  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. Baryogenesis - Wikipedia

    en.wikipedia.org/wiki/Baryogenesis

    This imbalance has to be exceptionally small, on the order of 1 in every 1 630 000 000 (≈ 2 × 10 9) particles a small fraction of a second after the Big Bang. [4] After most of the matter and antimatter was annihilated, what remained was all the baryonic matter in the current universe, along with a much greater number of bosons.

  4. Astroparticle physics - Wikipedia

    en.wikipedia.org/wiki/Astroparticle_physics

    The finding of an accelerating universe suggests that a large part of the missing dark matter is stored as dark energy in a dynamical vacuum. [ 6 ] Another question for astroparticle physicists is why is there so much more matter than antimatter in the universe today.

  5. 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.

    There appears to be very little antimatter - and on Earth almost none. ... Scientists remain puzzled by antimatter's scarcity in the observable universe. For instance, there is no indication of ...

  7. 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).

  8. Gravitational interaction of antimatter - Wikipedia

    en.wikipedia.org/wiki/Gravitational_interaction...

    The CPT theorem implies that the difference between the properties of a matter particle and those of its antimatter counterpart is completely described by C-inversion. Since this C-inversion does not affect gravitational mass, the CPT theorem predicts that the gravitational mass of antimatter is the same as that of ordinary matter. [5]

    In March, a mother was horrified to find a pedophile symbol on a toy she bought for her daughter. Although the symbol was not intentionally placed on the toy by the company who manufactured the ...
