    cant remember where i read it, but am i right at thinking that though highly highly unlikely one solid object could pass through another?

    eg if all the atoms were lined up to give perfect conditions?

    not sure if i read it in hawkings, bodanis or bryson

    Never heard of that one, as far as I know it can be considered like two magnetic fields, they can only 'push' each other out of the way so to speak. I think atomic bonds are the same - if not wouldn't everything just fall apart?

    Pulses of low frequency electromagnetic radiation can pass quite efficiently through a solid object. However one solid object cannot pass through another solid object without deformation of at least one of those solid objects.

    yeah that makes sense but i remember reading about in perfect alignment of all atoms could theoretically make it possible for the atoms to be far enough apart to pass through but the possiblility of atoms being in that position is near impossible

    was it in a hawking book?

    Well quantum mechanics seems to imply that nearly anything is possible and that the classical laws of physics which govern our macroscopic world are not absolute but only highly probable. However when does a small chance of something else happening become so insignificant that it is not worth mentioning. Is the probability of 10^-1000 that the apple falls up instead of down worth mentioning? Would any one try dropping the apple any significant portion of the 10^1000 times to see if the unlikely ever happens?

    Probably, It was he he he he ha ha ha hafter all who proposed Haw Haw Haw Hawking radiation, after that I guess anything's possible in his world!. :wink:
