Yes I remember now.
If I remember the Hadron Collider created a minute amount of anti-matter a while ago.It was also further explained that if it came into contact with 'regular' matter they would both annihilate each other :o

Dark matter and antimatter are not the same thing. Antimatter has already been experimentally produced for years now, it's just much too hard and costly to produce it in anything more than tiny quantities.

And yeah, antimatter and matter coming into contact annihilate each other, converting all of their mass into energy.

What exactly IS anti-matter if its not composed of matter,or things we can see,touch and smell?

Secondly,if there IS a god then I reckon it is possibly anti-matter yet with a consciousness that is always expanding.

:hmmm:

Interesting.

See #18

Its theorized that if the universe formed differently that us, our planet and galaxy would have been formed of anti-matter instead of matter. We would not know the difference however, to us anti-hydrogen and anti-oxygen would make water and hydrogen and oxygen would be highly rare and highly dangerous.

Moral is, if you ever encounter an alien, before grasping its manipulating appendage in friendship toss a rock or coin at it: if it doesn't explode in to a burst of pure energy its probably safe to touch.

Antimatter is basically matter comprised of antiparticles. Antiparticles are just like regular particles, but with an opposite charge. You can see antimatter if you could ever view it in sufficient quantities, since it reflects light just the same. You can touch it as well, but given how it annihilates on contact with matter, that's probably not the best idea.

So basically matter and antimatter would APPEAR identical to us,save for the difference in electrical charge?

Exactly. Thats why I said, if you meet an alien, toss a bit of matter at it first, as it could be an Antimatter alien and you would never know it. :03:

How about chuck it a banana or something? :haha:
Thanks for the warning though,I dont want my first meeting with a Grey TOO explosive!

I would imagine throwing something at it would likely get you killed in the resulting explosion. Much better to just hide behind your lead blast shield and watch if it doesn't die from random floating particles... :O:

Or I could send in Jim to sort the problem out :DL

I doubt it would 'matter' either way :doh:

As a matter of fact you might be right.
