Universal centripetal acceleration. (Water in a bucket theory).

The universe is in a container tied to a long tether being spun around in circles, like water in a bucket.

So the tether is longer than the Universe.

It can explain why gravity drops with altitude:

The higher we go, the radius gets shorter but the tangential speed gets smaller and the expression m v

^{2} / r gets smaller.

Based on a couple of measurements we can calculate the speed of rotation and the length of the tether.

Unfortunately, the drop of gravitation with altitude is not linear, which drops the tether assumption.

Here we also have to ask: Where is all that happening?
