is there such thing called an anti-matter?

Question

ummm.... my friend told me something about anti-matter and i want to know if it does exists...

Answer 1

Yes, apparently...

Antimatter extends the concept of the antiparticle to matter, wherein if a particle and its antiparticle come into contact with each other, the two annihilate —that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc2.

Antimatter is not found naturally on Earth, except very briefly and in vanishingly small quantities (as the result of radioactive decay or cosmic rays). This is because antimatter which comes to exist on Earth outside the confines of a suitably equipped physics laboratory would inevitably come into contact with the ordinary matter that Earth is made of, and be annihilated. Antiparticles and some stable antimatter (such as antihydrogen) can be made in miniscule amounts, but not in enough quantity to do more than test a few of its theoretical properties.

Read Dan Brown's "Angels and Demons", I know it's fiction, but it has a little bit of factual info on the subject mixed in.

Anti-matter is potentially the most dangerous thing that physicists are "playing" with right now.

Answer 2

anti-matter is an extremely interesting subject. there is evidence that it exists, but on this planet it is extremely rare. anti-matter can be described as an atom with an opposite charge. in anti-matter electrons have positive charges (they call these positrons) and protons have a negative charge. these are very rare because anti-matter elements come in contact with matter elements and annhiliate, or cancel out each other. if we could harness the power of antimatter it would be huge. one gram of antimatter could power new york for a day.

Answer 3

Scientists suggest that in their theory of the big bang both equal quantities of matter and antimatter should have been created, the thing is , theoretically when matter and anti matter come into contact they should annialate each other, the unresolved question is why didnt this happen.

Answer 4

Antimatter does exist, but it has been limited thusfar.

Anti-protons, and anti-electrons can be produced, and have been (briefly) combined to form anti-hyrdogen. But no larger atoms or molecules have ever been formed and anti-matter is very short lived as it rapidly anihilates with matter.

Answer 5

Those born and raised in Brooklyn, New York have proved long ago that anti-matter does exist, for example:
I was constantly asked: "Whats-sah-matter-wit-yous??"
I would answer with: "ain't nutten-sah-matter wit mes!"
Just move the "i" in ain't to the back and you get "anti"!!
Glad I could be of help.

Answer 6

anti-matter does exist, although scientist can produce a limited range of particle. its actually very interesting stuff, for example if a electron meets a positron (anrti-electron) they completely cancel each other out and release loads of energy

Answer 7

I beleiev it has been re-created in the lab...very briefly. Theory holds it to be true and the experiment showed it does. Go to the Internet and search for the research.

Answer 8

most scientists think there is, but there are many who dont. it has yet to be proven 100% correct... but remains the best explaination we have for many "problems"

Answer 9

Yes, your mind.
You thing process.
Imagination

Answer 10

yup. me.
