Place a superconductor above a magnet and it will be perfectly suspended in the air, a phenomenon called the Meissner effect.

Not correct. Meissner effect is perfect diamagnetism, which is repulsion from all magnetic fields. Superconductors suspended above or below magnets are due to flux-pinning, which is only present in some types of superconductors.

A superconductor that has Meissner effect but not flux pinning is repelled by magnets and would not be stably levitated above a magnet, it would slide off to the side. It would not levitate below a magnet at all.

Given to hyperbole much? Any self respecting physicist knows that the "Holy Grail" of physics is the Unified Field Theory, aka the "Theory of Everything", Superconductivity doesn't even come close.
