Dark/Anti Matter

Hi, i was wondering if any Ats members could tell me what dark and anti matter is, possibly post links?

Thanks

Well first of all, they are two totally different things. Dark Matter is the matter which some folks postulate exists in the universe that we cannot (for whatever reason, and there are a boat load of possible reasons given) see.

Anti-matter is:

Rather than trying to explain it, I hope those links will suffice, if not feel free to ask specific questions and I'll answer as best as I can.

The basic properties of dark matter (as I understand) are that they have gravity. If you apply string theory to the situation you get interesting results.

If gravitons (the partical that creates gravity) can cross through the branes (dividers between universes) and still have a gravitational effect then it is possible that the "dark matter" we theorize about could just be gravitons travelling through multiple universes.

Thanks for the information, perhaps you can tell me about the string theory

we actualy have anti matter i posted a link on this awhile back someone in sweedan inveted a machine that makes it or someting

For information on string theory you can read a book called The Elegant Universe. Or, you could go to www.pbs.org...

Jim,

No offense, but if you aren't a physics geek (in which case you would know about string theory), do yourself a favor and forget about it.. it will make your head hurt... A LOT..

To Jim,

Do not listen to that advice. Physics geek or not, some of the most amazing information you could ever aquire comes from advanced physics. The reward for pursuing this info is far greater than the trouble you will go through to get it. Don't forget about it. Embrace any headaches! You will be much happier if you do.

For all I know, you could be 12 years old. Maybe you have never even heard of string theory before today. Just because you ask about it, means you show some sort of intrest on some sort of level. Hopefully you take the time to expand on it.

It was a JOKE!!!.. note the

sheesh.. sometimes I wish there was an 'intonation' tag to go with the smilies

Probably the best thing to do to get a basic understanding of string throry is to go to this website (NOVA on PBS) and watch the videos on it. Very informative, and put in a manner that can be understood without understanding of complex math. Elegant Universe on NOVA

well crap, I see now that someone already beat me to posting the Elegant Universe site link... sorry about that....
