How many clusters are there in the observable universe?

With further advances in the telescope-technology, for higher-than before-limits, these approximations might be revised, in due course of time. The size 27.64 bly includes, by extrapolation, yet-to-be-detected virtual antipodal universe...

According to , There are about $10$ million $(10,000,000)$ superclusters in the observable universe.

10 trillion kilometers times 45 billion light years. The distance light travels in one year times the size of the observable universe in light years.

astronomers have put current stellar population at roughly 70 billion trillion ($70*10^22$) Since a glass of water has many moles of water , and each mole contains about $22*10^23$...

Since we can only observe the observable universe, we don't even know how big the universe is. We don't even know how big the universe is, how then are we...

The observable universe is 45 billion light years in diameter and is actually 'shrinking'. Objects outside the observable universe are not seen because of this reason. The light that came...

There are billions of galaxies with billions or trillions of stars in each. So, we can't really calculate the $ of stars, so the best response would be infinite.

I assume that your 1010 means $10^10$. Then the number of stars is simply $10^10*10^10=10^20$.

According to , "The Milky Way contains between 200 and 400 billion stars and at least 100 billion planets." Then they talk about some vague objects that may or may...

Remember that the Universe is expanding. When we observe something in the Universe, the light is traveling toward us, but that thing is moving away from us. That means that...
