Algae-like structures inside a Sri Lankan meteorite are clear evidence of panspermia, the idea that life exists throughout the universe, say astrobiologists.

    Very exciting if this holds up.
    I'm of the belief there is a lot of life out there and panspermia may be how it gets started on worlds with the right conditions. I very much look forward to the day we have undeniable proof of life off of this planet.

    Even if it's proven that life on earth first came here from space, it still doesn't answer the question on how life started.

    We are actually getting closer. One thing we recently learnt was that water molecules will naturally form themselves into a lattice work resembling the same structure as many protiens. All that is needed are some long chain hydrocarbons to come along, dissolve in water, and the water lattice will form them into protiens.

    If comets do transport life around the galaxy we may never know the origins of life. Maybe it's that comets don't actually transport life itself, but the seeds for life.

    One has to wonder if the comet drivers are Teamsters?

    No he didn't. The dinosaurs all fell overboard from the ark and drowned.

    Exciting News, if it holds up. It may not support Panspermia, but it would show that Life may exist elsewhere or that it isn't all that rare.

    From the article...
    There are other explanations, of course. One is that the fireball was of terrestrial origin, a remnant of one of the many asteroid impacts in Earth�s history that that have ejected billions of tonnes of rock and water into space, presumably with biological material inside.

    Source or STFU. :lol: Seriously, I'm intrigued--do you remember where you heard that?
