"These beings, some of whom are more advanced than others, can control the “all permeating fluid” known as Vril."

"Spacetime is a somewhat slippery concept -- Einstein described the universe in four dimensions, combining the well-known three dimensions of space with time. Physicists now suggest that spacetime may itself be a fluid, a very slippery type known as a superfluid.
These new findings could help scientists in their quest for a theory of everything that explains how the cosmos works in its entirety."

“If spacetime is a fluid, then according to our calculations it must necessarily be a superfluid. This means that its viscosity value is extremely low, close to zero.”

"If spacetime is like a liquid—a concept some physicists say could help resolve a confounding disagreement between two dominant theories in physics—it must be a very special liquid indeed. A recent study compared astrophysical observations with predictions based on the notion of fluid spacetime, and found the idea only works if spacetime is incredibly smooth and freely flowing—in other words, a superfluid."
