Time Travel in Einstein's Universe: The Physical Possibilities of Travel Through Time
In this fascinating book, the renowned astrophysicist J. Richard Gott leads time travel out of the world of H. G. Wells and into the realm of scientific possibility. Building on theories posited by Einstein and advanced by scientists such as Stephen Hawking and Kip Thorne, Gott explains how time travel can actually occur. He describes, with boundless enthusiasm and humor, how travel to the future is not only possible but has already happened, and he contemplates whether travel to the past is also conceivable. Notable not only for its extraordinary subject matter and scientific brilliance, Time Travel in Einstein’s Universe is a delightful and captivating exploration of the surprising facts behind the science fiction of time travel.

My brother and I have been talking about time travel since we were very young children. Often any large box that fell into our hands became modes of traveling to the past or the future. While I became an English teacher my brother has retained this bent and became an engineer. In every conversation through our lives well into adulthood we still talk this possibility. Our recent discussions have been around JR Gott's book about time travel possibilities and theories. It is highly accessible and very entertaining. The models are well defined and easy to understand with great pop culture references like the theroy of self-consistancy being applied to Bill and Ted's Excellent Adventure. It is a great read.
good book, I've owned a copy since i was in the third grade, and i liked it, even if i only read the beginning about all of the sci fi movies about time travel and looked at some of the diagrams. but now i am writing a research paper on it, and i find it really rather interesting. i have found that their are some mathematical errors, like the diagram on page 45/46 he says that a rocket traveling at 80 percent of the speed of light, will travel four feet per nano second. also on page 44, and in the diagram on page 45 he says that light travels one foot per nanosecond. he also says that the light clock mirrors are three feet apart, meaning that it will take three nanoseconds to travel before it reaches the other mirror, so how does he arrive at the "fact" that if he is traveling at only 80% of the speed of light, he travels at 133.3% percent of the speed of light? the four foot number should be 2.4 (80% of the speed of light in feet per nanosecond) i believe he based all of his math on his incorrect figure, so beware of the math
if i did this math wrong, shoot me an email @;
