Modern supercars are incredibly impressive and quick vehicles, and a lot of that comes down to the physics behind their increasingly complex designs.

Speed alone may be the factor that draws many sports fans to the bobsled, luge and skeleton events at this year's Beijing Winter Olympics. But beneath the thrilling descents of the winding, ...

Plasma physics is the study of charged particles and fluids interacting with self-consistent electric and magnetic fields. It is a basic research discipline that has many different areas of ...

Traveling at light speed is not just difficult—it violates the rules that govern mass, energy, and motion. This breakdown ...

The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space. The ...

Semiconductor electronics is getting faster and faster - but at some point, physics no longer permits any increase. The speed can definitely not be increased beyond one petahertz (one million ...

Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...
