For centuries, humans have asked the question of the presence of intelligent life on other planets. But it was only recently when humans could finally search for a concrete answer to this question and initiated research and other studies to find out intelligent life in the universe using radio telescopes. These devices help us listen to radio messages when transmitted by alien colonies.
So what could be the possible outcome of these initiatives? What would humans do if such a sound is detected and our search for intelligent alien life succeeds? According to experts, it is highly unlikely that we would be seeing the typical type of aliens we often see in space movies, and the reality is going to be vastly different from our expectations and imaginations.

If we suppose, for the sake of argument, that life began on other planets and it followed a similar evolutionary process like that on Earth, which is also highly unlikely to happen, then it is not certain that the intelligence of extraterrestrial species is at the same pace as it happened on Earth. If it is light years behind the technological advancement we have on Erth, the radio telescopes couldn’t possibly catch any signs or radio waves from these planets, and they wouldn’t reveal their presence to us.
But if it is a star older than the sun itself, then life and intelligence would have started there billions of years ago and thus, civilization there would be way ahead of us.

As we and the world around us evolves, we gain further intelligence and our species as a whole becomes more intelligent. Deaths and births of stars in the galaxy will eventually slow down, as the Milky Way will crash with the Andromeda Galaxy in a billion years. After the crash, debris from our Milky Way and the Andromeda would most likely clump together to form one amorphous galaxy, while other debris would simply move away and disappear.

Human Intelligence And Limitations
Overall, the physical reality and post-human intelligence could be vastly different than what we had ever imagined. More intelligent extraterrestrial species could have developed supreme intelligence and could have the ability to simulate living things with their superior computing powers. For all we know, we can never be able to correctly predict their intelligence and motives. So, the silence that the radio telescopes are currently facing could be the sign of absence, or the presence, of a greatly intelligent extraterrestrial species.
