  2. Baryon asymmetry - Wikipedia

    en.wikipedia.org/wiki/Baryon_asymmetry

    Neither the standard model of particle physics nor the theory of general relativity provides a known explanation for why this should be so, and it is a natural assumption that the universe is neutral with all conserved charges. [3] The Big Bang should have produced equal amounts of matter and antimatter. Since this does not seem to have been ...

  3. The Three Doctors (Doctor Who) - Wikipedia

    en.wikipedia.org/wiki/The_Three_Doctors_(Doctor_Who)

    Omega knocks it over in rage at the paltry offer and the recorder falls out, annihilating everything it meets in the antimatter universe in a flash (having fallen into the force field during the abduction, it was protected from conversion, remaining as normal matter), creating a new universal source of energy, and ejecting the Doctors in the ...

  4. Here’s why the universe has more matter than antimatter - AOL

    All the particles that make up the matter around us, such electrons and protons, have antimatter versions which are nearly identical, but with mirrored properties such as the opposite electric charge.

  5. Baryogenesis - Wikipedia

    en.wikipedia.org/wiki/Baryogenesis

    In physical cosmology, baryogenesis (also known as baryosynthesis [1] [2]) is the physical process that is hypothesized to have taken place during the early universe to produce baryonic asymmetry, the observation that only matter and not antimatter (antibaryons) is detected in universe other than in cosmic ray collisions.

  6. Flatness problem - Wikipedia

    en.wikipedia.org/wiki/Flatness_problem

    The local geometry of the universe is determined by whether the relative density Ω is less than, equal to or greater than 1. From top to bottom: a spherical universe with greater than critical density (Ω>1, k>0); a hyperbolic, underdense universe (Ω<1, k<0); and a flat universe with exactly the critical density (Ω=1, k=0). The spacetime of ...

    In the aftermath, Ultraman and Superwoman are captured with Owlman still on the loose. The other former members of the Syndicate, along with the rest of Earth 3, are killed when that universe is destroyed. Justice League — Justice Underground — The Justice Underground is a heroic superpowered group from the Anti-matter Universe.

  8. Antihydrogen - Wikipedia

    en.wikipedia.org/wiki/Antihydrogen

    In November 2010, the ALPHA collaboration announced that they had trapped 38 antihydrogen atoms for a sixth of a second, [23] the first confinement of neutral antimatter. In June 2011, they trapped 309 antihydrogen atoms, up to 3 simultaneously, for up to 1,000 seconds. [24] They then studied its hyperfine structure, gravity effects, and charge.

  9. Arc of Infinity - Wikipedia

    en.wikipedia.org/wiki/Arc_of_Infinity

    Within a short time, the Doctor's prediction of an unstable transfer begins to come true: Omega's flesh decays and it is clear his new body is not permanent. When the Doctor and Nyssa catch up with him, it is a painful task for the Doctor to use the Ergon's antimatter converter on Omega, expelling him back to his own universe of antimatter.
