Serious question about special relativity:

If you had an extremely strong material in a flat disc (OD = 4r) with a hole in it (ID = 2r) and it was centered around a non-rotating (no frame dragging) black hole (event horizon small enough to ignore) so that it oscilated up and down while spinning around, what would happen to the consistency of the disc itself?

I'm assuming the inside is traveling near the speed of light, say 0.8c.

The outside and inside edges are spinning at different rates, but due to time dilation they would start to stretch and disfigure, right?

If you assume it's strong enough to break apart, would figuring out the resulting angular velocity be just a simple integral involving the time dilation at each r', or is there more to it than that?

Let's see how I do.

1. Fuck if I know.
2. Hydrogen and helium, plasma.
3. Large impactor theory.
4. God fucking dammit. I know it in miles, 93 million.
5. I don't recall the long-ass versions and everyone knows the short ones.
6. Waves being emitted appear compressed or stretched dependent on the relative motion between emitter and observer.
7. 13.73 billion years, give or take one percent.
8. 73%
9. Drop to the surface.
10. Three point something light-years, from on some geometrical concept involving earth I don't remember.
12. He observed Jupiter's four largest moons orbiting around it, and...I don't know another way he proved heliocentrism.
13. The earth's pole is tilted at about 23 degrees.
14. The moon reflects sunlight, observers on earth can only see the intersection between the earth-observable hemisphere and the sunward hemisphere.
15. Photons (lol) strike a metal plate, generate electrical current.
16. As an object accelerates relative to a group of observers it gains mass and time in its reference frame slows. Moving any object with mass at light speed would require an infinite amount of energy.

There are others like that too.

I don't understand why we don't continuously build new shuttles as the old ones wear out. We already developed the fucking design and tested it to hell and back; there is always a need for satellite/station launch and servicing; why the fuck don't we maintain a working shuttle fleet as a matter of course?
