There are three related questions here:
Given the current limits of technology how far away are we from probing Planck scale physics directly?
It's well known, at least in some circles, that atoms were thought of in Antiquity; given the limits of their technology how far were they away from probing atomic phenomena directly. I'm taking atom here to be atoms in the usual sense, ie an atom of hydrogen or of Iron, and not in the philosophical sense of being uncuttable or decomposable.
Are we as far away from Planck scale physics, as they in Antiquity were from probing atoms? Or are we further away?
