I understand that matter cannot pass through other solid matter because of the electrons that orbit an atom prevents this but I was curious to know if it is theoretically possible to somehow get passed this problem caused by the electron shell and by doing so would this allow th effective passage of matter through matter.

My thinking was that on the scale of the atom the amount of space taken up by actual particle mass is small compared to the space between the nucleus and the electron cloud so if the electron problem can be circumvented then all that space could possibly be used to pass through.

It would probably take some fanciful piece of tech based on unknown physics but i though i would ask!! Thanks.

You would have to deal with the electromagnetic repulsion. Heard of tunnel effect? –  jinawee Jun 10 '13 at 20:11

Yes, from quantum mechanics it is possible but very very unlikely or you have to wait a very very long time for it to happen. –  Dilaton Jun 10 '13 at 20:11

And even then it's more likely your atoms will tunnel into voids in the wall one by one before you jump through coherently. (Aside: my flippant answer to the title question is "Yes, if you throw them hard enough.") –  Chay Paterson Jun 10 '13 at 20:17
    
I know that the Pauli exclusion principal would prohibit it. I however don't know enough about quantum tunneling to answer this completely. –  Oral B Jun 10 '13 at 21:31

And, of course, the US Army tried to do just that. Major General Stubblebine's office also tried to kill enemies at a distance by thought alone. This is documented in various places (including the movie "The men who stare at goats"). See jonronson.com/goats_chapter.html –  hdhondt Jun 11 '13 at 1:40
