Five hundred years of science have liberated humanity from the shackles of enforced ignorance. - Lawrence M. Krauss

But relying on invisible miracles is the stuff of religion, not science. To ascertain whether this remarkable accident was real, physicists relied on another facet of the quantum world. Associated with every background field is a particle, and if you pick a point in space and hit it hard enough, you may whack out real particles.

Reality is that which, when you stop believing in it, doesn’t go away.

one’s universe would appear very different from the vast bulk of space around it, which would still be inflating. In this picture, inflation is eternal. Some regions, indeed most of space, will go on inflating forever.
