einsteinium99 Posted June 20, 2023 Posted June 20, 2023 What happens if, instead of considering the singularity as a "point", we consider it as a gravitational wave with no upwards limit to its frequency? In this understanding although the Universe appears to expand from a point, the expansion of the Universe and thus the progression of time is explained in terms of a pervasive gravitational wave in spacetime with no upwards or downwards limit to its frequency. At a certain frequency, this wave due to the limitations of human observation would be indistinguishable from a point, but nevertheless capable of increasing in frequency to no end. The singularity is a wave of ultra-high frequency that underlies all of spacetime, but is only noticeable under certain conditions such as preceding the Big Bang or at the heart of a black hole. The observable universe consists of spacetime within the visible spectrum of spacetime (commensurate with the visible spectrum of light). Spacetime beyond the event horizon of a black hole would be ultra-low frequency spacetime as spacetime is stretched towards the ultra-high frequency singularity under conditions of massive amounts of gravity. I.e., spacetime "redshifts" towards the singularity, from the downwards limit in the visible spectrum of spacetime (in terms of frequency), which we call the "event horizon".

If the singularity were real, the whole universe is contained within it. There is no 'outside'. If you conceive of an 'outside', then what does that reside in? It's a "Turtles all the way down" infinite regression argument. Edited June 20, 2023 by StringJunky
Genady Posted June 20, 2023 Posted June 20, 2023 Singularity is a consequence of GR. Gravitational wave is a consequence of GR. In GR, singularity is NOT a gravitational wave. If you want to consider a singularity as a gravitational wave, then either the singularity or the gravitational wave (or both) should be NOT what they are in GR, but something else. What are they? 1

Einstein could not make heads or tails of the singularity. This is why: to resolve the singularity as a point in spacetime is objectively incorrect.

Whatever idea you concoct based on this is built on sand. Does it or does it not appear according to modern scientific theory that the Universe emerged from a point in what we call "The Big Bang"? What I am suggesting is that a wave in spacetime increasing indefinitely in frequency, would be virtually indistinguishable from a point due to the intrinsic limitations of human observation.

Where are we? In the universe. At what was called the Inflationary Period/Big Bang, distances increased exponentially between masses. The space increased in-between masses, they didn't eject from a singular point in the ring pattern of a typical explosion. It was a big expansion, not a big explosion.
