If it is physically possible to exceed the velocity in which the universe is expanding, can we move forward in time?
It is nothing to do with the rate of expansion of the universe, but it is perfectly possible to travel forward in time.
It is nothing to do with the rate of expansion of the universe and everything to do with the speed of light.
We are travelling forward in time all of the time, but the time experienced is relative to your frame of reference. As a result, it is possible (in fact unavoidable) that we experience different lengths of time according to how we move around.
Most of the time, this time dilation is too small to be easily measurable, but there are some scenarios in which it is much more noticable.
For example, we detect far more muons at the Earth's surface coming from cosmic rays than we would expect. Muons have a half life of about
If we had a spaceship that could sustain a
