  2. Antimatter - Wikipedia

    en.wikipedia.org/wiki/Antimatter

    Antimatter cannot be stored in a container made of ordinary matter because antimatter reacts with any matter it touches, annihilating itself and an equal amount of the container. Antimatter in the form of charged particles can be contained by a combination of electric and magnetic fields, in a device called a Penning trap .

  3. Dark matter - Wikipedia

    en.wikipedia.org/wiki/Dark_matter

    It is dark matter composed of constituents with an FSL much smaller than a protogalaxy. This is the focus for dark matter research, as hot dark matter does not seem capable of supporting galaxy or galaxy cluster formation, and most particle candidates slowed early. The constituents of cold dark matter are unknown.

  4. 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.

    "On Earth, most antimatter that occurs naturally is produced from cosmic rays - energetic particles from space - that collide with atoms in the air and create antimatter-matter pairs," said ...

  6. Alpha Magnetic Spectrometer - Wikipedia

    en.wikipedia.org/wiki/Alpha_Magnetic_Spectrometer

    The visible matter in the Universe, such as stars, adds up to less than 5 percent of the total mass that is known to exist from many other observations. The other 95 percent is dark, either dark matter, which is estimated at 20 percent of the Universe by weight, or dark energy, which makes up the balance. The exact nature of both still is unknown.

  7. 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, i.e. the imbalance of matter and antimatter (antibaryons) in the observed universe.

    In the ongoing science quest to observe dark matter, there’s a new method in town. Researchers from Cornell University said in a new preprint paper (not yet peer reviewed or published) that dark ...

    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 ...
