Isn't the force acting on the liquid in a rapidly rotating cylinder indistinguishable from the gravitational force acting on the liquid in a cup on your table? If we could somehow turn a knob that increased the gravitational field of the planet supporting the table with the cup of liquid what would we see? The table would collapse, the cup would break spilling the water, the planet would begin to shrink and temperatures would begin to rise. Continue turning the knob and molecules would break down, electrons would break loose and we would have a plasma, a fourth state of matter. Eventually on our way to the singularity we would see neutron-degenerate matter and maybe other stuff. However, none of these states of matter would be considered solid in the usual sense.
