Gas focusing, also known as ionic focusing. Rather than being dispersed, a beam of charged particles travelling in an inert gas environment sometimes becomes narrower. This is ascribed to the generation of gas ions which diffuse outwards, neutralizing the particle beam globally, and producing an intense radial electric field which applies a radially inward force to the particles in the beam.

The Oh-My-God particle was an ultra-high-energy cosmic ray detected on the evening of 15 October 1991 over Dugway Proving Ground, Utah, by the University of Utah's Fly's Eye Cosmic Ray Detector. Its observation was a shock to astrophysicists (hence the name), who estimated its energy to be approximately 3×1020 eV or 3×108 TeV. This is 20,000,000 times more energetic than the highest energy measured in electromagnetic radiation emitted by an extragalactic object and 1020 (100 quintillion) times the photon energy of visible light. Therefore, the particle was an atomic nucleus with a kinetic energy...

The Alcubierre drive or Alcubierre warp drive (or Alcubierre metric, referring to metric tensor) is a speculative idea based on a solution of Einstein's field equations in general relativity as proposed by Mexican theoretical physicist Miguel Alcubierre, by which a spacecraft could achieve apparent faster-than-light travel if a configurable energy-density field lower than that of vacuum (that is, negative mass) could be created. Rather than exceeding the speed of light within a local reference frame, a spacecraft would traverse distances by contracting space in front of it and expanding space behind...

Universal Century technology are technologies from the Universal Century timeline of the Gundam anime metaseries. Although they are only fictional technologies, they form the basics of the Real Robot genre of anime and is influencing real life academic research and different anime series. == History == The Universal Century technologies debuted in Gundam Century, written by editors, academy and studios hired by OUT magazine at that time, later part of the book was endorsed by Sunrise and Bandai, and some of the authors of the articles within Gundam Century became official editors and writers of...

To pinky swear, or to make a pinky promise, is the entwining of the little fingers ("pinkies") of two people to signify that a promise has been made. In the United States, the pinky swear has existed since at least 1860, when Dictionary of Americanisms listed the following accompanying promise: Pinky, pinky bow-bell, Whoever tells a lie Will sink down to the bad place [sic] And never rise up again. Pinky swearing presumably started in Japan, where it is called yubikiri (指切り, "finger cut-off") and often additionally confirmed with the vow "Finger cut-off, ten thousand fist-punchings, whoever lies...
