They would annihilate each other equally. Every electron that encounters a positron (the antimatter equivelant to an electron), every proton that encounters an antiproton and every neutron that encounters an anti-neutron would completely annihilate; both the matter and antimatter particle would fully transform into energy with no residual matter (nor antimatter) if the touch were somehow perfect.
The amount of energy produced is enormous for even a small amount of matter/antimatter annihilation. The amount of energy released is dependent on how much matter and antimatter annihilate each other based on Einstein's famouse equation, e = mc2, which means energy (e) is equal to mass (m) times the square of the speed of light (c). Since light is incredibly fast, squaring it is a huge multiplier to mass. Nuclear fission (atomic bombs) and nuclear fusion (hydrogen bombs) generate their energy based on this same formula, but only a relatively small amount of the matter used in fission or fusion is converted into energy. By comparison, all of the matter and antimatter that come into contact will convert into energy, so the power of an explosion resulting from a matter/antimatter annihilation would be many times more energetic than even a hydrogen bomb of similar mass.
The largest bomb ever detonated in the history of manking was the Tsar Bomba, a fusion or h-bomb which yielded an explosive force of 50 million tonnes of TNT. The bomb itself weighed 27,000 kilograms.
By comparison, if you had a combined total of 27,000 kilograms of matter and antimatter, and created an annihilation bomb (putting all of the matter and antimatter into contact with each other), the resulting explosion would be
1,159,920 megatonnes (or 1.15992 teratonnes) or more than twenty-three thousand times as powerful as the Tsar Bomba! This is huge, but wouldn't quite destroy the earth though it could certainly exterminate a lot of life. The "dinosaur killer" asteroid, estimated to have been maybe 15 kilometers across and striking the earth at 20 km/s, was more than four thousand times as powerful as this.
When antimatter comes into contact with matter, they annihilate each other.
You are giving the definition for the Big Bang Theory.
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.
1. Why is there more matter than antimatter in the Universe? Or: Why is there matter at all? (If there were the same amount of matter and antimatter, and it came into contact, it would quickly get destroyed. 2. If antimatter is so abundant, how come we've never come in contact with it or have been able to observe it?
Antimatter is a type of matter that has the opposite properties of normal matter. When a particle of matter meets its corresponding antiparticle, they annihilate each other, releasing a large amount of energy in the process. Antimatter is rare in the universe and is mostly created in high-energy environments like particle accelerators.
If you were to touch antimatter, it would result in a violent and explosive reaction, releasing a large amount of energy. This is because when antimatter comes into contact with regular matter, they annihilate each other, converting their mass into energy.
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".
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.
Antimatter is a type of matter that is the opposite of regular matter, with particles that have opposite charges. When antimatter comes into contact with regular matter, they annihilate each other, releasing energy in the form of gamma rays. Antimatter does not have a specific appearance, as it is not visible to the naked eye.
During a matter-antimatter reaction, particles of matter and antimatter collide and annihilate each other, releasing a large amount of energy in the form of gamma rays and other particles.
When antimatter comes into contact with matter, they annihilate each other.
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
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.
No, Antimatter while annihilate our matter, meaning that it will completely convert our matter to light and heat, however antimatter is highly theoretical, and the LHC probably will not create any.

The concept of antimatter affects our understanding of time by challenging the symmetry between matter and antimatter. Antimatter particles have properties that are opposite to those of their corresponding matter particles, leading to questions about why there is more matter than antimatter in the universe. This imbalance could potentially impact our understanding of the fundamental laws of physics, including those related to time.
