Psychology raises some extremely interesting questions about self-exploration. When reviewing some of the material, we often revert to our own minds and explore areas of thought within ourselves that we had previously never reached before. The BBC video raises an interesting point in comparing the outside universe and exploring the world as equivalent to exploring our own minds. Think of all the areas we haven't even begun to comprehend yet. Look inward for a second and realize how much area, space and time we travel within our own skulls. We can time travel through memories, comprehend our own selves as sensitive creatures, comprehend the outside world, but what else is going on in there? If we only use 10% of our brains, it's hard to even imagine what else we are capable through accessing the other regions. It's mind-blowing, really, to understand that the greatest frontier of exploration is not planets and stars in our physical universe, but comprehending who we are, what happens in our heads, and our awareness of self. Take a second, right now, and realize everything going on around you that you are aware of, and realize how truly incredible you are.
