its hypothetical, it shouldn't exist...
Antimatter is one of the most powerful energy sources known, but there are theoretical concepts such as dark energy or exotic matter that could potentially harness even more energy. However, as of now, antimatter remains one of the most powerful energy sources that we know of.
An explosion generated by antimatter is four times more powerful then a nuclear bomb
If such a device could be made, it would be a lot more powerful than a nuke of similar size, as ALL the mass of the antimatter and neutralising matter would be anhialated and turned to energy, instead of a small fraction of total mass of uranium, plutonium etc. Currently not a real threat to the world as antimatter is extremely expensive to produce and the total amount manufactured to date would only power a 60 watt light bulb for a few hours, and cost $ billions to produce. Ds1ao: with on gram of antimatter you can make a 43 kiloton bomb (more than three times as powerful as the bomb dropped on Hiroshima
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".
They can DEFINITELY breathe antimatter
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.
Antimatter - band - was created in 1998.
Antimatter - album - was created in 1993.
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, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
With a fission bomb (A-bomb) there is a limit of how large it can be. With a fusion bomb (H-bomb), there is NO limit to how large one can be. There may be a limit as to the size of a DELIVERABLE fusion bomb. But an H-bomb that isn't intended to be moved anywhere doesn't have a yield (size/power) limit. So yes, an H bomb is the most powerful weapon that mankind has create, to date. An antimatter bomb could be more powerful, but mankind has yet been able to collect, handle, store antimatter in sufficient amounts as to create a powerful weapon.
Antimatter was discovered in 1928 by Paul Dirac.
