given that there is a fastest speed at which anything can travel in our universe,299,792,458 meters per second, that seems to imply there may be a smallest distance in our universe, so first of all, is there any other evidence for or against a planck length being almost like a pixel through which energy can travel? am i wrong in thinking this?

and if so, i wonder, how many different directions could energy be transmitted out from a given 'planck-pixel' or unit of spacetime? is there some way that we could possibly test such an idea? have people already tried and to what degree?

so then that also makes me super curious, when it comes to an individual particle rotating, is there a smallest amount of rotation that can occur? or can the amount of rotation be infinitely divided? in other words, will we some day say that 0.00000009 (or whatever) degrees is the smallest amount of rotation any individual particle can move?

and conversely, is there a limit to how fast a particle can rotate? So basically, how many degrees of rotation can a particle spin over 1 planck length of time?

and how does rotation as i might tend to think of it, differ from rotation from the perspective of a particle, or 'spin', rather?
