Comment on If something could rotate infinitely after being initially pushed, would the initial push disqualify it from being classed as perpetual motion?
If you think about it, when the universe cools down, maybe some rocks will fly forever without hitting anything.
A cooled down universe does not move at all AFAIK. please Look up Brownian motion.
If a rock is moving between galaxies, what would make it stop?
Does a given mass ever get outside the influence of both galaxy’s gravity influences?
Why not? When two galaxies collide some rocks can get enough speed to escape.
