- Space and time are just 2 facets of the same thing (spacetime), and this ST has been expanding in all directions since the Big Bang. I can understand what that would mean spacially (galaxies moving apart from each other), but what would that mean temporally? https://www.reddit.com/r/askscience/comments/5xa6wc/space_and_time_are_just_2_facets_of_the_same/ 8 comments askscience
