The FTL may has three types: page mapping, block mapping and hybrid mapping. Page mapping can has higher performance, but it has bigger FTL metadata size and higher cost, and its usually used on solid state drives. Block mapping can has smaller metadata size and lower cost, but it has lower performance, and its usually used on USB flash drives ...
Charles Stross's books Singularity Sky and Iron Sunrise make use of "causal channels" which use entangled particles for instantaneous two-way communication. The technique has drawbacks in that the entangled particles are expendable and the use of faster-than-light travel destroys the entanglement, so that one end of the channel must be ...
[4] [7]: 72–73 Some science fiction writers attempted quasi-scientific rubber science explanations of this concept. For others, however, it is just a convenient MacGuffin enabling faster-than-light travel necessary for their story without violating the prohibitions against FTL travel in ordinary space imposed by known laws of physics.

For example, if some mechanism allows the full transmission of the leading part of a pulse while strongly attenuating the pulse maximum and everything behind (distortion), the pulse maximum is effectively shifted forward in time, while the information on the pulse does not come faster than c without this effect.

[1] [4] The word was a contraction of "answerable", as the device would allow its users to receive answers to their messages in a reasonable amount of time, even over interstellar distances. [ 5 ] The ansible was the basis for creating a specific kind of interstellar civilization – one where communications between far-flung stars are ...
More than 7.4 million Americans get SSI, which provides monthly payments beyond traditional Social Security benefits to people who may be disabled or have limited resources. About half of those ...
At least two people have died as severe storms and tornadoes tore through parts of Texas and Mississippi on Saturday, officials said, while a parade of atmospheric river-fueled storms batters the ...
