We Can All Time Travel, says physicist Fred Alan Wolf. In fact, we may already do so. He cites Hindu yoga systems to show how we can defeat time through any spiritual practice-such as meditation-that dissolves the ego. He shows how quantum physics supports this claim and explains in simple terms such phenomena as black holes, wormholes, and parallel universes. Wolf's fascinating scenarios help us imagine what traveling to the past or the future through mind yoga would be like. Provocatively, he suggests it might even improve the quality of our lives. Time travel could, for instance, clarify our sense of self and purpose, reverse aging, and provide wisdom for the benefit of our entire community.
