>>12390084>So the analogue would be the speed of light, right?speed of sound isnt a constant and things could move even faster. it depends mainly on density of gas/liquid/solid.
speed of light is a final upper limit. and moving with that limit spacetime can not be perspectivated as normal.
there is no distance as if you would travel with a car or something. this speed will bend your destination towards you.
distance is no more given. trying to imagine this does not work. do not try to derive ideas from this, its not working.
>But what if space is thought as medium that propagates matter as well? What is the speed in which matter can propagate in vacuum?the LHC accelerates matter to 99.9% of c. i suppose the attempt to bring uncharged and intact masses to this speed will not succeed,
because the binding energies of the molecules will eventually cause problems. but I have no clue here.
