Alien Ham

Exoplanets are trending currently. Why? Recently NASA discovered an exoplanet orbiting a star in the Proxima Centauri system. This planet orbits within the “habitable zone”, and is named (by us) as Proxima B. However, because of its rapid rotation around its star, roughly twelve days to complete an orbit, and the fact that while it is withing the “habitable zone”, it is believed to receive 400 times the X-ray energy from its “sun” than we receive from ours. To that end, it is likely that it is comparable to either Mercury or Venus, both of which are barren and devoid of life.

Why do I bring this up? Humanity has been looking for extraterrestrial life for decades. One would think that it is only a matter of time until we find something, right? Maybe not.

2016 marked the 100th anniversary of the W7DK/W7OS Radio Club of Tacoma. This is the single oldest, continuous, ARRL affiliated radio club in the whole of the United States. This is a big deal when you consider that  on 23 December 1900, Reginald A. Fessenden became the first person to send an audio single via wireless transmission , and that  he made the first commercial broadcast on Christmas Eve of 1906. This means that radio has been a known medium of communications for 116 years, and that there are some earlier experiments that predate these two events.

What does this have to do with aliens? Plenty, if you don’t mind some pretty extreme mathematics. It really has to do with how far radio waves really carry, and they really do carry quite some distance.

I’m going to go ahead and be generous. That is to say that I’m going to ignore the first 16 years of radio transmissions, at least for the moment. Those first sixteen years really are important, but I want to make things easy, at least to start with.

A radio wave travels at the speed of light, which is roughly 186,200 miles per second. This works out to 11,172,000 miles per minute. That, in turn, works out to 670,320,000 miles per hour. In the course of twenty four hours, a radio signal will travel 16,087,680,000 miles. This is nearly four times the distance between the Earth and Pluto. In a month, that signal will have traveled over 482,630,400,000 miles. That means a radio signal will travel, in one year, a distance of 5,876,025,120,000 miles. In a century, that distance is clearly seen as being 500,876,025,120,000 miles. This doesn’t account for those first sixteen years, which adds another 94,016,401,920,000 miles to the overall total.

All that looks impressive, but meaningless, until you start to look at a list of all the potential exoplanets that are thought to exist in the habitable zone. About a quarter of those planets are less than fifty light years from Earth, and some are even closer than that. To date, we have not received an authenticated signal back from any of these supposedly closer exoplanets. Let that sink in for a second.

Over the years, we’ve seen numerous UFO sightings, some going back as far as 1697, though the first fully credited sighting was in 1947 near Mount Rainier, in Washington state. Yet, despite these supposed sightings, we have no hard evidence that extraterrestrials exist, aside from various conspiracy theorist drivel, much of which is easily debunked. Even the “WOW signal” from 1977 has now been attributed to a passing comet, a theory that may very well be tested soon, which only further depletes the potential pool of evidence for extraterrestrial life, and only leaves the flimsiest of evidence, and that being the previously mentioned stuff that is easily debunked.

What does this mean? Ultimately, it means that in all of decades of searching for extraterrestrials, we have found nothing. Furthermore, with at least six exoplanets existing within 56 light years of earth, if they had a level of technological development equal or greater than that of our own (most people seem to seek extraterrestrials with a greater level of technological development for some reason), then we should have already heard something from them, something that would have already put our world into technological overdrive, as we rapidly built a deployed our first hyper-light drive systems. However, no such signal has been shown to exist, and most claimed signals have either been debunked, or have been relegated to suspected pranks by unscrupulous individuals with questionable motives.

Radio has been around for over a century. If there were an extraterrestrial race with a level of technology equal to or greater than our own, we would likely have heard back from them, and it would have been impossible for any government to block such a communication. I know some will believe that I am wrong, and I accept that, but I am firmly convinced that radio, and the lack of an authentic signal from an extraterrestrial race that off of the Earth has heard, is sufficient evidence to suggest we are alone in the universe. This is observational science, and radio is all about what we can observe. If I can be proven wrong, by a personal radio greeting by an extraterrestrial, and they can prove it, I will admit to it, before committing suicide.
