Thanks to ghost for clearing up the "M" theory,
theoretically, it's one that makes sense, there was several theories, that all disagreed with the other, but none of them actually made sense until the "M" theory came into play, which actually fitted them all, and was mathematically possible.
As for the marble, what happens though if you keep picking it up at EXACTLY the same point, it never goes past that position, so therefore, is it possible it could go there?
Theoretically yes, but because of your intervention it never does.
No-one cares where I'm from or how old I am
