I guess that I can finally formulate it: the scale of the universe, from the entire thing down to an atom is about 40 magnitudes of size. I'm not sure how clos

  1 meter is about 27 orders of magnitude down from 100 Gly, and 12 up from 1 pm (approximately the proton radius). So we are closer to the small side.

  Aren't electrons about 3 orders of magnitude smaller than a sub-atomic particles like protons? And I can't find an estimate of the diameter of a neutrino easily from google (do we even have one?), but it seems like neutrinos are even smaller still. And I think we still have a lot to discover in this area. So maybe it's more like, about 40-50 orders of magnitude, but potentially much more as we explore the "extremely tiny" portion of the scale?

    Quarks are supposed to be tiny. Why is the Top quark so gigantic?

    As I understand it, it's believed that elementary particles (such as electron), don't have size.
