In 1974, physicist Stephen Hawking described the potential for tiny, primordial black holes that existed at the dawn of time ...

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 ...

In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally explains how this "forbidden" black hole came to be, and what it can teach ...

An eon ago, when only microbes dwelled on Earth, a pair of black holes some 1.3 billion light-years beyond the solar system spiraled toward each other until they crashed. The two became one big black ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration imagines GW250114, a powerful collision between two black holes observed in gravitational waves by the LIGO ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

The discovery of a hidden supermassive black hole inside an ancient galaxy suggests that some of our universe's most extreme objects could be invisible unless observed in infrared wavelengths, James ...

On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole. Parallels in the physics of the universe and that of black holes have led ...
