Panspermia

Hey, this is interesting ...

Just came across a paper on lithopanspermia in star clusters. Due to the closer distances, it's much more likely that life can spread from one system to another. In longer-lived clusters, life originating on one planet could possibly seed itself to a majority of the other systems in the cluster through the process.

Lithopanspermia in Star Forming Clusters

Numsgil:
That is interesting.   It directly follows  up the paper I posted.

It still primarily limits the development and spread of life to very local neighborhood though.

-venom-:
ahhh I have heard of this theory before and are not agenst or with it but for the sake of arguing:

this would have taken place billions of years ago so who is to say that billions of years in the past we were close
enof for this to have taken place and the key word is unlikely so that means it is not totally implauseable
but maby we are one of the very very tiny few (compared to the imenseness of the universe) planets that life could have spread to from another solar system.

Recently some cientifics found life in a mine that had been buried way down the earth there for millions of years. It was using chemical compounds to extract energy. It's not that hard to imagine an huge meteor sending some deep rocks into space. There's that great crater in Mars, 7km deep... the meteorite impact was so big it actually created Olimpus mons and several other volcanoes at the opposite side of the planet.

Life travelling through the solar system seems plausible (mmh, gotta send a mail to Mythbusters, maybe with lots of dynamite and a big rock they can test it...), but also between stars if you consider the sun isn't static, but orbiting the galaxy each 200 million years or so. Perhaps the space out there is seeded with bazillions of rocks with bacteria and the Earth just catched some in the past.

Numsgil:
However, if you look at that article I posted, the chances of ejecta from one solar system arriving at another are so unimaginably small...  The article Elite posted counters with the suggestion that it could be primarily used in stellar nurseries, where there's far more chance of sharing ejecta.

It's an interesting idea, but so obviously wrong.  It is the Unbegotten Source, the Demiurge Ubbo Sathla that spawned the first single celled life on our primordial planet.  And one day all life on Earth will once more return to his lifeless pseudopods.  Of course, that's likely to be after His awkening from his lifeless sleep.
