antimatter and dark matter
No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions. Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.
Previous answer "The existence of antimatter is just a lower less advanced form of dark matter" this is completely wrong, Antimatter is quite the opposite of 'normal' matter. It is made up of positrons that orbit around the nucleus in shells and have a positive charge. Anti-proton (a proton with a negative charge) and neutrons stay the same as they have no charge and are in fact neutral. dark matter is simply matter that doesn't give out light
no, everything that we can interact with is matter. antimatter completely demolishes itself if it comes into contact with its matter counterpart. the matter and antimatter together makes up the M (mass) of the E=MC squared equation. dark matter, which just passes right through matter and antimatter, which we call WIMPs, (Weakly Interacting Mass Particles or something. i forgot exactly)
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
No. Antimatter and dark matter are two entirely different things. Dark matter is a form of matter (for lack of a better word) that only interacts with ordinary matter via gravity. Antimatter is matter consisting of antiparticles. For every normal particle type there is an antiparticle of the same mass but opposite charge. If a particle meets its antiparticle the two annihilate each other and turn into energy.
That is one of the unsolved problems in cosmology. There seems to be a slight difference between matter and antimatter, that is, the symmetry between matter and antimatter is not perfect. But the details of baryogenesis are not known yet.
By recreating Big Bang conditions, scientists at CERN trie to answer following questions:Why is there no-more antimatter left, although both, matter and antimatter were resulting from the Big Bang in equal parts and thus, should've annihilate themselves?Why do particles have mass? What is mass? Is the origin of mass the Higgs-boson?Does dark matter exist? What is dark matter?Do extra dimensions exist?
Matter, or antimatter.
When antimatter comes into contact with matter, they annihilate each other.
Initially the 9g of remaining matter would survive. Each particle of antimatter can only annihilate with one other particle of antimatter. At this point the 1g of antimatter would cause an explosion equivalent to that of 200000 pounds of TNT. Causing both groups of matter and antimatter to be obliterated.
