""One of the most remarkable things astronomers have found as they have looked ever farther out in space (and thus also further back in time) is that the laws of physics that apply here on earth also apply, as far as we can tell, everywhere else we have looked. There is no "diversity of physics" across the universe in the way that there is a diversity of human cultures around the world.

In the micro-world of quantum physics, the most dramatic demonstration of interconnectedness is described by Bell's theorem. In 1964, John Bell showed that quantum theory predicted that any two particles that originated from a single source (such as two electrons born out of an energetic collision), would later behave as if they maintained some kind of on-going non-local connection. This connection can be revealed by measuring some property of each particle, such as the spin of each electron. It is instantaneous and unaffected by time or distance. According to Bell, these measurements should be more highly correlated than if the two particles were truly separate. Many experiments have now confirmed Bell's prediction.

The implications of this are profound, since all matter comes from essentially a single source – the Big Bang. Thus Bell's theorem implies, at a quantum level, that the physical world is an inseparable whole. The old Newtonian idea that world is made up of separate objects that occasionally collide, but otherwise lead independent existences, turns out to be only a convenient approximation, applicable in only some situations.""
