Alright, /sci/. Redpill me on desert varnish.

>> No.10762372

>Redpill
wtf does that even mean?
You want me to tell you it's just wind/sand erosion? Or that it's secret message from UFOs? Or that it's a conspiracy from the bogs to artificially inflate the price of store brand varnish?

Seriously, I think these red pills are highly addictive drug that kills brain cells. We should ban it.

What I'm trying to say is that this stuff is criminally understudied like basically all microbial life even though they make up 95% of Earth's biomass and have more species than the multicellular ones.

But then why is it still considered mysterious by science? It seems that no one has actually found out what the microbes are like and how they work.

One thing I dont understand about the shadow biosphere is couldn't you just look for chemical byproducts that don't have a natural or man made origin and work backwards?

>>10762860
I think estimates are that about 5% of methane are unaccounted for. Also, some byproducts are assumed to come from natural sources because we don't seem to know otherwise. A lot of microbes seem to metabolize very slowly, though. Which is why it is not possible to cultivate them - the usual method to find out what they need to live and what chemicals they produce.

Explain the process needed. As far as I know we still use petri dishes and PCRs for detecting life which usually just works on regular life but not a different form of microbes.
