Guess I'm lucky being a lifelong New Yorker - I can get all that in Times Square, just a ferry/subway ride away...

The problem with the Fermi paradox is that intelligent life that proceeds to control electromagnetism (and thus radio, etc.) is much more rare than simple extraterrestrial life. Earth had "intelligent life" for maybe a billion years (animals), but humans only got into radio in the last few hundred years. That's, like, nothing! Other animal species lived for millions of years and obviously never got into what humans have gotten into. And of course, evolution is pretty haphazard. What if a giant asteroid (comet?) had never wiped out the dinosaurs? Nothing says any other planet has to evolve like ours did. In fact, you can be sure they won't. Then there's the issue of the lightyear. It's just so darn far! And we're talking about hundreds, thousands, hundreds of thousands of lightyears just in our single galaxy. If you want to start invoking the statistical possibilities of the billions of other galaxies, you're talking about distances that are pretty well beyond imagination. I think the most we can hope for is a signal from out there, which has been traveling at light speed. But signal strength drops off with the square of the distance. It would have to be really strong at its emission, and our detectors would have to be super sensitive. We're getting fairly good with the latter, but.....

I have avoided this thread because a) I don’t know squat about astronomy; b) I am pretty much unread on all things space related (tho’ I do love Apollo 13); and c) thinking about this stuff makes my brain hurt.
Having said all that, I think any Earthling would be pretty arrogant to think we are ‘it’. The Milky Way a 100,000 light years across and we’re the only intelligent life? Good lord….we may be the least intelligent life!

Interesting thread. I'm not sure if it's my advancing age but the optimism of my youth has rapidly accelerated into the pessimism of age and I'm convinced that the human race is too flawed to ever be able to work together in harmony long enough to do much other than fling a few unmanned vehicles into space to see what's out there. I'm quite sure that if any of them encounter anything of note, we'll be long gone.
Our ability to advance our technology has fast outpaced our ability to advance socially and intellectually leading to what one can only conclude will be our self-destruction. Civilizations ascend and decline. This one is in decline and will self-destruct very soon resetting the human clock once again. Now, if you'll excuse me, I'm going to head over to the classifieds to buy a really cool guitar before it's too late! |

Very interesting discussion…
Not being familiar with the Drake Equation, I did a google search, and found this on Wikipedia… Quote:

So....What do you make of UFO sightings. I always felt that if ET life were to visit Earth it would not take a form that mimics our understanding of life, e.g. riding in vehicles with propulsion, shapes within our geometric understanding, and lights. But yet the sightings are pretty cool and mysterious. How does all this fit into the paradox...?

I graduated high school 54 years ago. If our valedectorian had correctly predicted that some of us would be sitting in front of a typewriter attached to a television, which was then hooked up to a worldwide audio/video/media network, bidding against others located worldwide in a live auction for the privelege of paying $100 for an electric toothbrush, she'd have been laughed off the podium. It wasn't just the problem that the technology didn't exist, it was that the idea of the technology only existed in fiction. Our kids know their parents' science fiction as existing facts. Let's hope the kids in later generations can do the same. "a substantial ex ante probability of there being no other intelligent life in our observable universe".[83] The key word here is "observable". Our current capability to "observe" is about level 1 out of 1,000, which makes the above conclusion valid, but also insignificant. This is a fun forum |

Traveling in time is harder for me to comprehend than traveling far. What is the scientific probability for time travel - beyond Rod Taylor and Yvette Mimieux....

Technology may enable us to get going really fast through space, but there's a lot of gas and dust and other debris out there, so shielding is going to be a major problem for any spacecraft. Technology may also solve that problem, but then there's the ridiculous distances involved....
