A friend of mine recently wanted to hear my take on the famous three-body problem. A couple of days after sharing my views on the fascinating physics problem, I got a request from a regular reader to write about it as well. I thought to myself:

“Huh! What an interesting coincidence?!”

Well, I could not have been more wrong. It turns out that there is a new science-fiction series that goes by the same name (based on a book) that launched both of these people into investigating this problem.

Needless to say, being a science lover, I had to check the series out for myself. Although I enjoyed the work of art, I must confess that I was a tad bit disappointed that it did not go into the topic in detail.

That is where this essay comes in. My goal with this work is to present you with a beginner-friendly introduction to the three-body problem and the rich history surrounding it.

By the end of this text, you should not only be able to enjoy a conversational understanding of the topic but also appreciate the intricate, hard work put in by generations of physicists, mathematicians, and astronomers that has led us to our present understanding of the problem.
