I just read an article about the nature of movies in regards to the special qualities of Earth that seem to attract so many invaders. It’s a bit tongue-in-cheek but there are some valid points. Why would an advanced alien civilization visit Earth?
The question I’m going to think about today is along the same line although from the opposite position. Why wouldn’t advanced aliens visit the Earth? Because that’s the real question if you believe the galaxy is teeming with technologically advanced civilizations. I’m one that finds it difficult to believe that such civilizations do not exist. The universe appears to be some 14 billion years old and current estimates have our galaxy clocking in at 13.6 billion years. There are some 200 billion stars in our galaxy and possibly a lot more. Recent evidence suggests that most stars form planets, that water is abundant in the universe., the buildings blocks of life are everywhere, and places where life might thrive seem common.
And yet, silence.
One common explanation is simply the massive distances involved. If the speed of light is the maximum then getting to our little world is no easy trick even for a race that’s been around millions of years. I find that explanation very appealing.
One of the main factor’s driving human exploration of space is simple curiosity. We want to know what’s out there and we particularly want to know if we are alone. What if the answer was an unequivocal no. What if there is microbial life on Mars, a thriving underwater community on Europa. What if life is, as I suspect, everywhere. What if almost every star system eventually allows for intelligent life? What if you know all about it? What if you are communications with tens of thousands of other species? Does this dim your curiosity? What interest is there in a young species just reaching out to the stars?
What if finding such a new species was common-place? What sort of regulations would you put in place around such a community. We certainly understand the idea of the Prime Directive of the Star Trek world. Don’t influence young races, don’t contaminate them. It’s a reasonable explanation.
Perhaps life is so abundant that such advanced races just don’t care until we get to a certain level of technology. We just have nothing to offer them.
I’m sure there are other explanations and any of them might or might not be true. There is just no way of knowing. The reality is that we have yet to have any credible contact with a species from another planet. Perhaps we are alone. Perhaps the aliens walk among us, studying or plotting. Perhaps they are out there keeping their hands off for the moment because of their own rules of conduct. Perhaps the distances are just too daunting.
Maybe someday we’ll learn the answers to these questions and that’s a good thing. We’re here, we’re striving to find more, to learn more, to explore our world, to understand the universe. What more is there to do?
I guess that’s my point. Don’t be daunted by the lack of information. Keep looking for more. Follow the facts, don’t be fooled by those theories you want to be true. It’s fun to speculate, to guess, but when it comes to reality, stick to the facts. I’d love the universe to be teeming with intelligent life but the evidence of such does not exist. Therefore I cannot argue that it does.
