Re: Happy U.F.O. Day!
That's what I love about these threads Mups, as Gumbud said somewhere else when talking about astrophysicists, "Your guess is as good as theirs" That I firmly believe, only difference is they're paid $100,000 dollars a year for their guesses, (I checked). When it comes to the great beyond we know precious little and it's open season all the time to say what you think, I love reading what other ordinary folks think about the whole thing, and nobody can prove you right or wrong no matter how outlandish your theories seem.Re: Happy U.F.O. Day!
I'm yet to be convinced of the existence of UFOs as such, but I am absolutely convinced as to the existence of life on other planets, especially now that we have direct observational evidence of extrasolar planets and it seems that they are far more common than previously thought.Re: Happy U.F.O.

Thanks Jem, this is a pet subject of mine.Re: Happy U.F.O. Day!
It's not only the distances involved - time-spans also feature, because compared to the total life-span of the Earth, humans have only existed for a fraction of a second, and the necessary knowledge we have gained is an even smaller time-fraction. After all, the dinosaurs lived longer than we have so far. The chances of another equal civilization close enough to travel here being at the same stage of development at the same time is remote to say the least. Life - yes - but not as we know it Jim...Re: Happy U.F.O. Day!
It has been suggested that to find possible civilisations 'out there' then we're looking for the wrong things. Assume a civilisation lasts long enough to outgrow the energy supply capabilities of a single planet and assume it cannot escape its own solar system, then population and resource pressure would drive it to utilise the total power output of its own star. This could be achieved by a sufficiently advanced civilisation building some sort of Dyson construct to capture and utilise all the energy of the star. I'm not suggesting the so-called 'Dyson Sphere', a shell around the star, as this would be orbitally unstable, but maybe a series of orbiting smaller, though still vast, discs.
