Why It Is — and Always Will Be — Impossible to See an Atom
The first reason why it is impossible — and what common sense indicates — is the size. If we cannot see even a microbe, which in comparison to an atom, would have the same proportion as a planet compared to a grain of sand, how would we see an atom? But this is not the main reason; after all, there are microscopes, using lenses we can see microbes, just build a microscope large enough, no?
No matter the microscope’s size, you will never be able to see an atom.
