#2 Why not two kinds of anti-matter - one that falls down and the other that falls up? As well as two kinds of matter? Since we don't (or at least I don't) understand just what makes gravity work on normal matter, I don't see that it has to have anything to do with the 'anti-ness' of matter at all.

Scientists also scratch their heads over whether antimatter would respond in the same way as matter to gravity, or whether it would move in an different direction at a different speed.


Had a college prof who had his own grand unified theory of matter, and that model predicted matter with "negative mass". It wasn't antimatter, it just had a negative sign in front of the mass; you could have -2kg of it.

I wrote a simple gravity simulation to see how negative masses react to regular masses. The two end up chasing each other through space...

#4 Obviously you've never had a stormy marriage that ended in divorce, Rob, or you would've known that. ;)
