Q&A: Cosmology
Q:
The thought of an expanding universe is fascinating. With that
in mind, can "time" or the passage of time in our reality, speed
up or go by faster?
A:
It is all relative. Time in a galaxy in the galaxy cluster 3C295
that is receding from us as part of the overall expansion of the
universe will appear to pass about 46% more slowly to us since
it is located at a distance corresponding to a red shift of 46%,
or about 5 billion light years. Conversely, residents of that
galaxy would observe that our Milky Way Galaxy is receding from
them, and that time in our galaxy is passing more slowly.
