Basically, it is impossible for big bang to have a cause, because, theoretically speaking, time, space and matter all started to exist from big bang. And by the law of causality, the cause of an effect always comes before the effect. Therefore, if big bang is the effect, then the cause is before the big bang, and as there is nothing before the big bang, it is impossible for big bang to have a cause. Therefore, logically speaking, as there is no reason for big bang, and therefore, there is no reason for anything. Now, I know I am delving into Philosophy here and getting distracted from Pure Science, but that is what logic leads me to. I am happy for any feedback,
"Basically", it is a scientific -- and a mathematical -- fact that the Big Bang can have a cause. It is a physical impossibility to observe the infinite (the antonym of finite), but never-the-less the existence of the infinite will have influence and consequences (will have '
presence'), as finite physics' facts and potential of the infinite, regarding this finite side (and these finite sides (this infinite self-mirrors to infinity -- it cancels but does not cease to exist)), the only finite side(s) of the infinite (Stephen Hawking: The particle has six faces; six individualized dimensions; therefore is in fact six individualized particles; but never-the-less is exactly one particle).
That "
presence" is a single-sided 2-dimensionally flat frame entity of entities, a severally dimensioned (multi-dimensional) collapsed horizon, aka ['Big Bang' / 'Planck' / 'c' / '?'}, the infinite Universe (U) the [Big Crunch / Big Hole binary (0 and/or 1) 'naked singularity'] of Vortex effectively (relatively), but not at all really, closed up to it on its non-local, non-relative, non-existent, side, so to speak (I, for one, would not care to call it any kind of one dimensionality, though that point -- blackhole and/or wormhole -- is one property of 'binary' 3-dimensionality (binary "and/or" is in fact, at the very least, three dimensions)).
The cause of Big Bang, reduced to its simplest dimensional representation, is the never changing, never to be changed, difference (and thus [horizon's] ultimate boundarylessness) between "finite" and "infinite," each being a form of nemesis regarding the other -- though neither can exist without the other. It is just a matter of "what, where, when, and how." You can argue theory all you want , but this difference, and the physical manifestation in whatever "difference," is very "basic" reality. The Big Bang+ is manifestation of a difference, the biggest difference of all (between infinite and finite). And it is very useful dimensionality since "finite" is, obviously, finite. A problem solved by infinities of finites (conversions to and from infinities of point infinitesimals, the infinite of the point infinitesimal. Infinite does not explode to finite, it mirrors to finite(s). And, as I said, "finite" is, obviously, finite (change). A finite universe is a demolition derby heading into disappearance from beginning to end, generation to generation, plane to plane, past>future (+) always paralleling, always correlative with, future>past (-), and the two correlative with '0' (0-point).
The Big Crunch (Big Hole) / Big Hole (Big Crunch) Vortex is the infinite. There is no other side to infinite. And as far as "finite" is concerned, the collapsed horizon of "infinite" is single-sided (only ONE-sided!) 2-dimensional 'flat' frame physical entity, a white hole as opposed to black hole, so to speak. A black hole is also a single-sided (only ONE-sided) 2-dimensional "flat' frame physical entity. Two single-sided 2-dimensional 'flat' frame doors of universe (u), one marked "Entrance Only". The other marked "Exit Only."
