Hey, I'm new here, so I hope this hasn't already been posted, but I really need help with this question. There is a commonly used example to show how Einstein helped prove General Relativity through space curving due to different ratios in radians of a spinning wheel made to spin at the velocity in which it would feel like gravity was the only force acting upon you.
The experiment is as follows: one person measures the already spinning wheel's circumference and diameter from a stationary viewpoint, and finds the ratio to, of course, be 2pi. Now, the person in the wheel who believes he's at rest because he assumes gravity is acting upon and doesn't realize he's in a state of accelerated velocity does the same experiment, and due to the Lorentz contraction when measuring in the direction of acceleration, he will get the circumference to be greater than 2pi, as the circumference would be larger. Now, from this Einstein theorized that matter curved space to allow this change, and showed examples of how circle's circumferences change on curved surfaces.
My question is this: It seems like Einstein attributes the result of the Lorentz affect, which we know is due to accelerated motion, to a different cause, what we know of as General Relativity, or the affect mass and energy have on space-time. How is this attribution of affect possible? Is there a variable I am missing? Please explain this, it would be greatly appreciated.
