The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

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 ...

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

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...
