time is constant with space
space is a physical thing
physical things are stationary in time, this means the apple on your kitchen table isn't the same apple it was 5 seconds ago, or 20 hours ago(it has aged, creating a completely new thing)
which means time is stationary in time
kind of confusing, but basically this means that time isnt really a long continuous thing as you may picture it, but rather an infinite number of moments that play out in a certain order
so there is no possiblity of rewinding time, but there is a possibility of traveling through time, which would be to consciously be in one of these past times, the same thing as rewinding time
since time and space are constant, and space is curved, you could travel outside the domain of space(not space as in outerspace, but space as in our physical dimension, the space between you and your tv etc)
now you just have to figure out how to travel outside space
its like if you were a virus on a petri dish you would never know there is a whole other world outside, you have to climb out of the petri dish and climb into the one next to it to travel back to a previous moment in time
the only way to rewind time would be to travel back in time
