Anti matter isn't created, but "formed". No one can create matter (or anti-matter) nor destroy it.
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.
Yes it is. This does not mean that it has the properties ascribed to it in any particular work of fiction (Star Trek's version is reasonably realistic, Green Lantern's version is hopelessly silly), but yes, something by that name does really exist. ************************************************************************* Antimatter is real. Some scientists believe that antimatter is a perfect symmetry to matter. Antimatter is very dangerous and powerful. When matter and antimatter collide, an annihilation happens. Things around it will disappear.
The person who discovered antimatter was Paul Dirac. Paul Dirac.
We have created 20 nanograms of antimatter. To get you on track, one nanogram is a billionth of a gram. Antimatter is very hard to make, so far only a very small quantity has ever been produced; much less than a milligram has ever been produced and yes there is a way to store it. It's called the penning trap. The penning trap is a container in extreme vacuum and magnetic fields. This is to prevent the antimatter from touching air, since air is made of matter.
Its is formed when two atoms bang into eachother. Scientists are trying to trap antimatter to study it and learn more about it.
Antimatter - band - was created in 1998.
Antimatter - album - was created in 1993.
Lights Out - Antimatter album - was created in 2003.
antimatter has always been here but nobody knew about it until recently
You are giving the definition for the Big Bang Theory.
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.

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.
"Antimatter" is not negative mass. Mass is a positive quantity for both matter and antimatter. So gravity is always attractive, even if one of the masses in the relationship happens to be antimatter. If such a thing as negative mass exists, then the forces between it and a lump of normal mass would be repulsive ones. Antimatter is observed routinely, but no evidence of negative mass has ever been observed. When matter & antimatter annihilate energy is released per E = mc2 where m corresponds to the sum of their masses. If the antimatter had negative mass then instead of a positron/electron annihilation releasing energy corresponding to twice the electron mass (as it does) the mass of the electron and negative mass of the positron would cancel resulting in no energy release (this does not happen). This proves that both matter & antimatter have positive mass, without even referring to gravity. As they both have positive mass their gravity will be attractive not repulsive.
