The idea of recreating a black hole might sound technically impossible. However, 30 years ago William Unruh suggested that ¨the same arguments leading to black-hole evaporation also predict that a thermal spectrum of sound waves should be given out from the sonic horizon in transsonic fluid flow". In the lab, the production of quantized sound waves in a Bose-Einstein Condensate (BEC) is the equivalent to what it happens at the event horizon of a black hole.
Various possible experimental realizations were presented some years ago (LINK). Nonetheless, there has not been any agreement in the scientific community about this correlation between black holes and BECs, i.e. between general relativity and quantum mechanics.
This year Jeff Steinhauer in Israel has provided a different result, and it appears to verify Hawking's calculations (clik on the image below to know more).
Quantum gravity could be getting closer to a proven theory.
