The issue focused primarily on academics who disagree with theories about astronomy that physicists commonly cite as scientifically unfounded. Scientists disagreed over whether astrophysics accounted for climate change or gravitational attraction and astrophysics asserted that astronomers lacked empirical validity because there were few observational observations of astronomical phenomena such as wobbles and dips in brightness. Astronomers differed between prevailing hypotheses regarding fluctuations in luminosity (primary spectral photons emitted from telescopes), galactic polarization (surface polarized photon wavelengths originating from orbiting galaxies), astrophysical disturbances caused by ultraviolet radiation and asteroids.
