Do you remember the “Jaddu” from Koi Mil Gaya? Well it was the
Indian version of Steven Spielberg’s 80’s take on aliens “Extra
Terrestrial”. But I think it’d be an insult to Steven Spielberg as the so-
called Indian version is nowhere near the hollywood original.In the
Indian film ,the alien is called by some crazy scientist through antenna of some TV! I mean are you kidding me? Well ,this is how we see aliens in TV,movies and all; Green little creatures creating some weird buzzing sound with really unusual big feet. Are they really like that or are they more than what we think or are they so alien that we can’t even recognize them as living beings?
The question had been doing the rounds in the science community for a long time after famous Italian-American Physicist Enrico Fermi asked a question during lunch with other scientists which was: Where is everybody? Where are all the aliens? It
was asked on a light hearted note by Fermi after coming to know about some UFO sightings in United States.
Fermi was one of the physicists who could work out calculations using very simple and out-of-the-box methods. So he calculated the probabilty of existence of extra-terrestrial civilization
using his own methods from which he concluded;not concluded
exactly,but further reached some more investigative questions which
were known to be Fermi Paradox.
FIRST ARGUMENT OF PROBABILTY:
His thought was that :Our milkyway galaxy has billions of stars older
than our solar system.Some have earth like planets in them .So on
calculation of high probabilty of earth like planets ,the probability of life
increases.Hence probability of rise and duration of high-class
technology of that civilization also increases.So he concluded that on
the basis of these calculations we must have been visited by any higher
intelligence species a long time ago .It’s kind of intriguing as there’re
like 200-300 billion stars in our own milkyway galaxy and 70
sextillion(7×1022) in the observable universe ;so there must be some
place resembling earth which harbours intelligence species .
SECOND ARGUMENT OF PROBABILITY:
It’s also possible that if any alien civilization exists and they’re
really advanced ,then they might colonize new habitats by seeking
new resources from intergallactic space and colonize their solar
system to expand their civilization which we are only thinking
about right now( e.g. Colonization of Mars).
There’s also possibility of our inability to look for the right signs
i.e. whether we know what are looking for or not.I meant do we
actually know what we are searching for when we do research on
So the Fermi paradox really questions existence of those little
green men ,and we can’t also point out anything wrong with his
argument.Those are really obvious questions and it’s obvious that
even we as small children also at some point asked ourselves or
our friends that in such a vast universe ,are we really
alone?Sometimes it really feels kind of weird as why only
earth?Why only our earth has the potential for habitation ,that
too in such a huge universe? There must be something out there
in the dark skies which we can’t see or which we aren’t seeing or
what if they’re actually waiting for us to develop to their
standards to shake hands with them in the galactic community or what if we are in a computer simulation being used by those
aliens for entertainment?
Do you think these little green men actually exist? If yes ,then
why? Feel free to share your thoughts.
