IMHO, there cannot be such objects as singularities (0 size & infinite density) in the real universe! Everything should/must be made of particles (including black holes)! & if black holes should/must be made of particles, then there is only 1 realistic possibility: Planck particle! (No other real/theoretical particle can be a realistic possibility, because it should/must be a particle that is itself (like) a tiny black hole! (For example, consider how a neutron star is really like a giant neutron, because it is made of neutrons!)) (& it should/must be a particle that cannot be crashed/destroyed in a BH because it already has min size & max density physically possible!)
From Wikipedia:
"A Planck particle, or planckion, named after physicist Max Planck, is a hypothetical particle defined as a tiny black hole whose Compton wavelength is equal to its Schwarzschild radius. Its mass is thus approximately the Planck mass, and its Compton wavelength and Schwarzschild radius are about the Planck length."
Of course, the huge questions is how this idea can be proven or disproven?!
Maybe gravitational waves are discrete in units of Planck mass/energy?
(& if so then someday it maybe possible to detect this, when sensitivity/resolution of GW detectors are good enough!)
