Red matter is not antimatter. The new movie doesn't really explain red matter except from visual clues. It is kept as a fluid, repels itself from matter, highly unstable, and reacts to form a small product dense enough to trap light (i.e. black hole).
So I'm not really sure what red matter is supposed to be in a 'real' science context, but I've seen enough Star Trek to know that it is not antimatter, which would have reacted immediately upon touching that needle extractor thing-a-ma-jig. Hope this helps.
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?
Yes. If we could communicate with intelligent life in a distant galaxy composed completely of anti-matter, we would have no way of determining that fact. No matter what experiment we asked them to perform, their results would be identical to the results we see in our galaxy composed of matter.
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.
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
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 observes and obeys the same fundamental forces that matter does:gravityelectromagnetismweak interactivestrong interactiveA positron, which is the anti-particle of the electron, for example, has the same mass as an electron and experiences the same attraction to all other matter (gravity) as an electron. That same positron is repelled by positively charged particles and attracted to negatively charged particles (electromagnetism).
Just the same as if normal matter falls in. The matter or antimatter will stay there, increasing the mass of the black hole (and making it more "hungry", i.e., making its gravity stronger).
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.
Sir Issac Newton proposed theory of gravity. He formulated the relation between the force of gravity and the mass and the distance between the masses. This theory failed to explain as to why there is attraction between the masses and not repulsion. With every attraction you have to have corresponding repulsion. That problem is resolved with the discovery of antimatter. So like attracts like. So matter attracts matter and antimatter attracts antimatter. This fallows that matter repel antimatter. So force of gravity between the two masses of matter or two masses of antimatter is directly proportional to the product of masses or anti-masses (Antimatter). The force of repulsion will be directly proportional to the product of mass and anti-mass (Antimatter). It fallows that the force of repulsion is inversely proportional to square of distance between the two.
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.
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.
