Machine learning helped show how harnessing the weird effects of Einstein’s special relativity could enable a new kind of ...

Quantum ideas describe particles and fields in tiny packages, but general relativity paints gravity as smooth curves in space ...

Although our universe is mostly normal matter, antimatter isn’t so hard to create — supernovae, black holes, and even bananas ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity ...

Dear Sir, After viewing David Tennant's new game show, I feel obliged to revise my theory of special relativity. It appears I ...

A trip through time has always sparked curiosity. The idea that you could step into a machine and emerge in the past or ...

ABSTRACT: “All is Number”—the universe follows a few profound mathematical rules, and pure thought can grasp reality. This paper explores the first principles of fundamental physics, focusing on the ...

In 1905, Einstein linked space and time, showing that motion through one affects passage through the other, the hallmark of his special theory of relativity. Ten years later, Einstein extended ...

When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer ...
