Photosynthesis

To the NY Times Editor,
Your "Observatory" article in the June 21st, 2005 Science Times section talks about photosynthesis taking place near deep-ocean hydrothermal vents using the meager light that eminates from the lava deep inside these vents. The implication from the scientists' quotes in this article is that photons are only present in the visible light spectrum. In fact, photons are indeed produced in the infrared section of the electromagnetic spectrum (produced by the heat eminating from these vents) ... and for that matter across the entire electromagnetic spectrum ... even for radio waves and gamma rays. Therefore, who is to say that photosynthesis may not be able to convert photons at these different energy levels into biological building blocks?
Sincerely,
George W. Potts
