| A203D said: Yeah, i agree with you highwaystar, its most definitly not intelligent life. but some type of cells they've found that could indicate a link to cells in the human body or organic matter. a popular theory is that life on earth actully came from a comet that colloided into the earth and introduced foreign molecules into chemistry of our world. thus life evolved from molecules that came from the comet. i think it could be big if they've found evidence of this comet 'theory' happening somewhere else. therefore it could indicate the source of life in this world. the part of physics to do with large celestial masses is based on Eienstien's work, and based on his theory nothing travel faster than light. and the closest star to us 'Alpha Centuri' is 4 and half years away travelling at the speed of light, thus even if that were possible, based on the laws of physics as we know them, its impossible for a human being within their lifetime to travel to other solar systems and meet the 'aliens' there. suggesting of course that intelligent life does exist in another solar system in our galaxy. i think it could be an important discovery, if we have some pictures, etc. of some interesting celestial mass, perhaps they've found another planet like ours in another solar system. my rational behind this is the Voyager project. i dont know the details highwaystar, but perhaps you could clarify. i presume that the 2 spacecraft are still travelling away from us and still transmitting data, for the 20 years i think, maybe they've got some new data from those?? |
Yup, the Voyager mission will be running for another ten ears if we are lucky. I doubt they've given us any new data though, they're in deep space, they wont reach another star for centuries (by which time they'll have been inactive for years). Nothing's happening where they are.
As for panspermia. I can't say whether it's true or not, I don't think there's any conclusive evidence indicating that fact. But I think panspermia wouldn't have transported life. I think in the early solar system some of the comets that (hypothetically I believe) gave Earth it's water would have carried organic matter that could have played a part in abiogenesis, that would be as far as I would go. However, that would also indicate that the matter to create life is common throughout many bodies.
I think the fact that we've discovered organic matter on comets is significant evidence for this.
Also, if you could travel to another star at near the speed of light, you could travel to another star within a life time as time is relative (the faster you travel towards the speed of light, the slower your time ticks). It would be feasible for some hyper advanced alien race capable of travelling close to the speed of light (I would love to know where they got the energy from to do that lol) they could travel to many stars within a single life time. But because there are hundreds of billions of stars in the milky way I find it unlikely that they come across other intelligent life very often (if at all). The milky way would require a lot of exploration.
