“Our cosmic environment could be richly textured, but on scales so vast that our purview is restricted to a tiny fragment; we’re not aware of the ‘big picture’, any more than a plankton whose‘universe’ was a liter of water would be aware of the world’s topography and biosphere. It is obviously sensible for cosmologists to start off by exploring the simplest models. But there is no more reason to expect simplicity on the grandest scale than in the terrestrial environment—where intricate complexity prevails.”
