"Creating Record-Breaking Quantum Vortex to Simulate Black Holes"

Physicists have created a giant quantum vortex inside supercooled liquid helium to mimic the behavior of rotating black holes, aiming to gain insight into the enigmatic nature of these cosmic phenomena. By observing the vortex's resemblance to black hole behavior, including the phenomenon of ringdown, researchers hope to eventually predict how quantum fields behave in the vicinity of astrophysical black holes.
