Fermi Paradox

Updated: Apr 22

The observable universe is about 90 billion light years in diameter and there are trillions of galaxies floating around. The milky way galaxy is around 100,000 light year in diameter, which has more than 100 billion stars in addition to it there are millions of sun like stars that have their own solar system. Researchers had discovered nearly 10 million earth like planets and there are chances of alien life existing on it.




Okay so let’s assume that there are 10 million earth like planets and some billion exoplanets that are revolving around a star somewhere in the milky way galaxy. Filtering all the obstacles, we get nearly 2 million planets that are habitable to support life. These planets have alien life in it with different civilizations and solar systems, some of the civilizations may be consider as type 1 civilization (the civilization that can harness all of planet’s resources) and they are very advanced in their science and technology, on another side of the galaxy let us assume there’s a type 2 civilization (the civilization that can harness resources from its star) and they are capable of building spaceships and can travel across their solar systems. Last but the least there is a type 3 civilization on some corner of the milky way galaxy (type 3 civilization can harness the resources of the whole galaxy) that more advance than type 2 civilizations and they are capable of interstellar and intergalactic travelling. All these 3 civilizations are very advanced in their own. They have advanced communication system and a very advanced deep space network and they are able to eliminate their enemy civilizations. But till now w
