The idea that the universe is (or is not) spatiotemporally infinite has been the subject of active debate.
The question of what happened before the ‘beginning’ has very often been shrugged off as irrelevant, as it is often speculated that there was no time or space to even think about.
In the language of geometry, the void is a spacetime that contains no points: i.e., there is no spacetime, no language of geometry.
It would characterize absolutely “nothing.”
The ‘nothingness’ prior to the creation of the universe is considered (by several specialists) as the most complete void imaginable—
no space, no time, no matter, no radiation, no light, no darkness, no temperature, no dimensions, no size, no vacuum, no energy, no pressure, no force, no particles, no fluctuation, no density, no mass, no general relativity, no quantum mechanics, no thermodynamics, no laws of nature, no order, no disorder, no universe, no God, no organizing Wit, and no Astrophysical Journals—the empty set—as referred to by mathematicians.
Because all scientific theories are formulated on a spacetime manifold, all explosion theories break down before the colossal creation (destruction) event,
ab irato.
Hence, because of the impossibility to predict any events before time t = 0, they are simply cut out of the theories; swept under the carpet.
With the clock ticking from Ground Zero onward (an epoch nearly resembling a scene out of Dante’s Inferno), the spacescape seems somewhat standard in comparison with whatever was (or wasn’t) before.
That’s the surface picture. Beneath the surface, there is a difference between normalcy and the appearance of normalcy.
