Spacetime 'Echoes' From Quantum Black Holes Could Soon Change Physics Forever

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 take more observations and research to be sure.

These signals, assuming they exist, would be created by close interactions with black holes, and they could help scientists confirm whether matter that enters black holes is truly gone forever.


“This is a very exciting area of research,” said study co-author Niayesh Afshordi, an astrophysicist at the University of Waterloo, in a call. “It touches on cornerstones of physics and science as we know it.”

A confirmed detection of the echoes would be a “smoking-gun sign of new physics,” said Vitor Cardoso, a physicist at the Instituto Superior Técnico in Lisbon, Portugal, in an email.

I'm not a physicist nor do I play one on TV, but this stuff just fascinates the hell out of me.

part of the article eludes to what happens to the matter that a black hole sucks up.

maybe, the end of the universe is just one giant black hole that has sucked everything up, then does something beyond my pay grade to understand or even ponder, explodes and starts a new universe again.
