The LIGO Hanford Observatory near the Tri-Cities and its twin in Louisiana detected ripples of time and space passing through ...

When black holes merge, what happens inside of them is anybody's guess.

Black holes are among the most enigmatic and fascinating objects in the universe. Their sheer existence challenges our understanding of the cosmos and raises deep questions about the nature of reality ...

“This was our first evidence that black hole binaries do overcome the final-parsec problem,” said Laura Blecha, an astrophysicist at the University of Florida. So how do they do it?

The research is described in "Self-interacting dark matter solves the final parsec problem of supermassive black hole mergers," published this month in the journal Physical Review Letters.

As black holes slowly vanish through Hawking radiation, their information may be preserved in subtle space-time ripples, a new theory suggests.
