RegularJoeRyugu asteroid samples contain all DNA and RNA building blocks, bolstering origin-of-life theories
inclementimmigrantHonestly, that’s a very, very cool discovery and now I’m thinking that means we can be somewhat confident that the building blocks of life can be found floating in space but yet we don’t see any kind of evidence of life in our decades of searching and that’s kind of sad to me and thinking of that instead of working.
Sample size of 1, admittedly, but we’ve had life on earth for 4 billion years. We’ve had life capable of radio communications for about 50 years. That’s .0000000014% of the time life has existed. Maybe it wouldn’t be a bad assumption to think that only that proportion of stars would have even had the time to get to this stage.
