Albert Einstein was fond of saying that “Imagination is everything. It is the preview of life’s coming attractions.” What if our world, our universe, following Einstein’s insight, is the result of a quantum-physics experiment performed by some ancient hyper-advanced alien civilization. A civilization that, as astrophysicist Paul Davies speculates, may exist beyond matter.

In The Eerie Silence: Renewing Our Search for Alien Intelligence Davies writes: “Thinking about advanced alien life requires us to abandon all our presuppositions about the nature of life, mind, civilization, technology and community destiny. In short, it means thinking the unthinkable. Five hundred years ago the very concept of a device manipulating information, or software, would have been incomprehensible. Might there be a still higher level, as yet outside all human experience?”

Within an infinite space of current cosmology, suggests the University of Chicago theoretical physicist, Dan Hooper, there are inevitably an infinite number of universes that are indistinguishable from our own. “Yet some of the regions within the multiverse,” says Hooper, “are likely to be alien worlds with unknown forces and new forms of matter along with more or fewer than three dimensions of space –worlds utterly unlike anything we can imagine.”
