Just thought I would throw this out for Bill S. Phys.Org:Is the universe finite or infinite?Bill Gill
C is not the speed of light in a vacuum.
C is the universal speed limit.

Thanks Bill. I've bookmarked it to read when I have a few spare minutes.
There never was nothing.

Wasn’t it Jim Baggott who talked of “fairytale physics”?
This is an interesting article, but for me, the main interest is in seeing yet another example of how scientists think about infinity. If by “infinite” we mean unbounded, then all these repetitions of repetitions are totally unnecessary. If we mean infinite in anything other than a mathematical (approximate) sense, then what makes us think that the concept of repetition has any meaning in “the infinite”?

It appeared to me that his use of infinite definitely meant immeasurably large. That is there is no bound, and no repetition based on anything like going around the world and returning to your starting point. The repetitions he is referring to are those created by random chance in an immeasurably large space-time. After all if everything that we can observe is based on random happenings, then in an infinite space-time everything that can happen will happen an infinite number of times. On a smaller scale it is unlikely that a person will draw a royal flush in poker, but it does happen, and it happens many times. For us to exist the way we are is unlikely, but if you have an infinite space and time then we will happen again and again.
And of course as he explained we don't know if the universe is infinite or not.

Oops! In case anyone saw that, I posted it in the wrong forum!
My bad.
