What is Anti-matter?

Question

anti protons anti neutrons and anti electrons
quarks tachyons..? can someone explain
Is Dr Stephen Hawking out there ?

Answer 1

According to prevailing theory, all matter has an anti-matter equivalent. Many of these anti matter equivalents have in fact been identified in super colliders where matter and anti-matter have been created from energy.

And to a point, the colliders have been unable to create matter without also making its anti matter at the same time. In other words, anti matter is a sort of by product of making matter from energy.

The so-called positron is the anti matter for the ordinary electron for example. The positron is identical in every way but one to the electron. Its one difference is that the positron has a plus charge and the electron has a negative charge. In fact, difference in charge is a major differential for the other particles and anti-particles as well.

Matter and anti-matter do not get along very well. In fact, when they collide, the anti-matter particle loses the battle and becomes energy mostly in the form of photons (like light). Theory has it that, shortly after the big bang, the nascent universe was equally filled with matter and anti matter. But soon the unstable anti matter disintegrated into energy. So now we find only matter in its natural form.

All those quanta you listed (protons, neutrons, etc.) are just bundles of energy and/or mass. They are the constituents of all atoms and quanta that make up our universe...and that chair you are sitting on as you read this.

Some of the particles are made up of other particles. Protons and neutrons, for example, are made up of quarks. Some, like bosons and gluons, appear to have no other constituents. There are dozens of these distinct particles, but they are all the building bricks that you, I, and the rest of the universe are made of.

You should also know about string/M theory. This WAG posits that all those particles and anti particles you and I mentioned are actually made up of infinitely thin, very short one dimensional vibrating strings. And how each string appears to us, in our universe, depends on the frequency it is vibrating at. [See source.]

Answer 2

It's the opposite of matter. It's the empty space between electrons and things. If you think about it, because of that empty space between the nucleus of an atom and its electrons, you're 90% nothing.

You can learn more on Wikipedia though you should look into its sources to make sure you're getting the right information.

Answer 3

Anti particles just have opposite charges. Anti electrons are called positrons because they are positively charged, instead of negatively like like electrons. If anti mater and regular mater come into contact, they cancel each other out by attracting and converting into pure energy, resulting in a nuclear explosion. EDIT/////////////////////////////////////////////////////////////// The person below me is Wrong when he says antimatter "losses the battle". They BOTH lose the battle because they cancel each other out completely and are both converted into photons and other particles.

Answer 4

Google it. From what I understand, anti-matter is the opposite of matter. It's still a form of matter, just.... different. :)

Answer 5

it does NOT matter
