Is the Big Bang the least popular widely accepted science theory? Theoretical astrophysicist Ethan Siegel wishes it out of existence by positing a cosmic inflation that wipes out all possibility of knowledge:
Lastly, and perhaps most importantly, we can no longer speak with any sort of knowledge or confidence as to how — or even whether — the universe itself began. By the very nature of inflation, it wipes out any information that came before the final few moments: where it ended and gave rise to our hot Big Bang. Inflation could have gone on for an eternity, it could have been preceded by some other nonsingular phase, or it could have been preceded by a phase that did emerge from a singularity. Until the day comes where we discover how to extract more information from the universe than presently seems possible, we have no choice but to face our ignorance. The Big Bang still happened a very long time ago, but it wasn’t the beginning we once supposed it to be.
Ethan Siegel, “Surprise: the Big Bang isn’t the beginning of the universe anymore” at Big Think (October 13, 2021)
Translated from the Popular Science, this seems to mean “Better all information gets wiped out than that the Big Bang be some kind of a beginning.”
Earlier this year, Siegel was wondering why so few challenge the Big Bang.
