The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

In this last part of our series on recently digitized books from the Wenner Collection, we are focusing on works that ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

The breakthrough could suggest a way to study 'quantum gravity,' the missing link between quantum physics and Einstein's general relativity in the lab. When you purchase through links on our site, we ...

If the universe was a soundtrack, we have been humming it our whole life. Every atom in our body, every star in the sky, every beam of light is part of a piece of music that never stops playing.

HERE is a readable book, excellently translated, for which we have again to thank Mr. H. L. Brose. Though it is called an introduction to the theory of relativity and gravitation, it is more strictly ...

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.

You may think of physics as a way to explain the behaviors of things like black holes, colliding particles, falling apples, and quantum computers. But a small group physicists today is working on a ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...
