Do you remember the “Jaddu” from Koi Mil Gaya? Well, it was the Indian version of Steven Spielberg’s 80’s take on alien “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 the 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 were: 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 the 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 probability of the existence of extraterrestrial 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 to find alien life.
FIRST ARGUMENT OF PROBABILITY FOR ALIEN LIFE:
His thought was that: Our milky way galaxy has billions of stars older than our solar system. Some have Earth-like planets in them. So on the calculation of the high probability of Earth-like planets, the probability of life increases. Hence the probability of rising 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 sextillions (7×1022) in the observable universe; so there must be someplace resembling earth which harbours intelligence species.
SECOND ARGUMENT OF PROBABILITY:
- It’s also possible that if an alien civilization exists and they’re really advanced, then they might colonize new habitats by seeking new resources from intergalactic 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 the 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 extra-terrestrial civilization.
So the Fermi paradox really questions the 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 alien life for entertainment?
Do you think these little green men actually exist? If yes ,then why? Feel free to share your thoughts on alien life.
