GENERAL KNOWLEDGE

Detailed explanation-1: -There are probably more than 170 billion (1.7 × 1011) galaxies in the observable universe, [8][9] and possibly more in a theoretical wider multiverse. [10] Most are 1, 000 to 100, 000[11] parsecs in diameter and usually separated by distances on the order of millions of parsecs (or megaparsecs).

Detailed explanation-2: -"So a number like 200 billion [galaxies] is probably it for our observable universe."

Detailed explanation-3: -There may be 2 trillion galaxies in the observable universe, although that number was reduced in 2021 to only several hundred billion based on data from New Horizons. Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction.

Detailed explanation-4: -The current width of the observable universe is about 90 billion light-years. And presumably, beyond that boundary, there’s a bunch of other random stars and galaxies.
