Sean Carroll: Distant time and the hint of a multiverse


A very entertaining TED talk from Sean Carroll, a theoretical cosmologist specializing in dark matter and general relativity.
We find ourselves, not as a central player in the life of the cosmos, but as a tiny epiphenomenon, flourishing for a brief moment as we ride a wave of increasing entropy. Purpose and meaning are not to be found in the laws of nature, or in the plans of any external agent. It is our job to create them. One of those purposes — among many — stems from our urge to explain the world around us the best we can. If our lives are brief and undirected, at least we can take pride in our mutual courage as we struggle to understand things much greater than ourselves.
