Wild question i've been wondering for some time now: what if the speed of light suddenly became infinite? The thing that would be noticed first would be that the (night (only?)) sky would be completely white as the light from all stars that currently exist would come to us on the literal same moment as it leaves. Color shift (red shift and blue shift) would also be eliminated, and we wouldn't have to worry about time delays with spacecraft, making, say, driving a rover with a joystick possible. But i wonder what would change beyond that?
