What questions do you still have about infinity?

I still have many questions on infinity as I am sure many people do. Although much has been explained through years of discovery, it is very hard to discover everything about something that never ends. One of my questions, although unreasonable, is what is at the end of infinity. Yes, by the very definition infinity never ends, but human brains can not understand or fully comprehend this concept as everything in our lives has an end. So, I can’t help but wonder what is it like at the end of infinity, if I had God like powers and was able to see every number that existed how would math change. Of course, there is no end so it wouldn’t be plausible to even attempt to resolve this question. Logically I know that no end exists, yet I still wonder.

Another question I still have about infinity is non-terminating, non-repeating  decimals. If infinity is not a complete number how is pi a complete circle? To me something you can clearly see has an end, should have an answer that ends, but instead you are left with a number that never ends.

Infinity is a concept, that has been contemplated by many philosophers. It is hard for us to understand as humans something that never ended. Everything in our lives end. High school will end, our careers will end and our lives will end but infinity will continue forever. These questions are difficult and some what impossible to answer but much to easy to contemplate. You could spend a lot of time contemplating and wondering about infinity and maybe by the end of our life times, something new will be discovered, but there is still so much to learn about infinity.
