Alien Life

Ragnarok · #1 August 11th, 2002, 08:45 PM

I voted for "Other" because I don't believe there are aliens out there. I also don't believe in other demintions either. I mean if you think about it earth is a rare planet indeed. It's the only one that can sustain life. If the earth was moved just a fraction of an inch closer to the sun, we'd burn up in under a minute. If we moved a fraction of an inch further way we'd freeze to death in a matter of moments. Scientists have said this themselves. Humans will eventually become space travelers in time, but not for over 100 years. When and IF we develop the technology to colonize planets it'll be tough to do that when you consider the point of the earth being the EXACT right distance from the sun down to the smallest number of measurement. They'd have to build Domes to live in, but even then it'd still be next to impossible. But that's just MHO

"f the earth was moved just a fraction of an inch closer to the sun, we'd burn up in under a minute. If we moved a fraction of an inch further way we'd freeze to death in a matter of moments."

heh. Sorry, but this is wrong. Because if this was true we'd all be dead, the Earth's orbit isn't perfectly cirular. It's about 1.7% off.

"In January when we're closest to the Sun (perihelion), the distance is 147.5 million km. This weekend we will be 152.6 million km away--a five million kilometer difference."

from second article.

Although Capnag comments are essentiually corect, it takes leap of faith to suggest that we or aliieans in same position will enjoy similar progress in future. After all, it is 30 years since we get to the Moon and to my best knowledge, there've been no major progress in human expansion beyound our Homeworld. And somehow I really doubt that it will ever occur - it is just too costly and has no direct financial and political (like reelection in 4 years) benefits. It is entirely possible that we reaching new sort of technological plateu.
I have no doubt about immense future progress in computer scince and biotecnology but it will only keep us ancored to Earth, ever more dump and playing computer games of galactic conquest instead of actually sucrifice excesses of our hedonistic life in order to actually do it !

What aliens? Heck, what humans? The population of the universe is zero! See, space is infinitely big, right? So it has an infinite number of planets. But not all planets have life, so only a finite number of planets have life. A finite number divided by infinity is zero, so therefore zero percent of the planets in the universe have life. Therefore the population of the universe is zero.

Seriously though, I think that any aliens that visit Earth would probably be friendly - any race developed enough to have interstellar travel would probably not be warlike, or they would have destroyed themselves sooner. On the other hand, we're on the verge of achieving spaceflight, and we're pretty warlike...

There is a rather signifcant gap between interstellar flight and spaceflight; especially if FTL travel isn't possible.

I'm not sure I'd like to have advanced aliens landing here even if they are friendly. Consider what has happened to more primative cultures, right here on Earth, when confronted with a more advanced culture. Usually the more primative culture is damaged or destroyed.
American Indian vs European or the Zulus. Borneo cultures or the amazon cultures in more modern times.
SO I say to any alien culture studying us: Go ahead and study us covertly, but leave us alone to develop to at least interstellar capability.
And this a little OT: to those that say we have a wrecked spaceship at Roswell - SO WHAT? Even if true, it would be like a caveman finding a wrecked automobile. What would he do with it? He certianly couldn't fix it or build a new one! The most he could do, perhaps, would to get the principle of the wheel from it. And even that wouldn't be particually useful to a CAVEMAN!

I think that a wheel would help us, though--it's all about the time it takes for development. I remember playing an old Civilization game. It starts out where each turn is decades' worth of time. As you get more sophisticated, more major things are discovered in less time. Essentially, as we get more advanced, so do our tools for analysis. If alien technology is similar enough to our own concepts, we could possibly reverse-engineer it. Of course, whether we can do that without destroying the object in question or ourselves is a whole other debate.

Personally, I don't think we'll achieve Star Trek-like societies for quite a while, if ever. We're too factional as a planet to get our act together and unless we discover the interstellar equivalent of gold, there's no financial gain in it for people. Just look at some of the space programs around the world. Everything from development of future technology to tracking NEOs is afforded a fraction of the funding it would cost for a single military jet. Some bombs we've dropped have cost more than the annual budget of research and development teams. Between that and the fact that close-minded, lazy people breed more than the intelligent/open-minded ones do, and science fiction will most likely remain so.
