  2. Antimatter - Wikipedia

    en.wikipedia.org/wiki/Antimatter

    Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe. Antimatter galaxies, if they exist, are expected to have the same chemistry and absorption and emission spectra as normal-matter galaxies, and their astronomical objects would be observationally identical, making ...

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

    www.aol.com/why-universe-more-matter-antimatter...

    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.

    “A kilogram of matter-antimatter annihilation releases a whopping energy that’s over 250 times greater than that of nuclear fusion and over 8 orders of magnitude (108) more than chemical ...

  5. Plasma cosmology - Wikipedia

    en.wikipedia.org/wiki/Plasma_cosmology

    The original form of the theory, Alfvén–Klein cosmology, was developed by Hannes Alfvén and Oskar Klein in the 1960s and 1970s, [3] and holds that matter and antimatter exist in equal quantities at very large scales, that the universe is eternal rather than bounded in time by the Big Bang, and that the expansion of the observable universe ...

  6. Baryon asymmetry - Wikipedia

    en.wikipedia.org/wiki/Baryon_asymmetry

    In physical cosmology, the baryon asymmetry problem, also known as the matter asymmetry problem or the matter–antimatter asymmetry problem, [1] [2] is the observed imbalance in baryonic matter (the type of matter experienced in everyday life) and antibaryonic matter in the observable universe.

  8. CPT symmetry - Wikipedia

    en.wikipedia.org/wiki/CPT_symmetry

    The implication of CPT symmetry is that a "mirror-image" of our universe — with all objects having their positions reflected through an arbitrary point (corresponding to a parity inversion), all momenta reversed (corresponding to a time inversion) and with all matter replaced by antimatter (corresponding to a charge inversion) — would ...

  9. Antimatter weapon - Wikipedia

    en.wikipedia.org/wiki/Antimatter_weapon

    An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
