infinite space

Crash,While I think that science has successfully evidenced a lower end to at least the classical universe (when you have to represent a location of a particle with a wave function, it's hard to say you can get better resolution than that), I would contend that the evidence that there is an upper end to the size of reality doesn't seem so clearly defined. What evidence do you think suggests conclusively that the size of the universe is finite?------------------
