Starting from the basic assumptions and equations of Big Bang theory, we present a simple mathematical proof that this theory implies varying (decreasing) speed light, contrary to what is generally accepted. We consider General Relativity, first Friedmann equation Friedmann-Lema?tre- Robertson-Walker (FLRW) metric for Comoving Observer. It shown explicitly Horizon Flatness Problems are solved, ...
Activity rhythms in 24 h light-dark cycles, constant darkness, and constant light conditions were analyzed in four different Nasonia species for each sex separately. Besides similarities, clear differences are evident among and within Nasonia species as well as between sexes. In all species, activity in a light-dark cycle is concentrated in the photophase, typical for diurnal organisms. Contrar...
PURPOSE This study was conducted to test the hypothesis that phenyl-N-tert-butylnitrone (PBN), a spin-trapping agent known to cross the blood-brain barrier and protect the brain from ischemia-reperfusion injury, is incorporated into the retina after intraperitoneal injection and protects photoreceptor cells from the damaging effects of constant visible light. METHODS Albino rats were injected...
