhammadtahaali614 latom
when you sarcasm is too advanced
The problem of moving faster than light, is that you can only live in Darkness
Here's one way to understand why things seem to get farther/longer at high speeds:
Normally your eyes only catch light coming from a certain direction in front of you. But as you go faster, your eyes can catch up and intercept light that would normally be outside your file of view.
So imagine that your eye is a bucket with its opening facing forward, and light photons are pellets being fired all around you. At rest, the only pellets that can enter the bucket are the ones in front. But if you move fast enough, you can outpace pellets that are traveling sideways, or even ones that are coming from an angle behind you, so your bucket can catch more pellets from a wider angle.
If we go back to thinking about light: this is why the camera seems to zoom out when moving forward. Your eyes can now catch light coming from angles to the side, or even behind you.
This is a good explanation.
Underrated comment
This is really good example,,,,,
Wow, you made a great analogy
brilliant
For understanding the Doppler effect in real life, I use sound - for example, when riding on a train and going past crossing bells at speed, or if a vehicle with sirens goes past, et cetera. The pitch audibly changes between coming towards you and going away.
You can also use it in smaller examples: for instance, if you want to test a dog wistle, all it takes is for you to ride a bike away from it and you will start hearing it. It's also when an ambulanse is near you, you hear it loud and high-pitched, but as it passes you sound gets quieter and lower.
"If you want to live longer you have to move more"
Turtles: Are you challenging me?
It's relative 😀
Yoo man most realistic and challenging comments
Even the turtles move but A Banyan tree never, yet it lives much longer
@Prince Kashyap what if the banyan tree moves, but it moves the earth along with it?
Everything depends, i think that comment he made was misused. Like the guy said above here, trees doesn't move, yet that there are ones that live hundreds of years, turtles are another good example, there are athletes that die young from any reason, so everything DEPENDS

I once played a game about a velocirraptor that changed the speed of light to 3m/s and it was really interesting. It explained weird relativistic effects, but in a third person camera. You could do cool things like keeping a powerup more time than you should or passing between fast moving platforms with time dillation, slipping between really close bullets, moving so that two different coloured objects appear the same to you because of Doppler effect, etc.
Nice video!
Will be interesting that effects in a videogame with speedsters, like Flash, Superman, Ben10 XLR8, Silver Surfer, Sonic, etc..
@@pilarrosanas5085 yeah, i thought of Flash too, but for movies. They show none of it, just freeze frame
What was the name of the game?
Oh yeah I remember that game.
I always struggled with the colour puzzles on that game
“ if you’re moving close to the speed of light it appears as if you can get from point a to point b faster than normal” ...well yeah
The point is, your speed actually stays the same, only the light slows down.
You actually take the same amount of time to move from A to B no matter what the speed of light is. But it does not appear so from your perspective.
Its relativistic space time dilation, not increased velocity. Remember, he is always moving at 2 meters per second throughout the whole game. He is decelerating light, not accelerating himself. So the contraction of space creates an acceleration like effect where distances that took 5 seconds to travel start to take 4 seconds then 3 seconds, so on so forth. The space between himself and his destination is contracting as the speed limit of the universe decreases, bending the rules of relativity into a more observable state.
@@g59enjoyer48 I was making a joke but that’s actually helpful
Ah, I am very literal at times 😅 I'm glad it helped your understanding though! I had trouble with this video at first, its very confusing
*the speed of light is slowed down to walking speed*
This explains why when you drink a speed potion or sprint in Minecraft your screen zooms out.
It's the same in some other games too. For example Goat Simulator, When you have a suger rush your screen zooms out a whole lot.
and when you use /effect to give yourself speed 255, you screen becomes extremely distorted.
TBH it's more about mimicking the effect stimulants do to you.
Holy ducking shit
Ha, I wish. It's really because a change in FOV presents an illusion of moving faster. If you disable that effect, you can see that speed potions or even sprinting just aren't all that fast-seeming without the FOV change.

The "stretching out" part perfectly explains what happens to the stars in "warp speed" in sci fi movies like Star Wars. The stars get "stretched" to thin lines outside the ship's windows.
I always thought they got length contraction wrong when I saw this effect, but it turns out they were right all along!
Hyperspace and warp speed are totally wrong.
At warp 10 it would take just under half a year to get to the nearest star.
All the stars in the sky would bunch up, moving forwards, none being seen out the rear windows or side-rear windows. All the stars would be in side windows or in front windows.
And they would all be either red or blue, except a few that were shining into your side windows, which would still be white..
But, keep in mind, the stars in your side windows had just bunched up, and had been behind-and-to-the-side just before you hit the hyperdrive button.
So, the only white stars would be the ones you are traveling away from at a very specific angle. And only that angle.
Warp speed was in Star TREK
You said WARS
Interestingly, if you lived on planet far away from Earth, and then moved with speeds near speed of light or even faster¹, you'd feel like you're time-warping into the future, and if you did the exact opposite and looked at Earth, it would appear to you you moved back in time.
@@MultiPleaser "At warp 10 it would take just under half a year to get to the nearest star". Warp 10 in Star Trek does NOT mean 10 times the speed of light. Most trekkies say that warp 10 translates to 1000 times the speed of light. Around 36 hours to the nearest star.

