The Myths Surrounding Alien Life Forms
Bookmaker Paddy Power is offering odds of 16-1 that the existence of extraterrestrial life will be confirmed this year.
- Maggie Aderin-Pocock, There IS life out there: Space scientist says there could be four intelligent alien civilisations in our galaxy, Mirror News, 2 July 2012
Note the dates: "confirmed this year" and "July 2012". Apparently bookmakers know little more about extraterrestrial (aka alien) life as the scientists who study the cosmos looking for it. That's not much.
Let's put a little perspective into this. Scientists who believe they know about such things as life on earth claim that the chances of life happening on a chunk of rock at just the right distance from a relatively small and remote star as our sun would be about the same as you or I winning a big lottery each and every day in the coming year.
They would be primarily biologists and others who have studied the intricacies of life on earth and its relationship with the respective environments of each. The odds against us being the way we are seem staggering.
Over on the physics side of science we have those who look at where earth is relative to the rest of the Milky Way galaxy and the universe and say there must be countless planets similar to ours. They conclude that the components that are necessary to generate living things (call them chemicals) exist in abundance in the universe, so there must be thousands, even millions, of planets like ours with life already growing and evolving.
With odds like those, it's no wonder bookies can offer grand looking odds to those who believe they have a decent chance of winning a big lottery.
Scientists claim that it's likely that life on another planet somewhere must be more evolved than we are, thus they have figured out how to travel astronomical distances (literally) in a relatively short period of time. They never explain why this could have happened faster elsewhere than it did on earth. Nor how the aliens could have found us amongst billions off possible locations.
Light from the nearest star system to earth takes over four years to reach earth. Scientists have not even imagined a way to travel faster than a tiny fraction of the speed of light. Indeed, most still believe Einstein's claim that nothing can travel faster than the speed of light. Even at the speed of light, the stressors on life forms inside a vessel would likely be greater than their bodies could withstand.
Meanwhile science fiction writers have so influenced real scientists that the latter now believe that alien life forms coming to earth will want to destroy it, or at least turn humans into slaves. They never explain how a few alien life forms would manage to conquer and overcome an entire planet. Or why, as they would not come in massive numbers as they would only be explorers and adventurers anyway.
We know that distances between earth and other planets that could be somewhat like earth are so great that it would require propulsion systems far advanced of anything science could conceive of today in order to make such a trip in fewer than several successive lifetimes.
Think about that for a moment. Would you send your astronaut son or daughter into space knowing they would (could) never return and that their children and grandchildren and even generations beyond that would be born and live their entire lifetimes on a vessel moving through uncharted space? Never to set foot on land. That doesn't make sense.
If one of our space vessels made it, over several generations of humans, to a distant planet that could sustain life, what are the chances that the vessel could turn around and make the trip back to earth without a problem that would destroy it? Remember, two of those very dependable American shuttlecraft were destroyed right here on our own planet.
Protection against space debris, wandering space litter such as rogue asteroids and radiation science has not even discovered yet--to say nothing of living in cramped quarters for decades at a time, with resulting muscle atrophy--would present problems beyond what science today can address with confidence.
Other small questions should enter the picture. We know that unmanned space vessels are the way to go when exploring beyond our own atmosphere, so why would an alien vessel travel with a complete crew (including earth-shattering weaponry) for generations, only to return home generations later to say "Hey, we found one!"?
If we were to send out an exploration vessel today, which direction should we go? Science has no evidence from decades of watching and listening to space that suggests there could be life anywhere else in the universe. A "shot in the dark" would have a much greater possibility for success than a probe with no known or prescribed destination.
We have sent out messages into space and listened for incoming messages for decades, but heard nothing. The SETI (Search for Extra-Terrestrial Intelligence) had to be shut down after decades of searching for lack of evidence of any kind.
This is not to say that there is no life out there, be it microscopic or even more advanced that we are on earth. It is to say that the effort may not be worth the cost, at least at this point.
In other words, finding a distant planet to which we could send a sampling of life from earth, in order to preserve what we have today, will not likely be feasible in the foreseeable future. Maybe never, as the universe itself is expanding at a horrendous rate, making everything in it farther apart.
We had better get busy cleaning up our own backyard before we have nothing left to send out into space in order to preserve life as we know it.
We allow some 300,000 chemicals to be poured into our waterways from factories and half a million chemicals to be whooshed into the air from smokestacks. We know very little about what effects they have on life right here on our planet. Yet our governments and our industries want us to worry about the temperature of our atmosphere warming by half a degree.
Of course industries want us to be concerned over global warming, it will take our attention away from the countless chemicals they put into our food, our medicines and our vaccines (dozens of which are now given to very young children, by law, with no evidence of their effectiveness or their long term effects on health, but an increasing body of evidence telling us they do more harm than good).
If you were an intelligent species that had travelled for hundreds of years through space, would you want to adopt homo sapiens as slaves?
