John Archibald Wheeler, high priest of quantum mysteries, suspects that reality exists not because of physical particles but rather because of the act of observing the universe. "Information may not be just what we learn
about the world," he says. "It may be what makes the world."
Our observations, he suggests, might actually contribute to the creation of physical reality. To Wheeler we are not simply bystanders on a cosmic stage; we are shapers and creators living in a participatory universe.
Wheeler conjectures we are part of a universe that is a work in progress; we are tiny patches of the universe looking at itself— and building itself. It's not only the future that is still undetermined but the past as well. And by peering back into time, even all the way back to the Big Bang, our present observations select one out of many possible quantum histories for the universe.
"I have a hunch that the universe is built like an enormous feedback loop, a loop in which we contribute to the ongoing creation of not just the present and the future but the past as well".
