A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

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 world's most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run. The Quantum Enhanced ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

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 ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

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 ...

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 ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
