Actually its very possible humans can approach the speed of light especially if you grew up in a mexican household when mama grabs the shoe.

The faster I travel the larger my visible range becomes—that’s exactly what I told that cop who stopped me!

[poproxx]

So maybe in the last scenes of 2001 a space odyssey, the change of colors over land scapes might indicate that Dave was travelling closer to the speed of light.

The shortest interval of measurable time is the time from when the light turns green and the guy behind you honks his horn.

[eyeseeyou]

so going the speed of light is basically like a crazy ass mushroom trip lmao

[jeremywestern]

You can travel at the speed of light but not at night cos it’s dark

[paulhk]

Imagine being on an LSD trip and then entering speed of light

*You would see colors that do not even exist*

[rolandexclusive]

it looks like it feels when you're dreaming and you're trying to run, but barely getting anywhere

[aeho]

Oh time dilation, that's the reason why it takes so long for my dad to come back.

[ronhagelstein]

This just went over my head at the speed of light

Every time I learn something about the universe I rewatch 2001 A Space Odyssey and realize they tried to account for it.

You are sitting on the living room carpet. You are really really REALLY stoned. So much you can't even move. Moving would require infinite energy at this point.

There is a bag of chips on the far side of the carpet. And those chips would be SOOOO good right now. But from your perspective the bag is as far away as Alpha Centauri is from Earth.

Then it hits you! Eureka! Moving at any speed may be impossible, the speed is a constant, but space and time is not. At this point time has ceased to exist, so you are left with only space. You start pulling at the carpet. Space starts to warp ahead of you. The bag of chips appears to come closer. You did it! To travel without moving, that is the secret!

In the vast darkness outside your living room an observer passes by. He sees someone pulling at a rug whilst laughing and grinning madly, shakes his head and keeps walking. Yet from your perspective you are a genius, having cracked the very secrets of the universe itself! It truly is all relative...

Don't forget, not only is there a "tiny tiny tiny time delay" (6:34) because of the time it takes for the light from the screen to reach your eyes, but there is also an additional tiny tiny tiny delay because of the time it takes for the nerve impulses to travel from your retina into your brain and for those signals to be processed.

[chriskaplan]

this video is so clear and perfectly written, his commentary with the game too really makes this all easier to understand

[Shadow-nmzo]

The reason why you seem to speed up is not actually because of time dilation. You will still seem to move at the same speed but distances will get shorter in front of you. This is known as length contractions, where distances in your direction of motion gets shorter. Thus you can travel between 2 points at a seemingly faster speed when in fact is is the path which gets shorter.

"It's like moving in lag"
Me laughing in South African ping...

4:09 not quite. The gravity of Earth also dilates time. The time dilation caused by the difference in gravity for us vs the satellites is much larger than the time dilation the satellites experience from their velocity and is in the other direction. The satellites experience more time than us, they age more. And it's not trivial, it's 0.02 seconds a year. At the speed they're going, they will be at a significantly different location in that time.

I keep catching myself staring at this like a young child watching a magician for the first time. Laughing, smiling, holding my breath in anticipation. Space man, space... Ain't it somethin'?

[DatSimple]

so when dio uses za warudo, the cool colorful effect is actually semi realistic!

since time is stopped, light particles will be hitting your eyes in weird ways
same with the Lorentz effect, as you move around in stopped time,
things will probably get all distorted
