The pair merged to create a single hole about 225 times the mass of the sun.

At 225 solar masses, this gargantuan merger of two black holes challenges our thinking on these famously elusive objects.

"The biggest surprise of all was that the black hole was not located inside either of the two nuclei but in the middle. We ...

The massive black hole has been dubbed GW231123. Its unusual size and behavior is challenging scientists' understanding of ...

Astronomers have detected the most massive black hole merger ever observed, challenging stellar evolution and black hole ...

If our universe is one of many born from black holes, perhaps the parameters are simply a result of the unique conditions within our parent black hole, rather than an improbable cosmic coincidence.

For decades, astronomers have theorized that black holes fall into three broad categories. There are the stellar-mass black holes, which range from five to 50 times the mass of our Sun. Then ...

A radical hypothesis suggesting black holes could be behind the accelerating expansion of our universe has been stirring up controversy among astronomers. A new study may contain the first ...

This new research gives credence to a theory that posits our galaxy is inside of a black hole, which in turn is located inside another, bigger parent universe. Getty According to Space.com, this ...

Dark matter may have contributed to the formation of giant black holes in the early universe, researchers propose in a new paper. More observations, especially with the James Webb Space Telescope ...

A radical new theory suggests our universe didn’t begin with the Big Bang. It bounced out of a black hole inside a much older cosmos.

For decades, astronomers have theorized that black holes fall into three broad categories. There are the stellar-mass black holes, which range from five to 50 times the mass of our Sun. Then ...
