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, i.e. the imbalance of matter and antimatter (antibaryons) in the observed universe.
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 ...
Antimatter – Material composed of antiparticles of the corresponding particles of ordinary matter; Dark energy – Energy driving the accelerated expansion of the universe; Dark matter – Concept in cosmology; Gravitational interaction of antimatter – Theory of gravity on antimatter; Mirror matter – Hypothetical counterpart to ordinary ...
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.
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.
As with the majority of his own Antimatter recordings, Moss elected to perform the core instruments of guitars, bass, synths and e-bows himself. [6] Guest musicians were drafted in the form of Fab Regmann (drums), Carla Lewis (vocals), Julie Rodaway (flute), Paul Thomas (saxophone) and Vardan Baghdasaryan ( kamancheh ).

Why does the observable universe have more matter than antimatter? (more unsolved problems in physics) In physical cosmology , leptogenesis is the generic term for hypothetical physical processes that produced an asymmetry between leptons and antileptons in the very early universe , resulting in the present-day dominance of leptons over ...
