Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

A conspiracy theory that spread on social media claims that gravity will disappear for seven seconds this August, and that NASA is aware that this will happen. A physics professor explains why this is ...

During the survey, researchers identified a promising 8.19-millisecond pulsar (MSP) candidate located close to Sagittarius A*, the supermassive black hole at the center of our galaxy.

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast ...

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 ...

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 ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

What if gravity isn’t weirdly quantum at all, but rather … just a bit messy? The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

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 ...
