To start, I'm not at all knowledgeable in physics; completely ignorant. Now, I know I could go ahead and research this on my own, but I've always felt like asking an actual interactive human being is the best way to gain direction compared to a lifeless search engine or book. So how do we know of the vastness of the macrocosm and microcosm alike? From a philosophical standing, this absolutely boggles my mind, and stimulates my spirit. Yes, I know because this is what we observe through our senses aided by instruments. But I would like just a little bit of direction to what I should research to thoroughly understand how we can come to perceive something so transcendent and beyond our self, from an integrated view that is both scientific and philosophical.
