In the context of this article, "faster-than-light" means the transmission of information or matter faster than c, a constant equal to the speed of light in vacuum, which is 299,792,458 m/s (by definition of the metre) [ 3] or about 186,282.397 miles per second. This is not quite the same as traveling faster than light, since:
The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour). [Note 3] According to the special theory of relativity, c is the upper limit for the speed at which ...
Don't do it if it hurts. After exercise, “light stretching is OK, as long as you don't reach a point where you're feeling pain,” Behm said. Since your muscles will be warm by that point ...
No-communication theorem. In physics, the no-communication theorem or no-signaling principle is a no-go theorem from quantum information theory which states that, during measurement of an entangled quantum state, it is not possible for one observer, by making a measurement of a subsystem of the total state, to communicate information to another ...

Superluminal communication is a hypothetical process in which information is conveyed at faster-than-light speeds. The current scientific consensus is that faster-than-light communication is not possible, and to date it has not been achieved in any experiment. Superluminal communication other than possibly through wormholes is likely impossible ...
Wear sunscreen. It may seem obvious, but sun protection is one of the easiest things you can do to dramatically reduce your risk for skin cancer, the experts say. "It is super important to use ...
