From the remarkable Brain Pickings blog comes this wee video about the origin, and expansion, of the Universe. From Edwin Hubble's observation that galaxies are moving away from each other came the theory that, at conception, the Universe started as a "monumental explosion of an infinitely small and infinitely hot point." In other words, The Big Bang. I don't have any trouble accepting the theory. I can even get my mind wrapped around the concept of that infinitely small and hot point. Where is lose my way is, where did the field (space) that all these celestial bodies are expanding across come from? Just wondering. Enjoy the video.
