Existence of Intelligent Life


If you are one those people who believe that we are the only intelligent creatures in the entire, ever expanding Universe, you are too arrogant, primitive and naive.

Given that we can only see 0.000003% percent of the Milky Way and have been able to see and understand, to the best of our abilities, just only a tiny fraction of our own Galaxy, it would be too ignorant of us to imagine that there is no other intelligent life in the Universe.

I have been a topic of discussion for my unrealistic theories quite a few times. But the truth is, how does anyone know if it is real or unreal?

My theories are as much real as they are unreal. They are and will continue to be in a quantum state until proved otherwise.

But don’t ever interpret this in the wrong way. This in no way is a belief. This is a theory. Don’t start comparing my theory and fascination of the existence of other intelligent creatures in the Universe to the fiction of god.

Existence of Alien life in the Universe is a theory based on facts and data and a certain degree of imagination and calculations.

Based on Drake’s Equation:

The Drake equation is: {\displaystyle N=R_{*}\cdot f_{\mathrm {p} }\cdot n_{\mathrm {e} }\cdot f_{\mathrm {l} }\cdot f_{\mathrm {i} }\cdot f_{\mathrm {c} }\cdot L}

where:
N = the number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);

and R = the average rate of star formation in our galaxy
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fl = the fraction of planets that could support life that actually develop life at some point
fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space

Even if we are the fastest growing species in our galaxy, we are still at least over a 100 years away from reaching a point where we might be able to consider the possibility of extraterrestrial communication.

At present, in the galaxy that measures 52,850 light years, it is a theoretical possibility that there exist at least 200 civilizations who are capable of inter-planet communications at this very moment.

They are obviously too far from us and with not very highly efficient equipment to communicate at such a great distance, but they are there.

The frequencies would vary; there would be differences in equipment; and a hundred other factors.

But I am sure, the day we are able to chart even 1% of our galaxy, we’ll find at least 800-1350 planets with evidence of life. Some more and some less intelligent than us.

P.S. We are not alone.

  1. I am 75 years old. I have been interested in this subject most of my life, but I do not see any empirical evidence to justify any kind of position on this question, either life or no life. When there is no empirical evidence to base probability on its just a guess or a hope.

    That does not mean we should not be looking, I think we should be looking and while guesses and hopes provide a direction and focus to look for, they can also become preconceived blinders to miss it when appears.
