“No, since universe means everything, you cannot have 20 trillion “everythings”.”
Such an early 21st century mentality. Just because the universe has everything in this physical reality, it doesn’t mean that the universe contains all physical realities from everywhere.
A bit snarky this morning huh?
the universe : all of space and everything in it including stars, planets, galaxies, etc.
We can find new things (new to us), that simply adds to the universe we already know.
God bless you, I’m on my way to church now.
