With a clever design, researchers have solved eddy-current damping in macroscopic levitating systems, paving the way for a ...

Emergent gravity is a bold idea. It claims that the force of gravity is a mere illusion, more akin to friction or heat—a property that emerges from some deeper physical interaction. This emergent ...

Researchers have proven that when bodies exist in curved spaces, they can in fact move without pushing against something. When humans, animals, and machines move throughout the world, they always push ...

The new levitating rotor works because of its rotational symmetry. Unlike plates that move up and down in varying magnetic fields, the spinning rotor stays within a constant magnetic flux. This ...

When Isaac Newton inscribed onto parchment his now-famed laws of motion in 1687, he could have only hoped we'd be discussing them three centuries later. Writing in Latin, Newton outlined three ...

Firing a gun in space plays out very differently from that on Earth due to some bizarre physics. Here's everything that occurs when you pull the trigger.
