Before you read any further, stop and close your eyes for a moment. Now consider the following question: for the moment your eyes were closed, did the world still exist even though you weren't conscious of it? How do you know? If this sounds like the kind of unanswerable brain teaser your Philosophy 101 professor used to employ to stretch your philosophical imagination, you might be surprised to discover that there are actually physicists at reputable universities who believe they have answered this question—and their answer, believe it or not, is no.
Now consider something even more intriguing. Imagine for a moment the entire history of the universe. According to all the data scientists have been able to gather, it exploded into existence some fifteen billion years ago, setting the stage for a cosmic dance of energy and light that continues to this day. Now imagine the history of planet Earth. An amorphous cloud of dust emerging out of that primordial fireball, it slowly coalesced into a solid orb, found its way into gravitational orbit around the sun, and through a complex interaction of light and gases over billions of years, generated an atmosphere and a biosphere capable of not only giving birth to, but sustaining and proliferating, life.
Now imagine that none of the above ever happened. Consider instead the possibility that the entire story only existed as an abstract potential—a cosmic dream among countless other cosmic dreams—until, in that dream, life somehow evolved to the point that a conscious, sentient being came into existence. At that moment, solely because of the conscious observation of that individual, the entire universe, including all of the history leading up to that point, suddenly came into being. Until that moment, nothing had actually ever happened. In that moment, fifteen billion years happened. If this sounds like nothing more than a complicated backdrop for a science fiction story or a secular version of one of the world's great creation myths, hold on to your hat. According to physicist Amit Goswami, the above description is a scientifically viable explanation of how the universe came into being.
Goswami is convinced, along with a number of others who subscribe to the same view, that the universe, in order to exist, requires a conscious sentient being to be aware of it. Without an observer, he claims, it only exists as a possibility. And as they say in the world of science, Goswami has done his math. Marshalling evidence from recent research in cognitive psychology, biology, parapsychology and quantum physics, and leaning heavily on the ancient mystical traditions of the world, Goswami is building a case for a new paradigm that he calls "monistic idealism," the view that consciousness, not matter, is the foundation of everything that is.
