Superfluidity is a state of matter in which the matter behaves like a fluid with zero viscosity; where it appears to exhibit the ability to self-propel and travel in a way that defies the forces of gravity and surface tension. While this characteristic was originally discovered in liquid helium, it is also found in astrophysics, high-energy physic...
