the Cosmic Microwave Background Radiation is purported to bend around massive cosmic objects by the gravitational lens theory. Metamaterial space fabrics prove what really happens to light is diffraction. The primordial big-bang radiation would not still be traveling around to reach earth, and be bent by huge galaxy clusters full of dark matter nonsense, all by gravity theories that take nothing into account by enormously strong and vast electric and magnetic fields.
Obtaining an exact solution of Einstein’s equations proves it’s entirely reasonable to discard the so called “gravitational lens” theory.
Mathematical imaginary relativity for gravity cosmology requires devising unseen dark matter and theoretical black holes. A societal virus plaques mankind widely misrepresented as the gravitational lens interpretation, along with the big bang theory. All true phenomena is electromagnetic in nature, that gravity theorists falsely mimic and analog by relativity.
