if i have a 1m diameter spherical core, rotating at light speed. What will we see on the outer circumference of the sphere... the surface of the 'ball'.... (assume it has a outer diameter of 10m)? The surface will be rushing by far faster than the speed of light, right?

What if this sphere is spinning inside a donut that is traveling in the opposite direction, also at the speed of light?

or if light speed isn't possible, with if the donut is going at 90% of it one way, and the OD of the ball is 90% the opposite way?

You'd see a black hole, because any mass traveling at the speed of light would have an infinite mass :)

Also, say, you can swing your arm at light speed. If your elbow hits light speed, will it break your arm, because nothing can go faster? Not exactly, because your arm will be bent in space-time. To your arm, nothing would be the matter, but to an outside observer in a different frame of reference, your arm would be bent.

If your core and donut are only traveling at 90% the speed of light, you'd get some pretty hardcore gravitational lensing, so from a distance objects around, in front of, and behind, will appear to crowd the object.

so there is a difference in what is being seen (b/c it's only light anyway), and what is physically happening to the molecules?

does this mean that light-speed science and theories are only theories of what is happening to the light reflecting off of objects (as viewed by a second object, with its own velocity relative to the subject object), and not so much how speed affects objects? like, really, the ball aint spinning, but the universe is rotating around it.... so nothing is happening to the ball.

Well, gravity affects the paths of photons, and your gravitational frame of reference can alter the way in which you observe those photons.
