    ........a cosmologist appearing on the Science Channel said, "We cannot see the edge of the Universe." A further argument that the Universe is infinite is dimension, and against the Big Bang theory. At least someone understands how compression waves work.

    No, no it's not.

    Can you see the edge of the Earth's atmosphere from your apartment's balcony? No? Does this prove that the Earth's atmosphere is infinite?

    jb,

    what does this mean, from your link?

    and btw insisting that there was a ''beginning'' and there is an ''end'' is Biblical! :D:D alpha and omega

    Basically, it means light/radiation from objects past a certain distance hasn't reached us yet, creating a horizon past which we cannot 'see'.

    Eagle can probably explain it in greater detail; I'm not a math person

    We do not know there is an end. And is likely that humans will never know.
    But one thing is certain it will not matter to any of us whether we know or not.

    Red shift.

    We've seen that the universe is expanding. That means, when played backwards, everything comes to a single point. This is the 'Big Bang'.

    This left two possibilities: a finite expanding universe or a form of solid state in which ever more matter/energy came form somewhere like a white hole.

    The law of the conservation of energy rules out the second possibility. Meaning the amount of matter/energy in the universe is finite.

    Through mathematics that I'm not going to claim to fully comprehend, it has been determined that 'TBB' was not merely matter moving through space, but rather the expansion of space-time itself.

    We're reaching the point where the mathematics involved became too much for me and I stopped trying to grasp all the details.

    also, the expansion of space-time and the finite nature of matter/energy are what bring about the whole entropy thing
