It could be talking about:
In the far past of the universe:
Physics might have been different (look up the beginning of the universe—right after that)
I’m not sure there were stars (pretty sure there weren’t planets for a long time) - big differences like that
In the far future of the universe:
Energy might cease to be usable (equilibrium), maybe some physics changes
The stars die out
