We have mastered traveling through space, but time eludes us. Not a person exists who doesn’t wish to go back in time to the past or shoot forward into the future to see what may unfold. Time eludes us, for we are trapped by the arrow of past, present and future in an order that appears fixed and unchangeable. Yet...is it really fixed and unchangeable, or is it just a matter of how our brains have been trained to perceive time? This book looks first at the enigma of time itself...how little we truly know about linear time and how it has actually changed over the course of scientific knowledge and evolution. Time is not what we originally thought it would be, and as new discoveries point to a much less fixed concept of time, we very well may one day be able to control the clock the way we control our spatial location. We may, in fact, be able to travel through time. From the earliest ideas and imaginings of science fiction authors and visionaries to the most cutting edge research into the behavior of particles and the cosmic constants that constrain time travel, we explore how close we have come from Einstein’s time dilation and relativity theories to a world of potential wormholes, parallel universes, additional spatial and temporal dimensions, the Multiverse and even bizarre particles that seem to exceed the speed of light, and open new doors to one day walking the landscape of time as we once walked upon the moon.
