Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

That's one-tenth the speed of light, according to a study published in Physical Review Letters. The discovery could reveal brand new laws of physics, one expert said. Scientists have calculated a ...

The skintight suits skiers wear are not for aesthetics; they help control the physics of air. Loose fabric increases drag and ...

Every generation grows up with starships that jump across galaxies in a heartbeat, but the real universe is far less forgiving than the screen. The same physics that lets GPS satellites work and ...

On one hand, the speed of light is just a number: 299,792,458 meters per second. And on the other, it’s one of the most important constants that appears in nature and defines the relationship of ...
