Light's behavior seems counterintuitive. That is, until you figure out light is a wave. The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you ...

There has been a lot of digital ink spilled over the recent paper on the reactionless thrust device known as the EMDrive. While it's clear that a working EM Drive would violate well established ...

The universe occasionally produces a huge surprise that proves physicists wrong, says Kip Thorne, who grew up in Logan, Utah, ...

A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to ...

According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real? When you purchase through ...

Quantum mechanics is baffling. On the atomic and subatomic scale, matter seems to behave in ways that we, in the macro world, would generally think of as impossible. Particles can exist in two ...

Einstein desperately wanted a unified theory of physics. Thanks to gravitational waves—the poster child of general relativity—his wish might just come true. Gravitational waves are ripples in the ...

In some interpretations of quantum mechanics, such as the Many-Worlds interpretation or the Pilot Wave Theory, parallel universes may form every time a subatomic particle goes through any interaction.

When I began my master’s program in cognitive science, an electrical engineering professor told us—rather arrogantly—that the soul is nothing but neurons firing. “You’re deluded if you think otherwise ...

For the first time, researchers have performed a version of the famous double-slit experiment with antimatter particles. The double-slit experiment demonstrates one of the fundamental tenets of ...
