  • Almost assuredly not, but we know so little about abiogenisis, its entirely plausible to consider that there may have been multiple origins of life on earth. The nature of cellularization, and DNA first versus RNA first models for life (or perhaps even some other “3rd” biomolecule? maybe surface level interactions on clay?), or even RNA only models. It may well be that there are other sources for abiogensis that are extraterrestrial, but that doesn’t overcome things like the concentration dilemma (you need some biophysical process to concentration “enough” of these interesting biomolecules to do meaningful stuff).

    So extra terrestrial things that stand on legs and have heads and eyes? Almost assuredly not. But it may well be that we’ve been repeatedly (or continuously) colonized by extra-terrestrial bio-molecules. I still hold out for some missions to features like Pluto where there is obviously a kind of deep-ice geochemical cycle happening (freeze-thaw based on coming close/ further to the sun). In these cycles there might be opportunities for basic biomolecules to form and accumulate. Slam a big chunk of it into a planet that is at least cool enough to have liquid water, and a geochemical cycle, that might be all you need.















  • Yeah idk. This was a criticism that I brought up of the fundamentals in lemmys structure early on: it selects for, effectively, clones of “whole reddits”, when it should be set up to support more balkanized instances.

    Basically, lemmy.ml’s c/Politics is functionally redundant to .worlds c/politics; but thats by design.

    What I think would be better would be adding tagging and taking federation a step further. Every post needs a ‘tag’; we steal that part from mastadon. It can have many, but it needs at least one, say #politics in this example.

    Then, on instances, federation happens both at the instance level but also at the community level; communities can federate with other communtiies. But all posts get #tagged on the way in the door. Communtiies can then federate or defederate at will, and if neccessary, a community can “branch”; for example, maybe they want to split off US politics from politics; then you grab all the posts with the #US.

    As far as an abuse vector. Thats just hang wringing. IF your mods are that abusive for a large sub, you’ve got way bigger issues. Which, if it did ever happen, is something that “forking” would solve. Mod on a power trip? No problem. Fork the community.



  • Lemmy & the fediverse needs to be more modular.

    We need… something like a “transfer, merge, fork, split” for communities.

    For example, if these guys are just going to nuke that content, another instance should have the opportunity to either fork it, or merge it with another community. Its mostly the same stuff as would have been in c/Politics here.

    And what it does now, is it puts even more editorial power in the hands of fewer people (ones that ml probably) don’t vibe with.

    Classic boneheaded decision.
