How big is the universe?

Is it infinite? Or, do we live in a finite, but just extremely large universe?

I believe I can prove that the universe is actually not infinite through a very simple mechanism.

Please find the hole in my logic. It’s very simple.

## Proof:

- As a thought experiment, let’s first consider what proportion of the universe you (your existence) consists of the entire universe.
- First, consider a scenario where the universe is very small. Let’s say the universe is equivalent to the size of 100 regular sized human beings, then the proportion you comprise of the universe would = 1 / 100 or 1% of the universe.
- Now, let’s go to the opposite extreme. Let’s consider the scenario where the universe is actually infinite. Then what proportion of the universe would you comprise?
- 1 / infinity = 0

In the case where the universe is infinite, by simple division, you would not exist.

Hence, if you believe that you exist, the universe cannot be infinite. It must be finite although probably a very large finite number.

However, is it reasonable to model the universe off of a simple division problem?

Although debatable, to me it’s as good a way as any.

Let me know what you think below…
