To better solicit more inline with what I'm trying to imagine, I'm editing my question, the original question is left below and removing the hard science tag, as that just seemed to cause issues, though I would like to get as close to reality as possible. Reading the site rules this seems the way to proceed, if not I do apologize. Mods do not hesitate to delete.
I do appreciate the feedback thus far.
The point I wished to get to was any affects a ring shaped object:
-spinning from relatively imaginable speeds (%20-30-50 Speed of light) to admittedly ridiculous speed of %99.999 C.
-in an area of unoccupied space, outside of any atmosphere but within the orbit of its host star.
-The dimensions of the object are at this point arbitrary, But for starters arbitrarily approximately 1 mile diameter(1609.34m), 10ft. (3.048m) thick in all axes, and a rest mass of 500 tones.
There have been mentions of Frame Dragging, which lead me to things like the Unruh Effect. However I am still unclear and if these would be connected to this device. Further what the visual or detectable effects these phenomenon would exhibit.
If external source of light strikes the object, I assume it will reflect blue anti-spinward and red spinward? I find it hard to believe that there would be no other detectable effects of a point of mass spinning near luminal speeds confined to such a small area. Especially quantum effects?
Ex: One of the fasted masses ever detected was the "Oh My God" particle.
The Oh-My-God particle (OMG particle) was an ultra-high-energy cosmic ray detected on 15 October 1991 by the Fly's Eye camera in Dugway Proving Ground, Utah, U.S. At that time it was the highest-energy cosmic ray that had ever been observed. Although higher energy cosmic rays have been detected since then, this particle's energy was unexpected, and called into question theories of that era about the origin and propagation of cosmic rays.
The particle thought to be a proton or neutron would/could this device throw off particles similar to this from impurities in the rings construction? Or from interaction with solar wind or dust particles? collision with micrometeorites?
Is it possible for inertial mass to create singularities or singularity like effects? However interesting this is I am more interested in the "I don't know what I don't know, so how do I ask" questions. Which I guess is considered fishing. :(
Finally, if anyone is interested, the pretext to this story is this.
After sending several fly by probes to a nearly solar system.(Epsilon Eridani) An early colonization ship was sent. on approach even before reaching the planet this anomaly was detected. Picking out a 1 mile wide object from a random point in the solar system requires some justification. And describing the object as they approach will also be a challenge.
A ring, at this point constructed of perfectly rigid "unobtanium", and size/mass dependent on what the effects are. For starters arbitrarily approximately 1 mile diameter, 10 ft thick in all axes, and a rest mass of 100 tones.
What would an observer see and be able to detect in the local area of space as the ring is spun up to %99.99 C? Would the geometry (height width thickness) of the right contribute to these effects? Any type radiation? Warping of spacetime? Gravitational anomalies? At what point would a ring like this fly apart from centrifugal(?) stress if constructed of the strongest conceivable material we know of, say nested carbon nanotubes ~150 gigapascals? Or is some kind of super science unavoidable to keep the ring together long enough to see anything interesting?
edit this ring is located in space, in an independent stealer orbit.
