yes, the drake equation. isn't that the one where they say the possibilities of a planet that can sustain life, then the possibility of it having intelligent life, and so on? I heard that on tv. it was awesome :)Quote:

well as i said before, most of the planets that would have life will most likely be more advanced than us. Think of how long ago we developed radio technology and satalites. About 70 years ago. Now think of how long the universe has been here. I don't know, but it's really really really really really long ago.(no offence to creationism.) So, if the alien civilization was to really exist, they would be much, or at least a little more advanced than us. to think that other planets with life on them would just be single cell or micro organisms would be ludicrous too.Quote:

its not that we don't know, it's that our want to find other civilizations is affecting our judgement. Originally, Dr. Frank Drake(the guy who made the equation) did the equation himself, and got to the answer that there will be 10 civilizations in our whole entire galaxy (which is reeeeally low comapred to how massive our milky way is). But, other scientist and astronomers tried it again, and this time with different numbers. And they got the answer of 1 civilization(which means only us. onoz!!), 5000 civilizations (which is a pretty nice number), and 50 civilizations. I would go with the 50 civilizations. not too big and not too small. the 5000 civilizations would be too much because think of all the galaxies in the universe. Thats just too unrealistic. The one where we are the only one in our galaxy would suck too because the real number is 0.5 or something. Thats a fifty fifty chance in just one galaxy!Quote:

post your opinions, again <(^-^)>
I think we absolutely, positively, without a doubt, definitely need to work on cutting down the number of extraneous adverbs being used in this discussion, don't you think?Quote:

The universe is estimated to be approximately 13.7 billion years old. However, considering the millions or even billions of years it would take for ideal circumstances to allow life somewhere (I think it's suspected that the universe would have been far too unstable to support life for the first few billion years of its existence, not to mention the additional years it would take for suns and planets to form), and then the additional millions or billions of years it would take for life to sufficiently evolve to an intellectual point, we're not really so far off. I believe the oldest known life on Earth was found to exist 3.5 billion years ago, so consider that any other place with intelligent life might need a stable and ideal environment for approximately the same amount of time.Quote:

Star Trek isn't a good comparison, considering that it's entirely fiction. And of course alien races will encounter each other in sci-fi series frequently, else they would be amazingly dull and uneventful. No one wants to watch a TV show that reflects reality: years of monotonous searching for intelligent life with no results.Quote:

And I'm not saying there'd only be two intelligent lifeforms in the entire universe. I'm saying for any two civilizations to come into contact with one another (whether there be 2, 200, or 200,000 in existence), the odds would be less likely than two specks of dust on Earth meeting, given the immense size of the universe.
No, it's because we don't know. If you study the figure, you'll see we'd need to know the exact number of many things we don't know and couldn't find out with current technology. You are correct that personal opinions do effect the outcomes, but at the moment, any figures are entirely speculative and not precise, so opinion (based on what little studies we have now) is all we can really work with.Quote:

And I think the Milky Way is suspected to have somewhere around 200-400 billion stars. Assuming it had 200 billion only, no star was home to more than one advanced civilization, and there were 5000 advanced civilizations, then only 0.000000025% of the galaxy's stars would be home to an advanced civilization (0.0000000125% if 400 billion stars). Those odds aren't really that extreme.
I like how everyone assumes that we are primitive if their are extraterrestrials out there. Who is to say that we are not the most advanced intelligent life there is currently, for all we know earth developed the capability to support life billions of years before any other planet. Also earth is a horrible example of a "life supporting" planet much of what is necessary for creating life is found in extremely minuscule amounts compared to what you think would be here. So for all we know there could be an advanced civilization on a planet that has only been able to support life for 1 billion years because of the fact it had a greater ability to support and nurture it. We can't really use our development as a basis for other life. A more stable planet that was hit by less asteroids and naturally contained the optimum amount of everything needed for creating life and allowing it to evolve and become intelligent then they could have surpassed us in a quarter of the time it took us to get where we are.
Also just for something to chew on, all early on significant growth in human technology is completely unexplainable, we seemed to periodically just jump ahead in our development, also we learned how to smelt gold before we learned who to do things that were much more simple.
