Nope. FE theory explicitly rejects the spinning of the Flat Earth; otherwise, we'd all feel a southward "pull", which could be easily measured with an accelerometer. The Earth was formed by the coalescing of matter into a sphere.
Note that UA is really just a synonym for an invisible force because of Einstein's equivalence principle.
Could an FE actually detail the FE hypothesis for the formation of the Earth? It'd be nice to hear.
