In Ender's Game, Colonel Graff states that "somebody dredged the name ansible out of an old book somewhere". [9] In an answer on the question-and-answer website Quora, Card explained why he chose to reuse the word "ansible" for an FTL communication device instead of developing a new in-universe name for one: In a FTL universe, you have several ...
Faster-than-light (superluminal or supercausal) travel and communication are the conjectural propagation of matter or information faster than the speed of light in vacuum (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.
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 ...
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 [ 1 ] because, in a Lorentz-invariant theory, it could be used to transmit information into the past .
In science fiction, hyperspace (also known as nulspace, subspace, overspace, jumpspace and similar terms) is a concept relating to higher dimensions as well as parallel universes and a faster-than-light (FTL) method of interstellar travel. In its original meaning, the term hyperspace was simply a synonym for higher-dimensional space.
The glitch's effect was to decrease the reported flight time of the neutrinos by 73 ns, making them seem faster than light. [16] [17] A clock on an electronic board ticked faster than its expected 10 MHz frequency, lengthening the reported flight-time of neutrinos, thereby somewhat reducing the seeming faster-than-light effect.
The Alcubierre metric defines the warp-drive spacetime.It is a Lorentzian manifold that, if interpreted in the context of general relativity, allows a warp bubble to appear in previously flat spacetime and move away at effectively faster-than-light speed.
The Open-Source Lab: How to Build Your Own Hardware and Reduce Research Costs by Joshua M. Pearce was published in 2014 by Elsevier. The academic book is a guide, which details the development of free and open-source hardware primarily for scientists and university faculty. [1]
