In 1916, only a year after Albert Einstein had published his general theory of relativity, Karl Schwarzschild used mathematical calculations to show this: If sufficient mass could be placed into an ...

If physicists had a holy grail it would go by the name of Quantum Gravity. For 60 years researchers have been searching for a way to unite the very large and the very small into a single coherent ...

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 ...

Chinese researchers are poring over a puzzling gravitational wave signal that appears to defy the standard script of black hole collisions, reviving one of physics’ most audacious possibilities: that ...

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

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 ...

Here’s what you’ll learn when you read this story: A wormhole in nature (for select values of “nature,” of course) might be a similarly higher-dimensional shape that does not act the same when ...
