experiment earth spinning or stationary
« on: March 01, 2023, 01:35:11 PM »
My first language is not English.
I want to hear your opinions about my idea for an experiment.
For this one needs some drones with camera.
I want to put a drone in the air , and film a large object , a bridge , or a big building.
If the earth is spinning , and de drone films an object the object should move/spin.
The drone because it is airborn would not spin.
The drone must 'hang' in the air in the same position for at least 10 hours.
I maybe need more drones because of battery capacity.
So , if the object does not move/spin , the earth is stationary.
If the object moves/spins , the earth is mobile/spins.

You missed a critical factor here: in any model in which the earth moves, the air moves with it. The reason is that as the air hits the Earth, it gains the Earth's momentum, being pushed along with it. The air moves with Earth. If air didn't move with the Earth, it would create wind speeds in the thousands of miles per hour. For a good source here, check out What If? (This specific question is only in the first book, and wasn't posted online. Long story short, everything not next to the poles is wiped off the map.) The drone would hang in the air, but the air is stationary relative to the earth, because of friction.
