Slowing The Speed of Light Down To 2 m/s-What Special Relativity Feels Like

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!

[@DrewFeille]

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.

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.

[@Admiral45-10]

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.

[@g59enjoyer48]

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.

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.

[@CalculatedRiskAK]

I always thought they got length contraction wrong when I saw this effect, but it turns out they were right all along!

[@MultiPleaser]

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.

[@TheSonicFairy]

Warp speed was in Star TREK You said WARS

[@Admiral45-10]

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.

[@michaeljorgensen790]

@@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.

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.

Seriously, you are explaining such a difficult concept in such a simple way! I am a Physicist, specialised in sciences of the matter, and I love your channel that I discovered like a week ago. I tend to understand concepts and idea, and have no idea how how to explain it in an understandable way to someone with no science background. And you do that so skillfully! Great job! I will talk about your channel a lot around me.

So that is why stars look like lines in Star Wars through hyperspace 😯

[@DevPatel-tk5ny]

Exactly

[@sourabhperuri1698]

And also in Doraemon 😅

[@nowaayy_]

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.

Fantastic video. Could you do one discussing the non-0visual impacts of traveling at the speed of light. Everything here was about what our perception would be when traveling close to the speed of light but what lese happens when closing in on the speed of light that's not about perception?

[@SteveFrenchWoodNStuff]

Funny how every episode starts with that line, yet virtually every episode of The Flash features some OTHER person who's faster than Barry, completely debunking the headline claim of being the "fastest man alive"..

[@tenwholebees]

I’m only slightly familiar with The Flash vicariously. How fast does he move? And do the comics or show ever depict it?

[@alansmithee419]

@@tenwholebees the show very occasionally gives a value like "mach 5" and then two episodes later he runs across a desert in half a second or something stupid. In the first episode he dodges *lightning.* never expect consistency out of comic book characters. Or any form of logic at all for that matter.

[@quitegauche]

@@alansmithee419 Obviously consistency in long-running comic book characters is a difficult thing to expect especially for characters with such a long run (pun unintended) in their series. It depends on which iteration of the Flash, which flash (Barry, Wally, etc...) and which media did they come from (TV Show, Animation, Movie, comics, written literature and etc...) However, depending on which Flash we are talking about, they do make an effort to have consistency in their work.

for video gamers, length contraction can easily be explained by taking the example of video game fov.. As in real life the screen size of monitor is fixed but by changing the fov in game we can see more objects and artifacts on same screen size.. for example on higher fov the movement gets faster than lower fov its gets slower.. but for game code and monitor perspective its constant.. same logic is applied in this simulation to give the length contraction effect for not so much gamers, fov- in game field of view mostly used in first person perspective games
