From the Edge of the Universe to the Inside of a Proton

“But we should count ourselves lucky; there have not always been 62 orders of magnitude of universe to explore, and there won’t always be. As Scharf explained, ‘If you turn the clock back far enough to the Big Bang, obviously there was a time when the number of scales that were causally connected were fewer, and space itself was smaller.’ Likewise, ‘if you extrapolate 100 billion years into the future, assuming the current accelerating expansion, it will be essentially impossible for us to see anything much beyond our galaxy or our local group of galaxies.’ Scharf said this seems to mean we’re living at a special time. And he wondered, ‘Would someone in the future be able to figure out how the universe works?’”
