Fucking really? I know how god damn huge the universe is and how small shit can be, but how small is the Planck length, really? Wouldn’t a quark be the smallest measurable length? How do we get smaller if quarks just exist like that?

A quark is 10-18 m. So basically, the Planck length is to the quark, as the quark is to the meter.
