Why does general relativity say that everything is just relational to itself, but then ban the velocities required for that to actually happen?
>>16478636It only bans classical information velocities. Quantum shenanigans are a different story.
>>16478990That's not what I'm asking. If all motion is relative then an earth centric model of the universe is merely choosing a space time moving with the earth and writing the equations from there. Except we can't to that because then stars would be breaking the speed limit.
>>16479032>Except we can't to that because then stars would be breaking the speed limit.how?=
>>16479051Just some quick napkin math so it's probably wrong, but if the earth were stationary in a given space time anything over 500AU away would be rotating faster than c.
>>16479063GR talks about inertial reference frames... i.e. not rotating
>>16479032Well, that's why I said it's about information. You only measure the velocity of things by the photons they emit. You will never receive photons from something that is at the speed limit, at which point it doesn't exist from your frame anymore.Presumably there are things like that outside of the visible universe but we can't have that info.
