It is a solid that can spin without any friction. You could imagine a cube of ice where the water flows freely through the solid with no friction.
I wrote about quantum superfluid Bose Einstein condensate and it’s application in antigravity technology before, but what about a quantum supersolid state of matter?
Might a frictionless supersolid offer a significant source of energy for antigravity propulsion or novel energy devices?
They explain the state of matter as allowing for other non super solid states to flow through it begging the question as to whether or not it may eventually be utilized for more realistic holographic technology
