Few concepts are as exciting, or as scientifically challenging as the possibility of time travel.

In this book, the author reveals the nature of recent, breakthrough experiments that are turning this fantasy into reality. Here she explores the often riveting motives of the people involved in this quest, the consequences for society, and what evidence might indicate that it has already become reality.

The author has done a good job of mixing all the batty ideas for time travel that have sprung up over the years with the real possibilities for breaking the time barrier. In a sense, she points out, anything that moves is time travelling. She also introduces the confusing complexity of quantum theory and general relativity that have opened up the possibilities for time travel.

She talks about various time travel theories and how the basic research into the area was started by Tesla. The author documents the evolution of research that began about a century ago, in which scientists from Marconi to Edison worked to create a real time machine, to modern scientists. The book is truly an entertaining combination of proven and unproven science.
