This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. In the fall of 1915, the foundations of physics ...

The quantum physicists Sandu Popescu, Yakir Aharonov and Daniel Rohrlich have been troubled by the same scenario for three decades. It started when they wrote about a surprising wave phenomenon called ...

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics experiments that changed the world. When you purchase through links on our site ...

Are black holes tunnels to other locations in spacetime? Are they wormholes connecting different regions of the universe? A study has provided a clear answer to this question. The remainder of this ...
