Fig. 1 What OPERA saw. Leftmost is the proton beam from the CERN SPS accelerator. It passes the beam current transformer (BCT), hits the target, creating first, pions and then, somewhere in the decay tunnel, neutrinos. The red lines are the CERN Neutrinos to Gran Sasso (CNGS) beam to the LNGS lab where the OPERA detector is. The proton beam is ...
[1] [2] Some of these proposals find loopholes around general relativity, such as by expanding or contracting space to make the object appear to be travelling greater than c. Such proposals are still widely believed to be impossible as they still violate current understandings of causality, and they all require fanciful mechanisms to work (such ...
FTL: Faster Than Light is a roguelike game created by indie developer Subset Games, which was released for Windows, MacOS, and Linux in September 2012. [4] In the game, the player controls the crew of a single spacecraft, holding critical information to be delivered to an allied fleet, while being pursued by a large rebel fleet.
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.
One common assumption is that the multiverse is a "patchwork quilt of separate universes all bound by the same laws of physics." [2] The concept of multiple universes, or a multiverse, has been discussed throughout history, including Greek philosophy. It has evolved and has been debated in various fields, including cosmology, physics, and ...
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 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 ...
Ursula K. Le Guin first used the word ansible in her 1966 novel Rocannon's World. [1] [4] Etymologically, the word was a contraction of answerable, as the device allowed its users to receive answers to their messages in a reasonable amount of time, even over interstellar distances.
