Light Wavelength Analysis Nets Purple Earth
Researchers here on the Oblate Spheroid, struggle to explain why microbial evidence throughout the Earth is varied yet so stratified.
The answer may come from the fact that the evolution of microbe life on the earth to date has come down to how these organisms were able to convert certain wavelengths of light.
Simpler structures on early Earth were able to absorb and utilize light from the green spectrum of visible light. If this is true, it suggests that the Earth would reflect light from the red and blue spectrums thus yielding a purple Earth.
Further, if this theory holds up, wavelength analysis may give astronomers greater understanding of the evolution of potential life through biomarkers on distant planetary objects.----
