What does the night sky teach us about the universe? (3.0) 21 May, 2020   


3.1 Introduction

3.2 Fermi Paradox

3.3 The Great Filter

3.4 The Last Section


In the last volume, What does the night sky teach us about the universe? (3.0)  we will be questioning 2 major things. Keeping it clean and simple. How would it be like to live with other life forms? And, what is the basic requirement for life to occur?

These are also named as The Fermi Paradox and The Great Filter theory.


So, what is the Fermi Paradox?

Well, according to the fermi paradox, soon after the big bang, many events occurred. Our Earth which has life was born 4.6 billion years from present. Research says that there will be at least one planet which was born 8 billion years ago which could also consist life.

Basically, the theory suggest that there could be other life forms in the universe, some could even be more advanced than us.

Well, if this is true, then why were so many signals sent to space unanswered? Are they much more advanced than us, for them to feel we are puny, or are they so primitive, they still can not receive our signals?

It is hard to explain, but maybe this video will answer them all for you,

Although the second part of the video, only explains what happens, if we ever encounter another life form, i recommend watching this video for a better understanding.


Of course, it would be fascinating to have other life forms, but are they really there?

Well, of course there are many planets that could support life. For example Mars could support life , but, it does not as of yet.

There can be planets that COULD support life. So, obviously, the right distance from sun and water alone wont help support life. There is something more important, something more unimaginative.

This is The Great Filter Theory.

According to this theory, every life form has to encounter a great filter during its course on the timeline. The job of this filter to eradicate those type of life forms that bring in chaos and instability to the universe.

From the above image we can see we have 2 cases. Either we are an advanced species that have already crossed the stage of the great filter. 

Or, we may be walking down the aisle right now,

Now to the base question, is it good to have other life forms?

Well, the answer is no. Because if there are other life forms, then we are still in that part of the great filter theory, where we are competing with others to be the Type III civilisation.

BUT, if we dint find another civilization, it could mean we are that unique and rare life form to have crossed the great filter.


So this leads to a series of questions and conclusions. So what is the great filter? Is it God, some kind of religious overlord or maybe the sun itself? Why is it we truly cant have other species? And what makes us special to believe we are the Type III civilization?

These are questions, probably the night sky will keep to itself. A secret we need to unlock some day. A secret that only civilizations so advanced will ever find answers to.

Let us hope during our lifetimes, we can ever encounter a big discovery that we can think of always when we look up in the night sky.

So, next time you look up into the night sky, try remembering the 3 volumes of "What does the night sky teach us about the universe?" And you will see the universe in the whole new perspective.
