Roughly 80 - 95% of the observable universe is "dark plasma fluid"?

"Roughly 80 percent of the mass of the universe appears to be dark matter: an invisible material that seems to interact with ordinary matter only through gravity, without emitting light or energy. Scientists cannot detect dark matter directly and don't yet know what it's made of, but they track its influence based on the motions of stars and galaxies. The presence of dark matter is necessary to explain the universe's current structure."

"An astrophysicist and cosmologist Dr. Farnes published a paper while at Oxford University with a novel explanation for dark energy and dark matter. His theory claims to explain the missing 95% of the observable universe by the existence of "dark fluid"."

"99.9 percent of the Universe is made up of plasma," says Dr. Dennis Gallagher, a plasma physicist at NASA's Marshall Space Flight Center. "Very little material in space is made of rock like the Earth."

""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".

"We also predicted other weaker dissipative effects, which we might be able to see with future astrophysical observations."

"Drag is a force exerted on an object moving through a fluid, and it is oriented in the direction of relative fluid flow. Drag acts opposite to the direction of motion and tends to slow an object."

"This same force acts on spacecraft and objects flying in the space environment."
