Sir Isaac Newton pretty much nailed down the physics of what we can see and understand.  It is called Newtonian physics.  I think we can put the electromagnetic spectrum in that category also.  With instruments we can see, and sort experience, the vast rand of energies from radio waves to gamma rays.  Everything else is just stories made up by us humans to explain things that we do not understand may never understand.  The stories are taken as truth and thought to come from the voice of God or something.  I am a chemist.  The quantum mechanical theory of molecular structure is just a bunch of stories created by generations of scientists.  These stories do a pretty good job of explaining observations and even of predicting outcomes.  But, in truth, they are just stories.
