Seems I just found out I'm not real but relative.. Based on special relativity and the fact that I don't see out. ...My Brain has been keeping me in the dark. Believe our school system teaches Newton physics and should be introducing warped space time. Quarks. Black holes.. Feynman, Gellman.

Is change necessary?

education needs to start somewhere...often bite sized pieces that people can more readily relate to offers a convenient starting point. Nothing is quite what it appears to be...even solid steel is 99.99999...% empty space...

relativity takes some additional math and conceptual understanding and is not necessary to understand many everyday phenomena...

That's why electricty is often introduced with dc circuits which provide an introduction and usually ac circuits and elements, like inductors and capacitors comes later.
 
OK, so this has bugged me for a while about the equivalence principle and the black hole information paradox. If black holes "evaporate" via Hawking radiation, then they cannot exist forever. So, from my external perspective, watching the person fall in, they slow down, freeze, and redshift to "nothing," but never cross the event horizon. Does the equivalence principle say my perspective is valid? If it does, is it possible that that person really never crossed the event horizon? The...
In this video I can see a person walking around lines of curvature on a sphere with an arrow strapped to his waist. His task is to keep the arrow pointed in the same direction How does he do this ? Does he use a reference point like the stars? (that only move very slowly) If that is how he keeps the arrow pointing in the same direction, is that equivalent to saying that he orients the arrow wrt the 3d space that the sphere is embedded in? So ,although one refers to intrinsic curvature...
So, to calculate a proper time of a worldline in SR using an inertial frame is quite easy. But I struggled a bit using a "rotating frame metric" and now I'm not sure whether I'll do it right. Couls someone point me in the right direction? "What have you tried?" Well, trying to help truly absolute layppl with some variation of a "Circular Twin Paradox" not using an inertial frame of reference for whatevere reason. I thought it would be a bit of a challenge so I made a derivation or...
