One point made in the lectures that stuck with me the most is that the Big Bang actually made no sound at all. Growing up, I had always been under the impression that the Big Bang caused an amazing sound. I always envisioned this little ball exploding and expanding at an extremely loud, beautiful moment. I had always been taught that the Universe started from this miraculous explosion, sparking all things that we know today, but that was not the case. A lack of friction due to a lack of other matter in the area meant that the Big Bang was actually a silent phenomenon, contrary to popular belief and understanding. On a deeper level, a lack of substance around a certain event may cause it to go unnoticed, not be as recognized nearly as much as it should be. Throwing paint onto a canvas versus just into the air cause very different outcomes, however they may begin in a very similar way. Art can be good no matter how many or how few people actually ever lay eyes on it, but in order for it to become an important piece in the world, it must have substance around it that allows it to be recognized. Power comes from a mix of substance and surrounding, the Big Bang lacked one of those, and thus doesn’t get recognized properly for what it actually was, a silent explosion that started it all.
