If light travels without time why does it take such long periods of time to reach earth? Is there something faster than light? Is it space? From the perspective of a photon it would reach its destination instantaneously—but it’s not literally.
>>
time is relative. as you approach the speed of light, you *experience* time faster, until you reach the speed of light (which is impossible if you have mass) and you don't experience time anymore, meaning every single event happens at the exact same instant. but a stationary observer experiences time the same way we do. how light experiences time is irrelevant to them because time is relative

it does travel with time though.

so I don't slow down light for other people when I yawn? wow. im gonna have to think.
>>
Space expands faster than light. Yes. Light is the limit of speed within space. Unless there’s a way to manipulate space there will never be a way to surpass this limit.

The Universe is a closed machine with a finite power source.
the proof? the speed of light limitation
>>
>>16819513
There is no light's frame of reference. There is no photon's perspective.
If you were almost at the speed of light you'd have almost infinite speed (as in s/t) and arrive everywhere almost instantaneously and experience almost no time. But light is not almost at the speed of light, light is exactly at the speed of light. And relativity depends on the fact that there is no light's frame of reference. If you assume light's frame of reference you can't use the implications of relativity anymore. It's like trying to build a brick tower and then removing the first brick, the tower's no more.

Even if in the limit of your mathematical model you get infinity for the lorentz factor that doesnt mean that's what actually happens. Just like with black holes, if spacetime really warped infinitely at the singularity then even after the hole had evaporated, the singularity would remain since you only have a finite mass and thus finite "warping" to remove.

it's crazy you can make the whole universe age just by moving fast
>>
>>16819547
Does this mean that you could move at speed 0 by thrusting in a certain direction and slow down the passage of time?
As, we're already travelling at 1000's of kms an hour just by standing on our planet, but if if we hoped on a ship and travelled in the opposite direction, we could reach 0 speed, because if we do nothing were always sliding forward
>>
>>16821647
Or, what would you have to do to move through time as slow as possible?
