• We can’t see very far. Human instruments are very limited, which means that we’re only able to measure up to a certain point. Past this point we aren’t really able to see nor measure, only because our instruments aren’t strong enough.
• We don’t know it the universe is allegedly infinite. Here’s where we get into the territory of explaining something we can’t see. If the universe is infinite as suggestions claims go, then measurement should be irrelevant. Besides, how would we know it was infinite in the first place?

Is It A Finite Or Infinite Universe?

We don’t know. This is one of the biggest flaws with our knowledge of the…
