I have always thought of that as a serious possibility. I have argued in other science forums that intuitively the totality of existence is infinite, because logically once you come to the border of your finite universe, what is on the other side? Its been argued that there is no other side because the space somehow bends back on itself, thus finite. That is equally a possibility. However, I have come to appreciate Kurt Gödel’s axiom that a system cannot prove its operations without referring to something outside and greater than itself. This is not his exact words but that is what it amounts to. He called this The Incompleteness Theory because it has no end; the proofs go on forever. In fact, the proofs also have no beginning either. Thus the universe must be infinitely micro as well as macro. Infinity is certainly a hard concept to master even for the greatest minds. Infinity especially throws a wrench into many mathematical equations. But it is what it is. Unfathomable.
Preon
This is the second post I have made in this forum. It is about a theoretical massless particle called preons. It is also my user name. According to some astrophysicists, there is an idea of a hypothetical ultimate particle dubbed a preon that is the true God Particle of mass, although the particle itself is massless. Just when I was getting use to the Higgs boson / field as a stand in God Particle, comes yet something even smaller. Any comments?
