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 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 ...

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 ...

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum mechanics. At the beginning of time and the center of every black hole lies a ...

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 ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

Scientists in Wales have built the world’s most sensitive table-top interferometer, which is a miniature, ultra-precise instrument capable of measuring distortions in space-time smaller than a ...
