WHY WE HAVEN'T MET ALIENS?

In 1950, the Nobel prize winner Enrico Fermi raised a very interesting question that apart from humans, where are the intelligent beings who live in the universe? Whenever we look at the universe, we get the number of countless planets like Earth on which millions of extraterrestrial civilizations can exist, scientifically the universe has more than 13 billion years of existence. The time of 13 billion years is enough to contact advanced civilizations, so, why did they not come directly to meet us, this question of Enrico Fermi in history became famous by Fermi paradox, which made humans think that why the Alien civilizations present in the universe do not contact us, where are they? In this article, we will try to find the answers to these questions, Here we discuss the all the theories that are based on different beliefs and also have differences among them, but all of them will definitely help in finding the answer to this question. Lets discuss them,

1. Rare earth hypothesis

Rare Earth Hypothesis tells us that the geographical and biological factors that make life on our earth are very unlikely to occur anywhere else in the universe in the same order, according to this theory, all the gradual events that took place on earth, because of which the life exist here, all of them are very unlikely to be on any other planet, that is, we could not meet the alien civilizations because they are not there in the universe or their number is very less.

2. Extremely developed civilization collapses after some time.

According to the Great Filter theory, Alien civilization exists in the universe , but despite being technologically advanced, they will have to face some disaster that will either completely eliminate them or technically push them back thousands of years and will not be able to reach that point where they can make contact with any other civilization.

3. They've moved out of the universe

John Smart's theory tells us that developed alien civilization ever existed in our universe, but they evolved so much and left our outer universe and moved to other dimensions for better possibilities. Means that they must be living in those dimensions which we can only imagine.

4. Earth isn't as special as we think

Alien civilizations are interested in our earth, it can also be our illusion. Out of the countless planets in the universe, they may be more interested on planets with better potential than our earth, that means our earth is not special.

5.There signals and our similarities

The radio signals we send may be useless to them, they may not use technology like radio signals, they may send messages to us through some other means like gravitational waves and neutrinos which which may be beyond our scientific understanding.

6. We're living in a virtual reality

The most disputed topic of Fermi Paradox, which is debated among researchers say's that the world in which we live can also be a illusion of our eyes.This whole theory starts with just one question, how do we know that what we are seeing is true?And we can't meet them because they don't exist in this virtual world.
