    Big Bang, Deflated? Universe May Have Had No Beginning

    Big Bang Abandoned in New Model of the Universe


    A new cosmology successfully explains the accelerating expansion of the universe without dark energy; but only if the universe has no beginning and no end.

    article:
    other theories predict there was once a cosmic "bounce," where the universe first contracted until it reached a very small size, then began expanding, Brandenberg said.

    Either way, the universe was once very, very small and hot.

    "The fact that there's a hot fireball at very early times: that is confirmed," Brandenberg told Live Science. "When you try to go back all the way to the singularity, that's when the problems arise."


    So this thinking does not entirely deny Big Bang, just describes it in a different light.

    And this is how for decades I've intuitively thought is how it might work. And that happens to coincide with how I later learned Buddhism also thinks about it, this non-Western way of thinking non-segmentally.

    In this sense then, Big Bang is less like a beginning and more like a breath of a body or a restore point on some great big computer.

    But even if Big Bang, that original spark, was something from nothing, even that doesn't deny by itself one universe taking place in one place while another might be occurring in another place, dimension, however that's described and so even without this particular theory there's still room for big bang and for infinity.

    ...The Buddha said that sooner or later, after a very long time, there would come a time when the world shrinks....

    ...But sooner or later, after a very long period, this world begins to expand again...

    big bang and infinity are contradictory

    Not necessarily...

    Even if the big bang model were to be proven correct someday, that wouldn't disprove infinity because there could be several other big bangs happening far away as well.

    I've always questioned the big bang theory anyway. Not because of wondering where the singularity came from, but because of how the laws of physics seem to break down...kinda like the "singularity" in the center of black holes.

    Seems like a new form of mathematics may need to be developed to figure out the real answer, but for now the "infinite universe" seems to make the most sense, to me.

    One of my friends used to call that his popcorn theory. He used to work at Griffith Observatory.

    I agree, somewhat; but its' always referred to as THE big bang (a singular occurrence that created everything - which I doubt is the case).

    Or it could be THE big bang that catapulted the existence of life as we know it.

    The Big Crunch
    http://en.wikipedia.org/wiki/Big_Crunch
    ...one possible scenario for the ultimate fate of the universe, in which the metric expansion of space eventually reverses and the Universe recollapses, ultimately ending as a black hole singularity or causing a reformation of the Universe starting with another big bang...


    The Big Rip
    http://en.wikipedia.org/wiki/Big_Rip
    ...the matter of the universe, from stars and galaxies to atoms and subatomic particles, is progressively torn apart by the expansion of the universe at a certain time in the future...


    The Big Freeze
    http://en.wikipedia.org/wiki/Future_of_an_expanding_universe
    ...expansion of the universe will continue forever. If so, the Universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario is popularly called the Big Freeze...
