The size of the universe, at this time so many billion light years, is of no
relevance to the possibility of life. It will always remain out of reach of mans most powerful telescopes, and must remain empty. Nothing else is possible because if we could see the edge of the universe then we would know everything. This also means there can be no other lifeforms. |

This also means there can be no other lifeforms I believe the complete opposite but sadly neither of us can prove what is out there so no-one is right or wrong. |

it easy 0.00001 to back that life is out there
only 400 years ago we thinks the world was flat and 2 to 3000 years ago we thinks the god is our sun there is life out there where there is water and heat then it beeming with type of lifeforms |

..100o and counting..... Brrrrraaavvvvooooooooooooooooooooooo.......... and hurry up......I would like some proof before I die...thanks |

nice thread, something interesting to find out about
all new to me, will have lots of fun reading all about it thanks for posting |

By:
..and to recap...some mind blowing numbers posted earlier on....
an estimated 17 billion earth size planets in our galaxy (the milky way) alone.... and an estimated 100 billion other galaxies in the universe.....!!!!!!!!!! ..even if only a tiny tiny fraction of earth size planets are in the habitable zones surely there is something else out there!!! ...amazing.... |

Anybody that thinks that we are alone in the Universe - is thick.
|
|
By:
not really, anyone who believes that that there absolutely is other life is thick, because there is absolutely zero proof or evidence. You may as well believe in god.. and who says a planet has to be like earth for life to exist?
We could be all alone, we really could. |

" thick "
your thick if you believe or thick if you don't ! No-one is thick its just you have two contrasting views I believe one to be the case rather than the other does not make me thick imo. Anyway who can disprove that our galaxy is not a speck of dust in someone's fingernail, ridiculous I know but it cannot be proved to be wrong 100% |

It's a matter of probability as we don't actually know
what is the probability that out of the estimated number of habitable planets that none ever saw life develop? the answer is undoubtedly an infinitesimally small probability that life does not exist on other planets however, the gives a finite probability of both outcomes and that means we cannot be sure either way I am definitely in the 'we are not alone camp' but only because of the numbers involved arguing about being 'thick' is really rather irrelevant |
|
By:
Ampleforth (did you go to the school?) it should be obvious from these figures that the chances of there being other life is 1.01 (to use gambling terminology) no sorry, it really isn't obvious, could you show your working please , I really cant get any figure when I try and work it out from those numbers you provided, all it says on my PC after inputting everything is "Insufficuent Data" |

By:
it is not a matter of probability at all....

By:
..hopefully this thread isn't going to descend into name calling....
..been a decent debate with different shades of views on both sides... ..I am obviously on the life is abundant side...but others have equally well put views that disagree... ..and as has been stated.. there is no definitive proof either way....yet!!!! |

...perhaps things will become a little clearer when this bad boy gets fired up.....The James Webb Telescope
...not till 2018 though....  http://www.jwst.nasa.gov/ http://www.astrobio.net/interview/4296/the-james-webb-telescope-will-see-earth-like-worlds  |
|
By:
of course it is a matter of probability, there is no other (reasonable) way to look at it
we have no concrete proof either way (as long as you ignore conspiracy theories about aliens being found on Earth etc) so to determine whether life exists on the exoplanets you can only assign a probability not too bright ampleforth huh? |

..taken from the second link.....
Q: You can see any sort of planets with that? MM: Any planet that’s within 1 AU, like a habitable zone, or [farther] out. John Grunsfeld (JG): James Webb is sold as studying galaxies, but I think its greatest discovery may be a habitable Earth-like exoplanet. That’s what’s going to blow everybody away. Q: So you’d be able to directly image a terrestrial planet, which has never been done before? JG: Exactly. But it wouldn’t be like a Rand McNally map, it would be a spot. But because you’d see a spot, we can then do a spectrum of that spot. MM: You’d actually get a color. If it’s like Earth, it’ll look blue. JG: And, if you had enough time, and there were seasons, with ice covering and then going away, you could study it and be able to tell the difference between winter and summer on the planet, or vegetation, in principle. Just from unresolved single pixels, because of the color changes. ...WOW....not launching till 2018.....  |

The Drake Equation deals with probabilities of Extra Terrestrial Life. We can actually plug some of the numbers in and get an estimate.
http://www.classbrain.com/artmovies/publish/article_50.shtml My own opinion is the Universe is teeming with life but space fairing beings are a lot harder to come by. Life around deep sea vents has actually increased those chances as it means that Sunlight is not needed. For this reason I'm hopeful of life on Europa, a Moon of Jupiter. It has a thick ice crust with an ocean underneath. It's also squeezed by Jupiter and it's other Moons so it has a heat source. The Ice Crust protects the ocean from dangerous radiation from Jupiter and it's strong magnetic field. Callisto (another Jupiter Moon)and Encelydous (a Moon of Saturn) also may have liquid water. I don't think we have to look beyond our own Solar System for life but the numbers are astounding on the number of Suns, Planets and now Moons where we could find life. Just because we haven't found life doesn't mean there is none. Lack of evidence is not evidence of absence. |

do people still take the drake equation seriously?
unbelievable |

does it have a molten iron core that generates a protective magnetic field? does it have water to cool itself? does it have large planetary bodies to soak up stray meteorites. is it the right distance from its sun so that it doesn't get stripped of its atmosphere. does it have soil. has it a moon that governs tides. that is exactly the right distance to give a perfect solar eclipse. what's the odds so far in this accumulator? just like earth - total pisch.

unbelievable Have you got a better equation? You state was is required for human life but if we've only one sample to choose from then how do we know what constitutes life? My money would go on Europa. It was recently discovered that there were jets coming off the Moon. This is great news for any future space mission as we don't have to land there - we can simply fly through the jets to sample it's ocean. The drake equation works well. I think the biggest problem is the life expectancy for any advanced species. We've emitted radio waves for 100 years but I think our own greed and technology will kill ourselves. Whether it's a runaway greenhouse or inventing something like the large hadron collider that will destroy us. Quite possibly a nuclear war could also wipe us out for a good few years. 3D printers can print a gun. What in 100 years when it could print a nuclear weapon? I fear for our own species TBH and would solve the Fermi Paradox of why the aliens aren't here yet. If we find E.T., that could change the way our species behaves but I'm not hopeful. |

Any advance on 17,000,000,000 ? Can anyone say they have a concept of what 17 billion of anything is ? |

heard this from a physics scientist years ago about this age old question.
if the universe is finite (that means its got a limit of existence) then what is outside of the finite zone his answer was is this 'what is north of the north pole' we all know the north pole exists which has a physical existence ie you can put a flag there |
