The worst that could happen in our lifetimes, I would say, is be a total waste of money and resources since no other reachable bodies have atmospheres suitable for Earth-based life. Beyond our lifetimes, and possibly beyond humanity’s existence, that life may be able to survive somewhere but any kind of evolution likely takes millions of years and long-term survivability may not let it see that day
I mean sulfur is an important component of life and extremeophiles can handle many conditions. When I heard things about possible life at venus it was generally the idea of microorganisms floating in the atmosphere.
Earth was very inhospitable for life for quite some time. In the future, it could become barren again. What’s to say that Venus wasn’t once harboring life? We don’t know anywhere near enough of its geology to even guess that.
Earth-like is a very broad term. If an organism has something similar to DNA or shared any kind of chemical processes it could be “earth-like”.
As an odd hypothetical example, there is a theory that fungi could potentially spread from planet to planet. Even with a billion or so years of independent evolution, fungi on Venus and fungi on Earth could still share some of the same traits.
Who wrote this shit? You can’t make an article that’s half about wanting a new name for your field and end it with “there’s a lot of ideas” without giving a single one. Garbage.
