In 1974, physicist Stephen Hawking described the potential for tiny, primordial black holes that existed at the dawn of time to explode — and reshaped what we knew about these cosmic behemoths.

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 ...

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 ...

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 ...

Seventeen miles of underground tunnel, thousands of superconducting magnets, and protons whipped to a fraction below light speed have given the Large Hadron Collider a reputation that borders on myth.

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 ...

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 ...

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 ...

In a significant potential shift for astrophysics, it turns out that some quasars may weigh as little as half what was previously believed. Share on Facebook (opens in a new window) Share on X (opens ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. A never-before-seen blast from a supermassive black hole was ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or mathematician to tell you about fascinating ideas from their corner of the ...
