Physicists have started to treat a once-fringe idea with surprising seriousness: that our entire observable universe might be the interior of a black hole that formed in some larger cosmos. The notion ...

A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA's Chandra X-ray Observatory may help explain how some black holes can ...

Just 500 million years after the Big Bang, a colossal black hole, 300 million times the mass of the Sun, was already blazing at the heart of a tiny, brilliant galaxy. Found with JWST, this discovery ...

In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...
