We, the humans, often talk about aliens or some kind of smart artificial intelligence existing at some corner of the universe. But despite all noise, we, so far, failed to collect any evidence of existence of any aliens let alone contacting them. The central dilemma here is theFermi paradox.
The Fermi paradox mentions that the universe is very large with trillions of galaxies and billions of stars and planets. Out of these insanely large numbers, there exists only tiny fraction which contains habitable planets capable of hosting any kind of life form.
But even a tiny fraction will translate itself into a large number which indicates that there might be billions of species of aliens exist out there. Here, the Fermi paradox questions us: With so many alien species out there, why we failed to find them? Or, for that matter, why they also failed to find us?
In the above backdrop, we believe that we have not encountered any alien species so far. But, if we have to believe NASA, they have stated very categorically that “there are indications of alien life”. This disclosure may open the floodgates and may lead to a full disclosure.
NASAChief ScientistEllen Stofan informed:
“I think we’re going to have strong indications of life beyond Earth within a decade . . .I think we’re going to have definitive evidence within 20-30 years.”
Not only that, he went on to elaborate:
“We’re on the verge of things that people have wondered about for millennia. Within all of our lifetimes we’re going to understand that there is life on other bodies in the solar system. We’re going to understand the implications of that for life here on Earth.”
