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 ...
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 noted by Gregory Benford et al., special relativity implies that tachyons, if they existed, could be used to communicate backwards in time [2] (see tachyonic antitelephone). Because time travel is considered to be non-physical, tachyons are believed by physicists either not to exist, or else to be incapable of interacting with normal matter.
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.
Due to touring fatigue, Mick Moss put the Antimatter live band on semi-hiatus beginning in March 2017, and set to work on the 7th Antimatter album, which was tentatively titled 'Refraction'. Speaking in the 2018 documentary 'Finding Enlightenment', Moss says that he "had known for a long time exactly what the 7th Antimatter album would be about ...
Anti universe may refer to: Antimatter, matter composed of the antiparticles; Multiverse, the hypothetical set of all universes; Anti-gravity, a hypothetical ...
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.
Antihydrogen atoms should be attracted to other matter or antimatter gravitationally with a force of the same magnitude that ordinary hydrogen atoms experience. [2] This would not be true if antimatter has negative gravitational mass , which is considered highly unlikely, though not yet empirically disproven (see gravitational interaction of ...
