PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.
[7] [8] The possibility of existence of faster-than-light particles was also proposed by Lev Yakovlevich Shtrum in 1923. [9] The term tachyon was coined by Gerald Feinberg in a 1967 paper titled "Possibility of faster-than-light particles". [3] He had been inspired by the science-fiction story "Beep" by James Blish.

Tachyonic fields play an important role in physics [3] [4] [5] and are discussed in popular books. [1] [6] The term "tachyon" was coined by Gerald Feinberg in a 1967 paper [7] that studied quantum fields with imaginary mass. Feinberg believed such fields permitted faster than light propagation, but it was soon realized that this was not the ...
A NASA probe ventured closer to the sun than any spacecraft in history on Christmas Eve — and it whirled by at astounding speeds that also made it the fastest thing ever made by humans. Just ...

The Star Trek television series and films use the term "warp drive" to describe their method of faster-than-light travel. Neither the Alcubierre theory, nor anything similar, existed when the series was conceived—the term "warp drive" and general concept originated with John W. Campbell's 1931 science fiction novel Islands of Space. [47]
Spinning roughly 641 times per second, it remains the second fastest-spinning millisecond pulsar of the approximately 200 that have been discovered. [7] Pulsar PSR J1748-2446ad, discovered in 2004, is the fastest-spinning pulsar known, as of 2023, spinning 716 times per second. [8] [9]
The universe is expanding faster than previously believed, a surprising discovery that could test part of Albert Einstein's theory of relativity. Astronomers say universe expanding faster than ...
