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

[@TheActionLab]

*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!

“ 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

[@chri-k]

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.

[@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.

[@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.

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.

Length contraction is something happening in coordinate frames. But if we look at something, the speed of light and the distances come into the game. Let's say two events happen at the same time at different distances. Coordinates (t,x,y,z) will tell that these two happened simultaneously, but not our eyes. Further will be seen later than the closer one. Nice video!

Another example of the Doppler effect is when you are by a race track, the cars driving really fast as they go towards you, you can hear the engines at a higher pitch. Then, when they drive past you, the sound gets lower. Because the racecar is closer to the speed of sound, the same applies to light

[@SupremeDP]

Oh shit you're right!

[@richard_from_england333]

It's because the sound waves get shorter as the car approaches so it sounds higher (the sound is the same length from the car's perspective but from yours it gets higher because more sound waves keep hitting you so it appears to be higher) and they get longer as it moves away so it sounds lower

[@jbh759]

[@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.

[@ashrylka_2606]

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.

Wouldn't it be absolutely awesome if someone made a puzzle-solving adventure game that involved manipulating this 'light-slowing' effect as a core game mechanic?

I appreciate the info about the Terrell effect - thanks! You just helped make a novel I'm working on more realistic :)

The Forever War has been my favourite sci-fi novel ever since I read it as a young kid in the early 90's. I've been continuously disappointed by almost all sci-fi disregarding relativity as inconvenient to the plot instead of incorporating the consequences as part of the story telling. Would you mind expanding on the premise of your novel as you've really piqued my interest?

[@macronencer]

​@@beardedchimp Thanks for your interest! Unfortunately that novel is one of two that I was developing simultaneously, and I decided to put it on hold because the other one was more promising. However, I've not abandoned it so I might pick it up again afterwards. The scenario isn't fully accurate and was meant to be a description of a spectacle really. It's about how a star might look if you passed close by it while using a warp drive. I hadn't fully figured out the distortion and spectral effects but this video gave me some ideas for research avenues. For example, I described the star as having coloured bands like an Easter egg, and being "flattened" into an egg shape at one end - but after seeing this video I began to wonder if that was the opposite of what you might see. Of course, warp drive is speculative anyway so there is some "wriggle room". Anyway, the other book isn't done yet but I'm happy with how it's going so I'm guessing that if either of them gets published it will be the other one, and my "Easter egg" star idea will have to wait.

[@jammerc64]

As time slows down, you're seeing more and more distant past, hence if you travelled in space you see objects as you saw them from increasingly previous point of your travel. hence the stretch which seems actually pretty straightforward.

[@Manoj_Kumar1973]

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

[@outandabout259]

When I saw the stretching, the first thing I thought was: FOV increased. And the reason I thought was (I hope this makes sense): When light hits a thing, it is reflected everywhere. If I stand still and look at something, I see the light it reflects directly towards to me. But if I move at nearly speed of light, that light goes way behind me and instead I see the light that was reflected more forwards. Therefore I see the object at my side when it is already behind me. From my viewpoint, light that was reflected parallel to the direction of my movement comes always at a slight angle, no matter my speed, because I move closer to the line those photons move along. The faster I move, the greater the effect. At speed of light I move as much as photons, so I see things directly at my side at 45 degree angle in front of me. And things at 45 degree angle behind me seem to be next to me. The faster I go, the further behind me I can see, but seeing full 360 degrees would never be possible. I hope this makes sense but I am afraid it doesn't... As a finnish high school student, I am not sure if my english is good enough to explain my thoughts 😅

[@thenerdfollower3651]

I like this

[@yarkehkeh]

"what it would look like is that everything becomes spagettified out really long. The closer you get to the speed of light, the more stretched out everything gets infront of you and also the faster it seems you're getting to each place". Sooooo basically the hyperspace from star wars is actually very scientifically correct?

[@bhavyakabade]

I was thinking the same exact thing.... the artists did get it right

[@Admiral45-10]

Both yes and no: +) Yes, this is how it would appear to you -) they forgot about Doppler Effect, making everything appear violet -) you don't need constant output of energy to sustain constant speed. -) there is no possibility for any energy-based engine to exceed speed of light -) even with 10x the speed of light, travelling through space would still take a long time. For example, if you used such warp drive to move from Earth to Proxima Centauri star (the closest one we know), it would take you just under 5 months.

[@csharpner]

The reason that things look like they're further away as you move towards them ad relativistic speeds is because the ANGLE of the photons coming from your left and right are now coming to you from angles in front of you. This causes your field of view to get compressed in front of you and expanded behind you. It's not little to nothing to do with length contraction. Length contraction DOES happen, but that's not related to things appearing to zoom in or zoom out when you move back or forward.

[@cristoffamolar7922]

[@NoncingAppreciator42069]

I noticed that when you showed the simulation of the length contractions, you could actually see the stuff behind you. Which means that you can move so fast that you can catch up with the light that's going from behind you past you.

[@sourabhperuri1698]

Actually, I don't think that can happen. Even to us moving at near the speed of light, we would feel that light is travelling at the same speed as when we are at rest. But, I don't have an explanation for your observation.

[@dsdy1205]

@@sourabhperuri1698 that would be true if the light was going in the same direction as you. However, it is not - the light is travelling at an inefficient angle,and hence it's very much possible for you to "catch up" with the light because the component of its velocity in your direction of travel isn't all that great. that's from an external perspective. from your perspective, space distorts to allow the light to reach you from that angle.
