The universe is a vast, and complex terrain spanning light years of distance. A speck of that universe is the planet Earth, and its denizens, of even tinier proportion. A part of understanding the universe is understanding ourselves. It is through our mind that we garner a deeper knowledge of the universe, and by understanding our brain, we curate information on our medium of understanding. Our species as a whole has a deeper comprehension of our universe than we do our brains, the very entity with which we use to master the universe and all its components. We have more knowledge about the depths of space than we do the cognizance of our mind. To understand the universe is to understand ourselves. Simply due to the fickle nature of our brains, we cannot know for certain if what we know about the universe is true from an objective standpoint. The only vessel we have to understand the universe is our brain, which we don't entirely understand its complexity and all its flaws as of yet. The very way we see and interpret information may be only a fragment of what is truly out there. The more we understand our minds, the more we can know about the universe and its beauty. It is for those reasons, that I choose the field of psychology as my future career choice, especially the realm of research. Our brains are special vessels of functioning, more mysterious than the universe itself. Understanding the brain requires a combination of many fields of study, such as mathematics, physics, and biology, all of which are used to understand our universe more deeply. By understanding psychology and neuroscience, we understand with greater complexity how life forms, chemical reactions, and how what we believe about ourselves may not be what we expected. Another grand mystery of the mind is the experience of emotions. We know that emotions are experienced because of chemical reactions in the brain, but why those chemical reactions cause what they do is still a topic of study among neuroscientists and psychologists alike. It is a part of understanding our evolutionary development as well, as to why we evolved to feel emotions in the manner we experience them. Our emotions are a vessel to understanding as well, not just of ourselves and our social apparatus, but our knowledge of the universe, and our place in it. Without philosophy, intrinsically tied to emotion and the human desire to explore, we would have no foundation for our understanding of the universe. It is for this reason, that understanding neuroscience and the psychology of our experiences are imperative to the understanding of the universe. We need to know ourselves to know about the world around us, and perhaps that is the greatest mystery of all.
