    Do you think its possible for a planet like earth to be revolving around the sun at the same distance from the sun on the opp. side of the sun and at the same speed (well kinda has to... to stay in orbit). so we can't see it?

    This is the wierdest question.

    I believe that life, as we know it, isn't (how can I say this..) universal.
    Probably there are still plenty of unknown chemical elements wich allow life (as well as intelligence) to develop in other (and even harshest) circumstances.

    Do I believe we're not alone? Certainly! :)

    "Closer than we think?" - I have no idea.. :$

    jwong, that could have worked if we were living in the begining of the space age or earlier. today its impossible. our sonds/probes would have found it

    There is no planet there. firstly, if similar to earth then there would be anomalies in the orbits of the other inner planets - and we do not see this.

    Secondly there are a number of man made satellites in orbits around the sun - I think something would have shown up.

    Oposite side of the sun??? The Earth goes round the Sun, it completes a full cirlce. The earth is on the opposite site during winter. What are you talking about???

    Starry eyed guy, jwong is talking about a planet orbiting the sun at the same distance from the sun as the Earth, but on the opposite side of the sun. In that case we should be unable to see, since it would be concealed by the sun.

    It is a delightful idea, jwong, and one that has been used in a number of science fiction stories. Unfortunately it is not feasible. As others have pointed out we would have detected it other space probes, or through its effect on the orbits of the other planets. Even before the space age calculations could show that because of orbital variations it could never remain in a stable position exactly opposite.

    Yes, I believe there is another Star somewhere in the Universe which is the same distance ( or nearly ) to the sun as ours, with all the millions of stars that exist there has to be a match, theres more chance of that happening than winning the National Lottery.

    is it remotely possible that another complex lifeform is based on another element other than carbon?

    I am intrigued by the possibility there could be 'alien robots' somewhere in the universe so advanced as to reproduce themselves and perhaps 'existing' long after their creators had become extinct.

    But as to whether any other form could have started up 'on it's own' you'd probably need to ask that in the Biology section.

    If anything I think we'll find out that we once rose to greatness and messed it all up and landed on this planet. We are just trying to regain that greatness so we can screw it up again. Someplace out there might be who we once were shaking their heads saying....your doing it again you morons.

    Life on a planet orbiting the opposite side of the sun wouldn't be closer than we think. I still think it's possible for Mars to have present day life, deep down in some nice geothermal niche. Mars gets closer than the 300 million kilometers of your hypothetical planet 8)

    I agree. Somewhere near the ice caps, where liquite water could be found underneath the surface.

    Yep all those little microbes on Mars and Venus - I can see them all nodding in agreement, First Mars, Then Venus, Now Earth.

    I understand people wanting to believe that life may exist in our solar system on other bodies as well as earth, but I think it is a shame that space agencies continue to pump money into probes which look for evidence of life. This is a waste and could be used for much more productive scientific planetary experiments.

    The whole logic seems to be that certain regions (martian poles, europan 'seas') have a superficial resemblance of habitats on earth (antartica, ocean floors). Since life exists in these habitats on earth it could exist on mars/europa too. I think the questions we should be asking is could life ARISE in these habits, not whether it could SURVIVE in them.

    These are extreme habitats populated by very highly adapted extremophile organisms. Life on earth has gradually adapted to colonise these extreme conditions, I doubt whether these conditions alone are conducive to the spontaneous origination of life.

    IF (big if) there is anything alive on mars it would most likely to be bacteria from earth that got their through debris from a meteorite impact (or hitched a ride on one of our probes!).

    Compared to what Earth was like when life was formed; inside Mars is a pretty good looking place. When life formed on Earth the planet was nothing like the haven for life like it is today. But I do agree we waste too much money on this obsession we have with microbes being on another planet. Many projects go unfunded that could use this money. We are quickly getting into politcs and biology though and both are things I try to avoid.
