Wouldn’t a singularity be the smallest point possible? By definition it is pretty much a cyclone of the smallest units of space time fabric. Any particle would need to exist above this scale in order to exist within the construct of the universe. If there were any object smaller than this it would mean that whatever makes up a unit/point/pixel of space time fabric is actually an emergent construct of much smaller units. If there were smaller said units composing even space time itself, perhaps these would be or be composed by a finally irreducibly small unit, the properties of which give rise to all variations of matter/energy, the laws which govern them and their equality and convertablity according to special relativity.
- cdumler 5y agoMost scientists do not think that black holes have a "real singularity." The idea of a mass that occupies a single point in space comes from taking Einstein's equations beyond the event horizon, ie. the curvature of space is greater than light so means nothing can have any resistance to distance/size. At some point between the event horizon and the center, quantum gravity (which is not understood) has to come into the picture. One idea is the "black hole firewall," which is that mass gets "stuck" at the boundary of the black hole.

Do the CMB or GWB indicate that the Shapley Attractor / Great Attractor interaction is the omnidirectional mouth / center of it all, or no? https://en.wikipedia.org/wiki/Shapley_Supercluster https://en.wikipedia.org/wiki/Shapley_Supercluster Gravitational wave background > Cosmological sources https://en.wikipedia.org/wiki/Gravitational_wave_background https://en.wikipedia.org/wiki/Gravitational_wave_background ... FWIU, all we've done is observe minute confirmatory fluctuations from the ground; e.g. LIGO (Nobel Prize in Physics 2017, Thorne, NumFocus-supported tools)? Could that tell us where the center is? Should there even be one if we're actually inside a white hole / black hole combo? What "dark matter" do we subtract or add to the CMB, GWB,? ...
