paradoxes if instantaneous signals
Would there be paradoxes arrise if information could pass instantaneously? If there where no limit how fast things can move.
I know that in SR when faster then light travel is allowed, the casual order differ for different observers.
Are there paradoxes in the classical Galilean space-time view, which allows instantaneous signals, as well?
Or are speed limits only necessary in SR and GR?
I think that Galileo's relativity is Einstein's one, when c goes to infinity even is many consider that it is Einstein's one at very low speeds.
