is there a such thing as ANTI-MATTER?

Question

do you believe in this>?

Answer 1

There is. It's been created in high-energy collisions inside of particle accelerators; and was a little less than half the material made during the Big Bang.

Answer 2

No need "to believe" in it. We make it all the time in high energy physics facilities and CERN has a new set of equipment to actually collect some of it for experiments on anti-particles and even anti-atoms at rest:

A piece of general advice: when asking a science question, it is best to avoid the word "believe". At best it shows is that you don't know what science is and that you have a very poorly developed sense for the difference between faith and knowledge.

The first part of your question was perfectly fine. It says that you lack a piece of information and you want a specialist to give you a definitive answer. This shows that you are smart and want to learn. Nobody will look down on you for asking. Actually, quite to the contrary. The more people ask, the better.

The second part about beliefs, on the other hand, looks rather ignorant. It would probably be fine if you were twelve years old or younger. If you are older than that, I personally would expect you to know better. Your parents and teachers should expect you to know better and they should have explained the difference to you. If you are an adult, your question would be nothing but another proof for how bad your education was.
Which, again, is not your fault... but it will certainly be your problem.

Answer 3

Definitely yes.

Anti-particles of electrons and protons really exist.

The anti-particle to the electron is the positron, and it is produced by either radioactive decay (natrually occuring process), or by collision of a high energy gamma ray with an atom (a pair of an electron and positron is produced).

Anti-protons have been produced in high energy particle colliders, and have been observed in small quantities in the stratosphere near the poles (coming from space).

Even whole anti-hydrogen atoms (an anti-proton and a positron) have been produced and kept for short periods of time, albiet very very small quantities (like 100 atoms or so).

Anti matter has an opposite electric charge to its matter counterpart. It does not have negative mass, just opposite charge.

Answer 4

There is an anti-particle for every fundamental particle. There are up and down quarks, and anti-up and anti-down quarks. Two up and one down quarks make a proton, where two anti-up and one anti-down make an antiproton. There are electrons and anti-electrons sometimes called positrons. Even neutrinos have antineutrino counterparts though because neutrinos lack charge there is little to distinguish them from each other.

Answer 5

yes when it touches regular matter it forms PURE energy?
