  1. Yup. I have also noticed a lot of popular content about science in English talks to people like they never learned anything after mid school. Including books. More intellectually challenging content is more rare. P.S.: And most thing explaining photosynthesis simplify it so much that information becomes inaccurate. Like equating type of photosynthesis to colour of cells. There are greeen sulfur and non-sulfur anoxygenic photosynthetic bacteria, there are also many cyanobacteria which look purple due to lots of phycoerythrin, same with red algae. Also, colour depends on the exact proportions of numerous pigments they have, and that depends on lighting conditions, so the same culture changes colour under different conditions! So that is the topic I know. Over-simplifying it can give people false ideas. Maybe the same is true with other topics as well.

  2. Well, the idea that there is a flow of time or that we can change the future is probably also an illusion. And free will is an illusion.

  3. Nitrogen compounds under huge huge pressures can have interesting chemistry. Also, other liquid apart from water can be used. Some bacteria even on Earth live in liquid CO2 lakes on the ocean floor.

  4. At some things natural selection is better than any artificial creation by humans. That is why we can't repeat what natural selection did. A process similar to natural selection is used to train neural nets after all, because it is better at that than directly designing them. We humans are used to think our methods of doing things are the best for everything but that is not true.

  5. True. I study cyanobacteria which use far-red light 700-750 nm. So it is "far-red" not "far infrared".

  6. Many bacteria which use infrared are still green to our eye. Like green sulfur bacteria. Yet everyone talks only about purple bacteria...
