If time goes forward by the expansion of the universe then could u contradict it by moving the opposite way?

Question

I am of course talking about moving at the same speed and in outer space, my question is because of “Einstein’s theory of general relativity”

Answer 1

Time is not defined by the expansion of the universe. Nor can you "move the opposite way" from the expansion. Galaxies are not moving through space; space is expanding between them. In all directions equally. There is no preferred direction to move "opposite" of.

Answer 2

There is a famous quote from Emmy Noether "if things are

in reversible symmetry, then there is a conservation law somewhere.  Time's arrow means that some things are not conserved and not all things can run backwards so even in a

collapsing universe history wouldn;t revisit the past
