Gravitational Waves Should Permanently Distort Space-Time

By Katie McCormick

The “gravitational memory effect” predicts that a passing gravitational wave should forever alter the structure of space-time. Physicists have linked the phenomenon to fundamental cosmic symmetries and a potential solution to the black hole information paradox.

In Violation of Einstein, Black Holes Might Have ‘Hair’

By Jonathan O'Callaghan
