According to an article in a recent issue of Nature, bacteria could end up on microscopic dust particles, and with the help of the solar wind blow out into interstellar space and possibly seed life elsewhere in the galaxy. In related news NASA looks like it is about to announce that there was/is water on Mars, upping the chances that it once and possibly still does have life.
From Nature,
The Earth could be scattering the seeds of life throughout our Galaxy. Microbes could ride on specks of dust, powered by the Sun's rays, says William Napier, an astronomer at the Armagh Observatory in Northern Ireland.
A grain less than a tenth of a millimetre across would still be capable of carrying microscopic life, says Napier. And the pressure of sunlight can quickly blow grains this small out of the solar system. The same force might one day propel spacecraft through the cosmos.
Such a grain could travel about six light years from Earth in 70,000 years - far enough to reach other stars. We could be surrounded by a huge 'biodisk' of frozen organisms floating on grains of rock, says Napier, all of which can wander in and out of our solar system quite easily. "The solar system is as leaky as a sieve," he says.
Earth should spread its seed widest when we pass through a giant molecular cloud, a mass of dusty material from which stars are born. This has happened about five times since life appeared on Earth.
Each time, Napier estimates about three billion trillion microbes passed from Earth into the cloud. The chances of some of these finding their way to an Earth-like planet are quite high, he says. A similar process could even explain how the Earth wound up hosting life in the first place, he adds.
Maybe Mckenna's musing about mushroom spores traveling through space, and possibly being alien, won't sound so far fetched to a crowd of skeptics in the future.
Posted by: woodenpidgeon at March 2, 2004 12:15 AMImagine a project designed to spread living spores in all directions. The payload could be placed on a rocket, sent into the solar system and then dispersed for maximum effect. I doubt it would happen because of the cost, the time required and the lack of a chance to observe any outcomes of such a scheme.

very interesting addition to the debate.
Having read your comment, I agree that these new findings (or theory if you prefer) about life travelling through the cosmos in the form of dust particles casts a whole new light on Mckenna's ideas.
i mean it's harder for the average person like me to believe that life on earth was enacted by unexplicable mushrooms containing the seeds of human intelligence/conscioussness than believing that life forms (despite their origin) are cosmic travellers jumbing from galaxy to galaxy. Indeed, as Napier says, a similar process could explain how life appeared on earth.

There is also a diffreent and more compelling theory where Mckenna says that mushrooms expand our consciousness giving us the knoweldge to take us and our mushroom heirs into the cosmos. So his theory is that mushroom spores are spreading, not by some natural phenomona, but via advanced beings travelling the space ways. And that these advanced beings are smart precisely because the mushrooms spoke through their consciousness.
As crazy as this might sound to a scientifically trained skeptic, there is still no clear way to distinguish between information perceived in higher states of consciousness as arbitrary neuronal firings, or from some place else outside the brain. In all of John Lillys inner explorations, this mind-out-of-brain idea could never be scientifically validated one way or another, and because we are the observers doing the observing, via Godel's incompleteness Theorm there probably will never be a way to make that distinction affirmitively.
Ok George & Wooden, what do you guys think of the whole 2012-timewave-zero-end of-history-thingy??

So it's an insurance policy you're proposing? :-)
Chances are the simple bacteria capable of surviving in space are already abundant in the cosmos. Now figuring out a way to perpetuate complex life/intelligence, that is the real challenge.
Life is glorious, intelligence is even better.

i've lost you. is that when the fury of the singularity will be unleashed or is it something else? i'm vaguely aware of some kind of timeline proposed by vernor vinge [1] (or was it max more who first said that we have thirty years more or less till the critical moment arrives?) but then again my favourite transhumanist website's singularity countdown [2] says we're some 7,602 days (or roughly 21 years) away from the singularity boom.

George, so you've never heard about the Mayan Calender End-of History meme that's been around for years now? The date is Dec 21st, 2012. It's the end of the Mayan Calender. It was first picked up again by Jose Arguilles in the the 1980's with the whole new age harmonic convergence thing. He speculated that on this date, is when the earth would come into alignment with the "Galactic Zuvaya" and we would join the Galactic community of evolved consciousness.
Then Terrence Mckenna really took this idea and ran with it for the entire last 10 years of his life. He said that the singularity would occur on this date, that novelty would be become so extreme in the hours before this date, that we would escape history (space-time) altogehter and enter hyperspace.
How much do I believe this? Not sure, I live each day the best I can. :-)
Posted by: Paul Hughes at March 3, 2004 01:55 PMi had no idea. once again, i 'm told i've been living under a stone:-) perhaps the reason lies in my poor schooling - i haven't read any of mckenna's books, not yet anyway.
Posted by: george dafermos at March 3, 2004 03:40 PMGeroge,
Who told you that! let me at em! :-)
George, I have read your blog regularly since it's inception, and there is no way you are living under a stone. And besides, traditional schooling is overrated. I like your ideas, so keep shooting them my way!
