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.
antimatter has always been here but nobody knew about it until recently
When antimatter comes into contact with matter, they annihilate each other.
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?
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)
A molecule. But all the compounds ans elements in the universe are made from atoms. (and possible from antiatoms in the undiscovered now antimatter).
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.
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".
All things in the known universe (excluding antimatter) are in fact made of 118 elements. However in history it was believed that earth, wind, water and fire were the building blocks of everything.
antimatter and dark matter
Yes, antimatter - as was recently produced at CERN.
They can DEFINITELY breathe antimatter
Antimatter - band - was created in 1998.
Antimatter - album - was created in 1993.
The matter of the astronaut causes the antimatter to anhilate each other, creating energy close to the energy produced by the equation E=mc2.
Antimatter was discovered in 1928 by Paul Dirac.
