“If we could phase shift and match the atomic frequency of other atoms we could walk right through a wall.”
Um, no.
As fun as that pseudoscientific, Marvel comic bookish idea sounds, it shows a profound ignorance of the basic physics of atomic structure and the forces involved in the chemical bonding of molecules and compounds.
If you really want to understand the real science behind this, you might find a rudimentary course in atomic theory to be very informative. Be sure to include a basic chemistry course which discusses the composition of molecules and compounds (chemical bonds) and how they are the building blocks for larger structures, ie.: organic chemistry, biochemistry and biology.
There’s a whole lot more than just electrons going on in an atom.
