Recently I was asked this simple questions, " Do aliens exist?".
Unfortunately there is no simple answer to such a simple question. Only suggestive answers which strangely work both in favour and against the very notion that WE MIGHT NOT BE ALONE IN THE UNIVERSE.
Let us look how.
The Universe (I mean the observable universe) is around 14 billion light years in radius. Now let us look at the exact numbers that you and me can comprehend. 1 light year is approximately 9.5 trillion kilometers or 95 followed by 11 zeros or 9500000000000 kms. And the radius of universe is 14 billion times this number which is like 1400000000000000000000000 kms. This distance is roughly onr thousand billion times the distance between earth and sun. Phew!!!!!
And this is just the radius. Now if we ASSUME the universe to be perfectly spherical then the volume of the universe will be approximately 42000000000000000000000000000000000000000000000000000000000000000 cubic kilometers. Pheeeeeeeeeeeeeeeeeeewwwwwww!!!!!!!
Well that I suppose is enough rough mathematics. Now lets come back to some logic.
In such a huge observable universe our solar system is just a dust particle in the entire deserts of the Earth. This Universe contains approximately a thousand billion galaxies each containing a hundred billion stars which adds up to around 1000000000000000000000000 stars of which Sun is just one star. Many stars have planets around them and they might have different chemistry working there.
In such a big universe where stars abound and planets too, how can we assume that Earth is the only planet on which Life can exist?????
In my personal opinion Aliens can exist and may be. they do exist.
But i am not sure. We have never been contacted by aliens before. Or DO WE THINK SO??? More about alien contacts in some other blog.
As of now I can only say that just because we can't see something doesn't mean it doesn't exist. Aliens might as well exist because the sheer size of the universe defies the logic that they don't exist.
