Forever Unknown

When I think of the universe, I think of something that is so vast and large that there is no possible way to make it all-knowing.  There will always be something that we won't know about it.  Today the quest of almost every country is intelligence; everyone wants to know more.  That is why, in my opinion, that we are so interested in the universe. It is so enormous and there is so much to know that it peaks everyone's curiosity.  

It makes me wonder about the practicality of it.  Why do we need to know so much about the universe? Maybe so we can avoid or prepare for a meteor, or maybe because eventually people will have to live in space for long periods of time.  Packing For Mars shed light on many aspects of space that I had never thought about.  

I think the Universe contains many large-scale objects that are very different from the objects and compositions that we are accustomed to, which is why we are so intrigued by it.  The sun and planets are a complete different composition of the Earth (or at least the ratios of the elements are different).  They are big, beautiful, different, and very far away! I think the challenge of figuring out these foreign planets is what pushes countries to be competitive in finding out anything and everything about them.  

I could describe the Universe with the use of the objects is contains--stars, planets, moons--or by the mystery of the unknown, or by the contents of whats known.  But no matter how it is described, it is intriguing and people are curious about it.  They will forever be curious, because it will forever be unknown.
