    It seems difficult to imagine that everything we’ve seen our whole lives, let
    alone the whole world and entire universe, was once concentrated into a
    tiny pinpoint. How could we know this phenomenon ever existed, since
    obviously no one could have been around to observe?

    Also, why the size of a pinpoint? Why couldn’t it have been the size of a marble,
    a house, the earth, or even a galaxy? Actually, the pinpoint has been said to have
    had both “infinite density” and “zero size”, two descriptions of quantification which
    seem quite logically inconsistent. How could something which is of “infinite density”
    possibly have “zero size”? How could these possibly even exist separately, with
    only one concept at a time? Or even way more impossible, each at the same time?

    The Big Bang Theory was originally derived from Lemaitre. His view of how the
    universe could have started was quite different from what eventually evolved into
    the Big Bang as we know it today.

    What I’ve read from more recent sources elsewhere often isn’t as accurate as what is
    found in various older books. The original hypothesis Lemaitre had thought of was that
    the universe started out as the primeval atom or cosmic egg, which would split or divide
    itself, similar to how the amoeba multiplies, until various celestial objects, stars, planets,
    and such, were created to eventually harbor various kinds of life-forms.

    When first hearing about this, Einstein didn’t think much of the idea, even though
    he had been known to say that the universe is either expanding or contracting.
    However, he pictured these terms in a much different way when he had first thought
    about them. He theorized this since he pictured that a “static” universe and all the
    physical objects it contains, would inevitably collapse into each other from the effect
    of their own gravity. He had the idea of a sort of “anti-gravity” that “pushes” outward
    from various celestial objects at a distance, to prevent the universe from collapsing.
    He called this the Cosmological Constant.

    At that time, Einstein and literally everyone else in the world didn’t have any idea of
    a colossal explosion or a literal “beginning” of the universe, from the initial singularity,
    which sent mass and energy rushing out in all directions.

    It wasn’t until Hubble’s Law, with viewing the universe from outer space, and seeing
    how everything appeared to “rush apart” from everything else, that the Big Bang,
    as we know it today, originated. Since the time that the Red Shift and the Cosmic
    Microwave Radiation were observed, though possibly interpreted mistakenly, that
    the Big Bang has been the most highly accepted cosmological theory for decades.
    Actually, even Einstein eventually accepted it, and of course, considered his idea
    of the Cosmological Constant, as he later famously stated, his “greatest blunder”.

    The “updated” version of the Big Bang had immediate problems and inconsistencies
    of which to account. For instance, according to the Big Bang, there was once a “time”
    when mass and energy, and even time and space, didn’t exist. Such a state seems
    completely impossible to even conceive of.

    There was supposedly nothing at all that previously existed “before”. That there literally
    wasn’t a “before” at all. The way the theory goes is that suddenly the tiny pinpoint, much
    smaller than an atom, appeared from “out of nowhere”, to immediately explode and create
    the expanding universe. What could have caused the pinpoint to suddenly appear? and
    what caused it to explode?

    If there was a beginning to the universe, and that the “initial singularity” did appear from
    out of nothing, how much time was there between the spontaneous appearance and the
    spontaneous explosion? Was the amount of time quicker than a microsecond? Maybe
    a year? Or did the pinpoint stay there dormant for countless millennia? Or what if
    the explosion occurred within a universe that already existed?
