Given:
  • An indestructible, stationary bicycle wheel the size of our galaxy.
  • An indestructible, stationary human observer positioned parallel to the wheel’s central axis, with a light source above him.
In this experiment, the wheel continuously accelerates its rotation.
Describe how this wheel would visually appear/perceptibly deform as it approaches and surpasses the speed of light. This is important because the rotational speed differs between the center and the edges.


My idols: Albert Einstein, Nikola Tesla, Richard Feynman, Jim Carrey.
Richard Feynman once said: "You must learn to doubt." (I allow breaking the laws of physics in this experiment.)
Also, I’ll add—I’m a "Yellow" in DISC psychology patterns, while most of you are "Blues."

Before you start telling me I know nothing about physics, please understand: I’m not a physicist. I don’t have a formal education in it. I learned/understood astrophysics in the way that worked for me.

Alright, now let’s add and relocate a copy of the observer to a point on the wheel where light is no longer visible. Would they still interact (the now-invisible parts of the wheel and the observer)?
I think not, because they would effectively exist in "different times" or "different spaces" (both terms seem correct to me).
English is not my nativ, most of it is auto translate.
This experiment, along with the previous post, was meant to inspire you—to offer an outside perspective.

However, when you do you lose the ability to use the laws of physics to work out what will happen - you're trying to apply the laws of physics after starting with the assumption that they don't apply.
That's not a starting point for a sensible discussion so this thread is closed.

People have been working with the physics of rotating relativistic disks for well over a century now, so googling for "Ehrenfest paradox" will bring up much good information.... And you'll find some good older threads here as well.
