  2. 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.

  3. 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 a 2019 interview marking his 70th birthday, Joel commented on why he rarely plays the song anymore: "He didn’t age well. Captain Jack’s been demoted to Private Jack. In the verses, there’s only two chords, and it goes on and on, and it’s kind of a dreary song if you think of the lyrics. The kid is sitting home jerkin’ off.

  5. 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 ...

  6. 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.

  9. Negative Zone - Wikipedia

    en.wikipedia.org/wiki/Negative_Zone

    The Negative Zone in the Marvel Universe is used as a fictional universe parallel to Earth's. While the universes are similar in many respects they are different in that: all matter in the Negative Zone is negatively charged; the Negative Zone is entirely filled with a pressurized, breathable atmosphere; and near the center of the Negative Zone is a deadly vortex of unspeakable power.
