    Are we alone in this Universe or is there other life? Have we been visted by Extraterrestrial life here on Earth?

    I personally think we are not alone in this Universe and there is Extraterrestrial life out there. [​IMG]

    Interesting thread Razor.

    I am a firm beliver that we are not alone in the universe. When you conmsider the truly infinate area that is the universe, then surly we can not be the only planet that has developed life.
    Now whether or not that life has come to visit is hard to say. There is plenty of eye witness accounts of UFOs and abductions , but no reall hard facts that prove beyond doubt. I have never seen a UFO, or any aliens, But would like to think that not every reported case is fake or just some ramblings of the local nutter :D

    Keep watching the skys! :eek:

    I believe it is impossible that there is not some form of life in other parts of the universe.
    I do not, however, believe that we are visited by extraterrestial beings or space ships.

    With an almost infinite number of suns and planets out there, there just has to be life somewhere else.

    Bear in mind, too, that we need not consider only life forms in PHYSICAL matter. What if life has developed elsewhere in the Cosmos which takes a form that doesn't require physical matter as its prime mode of manifestation?

    Hmmm ... bit deep and metaphysical for a Sunday morning. Good stuff!

    If an asteroid created the right conditions for mammal based inteligent life on Earth then maybe most other inteligent life is reptilian or fish based; not mammal.

    What if we were visited by inteligent reptiles with a freezer full, or worse still nearly empty, of ready cooked apes?

    Good point. What I suppose I meant was there was probably infinite,since no-one will ever know.

    It was early (for me) and I'd not long got out of bed - well, that's my excuse.

    I do desperately want to believe in it but... My heart tells me that with all the trillion's and gajillion's and farillions (definately made the last one up!) of planets and solar systems out there there must be life somewhere else!

    However apparantly the mathamatical odd's on it happening when and how it did on this planet are so.. Astronomical (pun intended) that it is almost garunteed that it wouldn't happen anywhere else!

    I think its highly unlikely given the size of the universe that we'll ever come into contact with other intelligent life in any meaningful way.

    We might pick up the odd transmission but its unlikely to be two way given the time periods involved in sending a reply.

    I don believe we'll ever break the light barrier. We might make ourselves effectively immortal in some fashion , either physically or electronically and this might offset some of the huge time periods required to travel any significant distance... but why would you want to?

    Of course we might create our own intelligent life , who's to say an AI or virtual worlds are not as valid as the physical one.

    Given that we haven't made progress in the 3 decades since the moon landings (that some say never happened anyway), we're in for a wait just to get to Mars

    If an asteroid turned up anytime soon we're screwed

    New thread for believing in an afterlife and view earth events?

    I heard that for every grain of sand on this planet there are a billion stars so imagine how many planets there must be INSANE there has to be life somewhere

    I believe in extra terrestrial life as in life on other planets but i don't think we ever visited the moon ( i remember the Bond flick Diamonds are Forever made fun of the moon landings and a great little flick called Capricorn One also got made )

    We treat animals as meat products to be eaten when and as we choose so it would be interesting if a superior lifeform came along that didnt understand our language and considered us to be highly inferior and simply meat products and maybe they would ship us to the meat processing plant or use us as recreational fun, we like to think of ourselves as a higher lifeform but we might just end up being part of the food chain.

    ^ aliens would have the technology or capacity to travel millions of light years to earth, but wouldn't be able to decipher our language?

    All hypothetical of course :D

    They come billions of light years and then find they have more in common with chickens so after conversing with the chickens for a few hours they decide to free them all and destroy mankind.

    Not that old chestnut.

    This was posted a while back for all you doubting Thomases out there ;)

    http://www.redzero.demon.co.uk/moonhoax/

    Personally I think there has to be life out there, but that we are too far away to have been found by anybody else. From what I remember, earth is basically in a backwater of the galaxy.

    Plus, given the age of the Universe it is entirely possible that millions of civilisation have been born and then died off before we even became amoebas on this planet. The dinosaurs were around for a good few million years, so we are still at first base as a species - and we could be wiped out in the next few centuries (war, disease, famine, climate change, whatever), never mind surviving for millions of years into the future.

