Is there such thing as anti-matter why or why not?

Answer 1

yes. antimatter is exactly like matter exept for one detail. Every particle in matter is has an anti equivilant to it. for example, a proton, which is a positively charged particle in the nucleus of an atom, has an anti-proton, which is a negatively charges particle in the nucleus of an anti-atom. A positron is the anti-electron which orbits an anti-atom. there are 32 known subatomic particles in total including anti-particles. Because matter and anti-matter are oppositely charged, the rarely come into contact, which is a good thing. When matter and anti-matter do come into contact, they are both anihilated spontaniouslyl, and become pure energy, so if a teaspoon of sugar met a teaspoon of anti-sugar, the resulting explosion would absolutely dwarf both Little Boy and Fat Man put together, (Little Boy is the name of the nuke that hit Hiroshima, and Fat Man is the name of the Nagasaki nuke) and could wipe out an area the size of Hawaii (yes, all of the Hawaiian Islands) or larger. It is theorized that when the Big Bang occured, that there was an equal amount of matter as anti-matter, and they were constanlty battling and destroyed eachother. It is also theorized that what is left of the universe is just the smoke of the Big Bang.
