Twin Black Hole Collisions Offer the Most Precise Test of Einstein’s Theory Yet
(scitechdaily.com)
Two recently detected black hole mergers, observed just a month apart in late 2024, have given scientists their most precise test yet of Einstein’s general relativity. The twin collisions, recorded by the LIGO-Virgo-KAGRA Collaboration, revealed one of the fastest-spinning black holes ever observed ...
Black holes, once thought to be unknowable, are now under close scrutiny thanks to the Event Horizon Telescope’s groundbreaking images. Scientists have used these observations to explore whether Einstein’s general relativity truly holds up under extreme conditions. By comparing simulated “shadow” im...
“Cannibal Stars” and Black Holes May Have Formed in the Universe’s First Second
(scitechdaily.com)
A new study suggests that during a potential phase of primordial matter domination, particle interactions may have led to the formation of the universe’s first compact cosmic objects. Less than a second after the Big Bang, before the first atoms existed, tiny particles may have clustered into halos ...
Fresh observations of two merging black holes confirm predictions made by Stephen Hawking based on Albert Einstein’s theory. A decade after the first detection of gravitational waves from two merging black holes, the LIGO-Virgo-KAGRA collaboration, including Columbia University astronomer Maximilian...
