Fermi Paradox! Where are all the Aliens?

Are we alone?

Fermi Paradox

There is an estimated 200-400 billion stars (2-4 x 10¹¹) in our Milky way galaxy only and as Hubble reveals there is all in all 100 billions galaxies in the visible universe and this number is likely to increase to 200 billion as the telescope technology in space improves NASA Is Sending a Life-Looking Drone to Saturn’s Enormous Moon Titan.

In November 2013, astronomers reported based on kepler mission data that there could be as many as 40 billion earth like habitable exoplanets revolving around stars and red dwarfs in milky way galaxy alone. Out of which 11 billion may be orbiting around the sun like star. Keeping these facts in mind the possibility of potential habitable Exoplanets is pretty good.

Earth may not be so Special

So where are all the aliens inhabiting these planets? Are they smarter than us? Answers to all these questions lies in Fermi Paradox, named after Italian Physicist Enrico Fermi, famous for creating the first Nuclear reactor. He came up with a theory during lunchtime, which made many physicists scratch their head for a long time.

First Aspect of the Fermi paradox is that in Lunar Eclipses and Photovoltaic Eclipses this vast universe with about 40 billion habitable planets in just one galaxy i.e Milky Way, the possibility of extant alien civilization is undeniable. This assumes the mediocrity principle that Earth is a typical planet

According to Ernico Fermi, “Any Civilization with a modest amount of Rocket Technology and an Immodest amount of Imperial Incentive could rapidly colonize the entire galaxy”.

Beware! An all out war is on the way

Search for Extraterrestrial Intelligence (SETI) published on its website that within  On Icy Moons, Alien Life Could Go along with the Move of Ocean CurrentsTen Million Years, Every star system can be brought Under the wing of an Empire. It may sound that ten million year is a very long time but considering the age of universe which is approximately 13.772 billion years, 10 million years is not that long time.

The second Aspect of Fermi Paradox is based on probability, assuming that intelligent life has a tendency to overcome scarcity and colonize new habitats. It seems quite reasonable to think about a civilization technologically advanced enough to seek out resources in space and their star system and subsequently Other Star System.

Why they haven’t reached out yet

There is no Evidence of Such colonization around us,Bizarre ‘Fettucine’ Rocks Could Assist Us Spot Life on Mars  Which arises a conflict requiring a definite answer. Michael Hart, who believed that we are the only advanced civilization in Universe tried to Outline Four different Possible Solution for the Paradox.

• Aliens never came because of a physical difficulty “that makes space travel infeasible, ” which could
  be related to astronomy, biology or engineering.


• Aliens chose never to come to Earth.


• Advanced civilizations arose too recently for aliens to reach us.


• Aliens have visited Earth in the past, but we have not observed them.

For an advance Civilization to grow and prosper, It requires a lot of time. It may also be possible that life is too fragile to survive that long. Accoding to Drake Equation which attempts to figure out the number of advanced civilization in milky way that seek to communicate Barnard’s Star Planet Might Not Be Too Chilly for Life After All each other is as many as 10,000 . Who Knows One day we might be able to reach one of them or vice versa
