Welcome.
but incorrect. Light VELOCITY is constant (unless it's near an event horizon). Time absolutely is NOT constant. Refer to Einstein's general and special theories of relativity.
the bifurcation of red/blue non-polarized sunlight thru different aqueous solutions is nothing meaningful. It's optics. To correlate that with "red and blue" veins and arteries in the homosapien circulatory system to find some hidden compelling meaning is a non-sequitur and false equivalency. Sure, one frequency of light may fall to the left but so what? What if you view the circulatory system from the other side? Then the analogy is lost.
