For most of the past century, wormholes sat comfortably in the realm of science fiction, a mathematical curiosity that let ...

A new mathematical model of a wormhole suggests that two black holes can be “cut and pasted.” Cut and paste is an official concept in math, referring to two surfaces that may be transposable. In this ...

In 2019, LIGO and Virgo recorded something truly bizarre – a gravitational wave event less than a tenth of a second in duration. Compared to the drawn-out chirps of black hole binaries on decaying ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been ...

Here’s what you’ll learn when you read this story: Theoretical physicists have long debated the possible existence of wormholes, which are mathematically possible, but no evidence points to their ...

What: New analyses using early observations from the European Space Agency’s Euclid mission examine how galaxy mergers trigger active galactic nuclei (AGN), luminou ...

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 ...

Imagine two towns on two opposite sides of a mountain. People from these towns would probably have to travel all the way around the mountain to visit one another. But, if they wanted to get there ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...
