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?
You are giving the definition for the Big Bang Theory.
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.
Light, and the entire electro-magnetic spectrum, is made up of photons, which are not elements. Electricity is composed of energized electrons - again, not elements. Lastly, gravity, the strong, and the weak forces are not made of elements (if they are made of things at all).
antimatter and dark matter
They can DEFINITELY breathe antimatter
The existence of antimatter was first predicted by physicist Paul Dirac in 1928 as a consequence of his Dirac equation, which unified quantum mechanics and special relativity. The first observation of antimatter particles, specifically positrons, was made by physicist Carl D. Anderson in 1932 while studying cosmic rays.
Antimatter - band - was created in 1998.
Antimatter - album - was created in 1993.
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
Antimatter was discovered in 1928 by Paul Dirac.
