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 ...

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 ...

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.

The black hole universe also offers a new perspective on our place in the cosmos. In this framework, our entire observable universe lies inside the interior of a black hole formed in some larger ...
