Spacetime ‘Echoes’ From Quantum Black Holes Could Soon Change Physics Forever

By Becky Ferreira A key mystery about black holes might be resolved by eerie “echoes” in spacetime, which could unlock an entirely new branch of exotic physics if they are ever detected. In fact, the echoes may have already been detected, according to a recent study published in the Journal of Cosmology and Astroparticle Physics, though it will …
