"The Drake Equation"  What are the chances of life on other planets?

"The Drake Equation" What are the chances of life on other planets?

By Ian Brockwell


The Drake Equation was an attempt to estimate the number of detectable extraterrestrial civilizations in the Milky Way and was created by Frank Drake more than 50 years ago.


Whilst the Drake Equation takes into account a number of factors, including the theory that technological civilizations tend to disappear rather quickly ", there can be no doubt that the logical conclusion is that life on other planets does exist.


Our search for alien life has concentrated mainly on finding beings that survive in similar conditions to our own and listening for sounds that we can recognize as intelligent.


I am sure there are many life forms in our Universe that not only breathe oxygen as we do, but resemble us as well (two arms, two legs, two eyes etc.). However, you can be just as certain that there are equally as many that do not.


Alien life is likely to come in all shapes and sizes, and intelligence. We should not be surprised at the abilities they may possess, with telepathic powers being high on the list.


Unfortunately, many scientists find it difficult to speculate on what technology might be available to alien life forms and tend to judge all situations based on known science. I find that attitude rather arrogant, seeing as our knowledge of the Universe is almost non-existent. Can we really be sure that time travel is impossible, or even that we can travel faster than the speed of light?


To believe that we (humans) are the only life form in the Universe is just too ridiculous to contemplate, especially when we consider that we share this vast space with many billions of other planets.


For those of us who believe in life on other planets (as I do), we need to ask whether they have already visited our planet, are they still here, and if not, when (not if) will they reveal themselves to us?


People often make fun of the UFO and Alien sightings that are reported, especially as these quite often appear in unusual places. However, we have to remember that if aliens have managed to visit our planet, they would have needed some very sophisticated craft in which to make that journey (because of the distance). This automatically makes them more advanced than we are and perhaps they have no interest in communicating?


This example could be used on our own planet, which we share with many other creatures. How many times have we tried making contact with ants, flies, worms etc?


With more and more Earth-like planets being discovered almost every day, the odds of finding alien life continues to improve, but with our limited technology, it seems likely that we will have to wait for them to come to us first.
