I love to read science fiction, especially the classic short stories. I must admit I approached this book with some trepidation..... my "summer reading" rarely includes non-fiction, especially science.

Having said that, I am very glad this book was recommended to me. I bought it on a whim and--even though it looked daunting (lined up next to the paperback novels)--I read it cover-to-cover in three days. That's saying a LOT, as I have the attention span of a ...

Okay, about the book: I learned some things I didn't know before about relativity, I laughed at some stories of theoretical physicists at work, and got a welcome dose of time travel paradoxes. My favorite is the classic "grandfather paradox"--that is, can a time traveler kill her grandfather and so change the past? I've read about it in science fiction, but Toomey (and the physicists he talked to) offer much more complex and provocative discussions in The New Time Travelers.

I find it amazing to discover what these physicists and philosophers are theorizing and debating about. For instance, the book talks about Igor Novikov, a physicist who suggests that if a natural time machine exists somewhere in the universe and we can reach it via unmanned spacecraft, we could exploit something called the "Bootstrap Paradox" (gotta love that name for a time travel paradox, eh?) and force the spacecraft to create itself. It would carry knowledge of its own design and the location of the natural time machine from the future to us in the present.

Are they dreaming up the next science fiction bestseller? Nope. It's serious science. This is why I like the book so much. It sounds a LOT like science fiction, but these ideas been debated among theoretical physicists. All very serious, all very plausible....well, debatable, at least, which is a start. I would have been just as skeptical of virtual reality or gene manipulation only 20 years ago, so you never know.

I totally recommend this book. I honestly can't believe I enjoyed it so much, given the books normally on my summer reading list....

Anytime that I have picked up a book about the space-time continuum and quantum physics I feel that the adventure begins. Unfortunately the adventure can end quite early if the writing is thick and obscure as a tunnel that connects two black holes. Mr. Toomey's book, however, is extremely readable. In fact I couldn't put it down. He manages to explain complex ideas and theories very clearly and understandably. I enjoyed this book very much and encourage anyone with an interest in time travel to pick it up and give it a read. This is a fun book!

There have been a number of good books on the viability of time travel, most by the physicists who
have done work in the field. A chapter in Kip Thorne's excellent Black Holes and Time Warps
describes Thorne's own venture into this strange realm; J. Richard Gott's equally good Time Travel
in Einstein's Universe goes a bit further, focusing (naturally) on Gott's own work. Toomey is not a
physicist, but that may more an advantage than a liability, as he brings a broader and more
comprehensive history of the inquiry. Also, since Thorne's work appeared in 1994 and Gott's in
2001, he takes us up to date. Toomey tells the story chronologically, in the classic "scientific
detective story" fashion, and he keeps it moving, sprinkling it with examples from science fiction,
a few Escher lithographs, and plenty of diagrams. Readers seeking a real understanding of "closed
timelike curves" will not feel cheated: there is an extensive glossary, and enough footnotes and
citations to technical papers to satisfy a serious scholar. This might be the closest thing to a
definitive history of the serious study of time travel that we have so far, and it is as fascinating
a story as one could wish.

This book completely caught me off guard. Not only did I not know the extent to which time travel has been seriously considered by contemporary physicists and mathematicians, but I was taken aback by various counterintuitive and provocative themes that pop up here and there. For example, it's obviously clear that hard science has influenced science fiction writing, but Toomey brings up specific examples in which physicists actually credit the influence of an idea in story or novel in their conceptualization of spacetime. That being said, Toomey doesn't beat connections like those to death. The book moves at a brisk pace. It delves into fairly heady theories and hypotheses--e.g., wormholes, supraluminary signals, cosmic strings--but it manages to provide just the right amount of explanatory detail to keep the narrative engaging. (Who would have thought that theoretical physics would make good summer reading?) He does provide very thorough citations too (roughly 80 pages are devoted to endnotes, a glossary, and index.)

The style, subject matter, intelligence, and comic timing compare very favorably to Bill Bryson's A Short History of Nearly Everything. Of course, Toomey's task at hand is certainly more focused. In addition, Toomey is not satisfied with simply meditating on questions or sowing a sense of the awe and vastness of the universe. It's clear he wants answers. He wants his time machine. I do too.

A gripping read about what is often a daunting topic, Time Travelers takes us on an intellectual and imaginative journey through science, science fiction, and the lives of scientists. Books on these topics can often be obscure or overly fanciful. This one is delightfully alive, and Toomey is never less than careful in both the physics and speculations about time travel. A lesser writer would have fudged the facts to make room for fantasy, but Toomey builds a smart and powerful (though qualified) case for a kind of time travel that retains enough fantasy to keep the pages turning but never scrimps on the facts. Another fine effort by an excellent writer.

When I was a kid I was completely mesmerized by the Time Tunnel -- a 1960s sci-fi series about two research scientists who become trapped in a top secret portal through time. David Toomey doesn't have my beloved Dr. Tony Newman (played memorably by James Darren, in form-fitting corduroy) but his book is populated by scientists who, if not quite as sexy, are just as captivating. I found myself fascinated by the book's take on the scientific community and how it works -- how concepts evolve over time, and also, maybe even especially, how ideas can migrate back and forth between scientists and the world of science fiction. Toomey does a great job of making the science itself accessible, but for me the really careful description of how scientific insight builds over time, how epiphanies large and small, new and sometimes pretty old, accumulate and eventually become theories, was worth the price of admission alone. The politics of science research and publication is also really present in the book -- I got a good sense of how on-the-ground professional factors shape the high-flying theory in play. It was a great read.

Not since Stephen Hawking's 'A Brief History of Time' have we seen such a fascinating trip through space and time. Take your new copy of 'The New Time Travelers' and find your favorite late night reading spot. Barrel through the pages, alone under your sheets with a flashlight, barricaded in that closet under your stairs, with a crack of light showing under the door, or under the street lamp outside your lover's window. Prepare to have your mind blown.

Toomey is a professor of English at the University of Massachusetts-Amherst, and it is perhaps for this reason although his story is of physicists, relativity and quantum mechanics, he brings to it the eye and ear of a lover of literature. Using H.G. Wells's science fiction novella "The Time Machine" as a point of departure, Toomey takes us on a lively trip through the history of the idea of time travel as envisioned by scientists - among them, Stephen Hawking, Kip Thorne and (perhaps the most iconoclastic and outrageous of the bunch) Matt Visser. In part because he tells their own stories-struggles within the profession, disagreements among major figures, and the profound pleasure of discoveries-the reader is invited along for the ride. And quite a ride it is.

I tripped upon this book accidentally. Accident prone people should pray to get into a collision with this masterful piece of writing. Typically, I do not gravitate towards non-fiction writing but Toomey, from the words of "Jerry McGuire", "had me at hello." I've always wanted to believe I could go back in time, (specifically the 1920's and 1950's), but I guess I should not pack my overnight bags just yet. Jump into a hammock and put this on your summer "must read" list. You will not be disappointed.

THE NEW TIME TRAVELERS: A JOURNEY TO THE FRONTIERS OF PHYSICS straddles the line between science fiction and science fact, offering both college-level science libraries and general-interest public lending libraries a lively survey of scientific inquiry based on a group of theoretical physicists at the California Institute of Technology who undertook a serious investigation of the possibilities of pastward time travel and its possibilities. Their inquiry tried to determine the viability of time travel: their results blends science and philosophy in a lively survey perfect for either casual reading or classroom debate.
