    Great point about not needing to define life when you are looking for it. Find some anomalies and work from there!

      I posted above that it irritates me how snobby and @n@l retentive our species (especially scientists) are with DEFINING things. Instead of being obsessed with EXACT DEFINITIONS of things we should just see what is there and just accept that things are what they are. Scientists still have not agreed on whether VIRUSES are technically life or not.

    One thing I MOST respect about this guest is that he ADMITTED that he had no one specific DEFINITION for life. We as humans are too obsessed with DEFINING things and we get very @n@l retentive about it and reject anything that does not perfectly fit how we have decided to "define" something. In the real world things just ARE THE WAY THEY ARE and the universe does not give a d@mn how we choose to "define" something.

    Lol JMG i do love that you’re so open about your microbial universe biases. I definitely agree with you, and believe it makes perfect sense. I hope that within my lifetime we’re able to take microscopic pictures of both Mars and Venus and hopefully find life on one of the two. It’d be even cooler if we found life on Titan tho, both literally and figuratively.

    Actually, it seems to me that there is a basic principle that would make it much easier to theorize about potential environments that life can exist. The only difference between microscopic life and multicellular life is just the fact that there are fewer organic processes going on inside microscopic life so therefore there is far less of a likelihood that there would be anything about a particular environment that would make it impossible for microscopic life to exist. That being said, microscopic and multicellular life are fundamentally the same and therefore the only thing needed to allow for multicellular life to exist in any environment where microscopic life can exist is specific adaptation to that environment. So it just makes sense to assume that you could find advanced multicellular life in any environment that microscopic life can exist, and buildup a library of possible life supporting environments based upon environments that microscopic life can exist alone with the assumption of the possibility of more advanced life.

    It would be arrogant to think not. I’m positive there could be life out there that consider water a very common resource and not necessarily valuable because of their distinct biology.
    Maybe they’ve got bodies made from stuff that takes billions of years of evolution or fabrication that no longer needs water and can utilize other source of matter that’s more efficient; much like car needing gas or electricity.

    You know the frozen block of pee and poo that the passenger airplanes contain? Well, a starship's block would probably be dehydrated (water reclamation), and super dense (compressed for storage). But... eventually, it would build up to the point that they'd have to shoot it off into space... billions of years ago, and accidentally on a collision course with our solar system. What if THAT'S what seeded life on Earth? Panspooia, IOW.

      That's very funny! 😂 but I imagine on a starship, on a long voyage, ideally you would need to recycle everything. Poo is actually a valuable source of organic matter and nutrients for your food, it's your fertiliser and compost! You need to imitate earth's ecosystem, including bacterias and other decomposers. To recycle all that. If you throw away into space that matter, you will need to mine those elements elsewhere.
      Everything has value in space, even poo! 😂

      Probably can't realistically stop the intrinsic brightening. You're gonna need a method of lifting helium from the core of a star for that. What you can do is buy time with star shade, but that is a stop gap. The sun will win in the end.

I'd be very surprised if we didn't do this; and given human greed, I think it's more likely that, in the future, we'd have to worry about too faint a sun, not a too bright one.

      And the question of what for us are industrial chemicals that tend to be horrible and toxic.. what happens then with volcanism and continental/crust plate tectonics etc creating voids or tubes, cave systems and fissures that are otherwise geologically stable. They could produce biomes ripe for biologically stable niches to develop, also with the question of the possibility of stable biochemistry in a particular cloud layer given specific pressure and temperature.. isn't that the same question as oceans? Like deep ocean salt pools, do deep ocean acid pools also form without mixing with the other liquids of a given ocean. Whatever lives and dies above drops potentially useful byproducts into those pools where otherwise food might be too scarce
