Cosmic Questions of Alien Mice and Men

One of the joys I had growing up in Georgetown, South Carolina that extended well into the 1980’s was the ability to go outside and see the stars of the Milky Way scattered across the sky at night. Of course these very impromptu observations were before both urban sprawl forced a huge jump in nighttime illumination for safety reasons and damn suburbanites developed the narcissistic need to show off their carefully tended lawns with landscape lighting. Such is the nature of childhood I guess that something so simple and pure can literally be lost in the glare of what some call progress. Truthfully, I cannot blame progress all that much, while my hometown was a very pleasant place to live it would have only been a matter of time before one of the newer neighbors called the sheriff on my ass accusing me of being a peeping tom.

It would be a supreme understatement of criminal proportions to say those quiet nights watching the stars were awe inspiring. In truth I actually felt privileged to be able to see the majesty of creation wheel before me. Couple that with Carl Sagan’s show “Cosmos” that aired about the same time and there were times I could stand outside looking at the stars and almost hear his words describing the birth of the universe.

One of the problems of being overly curious is that you cannot stand outside looking at night sky for any length of time and being to wonder if their might be sentient creatures like us living on alien planets circling those distant stars. The next natural step, fueled by science fiction both good and bad, is wonder if maybe these other intelligent species might be advanced enough to travel the almost unimaginable distance and come visit our small but hospitable world.

Saying that such journeys would be difficult is a monumental understatement and to be fair there are a number of respected scientists that say manned interstellar travel is simply impossible given the energy requirements needed to accelerate even a relatively small mass object close to the speed of light. For them any possible interstellar community would be restricted to a galactic internet with various species broadcasting radio messages to each other, then waiting the centuries, if not millenniums, for a reply.

Of course this stay-at-home attitude ignores such possible propulsion technologies as nuclear pulse, fusion engines, antimatter drive, and the really wild ideas for surfing space-time itself which, some say, would allow us to break Einstein’s law about not traveling faster than light. Except for nuclear pulse, which was actually tested on a very small scale in the 1960’s, all of those possibilities are for the foreseeable future just theoretical curiosities. Yeah, it bugs the living shit out of me.

Not surprisingly there is intense debate among the stay-at-home crowd and those like me who would jump at the chance to “explore strange new worlds.” The former likes to bring up Fermi’s Paradox which says that given the high probability that there are at least a few other intelligent species in the galaxy if interstellar travel was possible even a relatively slow starship, say going just ten percent the speed of light, should have visited already. In other words, even at an interstellar snail’s pace it is possible for an adventurous species to explore the entire galaxy in just a few million years. Yes, the rocket scientist boys and girls have checked the numbers on that one.  

The obnoxious stay-at-homes also like to point out that Earth was prime carbon-based lifeform real estate for billions of years and should have been snapped up by at least one colonizing species. Furthermore, given that complex life has existed on this planet for millions of years if any alien Jim Kirks had stopped by they should have left examples of their visit in case intelligent life ever evolved. Now the stay-at-home get vague here, and never really state what type of evidence any possible aliens might leave. Just off the top of my head some of the junk they might have left behind could be a few burned out warp drives, mounds of alien trash including poo, and just maybe the occasional crewmember left marooned on an airless moon because it would not stop farting on the bridge.

Frankly I am in the Star Trek camp who believes all the stay-at-home are unimaginative poopoo heads. Interstellar propulsion technology is not even in its infancy and while it will obviously be too expensive for nation-states to pursue alone there is simply just too much promise to abandoned research when the human race could end up with the chance to explore the galaxy. Unfortunately, even if we get the chance to “seek out new civilizations” the basic principles of evolution preclude the possibility of someone playing James T. Kirk and bagging some smoking hot green-skinned Orion babe. Yeah, you can probably begin to imagine what my childhood was like but don’t go there.

Now there is sort of a bridge between the Star Trek types like me and the aforementioned unimaginative poopoo heads. The idea is that even if manned interstellar travel is impractical bordering on impossible an adventurous species could send self-replicating probes on the long and very slow journey. Once these robotic emissaries arrive at a promising star they radio back what it has found and then go about building copies of itself which in turn begin the journey all over again.

From Phy.org, posted July 19, 2013:

The robotic probes could explore our galaxy and self-replicate themselves from interstellar dust and gas, after which the parent and child probes would each set off for a different star, where they would look for signs of life and then self-replicate themselves again. The probes would therefore disperse themselves radially across space.

In all the scenarios the scientists looked at, exploration timescales were reduced when the probes were self-replicating, and they concluded that a fleet of self-replicating probes could travel at only 10% of the speed of light and still explore the entire Galaxy in the relatively short time of 10 million years. This is a tiny fraction of the age of the Earth and the scientists say the results reinforce the idea of the "Fermi Paradox."

The Fermi Paradox, proposed in 1953 by physicist Enrico Fermi, suggests there is a contradiction between the high probability that civilizations exist elsewhere in the Universe and the fact that there has been no contact between ourselves and other civilizations.

Dr Forgan said that the fact that we have not detected or seen any evidence of alien probes in the solar system suggests there have been no probe-building civilizations in the Milky Way in the last few million years or that the probes are so hi-tech we are unable to detect them. Another possibility is that probes could be programmed to make contact only with civilizations that pass a set measure of intelligence, which could be the ability to detect the probes.

Now even this compromise opens up its own can of alien face hugging worms. If alien robotic probes are hanging around our solar system wanting to make contact with us hairless primates what are they waiting for? The disturbing idea I cannot shake is that they do not consider us an intelligent species, and who in this great big wide cosmos would blame them? Even hamsters know not to make a mess of where they live and do not get me started on humanity’s other sins.

Secondly, it only takes one Nazi-like alien species suffering from paranoid delusions to send out fleets of self-replicating destroyers whose only purpose is to listen for other intelligent lifeforms leaking out television broadcasts of their versions of The Tonight Show or I Love Lucy then drop by their home planet and nuke the living daylights out of them. Think I am crazy? First, my mother had me tested and second even Stephen Hawking has said pursuing alien contact might be a very bad idea.

In my opinion humanity making first contact with another intelligent species might be the best thing that ever happened to us. It might just be what is needed to make the bulk of our species realize there is more to existence than just our civilization’s perpetual idiotic games of empire building, destroying the environment for a buck, and some nation making an attempt at global domination.

The incident that sticks in my mind though happened to me on was on one of those star gazing nights back in my hometown. It was during one summer night after a particularly bad thunderstorm had knocked out power to the neighborhood. The storm cleared out quickly leaving my backyard almost pitch black and the stars an unimpeded stage. Looking through my granddad’s old army binoculars I had gone into serious geek mode after catching the sight of Jupiter and at least three of its Galilean moons.

My reverie was destroyed when out of nowhere I heard someone shout, “What the Hell are you doing boy?”  Out of the darkness emerged a man I called “Uncle Boo”, he had heard someone talking to themselves and came over to see what sort of fool was outside after a thunderstorm. Uncle Boo literally scared the Hell out of me, it was like he came out of nowhere. Once I explained he went back home and got his own telescope and we spent about an hour looking up at clear night sky before the lights came back on. While these days nighttime illumination prevents me from seeing the stars like I use to but I still look up and like Enrico Fermi, who was one of the smartest men of the twentieth century, wonder where in the Hell everyone is, or if  they are lurking somewhere out in the darkness watching us, or if maybe they are all hiding from something. 

This is for those damn Stay-at-Home shitheads.
