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 ...
Proxima Centauri, the nearest star outside the Solar System, is about four and a half light-years away. [4] In this frame of reference, in which Proxima Centauri is perceived to be moving in a circular trajectory with a radius of four light years, it could be described as having a speed many times greater than c as the rim speed of an object ...
[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.
[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 ...
If you’re stuck on today’s Wordle answer, we’re here to help—but beware of spoilers for Wordle 1271 ahead. Let's start with a few hints.
The book begins with an account of a bicycle accident in Stockholm in which Tegmark was killed—in some theoretical parallel universes, though not in our own. [2] The rest of the book is divided into three parts. [3] Part one, "Zooming Out," deals with locating ourselves in the cosmos and/or multiverse. Part two, "Zooming In," looks for added ...

The experiment created a form of neutrinos, muon neutrinos, at CERN's older SPS accelerator, on the Franco–Swiss border, and detected them at the LNGS lab in Gran Sasso, Italy. OPERA researchers used common-view GPS , derived from standard GPS, to measure the times and place coordinates at which the neutrinos were created and detected.