So according to this flash would be colorblind
Good point😂😂😂😂
Flash is fast. Faster than Superman. But his speed doesn't even come close to speed of light. I rather think about how the cameraman can film flash when he runs
@@nowaayy_ In a comic, flash can go 300 trillions of time the speed of light but that's without taking into acount space contraction. He would still go at atleast 99,99999999999... % of the speed of light though.
@@josenobi3022 I didn't know that it's noted in comics. Then DC must watch this video it's nonsense😂😂.
@@nowaayy_ No, DC is right, it's just the guy that calculated the speed didn't take into account the space contraction.
The speed wasn't written in the comic
That last bit made me think about that feeling of vertigo you get in dreams; you know, when you try to run forward, but the thing in front of you goes away. And then I start thinking about how in a dream, years can pass within the six hours of a night's sleep. Kinda sounds like time dilation to me. What if people already subconsciously know how time dilation and the speed of light work
Nah, it's more because our brain doesn't actually know how much time passes, the "life" you live there is hella shortened, you won't have those 18 years of school and 60 of work where everyday you wake up and all that shit, it "feel" like a lifetime, kinda how playing for 4 hours could feel like 2 and studying for half an hour could feel like 3 hours
Dreams are just false memories, though. So don't think of it as a representation of reality, think of it as a representation of memory recall.
@@entiretotalityofwhateverexists yea, its not like it happens exactly the way time would dilate. its rather random
@@gandalf8216 Actually, dreams are modifying the algorithm in your brain and doing probability checks like a neural net.
@@gandalf8216 dreams are not false memories. They are simulated realities that help consolidate real memories and create real memories of these simulated experiences too. They can become more "false" in the process of dream memory recollection after waking up, but that's another thing.
Very well done, mate. Interesting video. Congratulations on the research and production. Enjoyed it thoroughly.
So... the artistic vision of hyperspeed in sci-fi movies was actually true ? This is mind blowing.
Yeah I was so surprised he didn’t just show the millennium falcon just travel through space, seeing all the stars turn into white lines in a tunnel. Quick and easy way to visualize that effect.
Yeah or the uss enterprise, my mind was blown that all of that was an accurate representation of light speed
tbh i think the effect in movies represents motion blur
Actually, all sci fi movies have it totally wrong, epecially Star Trek and Star Wars.
Firstly, you would rarely pass a star. The space ships never travel very far at all.
Secondly, all the stars would move forwards, towards the direction of travel. They would bunch up, with none behind you.. And they would all change to blue or red, except for the few stars whose light is coming from a slight angle from the side, those would stay white.
The sky would just sit there for many years not changing yntil you reached the closest star, about 3 months after you hit the "warp speed" button, or went into hyperspace.
Boring-ass movie, though.
@@MultiPleaser "The space ships never travel very far at all"
Have to consider fiction part of sci fi.
Considering if spaceship does move that quick that it reaches stars. How would it change?
So is that how "The Flash" see things when running? Interesting..
No that means no one can move at the speed of light without crashing
@@castleold19 but the faster u go the slower time is for you. So he whoud look like he's in slow motion

I really appreciate your brilliant explanation! This simulation helped me a lot, and has so much value for physics education!
So if i was standing 1 meter away from a mirror, would i see myself one second in the past?
i don't know, no one have try it before
@@Gus_Fringus Yeah, i think they should try it..
Yes, with speed of light at 2 m/s, even a mirror would have one second latency when viewed from 1 meter away. However, assuming the universe works according to the same rules otherwise, your brain would have equally high latency so you wouldn't notice it.
@@MikkoRantalainen ok thanks for the info. One more thing, when we look at the Sun, aren't we seeing it in the past? I mean the Sun is so far away from Earth that it takes 8 minutes and 30 seconds for light to reach us. So does that mean we are looking the Sun 8 minutes and 30 seconds in the past? If this is true, then everything we are seeing is in the past right? Even if it is 0.001 seconds?
@@pinkpanther1139 Yes, the light that comes from the sun was emitted over 8 minutes ago. The distance from the Earth to the Sun is not constant so the delay changes a bit over a year. Most of the things are close enough to your eyes that the time delay due speed of light is not meaningful compared to your senses and brain performance.
I love how this guy gets right to the point in such a friendly way. Just human, not pretentious or obnoxious at all. Breath of fresh air👍🏼

