1. Speed of Light is Additive; 2. Redshift

Very interesting TB forum post:

It is quite possible that some variable stars are actually [non-visual] binaries due to the light-bunching that results from the speed of light being additive: http://www.datasync.com/~rsf1/binaries.htm

I would say that it was Bryan G. Wallace who showed us back in the sixties that on an extra-terrestrial stage, light's speed is very much dependent on the speed of the source. When radar signals were bounced off the planet Venus from multiple radar stations around the globe simultaneously, he found that the delays of the signals from different stations suggested that these signals had the velocity of the earth's surface added to them ( http://www.ritz-btr.narod.ru/wallace.pdf ). Here on earth, the illusion of a constant speed of light emerges due to the influence of the combined electromagnetic fields of all the earth's matter. Down here, the earth's surface effectively takes over as the source for any light sources that are moving relative to it.

I reckon the speed of light being additive is evident on a cosmic stage too. imo it explains the time dilation we see in type 1A supernovae [more sensibly than expanding spacetime does!]. At the beginning of a supernova the luminous matter has a greater velocity than it does nearer the end due to the slowing effect of the surrounding interstellar matter. As a result, the light emitted near the start races ahead of the light emitted later, hence the light curve of the supernova is stretched out, more so the further away it is.

Another observation relating to the type 1a supernova's use as a standard candle can shed light on the variance of the speed of light. This is the observation that led the mainstream into believing the universe's alleged expansion is accelerating...

Type 1A supernovae are assumed to explode with the same absolute magnitude each time so their luminosities can supposedly tell us how far away they are independently of their redshifts. According to the mainstream, the redshift-distance relationship between different type 1a supernovae can therefore tell us about the universe's historical rate of expansion. If the rate was constant, a supernova's redshift would be directly proportional to it's luminosity-inferred distance. What we actually found though was that the supernovae with the greatest redshifts had lower luminosities than expected. The mainstream attribute this to an increased rate of expansion over time, hence the contrivance of dark energy. I, on the other hand, attribute it to the intergalactic medium's effect on the velocity of the light...

Light with a velocity greater than c relative to the intergalactic medium gets gradually slowed down towards c through it's interaction with this medium (known as an extinction shift). Redshifts are proportional to distance (imo caused by light's interaction with intergalactic molecular hydrogen), whereas luminosity is inversely proportional to the travel time of the light (rays of light diverge at a constant rate so more time for divergence equals lower luminosity). The further away the supernova is (measured by it's redshift), the more it's "super-luminal" light has been slowed down by the IGM, thereby causing it's luminosity to drop to a greater degree than it's frequency. No dark energy required.
