Okay, I give up. If you insist on putting limits to infinity I am unable to present a coherent argument. All I will say is you haven't thought it through.

ie: Where does that degraded photon energy go?
How do you know infinite space is possible without infinite time?

This is a great thought exercise for expanding your personal universe. Think about the ramifications of infinity long enough and it begins to collapse like a house of cards. Anything and everything is possible-- no, not possible but has occurred an infinite number of times.
So maybe the universe is infinite.

But I don't believe it. The universe is finite.
