Quantum tornado' allows scientists to mimic a black hole on Earth

[Admin]

Scientists created a giant vortex made of tiny quantum parts in a helium superfluid just a few degrees above absolute zero. This "quantum tornado" helped them to bring black hole physics down to Earth.

That adds to the experiments studying Hawking radiation with similar mimics.

Black holes aren't actually objects, but are regions of spacetime created by an infinitely dense and compact mass — a central singularity where the very laws of physics break down.

Black holes are considered gravitationally compressed objects (obey thermodynamics by Hawking emission), but they are not necessarily containing singularities. In fact, a recent paper by Kerr himself seems to have found a flaw in black hole singularity claims, adding to the flaw that cosmologist Davies et al. found in cosmology singularity claims.
