Thesis: The universe is infinite.
Proof: self-evident. Our mind cannot comprehend infinity and we haven’t found the end of the universe, and deep within we know we can’t, because if we find its end, by definition there must be something beyond it, otherwise the whole game just continues as before. Infinitely.
Followup thesis: You do not exist.
Evidence: Nothing exists.
Proof: Something finite cannot exist in something infinite. Something finite in something infinite would have to be infinitely small, and infinitely small is still infinite; a concept based on infinity.
Conclusion: The only way you can exist is if you are infinite. And then you are everything and/or nothing. The former defies your definition as an existing entity, the latter means you do not exist.
We try to deny infinity the best we can by ignoring it most of the time, but it is omnipresent part of our experience.
Infinity is the almighty overwhelming power that can humble our ego by showing us our nonexistence.
Who dares to look?
It does not matter. You are looking all the time anyway.
