How many stars and galaxies are in the non-visible universe?

Answer 1

No one knows.

It is actually impossible to determine the number of stars and galaxies that exist in the non-visible universe, and we stand nowhere in our universe.

Finding out how many stars there are in observable galaxies is also a challenging task.

You can't even estimate how many stars there are in a galaxy if one billion stars are assumed.

The observable universe, sometimes referred to as the non-visible universe, is thought to consist of 100 billion galaxies, with an average mass of approximately 100 billion stars. This estimate is subject to change based on the most recent observational data and scientific models.
