Aliens

Being in everything from videogames to cave walls, aliens are something we as a species seem to be obsessed with. But it is understandable, What sentient creature wouldn't want to know if they where alone in the universe. I think that is one of the over all goals of humanity. But you might think several things.  One that in our huge galaxy (being between 100,000 to 120,000 Light years from side to side) there would be more then one species that can use radio waves.  And if there are species like that why haven't they come to us yet?  Well there are two great theory's that should help clarify this for you.  The first is called THE DRAKE EQUATION. 

(Not you handsome...)

This equation is the scientifically accepted equation for estimating the number of alien civilizations in the galaxy at any one time.  The equation goes like this.

N=R* f_p n_e f_l f_i f_c L

N stands for the number of alien civilizations in the galaxy.

R*stands for the stars formed per year.

 f_p stands for the number of those suns that have planets.

n_e  stands for the number of those planets that could support life per star.

f_l  stands for the number of those planets that go to the next step and actually have life.

 f_i  stands for the number of those planets that's life becomes intelligent.

 f_{c stands for the number of those intelligent species that create a civilization.}

L stands for the length of time it takes for such civilization takes to release detectable signs in to space.

i know this is a lot to take in but bare with me, Once you put in all the numbers, you get  number between 0.000,000,000,000,000,000,080 to 182,000,000.  That is using the lowest acceptable numbers to th  highest numbers.  

Now we come to the second thing i must talk about.  If you look at those numbers then you would have to ask yourself is with numbers like 182 million why haven't we come into contact with aliens?

Well there is a second theory that covers that.

  Its is called the Zoo hypothesis. What this one means is that just like some tribes here on earth modern people are not allowed to go near then.  This way we can make sure that their culture is protected and will develop the way it should.  What i mean is that If there are aliens, they will not show themselves to us until we prove we are done developing.  This would mean that after completing something that proves this we would be welcomed into open hands and integrated into a higher life.  Some think this to be anything from world peace or an achievement in science or space travel.

One popular idea is that the ship Voyager will be the ship that will complete this task.  It is the farthest man made object from the sun, and whats more is it is about to leave our solar system.  If this is true then maybe it wont be to long till we meet the little gray men.

till next time.
