Anti-matter and neutrons
« on: 09/06/2006 19:31:00 »
Anti-matter is made of positive electrons and negative protons.  Would it still be destroyed when it comes in contact with neutrons?  If not, could we explore the possibility of building an atom of both matter and antimatter, by regulating it and not letting the opposite particles touch by using neutrons?

E=MC2... m=deg/360 X C... C= PiD

therefore E=deg/360 X 2(PiD)

Antimatter applies to all the charateristics of the matter not just charge.  Atneutrons anihillate neutrons.

I thought the antimatter repelled mater by definition?

What you do speaks so loudly that I cannot hear what you say.

Would Positrons annaihalate Protons?  Does it have to be the Anti-equivilent of the particle to annaihalate it?

How do you make Atneutrons?

E=MC2... m=deg/360 X C... C= PiD

therefore E=deg/360 X 2(PiD)

There is still uncertainty as to what the gravitational properties of antimatter are, and whether electrically neutral anti-matter will attract or repel normal matter. But electrically charged anti-matter (e.g. positrons and anti-protons) will hold the opposite electrical charge to their normal-matter counterparts, and so they would be mutually attractive.

Not as far as I am aware (in fact, a positron, having the same electrical charge as a proton, would probably have difficulty even getting close to a proton).

My understanding (and maybe someone will correct me on this) is that for mutual annihilation to occur, the particles must be exact opposites, not merely some form of common matter and some form of anti-matter.

Thanks George. You have a good grasp of all this stuff.    

How dose all this sit with The Theory of Inflation?

Inflation has nothing to do with anti-matter, but has to to with the almost (but not quite) even distribution of matter within the universe.

I am not going to quote the entire web page, but you could do worse than to read: http://www.ncsu.edu/felder-public/kenny/papers/inflation.html
