To be honest, I didn't quote Expelled. I just said there was a movie made about this topic. I can't watch the video, but how did they settle panspermia? It seems to me the only thing they can now do with current technology is to give probabilities as to the unlikely nature of it happening. |
They haven't "settled" it so to speak, but the tests done haven't been terribly favorable. I'll quote a small section about how they are doing experiments and testing.
"After enduring a 12-day orbital mission and a fiery reentry, an unmanned spacecraft, Foton-M3, awaits retrieval in a field in Kazakhstan. The 5,500-pound capsule, seven-feet in diameter, housed experiments testing the lithopanspermia theory. The capsule contained, among other things, lichen that were exposed to the radiation of space. Scientists also strapped basalt and granite disks riddled with cyanobacteria to the capsule's heat shield to see if the microorganisms could survive the brutal conditions of reentry. This batch didn't arrive alive but the scientists believe that it was at a disadvantage.
"When compared to a real meteorite," says Rene Demets, the European Space Agency's coordinator for space biological experiments for this mission, "the heat penetrates quite deeply into our test samples".[47]
Future experiments
The Living Interplanetary Flight Experiment, which is being developed by the Planetary Society, will consist of sending selected microorganisms on a three-year interplanetary round-trip in a small capsule aboard the Russian Phobos-Grunt spacecraft in 2009. The goal is to test whether organisms can survive for years in deep space. The experiment will test one aspect of transpermia, the hypothesis that life could survive space travel, if protected inside rocks blasted by impact off one planet to land on another."
Not successful, but notice to all that they are actually doing some kind of testing and research, have predictions, criteria that need to be met and ways of testing said predictions and if it is proved impossible it will be thrown by the wayside. That's how science works.
As for Expelled, that's fine that you didn't quote it. I just don't like it when people try to give the movie legitimacy. I would do the same for Michael Moore Movies. Whenever you get home, check out it's wiki article. All of the scientists that were "expelled" for their beliefs are listed on the site with what actually happened in their cases. It's not even close to what the movie presents as fact of what happened. And most of them are working for the discovery institute, an overtly religious organization that's one sole purpose is to spread conservative christianity through the destruction of what they view as conflicting science through any means necessary.
