Crystals of space and time: A structural phenomenon that may collapse into tiny black holes
May 2026, phys.org
Space and time can form a kind of "crystal" that may turn into a black hole. ... When spacetime organizes itself into a regular, crystal-like structure during a process known as critical collapse. Black holes usually form in spectacular events, such as the death of a massive star. But in theory, arbitrarily small black holes are also possible: tiny microscopic objects that can emerge from special critical states after the slightest addition of energy.
Wait
"This spacetime crystal is a very peculiar and fascinating object," says Grumiller. "It is a kind of intermediate state, an unstable point that can evolve in two different directions. It may simply dissolve again, leaving behind ordinary spacetime filled with freely moving particles. But if a tiny amount of energy is added, the evolution takes a completely different path: the inconspicuous spacetime crystal turns into a black hole."
Not done yet
"Our universe has four dimensions—three dimensions of space and one dimension of time," explains Christian Ecker. "But in principle, nothing prevents us from writing down physical equations for a larger number of dimensions—five dimensions, forty-two dimensions, or even infinitely many."
