For example, he considers the idea that the Big Bang was the beginning to be a myth:
5.) Space, time, and the laws of physics did not exist prior to the Big Bang. If you had reached a true singularity, or a place where you reached infinite densities and temperatures, the laws of physics would break down. In General Relativity, singularities are where spacetime can either enter or exit existence, and without spacetime, there are not even necessarily rules that govern the physical Universe that could exist within it.
But those laws must certainly have existed during the inflationary phase that set up the Big Bang itself. With the knowledge we have of inflation, and the observational confirmation of its predictions, however, new questions arise …
We don’t have sufficient information in our observable Universe to know whether time is finite or infinite; whether it’s cyclical or linear. But even before the Big Bang, we can be certain that space, time, and the laws of physics themselves definitely existed.
That’s 5 common Big Bang misconceptions, all thoroughly dispelled.Ethan Siegel, “Don’t Believe These 5 Myths About The Big Bang” at Forbes
Siegel doesn’t really explain why we can be sure that space, time, and the laws of physics preexisted the Big Bang; the idea that they pre-existed has the effect of untethering them from the tiresome demand for evidence. But might that be part of the charm of the idea.
