Saru Posted June 17, 2013 #1 Share Posted June 17, 2013 Distant solar systems with more than one star could be good places to look for habitable worlds. Luke Skywalker would be proud. Planets like Skywalker's fictional home of Tatooine in the "Star Wars" movie series might have more potential for habitability than planets in other systems, research suggests. Read more...

Junior Chubb Posted June 17, 2013 #3 Share Posted June 17, 2013 (edited) if there's a bright center to the universe, you're on the planet that it's farthest from... Great article to read, even though Tatooines 'twin suns' are actually our sun and moon. Edited June 17, 2013 by Junior Chubb Link to comment Share on other sites More sharing options...
Frank Merton Posted June 17, 2013 #4 Share Posted June 17, 2013 I can picture some astronomer on Tattooine saying, "Don't expect life on the earth. Its sun is solitary so it would get too much solar radiation" 2 Link to comment Share on other sites More sharing options...
marcos anthony toledo Posted June 17, 2013 #5 Share Posted June 17, 2013 Finding life in this galaxy is becoming more possible with each new extra solar study. Link to comment Share on other sites More sharing options...
Frank Merton Posted June 17, 2013 #6 Share Posted June 17, 2013 Finding life in this galaxy is becoming more possible with each new extra solar study. It's hard to be more possible than possible, and that is about what it is. There are probably somewhere between a million and a billion planets and moons that in theory could harbor life, which is what we could say about Venus, the Moon, Mars, Europa, Titan, and maybe a few others in our system, in addition of course to the earth. Unfortunately, or maybe fortunately, the ability to have life on them is but one uncertainty we have to consider. Other uncertainties are the chances of life evolving, the chances of life surviving several billion years, the chances of it evolving into complex forms, the chances of it evolving sentience, the chances of it evolving consciousness, the chances of it developing advanced technology, the chances of it not destroying itself, and the chances of it not finding another universe. If any of those, even one, has a value approaching zero, then the product will be close to zero. That's arithmetic. Link to comment Share on other sites More sharing options...
Occult1 Posted June 17, 2013 #7 Share Posted June 17, 2013 Interesting discoveries because with the number of binar systems in our galaxy the odds of finding life are greater. Now we have a confirmation that various conditions and not only those of the Earth are suited for life. Link to comment Share on other sites More sharing options...
+DieChecker Posted June 17, 2013 #8 Share Posted June 17, 2013 And to think that just a couple years ago, the experts were saying not to even bother looking for planets in binary system, because they probably would not form there. Link to comment Share on other sites More sharing options...

Life could be rare, but even if only one planet out of a trillion have life, there's still millions to billions of planets that have life. Thinking we are the only life in the universe is like thinking we are the centre of the universe. It's that human need to feel unique, I have no doubt some people believe we are alone and that gives them great pleasure. That we are the only sentient species. I honestly think it would just be an awful waste of space and monumentally boring if we are the only life out here. Link to comment Share on other sites More sharing options...
spud the mackem Posted June 17, 2013 #10 Share Posted June 17, 2013 We are one of a million or more species on this planet,some of which have been here a lot longer than us,and a lot can survive in extreme heat or cold that would kill us,so why do we think we may be alone in the universe,there could also be other life forms not based on carbon,we cannot be alone,but cannot at the moment prove it,but one day ?????

+DieChecker Posted June 18, 2013 #11 Share Posted June 18, 2013 I think dolphins were just recognized as a sentient species in India....

Waspie_Dwarf Posted June 19, 2013 #12 Share Posted June 19, 2013 I honestly think it would just be an awful waste of space and monumentally boring if we are the only life out here. The universe does not care about what humans think is boring or a waste. It is what it is. The good thing about science is that it's true whether or not you believe in it.Neil deGrasse TysonWhether we are alone or part of a universe teaming with life is not a result of human desire or sentiment, hope or fears, it is a result of the laws of nature. Human judges can show mercy. But against the laws of nature, there is no appeal.Arthur C. ClarkeTo quote Sir Arthur again: Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying.Arthur C. Clarke 1 Link to comment Share on other sites More sharing options...
Frank Merton Posted June 19, 2013 #13 Share Posted June 19, 2013 While it seems impossible that we are the only life out there, there are reasons to think we may be the only intelligent, sentient, technological life we are likely to ever encounter. Indeed, I remember seeing estimates that there might be only one occurrence of us in the entire observable space. I'm not so sure that is a boring prospect. Think of all the worlds we will have no moral qualms colonizing. On the other hand, if life is common, these worlds may well be off limits for both biological (mutual poisoning) and ethical (cutting off potential evolution) reasons.

+DieChecker Posted June 19, 2013 #14 Share Posted June 19, 2013 (edited) Even if Earth is the only life right now. It will spread. Even if life has to wait till a gigantic asteroid hits the Earth and fragments with microorganisms go flinging out and it takes a million or a billion years for one to fall on another world, life will spread. Whenever we send a man made device out into space, it is a chance for life to spread. If planets are as common as is being infered these days, and if we can assume that a star would attract intersteller debris, then we can assume that eventually most big bits of matter will fall onto a planet and eventually some of those microorganisms will catch hold somewhere. The odds are long, but the time to do it is even longer. Modern estimates are that the Milky Way galaxy is about 14 billion years old. And estimates are that star formation will continue for 10^16 years. Or another way of looking at it is that the Milky Way Galaxy has been around for 1/500,000th of its lifespan so far. That is a LOT of time. It is almost the same ratio as one hour in the life of a person that lives to be 100 years old. The entire life of the galaxy so far is only the first hour after a baby has been born. Edited June 19, 2013 by DieChecker Link to comment Share on other sites More sharing options...