    SETI: The Drake Equation

    --------------------------------------------------------------------------------
    [ Description || Try the Drake Equation for Yourself ]
    --------------------------------------------------------------------------------

    Description
    The Drake Equation was developed by Frank Drake in 1961 as a way to focus on the factors which determine how many intelligent, communicating civilizations there are in our galaxy. The Drake Equation is:

    N = N* fp ne fl fi fc fL
    The equation can really be looked at as a number of questions:

    N* represents the number of stars in the Milky Way Galaxy
    Question: How many stars are in the Milky Way Galaxy?
    Answer: Current estimates are 100 billion.
    fp is the fraction of stars that have planets around them
    Question: What percentage of stars have planetary systems?
    Answer: Current estimates range from 20% to 50%.
    ne is the number of planets per star that are capable of sustaining life
    Question: For each star that does have a planetary system, how many planets are capable of sustaining life?
    Answer: Current estimates range from 1 to 5.
    fl is the fraction of planets in ne where life evolves
    Question: On what percentage of the planets that are capable of sustaining life does life actually evolve?
    Answer: Current estimates range from 100% (where life can evolve it will) down to close to 0%.
    fi is the fraction of fl where intelligent life evolves
    Question: On the planets where life does evolve, what percentage evolves intelligent life?
    Answer: Estimates range from 100% (intelligence is such a survival advantage that it will certainly evolve) down to near 0%.
    fc is the fraction of fi that communicate
    Question: What percentage of intelligent races have the means and the desire to communicate?
    Answer: 10% to 20%
    fL is fraction of the planet's life during which the communicating civilizations live
    Question: For each civilization that does communicate, for what fraction of the planet's life does the civilization survive?
    Answer: This is the toughest of the questions. If we take Earth as an example, the expected lifetime of our Sun and the Earth is roughly 10 billion years. So far we've been communicating with radio waves for less than 100 years. How long will our civilization survive? Will we destroy ourselves in a few years like some predict or will we overcome our problems and survive for millennia? If we were destroyed tomorrow the answer to this question would be 1/100,000,000th. If we survive for 10,000 years the answer will be 1/1,000,000th.
    When all of these variables are multiplied together when come up with:
    N, the number of communicating civilizations in the galaxy.


    --------------------------------------------------------------------------------


    The real value of the Drake Equation is not in the answer itself, but the questions that are prompted when attempting to come up with an answer. Obviously there is a tremendous amount of guess work involved when filling in the variables. As we learn more from astronomy, biology, and other sciences, we'll be able to better estimate the answers to the above questions. Many of these questions will be addressed in depth in future issues of Enigma.



    --------------------------------------------------------------------------------
    chew on that one for a while :)

    The truth is out there scully

    I have always believed that we cannot be the only life forms that have evolved, when you consider how many stars are in existance, and how many must have planets. There have to be a fair few that have conditions which are condusive to some form of of life. Not all life forms would necessarily be in a form which we would perceive as life, but nevertheless are.

    Given the distances which need to be travelled for us, or them, to be visiting I can't however, see us having cosy chats over the garden fence, at least not for a long time yet.

    There are many theorised ways of crossing the vastnes of space. FTL Drives, Wormholes, Warping space/time, cryogenics.

    Its not impossible to go somehwere, the problem is, WHERE do we go?

    We need to find a destination first. Somwhere that can be colonised. Then we send folk there on a one way trip.

    In order to find our destination we need to focus on developing better telescopes.

    As to wether life exists, Me thinks it does since there are so many darn planets out there. We only need to find one planet in a similar situation as our Earth, then the chances of life become huge.

    The other question, Does inteligent life exists? Maybe. But why would they waste their time coming here for? Unles they wanted something from us, and thats probably a bad thing.

    The human race still has a long way to go before we become reasonable enough to deal with.

    Imagine how people would react right now if aliens were to come to earth. Probably panic followed by violence.
    Thats how animals react.

    Monty Python put it quite well:

    Whenever life get you down, Mrs. Brown,
    And things seem hard or tough.
    And people are stupid, obnoxious or daft,
    And you feel that you've had quite enu-hu-hu-huuuuff!
    Just - re-member that you're standing on a planet that's evolving
    and revolving at 900 miles an hour,
    It's orbiting at 19 miles a second, so it's reckoned,
    the sun that is the source of all our power.
    The Sun and you and me, and all the stars that we can see,
    are moving at a million miles a day,
    In the outer spiral arm, at 40,000 miles an hour,
    of the Galaxy we call the Milky Way.
    Our Galaxy itself contains 100 billion stars,
    it's 100,000 light-years side-to-side,
    It bulges in the middle, 16,000 light-years thick,
    but out by us it's just 3000 light-years wide.
    We're 30,000 light-years from galactic central point,
    we go round every 200 million years,
    And our galaxy is only one of millions of billions
    in this amazing and expanding universe.
    The universe itself keeps on expanding and expanding,
    in all of the directions it can whizz,
    As fast as it can go, at the speed of light you know,
    twelve million miles a minute, and that's the fastest speed there is.
    So remember, when you're feeling very small and insecure,
    how amazingly unlikely is your birth,
    And pray that there's intelligent life somewhere up in space,
    because there's bugger all down here on Earth.
