That's pretty interesting stuff. From the article it doesn't sound like anyone is doing a lab test to determine the lower bound for light intensity. Any reason not to? I mean, take a batch of this algae and shine 2x the theoretical minimum light intensity for photosynthesis on it. And another batch of algae with 1.5x, and 1.0x, and 0.8x, and 0.5x, etc.. And see which batches of algae die off? Devil is in the details, I guess?
- mmooss 2y agoI'd look at the paper and see who they cite for those numbers and theory.
- bozhark 2y agoWhat’s the control?
- SaberTail 2y agoThe control is daylight, where countless species of life survive on a daily basis. You are comparing the hypothesis that life can survive with very little light to the hypothesis that it needs normal amounts of light to survive.
- rightbyte 2y agoMaybe it is really hard to produce such weak illumination with accuracy?
- eternauta3k 2y agoNo, you can practically go down to single photons.
- abe94 2y agoExpanding on this, from what i understand there aren't too many labs (understandably) that are able to grow extremophiles in lab conditions. It would be great to run a bunch of experiments at various different conditions and see minimum and maximum on a variety of variables like salinity, acidity, heat, etc
