Suggestion[edit]

Suggestion: Replace the nanotechnology link with one to the more-to-the-point less-hypey article on molecular assembler which uses only credible sources...

Panspermia[edit]

Noticed a statement about the panspermia hypothesis in the intro, although at present there is nothing about panspermia in the body text. I don't think this is relevant as it stands.

I wouldn't be opposed to having something in the body text exploring the relation between panspermia hypotheses and alternative biochemistry hypotheses. Jonathan Lunine has argued that finding microbes on Titan with radically different chemistry would imply they were NOT related to Earth life via a panspermia mechanism such as meteor transfer. Conversely, the more sweeping versions of panspermia hypothesis would seem to rule out radically different chemistries — if living things are all over the universe, and they are all related to each other, then their biochemistries would presumably be rather similar...

As with everything in WP, if we're going to discuss this in the article, we will need citations. Not just about panspermia itself, but about the relation between panspermia and alternative biochemistries. Kalidasa 777 (talk) 00:54, 19 March 2015 (UTC)

I think you are right, and I too was tempted to delete it last week. Besides, if life on Earth was transported here by some panspermia mechanism, it cannot be used to explain "alternative biochemistries" because there is none of those on Earth. BatteryIncluded (talk) 01:01, 19 March 2015 (UTC)
