Bio-evolutionary Hypothesis for Absence of Green or Purple Stars

+1  

Take the evolutionary approach, and explain it by narrow spectra of survival-critical (evolutionarilyy rewarding) plants spectra due to narrow-spectrum chlorophyll and retinal.

So, various sources explain that human eyes have evolved to view yellow and green radiation [1], presumably because our Sun emits radiation primarily in those wavelengths, but that, perhaps is not a full story.

Here is a hypothesis I just thought of, that I had not known before:

  • Animals must have evolved specific sensitivity to chlorophyll green, because plants are a source of food, and so, we had evolutionary pressure to evolved sensitivity to very specific wavelength of green color.
  • Regarding the absence of purple stars, according to the Purple Earth Hypothesis, photosynthetic life forms of early Earth were retinal-based rather than chlorophyll-based, so early animals must have evolved the narrow-spectrum purple due to the same kind of evolutionary pressure.

What that would imply, is that we don't see green or purple stars not because they don't exist, but because of both biochemical and perhaps even neurological adaptions for narrow chlorophyl/retinal spectra. If these reasons are neurological more than biochemical, then one could say that we don't see green or purple stars because of psycho-optical illusion, similar to the hollow face illusion (rotating mask illusion), and say that green and purple stars do exist, we just don't see them the way we should, our eyes are biased.

This is an idea of a scientific hypothesis with an explanatory power to the question: "Why we don't see green or purple stars?"

因此,我们或许可以制作特殊类型的眼镜来纠正这种认知偏差。

这种眼镜必须通过将非窄带绿色和紫色浓缩到我们感知的特定窄带中来弥补对广谱绿色和广谱紫色的感知不足。这种补偿有点像减少绿色和紫色分布的标准偏差。

有了这样的矫正眼镜,我们就会看到绿色的星星和紫色的星星,如果它们真的在这些颜色上达到顶峰的话。

So, we could perhaps make special type of eye-glasses that correct for this cognitive bias.

Such glasses would have to compensate for lack of perception of broad-spectrum green and broad-spectrum purple colors by condensing the off-narrow-band greens and purples into the specific narrow bands that we perceive. This compensation would work a bit like reducing the standard deviations of green and purple distributions.

With such corrective glasses then we would see green stars, and purple stars, if they actually peak at these colors.
