Erik Holmes unfortunately expressed: > Antimatter is pretty much just like normal matter except that the molecules all spin in reverse. Erik, it is a really, really, _really_, REALLY good idea to make sure of your facts before expressing them in a public forum. Otherwise you end up embarrassed and looking like, well, like you didn't do your homework. (Hint: Antimatter isn't spin, there's this small matter of charge and it isn't at all about molecules, except in the sense that antimatter could potentially form such things from the antiparticles. I know this much from just a very high-level lay understanding. There are physicists in this group.) -- Frank Mayhar frank at exit.com http://www.exit.com/ Exit Consulting http://www.gpsclock.com/ http://www.exit.com/blog/frank/
