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.
Memetics is a theory of the evolution of culture based on Darwinian principles with the meme as the unit of culture. The term "meme" was coined by biologist Richard Dawkins in his 1976 book The Selfish Gene, [ 1] to illustrate the principle that he later called "Universal Darwinism". All evolutionary processes depend on information being copied ...
Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the ...
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 ...
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 ...
As long as no one is driving faster than you are. Florida Statute 316.081 requires drivers to move out of the left lane if a faster-moving vehicle is coming up behind them. Failure to do so is a ...
Cosmic ray visual phenomena, or light flashes ( LF ), also known as Astronaut's Eye, are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. While LF may be the result of actual photons of visible light being sensed by the retina, [ 1] the LF discussed ...
A group of self-driving cars in San Francisco were not being very kind to their neighbors earlier this month. So the company behind them says it has since implemented a fix. In a now widely ...
