The astonishing discoveries made by modern physics - imploding black holes, ghost-like quarks, and the odd rules governing quantum mechanics - have transformed our image of the physical world. A growing number of writers assert that such discoveries also demonstrate the existence of a non-physical, spiritual world, a world that permits a wide variety of paranormal and psychic phenomena. What exactly has physics shown us? Is there a world that transcends the sphere of the senses? Millions throughout history have thought so, but the existence of such a world is still accepted on faith alone. The tools of science have revealed no proof of spirits, ghosts, or supernatural phenomena. This book critically examines theories of a transcendent reality in terms of all that is currently known about matter at its most fundamental level. Victor J Stenger gives a provocative, often amusing history of psychic research and occult beliefs, offering a convincing rebuttal to those who attempt to link physics to mystical truths. Stenger examines a number of well-known paranormal claims and shows how they can be explained without resorting to supernatural or psychic hypotheses. Discussing quantum theory and relativity, he demonstrates that these concepts actually invalidate paranormal claims and that there is no scientific basis for a universe other than one composed of observable matter. The human species has always lived under the assumption that supernatural forces determine destiny. Can our lives retain meaning when this assumption seems unfounded?
