Physicists are changing how we think of empty space, i.e. a vacuum, to explain how the universe could have come from ‘nothing’. Empty space, it turns out, may not be empty at all. One of the leading proponents of this view, cosmologist Lawrence Krauss, distinguishes between three different kinds of empty space. One, which the Greeks knew, is a space where nothing is seen to exist but which we now understand to be teeming with energy and magnetism. From there, things get strange, then they get incredibly strange.

How the Universe Came from Nothing | IdeaFeed | Big Think
Carl and I were just pondering this last night. I was trying to make sense of how there can be galaxies that give the appearance (to our human eyes) of being contained and having edges, yet that confinedness might also suggest that there is space (or emptiness) between them… but how? Or why? Or is it space that we simply cannot make sense of from where we sit? And how do “somethings” come from so much “nothing”? (Admittedly, I’m always using my poetic mind to imagine such questions, so maybe they aren’t framed in the most scientific way, but still…)
