Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

The ice in a domestic freezer is remarkably different from the single crystals that form in snow clouds, or even those formed ...

An obscure theory of elementary particles proved to be key to China’s re-emergence as a scientific nation after the Cultural ...

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 ...
