Actually his idea is possible, white chlorophyl is not with out atmosphere.
are you serious? pigment that moves around with no energy source ad infinitum, that only disappears when you are looking at the dot? that means we could be looking at different parts of it, my spot wouldn't be dark for me, but it would for you. also remember the wood is BURNT. And it only does this if you arrange the ashes in a very specific pattern.
Still more likely than chlorophyl that is white.
It's impossible. One person can't view something as existing, while the other person can if they are both staring at the same time for an extended period of time. Also how would the pigment know where you were looking? Are you a wizard?
it could still absorb the UA and infared spectrum.
also it wouldn't be that hard to manufacture a white pigment.
You are retarded. Infrared can't penetrate through cell walls easily, and is a very low energy carrier. As for "manufacturing a white pigment" that is irrelevant, it is the problem of reflecting all wavelengths of light while still absorbing some that is impossible.
You might as well be claiming a batter batted 1000 this year yet he struck out some of the time. Being white and absorbing wavelengths are mutually exclusive, hence impossible.
that's assuming that the only wavelengths are in the visible spectrum.
Lrn2ultraviolet light
Also, I war arguing that forcing plants to grow white would be easier. now, if they survive, that is another story
Ultraviolet light is not a good energy carrier because it doesn't interact regularly with macromolecules. This means that it would pass through the chlorophyll more often that it would hit it.
The visible spectrum consists of wavelengths of light that easily penetrate our atmosphere and can be readily absorbed by large macro molecules (light receptors in our eyes do something not dissimilar to what chlorophyll does). It can be assumed visible light is the best light for photosynthesis.
Also, plants don't grow without functioning chlorophyll.
