Cosmologists have long treated black holes and the Big Bang as separate extremes of physics, one swallowing light, the other birthing space and time. A provocative line of research now suggests those ...

“We’re not claiming that it’s absolutely going to happen this decade. But there could be a 90% chance that it does." Reading time 2 minutes It’s been a fantastic week for Stephen Hawking’s black hole ...

The JWST has detected more active black holes than expected, casting doubt on their prevalence in the early universe.

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

While nearly all massive galaxies possess central black holes, the presence of such black holes in dwarf galaxies remains an open question, with previous estimates identifying them in only 0.5% of ...

Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much ...

In May 2019, astronomers picked up something strange in the fabric of spacetime. The LIGO and Virgo detectors recorded a gravitational wave that lasted just one-tenth of a second. The signal, known as ...

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when all of space, time, and energy were born from a single infinitely dense ...
