Whenever we search for life, we're searching for 'life as we know it". But are there alternative options? Non-carbon based life? Or life that doesn't use water as a solvent? It turns out, things like that can be as close as on Venus. Figuring it out with Dr William Bains.

"We're science fiction friendly" :) It was a great interview, but I have my doubts about a return sample from Venus. That's VERY hard. But I definitely love Venus and I find it very stupid that we haven't sent more missions there, especially since it's cheaper to send them there in terms of delta v. I don't know how space agencies has resisted the temptation to go there for so long.But I really appreciated Dr. Bains explanation about why water is needed for life and how it could be replaced by other solvents. Super interesting.

Right, fire meets the metabolism requirement (struggle against entropy...). So a better definition of life needs to also include something about processing and replicating information about how to do life. Fire doesn't process information (recipes) about how to build a good campfire.

whether there is life (what ever we mean by that word) on Venus or not. I think it is pretty clear, that we have big gaps in our understanding of the chemistry of Venus atmosphere. So it is time to send an atmospheric probe, a balloon or perhaps even a blimp there to begin giving us answers. or at least leads us to ask the right question.

@smokeyninja9920 5 ай бұрын

Probes have been sent to Venus, due to the inhospitable environment, they tend not to last very long in the lower atmosphere or on the surface. Consider the sulphuric acid in the atmosphere of Venus for why ballons and such aren't usable.

If it was a repeating and identifiable signal it would depend on the strength of broadcast the length of the repetition and the amount of scattering betwixt source and cypher. Of course they'll probably use neutrino transmitters as they go through stars just fine :).

Just finding chemicals associated with life will not (from my discussions) convince most biologists.

Why do many space nerds push for colonizing Venus (in upper atmosphere) when there's no way to acquire resources locally (other than what you can extract from atmosphere), so you'd have to ferry all supplies from Earth and basically this colony wouldn't be more practical than any random space station? Do they just not consider logistics, or am I missing something?

One major advantage of living in the upper atmosphere of Venus, versus a space station, would be gravity. A vessel supported by balloons and sitting above the thick atmosphere would have gravity, which is difficult to make artificially. Gravity is important for humans and any life they might bring along. Venus being about the same size as Earth should be even better than Mars or our moon.

I'd define life as having three properties: 0: Maintain low entropy within the system through interactions with the environment (i.e. metabolism), 1. Replicate, 2: Process information about how to do 0 and 1. Something like that. My point being that the definition doesn't need to be overly biased by "as we know it". That being said, it is possible to argue the hypothesis that life is gonna be carbon and water based, without that argument being unimaginative or thinking inside the box. A simple definition in terms of entropy allows for a pretty broad range. I mean, who knows what's going on in stellar plasma, etc. But if you constrain the search to chemistry, you've got a very finite set of ingredients, of which carbon happens to be the only viable candidate for both structure and flexibility necessary for life. We can enumerate the short list of alternatives, and it's fairly trivial to rule those alternatives out. There could be some debate about alternative solvents, but that's a finite list too, and water is hard to beat.

No they don't, they get it from hydrogen sulfide.., they react it with iron and other metals, eventually the sulphur compounds get turned into sulfuric acid. On a different video of his I suggested maybe there was life converting HS into HSO4 but unfortunately nothing evolved to photosynthesize turning the CO2 into O2 etc. hence it killed itself.(On Venus) If something could live on or photosynthesize SO3 , it would be a great candidate for terraforming!

Statistics. There are so many different ways to carbon could be put together and so hard to control, silicone puts itself together in much more limited number of ways so it's predictable and easier to engineer. But there are fantasies of using carbon to make things like Moray patterns between layers of graphene , just changing the angles between the sheets slightly, make everything from an insulator to a superconductor with all kinds of metamaterial photonic crystals inbetween, and that's just from sheets of graphene, Think of organic light-emitting diodes and transistors that operate on the molecular scale like the molecule for the dye perylene green! Carbon does have so much more potential but because it could be put together in so many different ways but it's not like we can just use our hands to put the carbon atoms where we want , it's so much harder to engineer.

Lets just imagine that we found some kind of Lichens stuck to the side of rocks on Mars or Venus; it would be a big deal right? I mean we spent enormous time and money looking. So what happens then?
