For decades, astronomers have been puzzled by strange “zebra stripe” patterns in radio waves from the Crab Pulsar — bright bands separated by complete darkness. Now, new research suggests the answer ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

The study of higher dimensional gravity theories represents a vibrant and innovative field in modern theoretical physics. At its core, this research seeks to extend the familiar four-dimensional ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

1078 years is still an absurdly long time, but in modern cosmology it counts as a dramatic revision. A recent theoretical ...

How to build a particle collider the size of the solar system. To observe the quantum nature of gravity and of spacetime itself, we need a particle collider the size of the solar system. Or we could ...

Entropy. The word itself should cause insomnia. It means that matter and energy will degrade—ultimately leading to chaos in the universe—if things are left alone. So why is a new theory suggesting ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...
