Eternal recurrence

  1. May 8, 2003 #1
    Lectori salutem.

    Can anyone refute the finite space/energy/matter in infinite time theory?

    Finite space/energy/matter implies that the universe is not something endlessly extended, but set in a definite space as a definite force.

    Infinite time implies that it has never begun to become and will never cease from passing away.

    This means that the universe consist of a finite amount of energy (in whatever manifestation) that flows on in an infinite stream - not infinitely deep or wide, but infinitely long.

    Thanks in advance!

    You should probably post this on the Philosophy board.

    And why is that - is it beyond the grasp of physics?

    So far all measurements show that net energy of universe is zero. Same for all other conserved values (charge, momentum, etc).

    Volume is not a conserved value.

    Actually not even atoms.

    Oh, conserved. My bad.

    Fields only then? Well, it was a pretty close guess, considering it was made thousands of years ago.

    I am not interested in "net" energy. Of course the net energy is zero: otherwise it should have a positive or negative charge in relation to something else. But I am talking about the whole universe.