Very interesting, made me think of the sonar fish finders we use, with different Doppler effects affecting the readout dependent of the speed the boat is travelling at. Thinking about observable reality being a read out of signal return traced in time and relative speed. Also if you were completely static with the universe moving past us, what would we see?
So that is why stars look like lines in Star Wars through hyperspace 😯
Exactly
And also in Doraemon 😅
It's a lie in star wars. If you could move near at the speed of light in space, stars would not look like lines, because they are too far from you. But when you get closer to a star like we are relatively close to Sun, maybe you would feel this effect I think.
Imagine if there was a slight miscalculation in the jet’s system and they crash into a planet at the speed of light

Wow Nicely explained
I see time and space simila to quantity of movement: on object could move straight or rotate on itself, or a mix of these two. The important thing is that the total quantity of movement remains the same. It seems the same with energy and time: when you gain energy (by acquiring speed or by staing near a mass) you loose time, and viceversa.
Would love to see different perspective with stationary observer looking at you while doing this simulation.
3rd person view of the 4th dimension travel. Gonna make a big steppy or normal steps stretched out and really fast. Lol this is a fun thought you've started.
I was waiting to see that too. Like a side by side split screen or something
For some reason..this is actually scary to experience..
I have had this question ever since I realized the stars we are looking at are actually light waves finally reaching our eyes from however many m(b)illion years ago. Obvious theoretical question: If you look directly at the surface of a planet (looking at trees, water, lava, some weird fish frog, etc.) in a distant galaxy, and you travel directly to it, without ever breaking direct visible contact, would you being seeing time as "sped up"? The light reflected off the planet, and into whatever advanced machine that could ever bring in that amount of light and allow this to be possible, is essentially just a timeline in which you would be travelling through.
How much would the speeds of which we are travelling effect what is being observed? How fast would you need to go to see things as sped up? If you could travel faster than the speed of light, what would happen if you went the opposite direction? Could you perceive time on that planet as reversed?
That is actually mind blowing. Amazing how you can perceive a distant object at different states of time, but the object itself is in the "present".
To answer the first set of questions, you would absolutely perceive the events occurring on that planet as though they were sped up. This would pronounced at any relativistic speeds, so anywhere in that .7c-.9999c range. We could do the calculations to determine just how fast those events would unfold before your eyes, but to simplify, imagine you are travelling towards some planet a lightyear away at 99.99% the speed of light. To an outside observer, you will reach that planet in approximately a year and some change; however, to you, that trip takes only about five days. Yet in those five days, a year's worth of events occurs on the planet towards which you are travelling.
As for the second set of questions, it's difficult to say how one might perceive the universe when travelling past the speed of light, our mathematical models fall apart at that point. That said, if you were to move away from that same planet from earlier at near the speed of light, you would still counterintuitively perceive that it was sped up, because time dilation doesn't care about about direction. That said, where when travelling towards that planet it would appear brighter and bluer, moving away it would appear redder and dimmer.
Interestingly, and where this all becomes rather confusing, is that the light itself, those photons with the information we're looking at, will always be perceived as moving at the speed of light, regardless of how fast or in what direction we are moving. As an example, let's say that in the very first second of your trip, when you are going 99.99% the speed of light towards the hypothetical planet, if you were to broadcast a radio signal to that planet to tell them of your arrival, they would receive that broadcast three and half days before you arrive and not a second sooner. Although that broadcast was sent from your ship going near the speed of light, it would never gain any additional velocity, and both you and those who received that message would agree about exactly how fast it travelled even though you would disagree about the amount of time it took or the distance it travelled
Edit: I was incorrect about the moving backwards hypothetical
@@eclatdeepurer5894 Socrates hit on this a long time ago. Sight requires three things. The thing to be seen, a thing that sees, and a mediator between the two.
I love this simulation so much.
why you collecting 100 orbs to get that effect when you can just smoke 2 joints?
What parents think we watch: fun silly videos

Oh really

This is the perfect use of video games for learning.
Thank you this is great for Star wars simulation
In the near future:
"Hello everyone, today I'm going to pour an ocean into the sun to see if it goes out"

@@jettaeschroff6924 ok nice. you watch lets game it out? its pretty much same as graystillplays

I love this, it's amazing to get to see concrete visualisations of these very abstract concepts. But I was wondering how come we don't see any difference in the movement of the ghost-people, shouldn't they be stretched/squished/rotated/blueish/redish as they move when you're still?
i think it's just a filter and not an actual calculation
AMAZING VIDEO ❤️❤️
Great Video!
