Faster-than-light ( superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light ( c ). The special theory of relativity implies that only particles with zero rest mass (i.e., photons) may travel at the speed of light, and that nothing may travel faster.
Occupation. Railroad worker. Known for. American folk hero. John Henry is an American folk hero. An African American freedman, he is said to have worked as a "steel-driving man"—a man tasked with hammering a steel drill into a rock to make holes for explosives to blast the rock in constructing a railroad tunnel.
Superluminal motion. In astronomy, superluminal motion is the apparently faster-than-light motion seen in some radio galaxies, BL Lac objects, quasars, blazars and recently also in some galactic sources called microquasars. Bursts of energy moving out along the relativistic jets emitted from these objects can have a proper motion that appears ...
In people with Cushing syndrome, “too much cortisol leads to a more rounded face, pinkish red cheeks, thinner skin with easy bruises, a puffy neck, and a worsening upper back hump,” Dr. Ghalib ...
Imagine being woken up at 4 a.m. by cars honking at each other. That's what some San Francisco residents have been dealing with for weeks, as the Waymos can be heard in this video honking and ...
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 ...

Law of holes. An excavator that is in a hole and, per the Law of Holes, has stopped digging. The law of holes, or the first law of holes, is an adage which states: "if you find yourself in a hole, stop digging." It is used as a metaphor, warning that when in an untenable position, it is best to stop making the situation worse. [ 1][ 2]
