Universal Sizing

The observable universe spans about 93 billion light-years in diameter, meaning we can detect light from objects up to 46.5 billion light-years away in any direction due to cosmic expansion.

This region contains an estimated 2 trillion galaxies, each with billions of stars.

However, the unobservable universe—regions beyond our current light horizon—could be vastly larger or even infinite, depending on the universe's overall geometry and inflationary history.

Some models suggest the total universe could be at least 250 times larger than the observable part, making what we see only a small fraction of the whole.
