antimatter has always been here but nobody knew about it until recently
You are giving the definition for the Big Bang Theory.
When antimatter comes into contact with matter, they annihilate each other.
Yes. Antimatter is only a point of view concept : we can imagine any object made of what we call antimatter. According to his point of view, we would be made of antimatter. Moreover, a number of large areas of the universe, that doesn't have any contact with each other, may be made of antimatter. we wouldn't have any mean to know from where we are.
An atom of antimatter does not contain any electrons. The equivalent of an electron in antimatter is a positron, which has charge +1.
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 - band - was created in 1998.
Antimatter - album - was created in 1993.
Lights Out - Antimatter album - was created in 2003.

The founder of antimatter is considered to be the physicist called Paul Dirac in 1928-1930. He created a mathematical equation which predicted the existence of antiworld made out of antimatter.
A thing that not matter is antimatter. It has been created by man.
Scientists "speculate" that the Big Bang created antimatter, but it was destroyed when coming into contact with stars, planets, and other matter.
Antimatter was discovered by Paul Dirac in 1928.
It isn't a matter of temperature. It is created in high-speed collisions like those observed in the hadron particle collider. Antimatter is naturally occurring. It has only been created in minute amounts and costs a fortune. One kilogram of antimatter would create an explosion with the power of a 20 megaton nuclear bomb.
Current physical theory tends to indicate there should be a symmetry expressed in the form of a parity between matter and antimatter created in the Big Bang, with no preference for matter over antimatter; this explosion should have created equal amounts of both, which would then annihilate each other. However, the universe tends to be dominated so far as we can tell by matter and no significant regions of antimatter have yet been detected. This would indicate an asymmetry or bias in favor of matter's creation, which is somewhat mysterious and remains a subject of research. In any case, this bias of matter over antimatter is believed to be extremely small - such that it may have been for every billion particles of antimatter created, there were a billion and one particles of matter.
It may have to do with the way the universe was created. Certainly if there was a lot of antimatter created, much of it may well have come in contact with matter through the billions of years the universe has existed. That would have resulted in the conversion of that antimatter (along with a like amount of matter) into energy. There may not have been much antimatter around to begin with, too. But, since the amount of visible matter represents less matter than has been calculated to exist in the uinverse, it may be that there is a good bit of antimatter out there somewhere. Not likely, but possible.
They can DEFINITELY breathe antimatter
