I thought your claim was that scientists had posseted some kind of history before the big bang. This looks more like their speculation about what took place in the singularity. I of course grant the proposition that the universe began in a singularity event. This occurred between T=0 and T = 10^-47. No one knows what happened during this time because the laws we use to investigate things do not work in that period of time. The first fraction of a second is a mystery, the link you provided must be theories and evidence about what that first tiny flash that created the universe was like. I doubt they have any idea but even if they do it would not affect my point, that being that the universe INCLUDING the singularity began to exist a finite time ago. That is what the evidence shows and I mean all the evidence. Any theory about what happened before time, matter, and space began to exist in the singularity event is not supported by any meaningful evidence. IOW the dominant model of a finite universe that began a finite time ago is unaffected by whatever occurred in the first fractions of a second, even if we did know what had occurred, which we don't.
The absolute origin of the universe, of all matter and energy, even of physical space and time themselves, in the Big Bang singularity contradicts the perennial naturalistic assumption that the universe has always existed. One after another, models designed to avert the initial cosmological singularity--the Steady State model, the Oscillating model, Vacuum Fluctuation models--have come and gone. Current quantum gravity models, such as the Hartle-Hawking model and the Vilenkin model, must appeal to the physically unintelligible and metaphysically dubious device of "imaginary time" to avoid the universe's beginning. The contingency implied by an absolute beginning ex nihilo points to a transcendent cause of the universe beyond space and time. Philosophical objections to a cause of the universe fail to carry conviction.

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,
An initial cosmological singularity . . . forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity. . . . On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.

The popular expression "Big Bang," originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no "outside," just as there is no "before" with respect to the Big Bang).

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,--and this deserves underscoring--the origin it posits is an absolute origin
ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize,
"At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation
ex nihilo." On such a model the universe originates
ex nihilo in the sense that at the initial singularity it is true that
There is no earlier space-time point or it is false that Something existed prior to the singularity

12 As Gott, Gunn, Schramm, and Tinsley write,
"the universe began from a state of infinite density about one Hubble time ago. Space and time were created in that event and so was all the matter in the universe. It is not meaningful to ask what happened before the big bang; it is somewhat like asking what is north of the North Pole. Similarly, it is not sensible to ask where the big bang took place. The point-universe was not an object isolated in space; it was the entire universe, and so the only answer can be that the big bang happened everywhere" (J. Richard Gott III, James E. Gunn, David N. Schramm, and Beatrice M. Tinsley, "Will the Universe Expand Forever?"
