How big could the entire universe be?

46.5 billion light-years
The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light-years or 4.40×1026 m) in any direction. The observable universe is thus a sphere with a diameter of about 28.5 gigaparsecs (93 billion light-years or 8.8×1026 m).

How big is the universe beyond the observable universe?

They found that the universe is at least 250 times larger than the observable universe, or at least 7 trillion light-years across.

What is beyond our observable universe?
