Ken, for the millionth time, Newton PROVED that only a single force 
(gravity) was needed for a stable orbit. You have not disproved his 
proof, all you can do is assert that there must be a composite force.

Either PROVE Newton wrong (and get a ticket to Sweden!) or admit that 
you are wrong. Of course, you'll do neither, just falsely claim that 
there is a composite force causing the moon to orbit.

So no experiments have been done yet? So all you have is a hypothesis?

Well, your theory is wrong, then!

What? Tangential acceleration? The moon is orbiting the earth faster and 
faster??? I thought it was a constant ~29.5 days!

No, outward.

There are a zillion Youtube videos of amusement park rides with names 
like the Gravitron or Roundup that are basically centrifuges with people 
forced against the wall. They are forced against the wall, they don't 
slide around the inside faster and faster!!!
Here is just one video: https://www.youtube.com/watch?v=A0H7TYzcMaY

Some of them tilt so that the riders are upside down for part of the 
ride (forced UPWARD).

Wrong, Newton PROVED mathematically that only centripetal force 
(gravity) was necessary. What have you proved? Nothing?
