HOLY SUPPOSITIONS BATMAN!
Science can't see back to the BB, look it up. Because as a pretend scientist, you don't even know that yet.
Can't see back to?! Look it up?!
The only pretender here is you.
The CMB is the cosmological snapshot of the Big Band. The Big Bang is precisely the point back to which we may confidently trace the history of the Universe. It's
before the Big Bang state, i.e.,
before cosmic inflation that things get hazy . . . because (1) we don't know precisely how cosmic inflation was caused and (2) the calculi of general relativity ultimately yield a singularity (an infinite point of density).
I don't need to look it up.
Excerpt from an article I WROTE:
Learned theist apologists . . . are well-aware of the "cosmic problems" with the Big Bang model, albeit, relative to Guth's transitional phase of cosmic inflation per the break in the symmetry of the grand unification. These problems are (1) the magnetic monopole problem, (2) the flatness problem, and (3) the horizon problem. But we're confident that the first principles of ontology and epistemology will continue to hold whether the universe began as an "infinite point of density" or as a rapid, exponential expansion of space (cosmic inflation) driven by quantum fluctuations in the underlying field, which set up the dense, uniform state of high-energy matter (quark-gluon plasma) and radiation—namely, the Big Bang state. The explanatory power of the Big Bang model goes to the cogency of its description of the development of the universe beginning at the inflationary epoch, followed by the quark epoch, then, eventually, onto primordial nucleosynthesis and stellar nucleosynthesis in the expanding universe.
For those who may still be confused about the actual sequence of events in the current understanding of the Big Bang scenario. . . .
The ostensible singularity of the original model is a relic of the calculi of general relativity sans the factor of cosmic inflation. The widely disseminated notion of a singularity and graphs depicting the same are arguably dated, but one should not be too dogmatic about this given that an initial moment of cosmic inflation being the beginning of our universe instead of a point of infinite density ultimately goes to a theoretical gap. The Big Bang state, which we know emerged for sure, requires cosmic inflation. Extrapolating backwards from the current state of our expanding universe—as space shrinks, as the material of the universe is squeezed into an ever smaller volume—the known laws of physics, specifically, the calculi of general relativity, yield a singularity just before a period of high-density and -heat (i.e., the period of the Big Bang). In other words, according to inflationary theory, our universe didn't begin as an arbitrary bang of matter and energy. Rather, all the energy of the universe was bound up in the fabric of space itself. This vacuum energy caused the universe to expand at a rapid, exponential rate and stretched the quantum fluctuations of the underlying field across the early universe, creating comparatively near-uniform regions of energy density. After the inflationary epoch, the early universe cooled enough for most of this energy to convert into a hot, dense state of matter and radiation. Hence, "the explosion" was actually cosmic inflation, which put the "bang" in the Big Bang that was actually just a big conversion of energy.
The reason you still routinely encounter papers written by scientists and articles written by science journalists that refer to cosmic inflation as something that happened after the Big Bang is because we still don't have a scientifically demonstrable explanation for what caused inflation in the first place. Cosmic inflation beautifully harmonizes with the Big Bang model and, thusly, makes it whole. But cosmic inflation does not account for itself, and, once again, the calculi of general relativity extrapolate backwards to a singularity, where the known laws of physics breakdown. Bottom line: in lieu of a demonstrable scientific explanation for what actually lit the fuse in the first place, scientists are hedging their bets. The desire to avoid dogmatism in this wise is commendable, but it nevertheless serves to confuse the theoretical order of things in the minds of many regarding the prevailing synthesis of inflationary theory and the Big Bang model.
