Hahahhahaha! Poor old Jerry doesn't know the difference between an inertial frame and a rotating one. Rotation is absolute Crank. For every rotating frame, there is a corresponding nonrotating one. To the carousel, the ground not rotating. The pill bottle appears to rotate in your rotating frame, just as the emission point does in a ring gyro. >Jerry > Henry Wilson... ........Einstein's Relativity...The religion that worships negative space.

If you let go of your pill bottle with the carousel in free fall, then INITIALLY, it appears to you as if it were accelerating radially outwards from the center of rotation. That is the effect known as "centrifugal force". If you drop your pill bottle on the ground, then INITIALLY, it appears to you as if it were moving tangentially away from you at a constant rate corresponding to the velocity at the circumference. NEXT QUESTION. If the carousel is mounted on a jet-powered car that is racing northwards at 1000 miles per hour and you drop the pill bottle on the ground when you are at the northern-most point of the circuit, how does the pill bottle appear to move relative to you? If you drop the pill bottle on the ground when you are at the southern-most point of the circuit, how does the pill bottle appear to move relative to you? For the emission source to move "backwards" as you claim it does, the emission source must be, ahem, "stationary" with respect to a non-rotating frame that is tied to the center of rotation of the carousel. In other words, you believe that every rotating carousel is tied to its own absolute frame, whatever in heck that is supposed to mean... Jerry

That >is the effect known as "centrifugal force". OK forget your pill bottle. ...but don't forget to take your pills... You are riding on the edge of the crousel. At a certain instant, you fire a paint ball at the ground. What do YOU think happens to the spot? >If you drop your pill bottle on the ground, then INITIALLY, it >appears to you as if it were moving tangentially away from you >at a constant rate corresponding to the velocity at the >circumference. Don't be difficult Crank. You actually know what the experiment is. >NEXT QUESTION.

That's the whole basis of SR's sagnac explanation..
