Question

Briefly define the meaning of the universe.

Answer 1

"The universe" means "Everything".

That's all mass, all energy, all space, all time.

Intriguingly, in the Hebrew language, there's a single word that covers it: " Olam "

Answer 2

The universe is all existing matter and space considered as a whole; the cosmos. This what you were looking for?
