There are hundreds of billions of stars in one galaxy, all orbiting around its center. There are over 30 galaxies in our Local Group of galaxies. The Local Group is locate at the edge of the Virgo Supercluster, which is a collection of about 100 other groups or smaller clusters of galaxies like our own. This is still a tiny aspect of the universe at large when you consider one estimate for the total number of galaxies as 500 billion! If humans were the only intelligent life form in all this, wouldn't it be such an incredible waste of space? Whats the chance? Lol. Yeah, I know. So... you just gotta know that there are so many alien life forms out there that are just as intelligent as us! I wonder where we stand. How advanced are we compared to the universal average?
Note: The word "universe" is derived from the Latin root "unus" (one) and "vertere" (turning).
Wrt the meaning and purpose of life and reality as a whole - there is a sort of universal "blind spot" that gives it all away, so to speak. 😉
Metaphor: Just as you cannot see behind your head, or grab the back of one hand with that same hand, so to, there will always be a part of the Universe that remains a dark mystery to the other part thats doing the "looking".
In this sense, to the extent that "we" are the universe "looking" or studying itself, you could say that the universe MUST expand in order to escape the telescopes through which we, who are it, are trying to capture it, which is us! 😂
