What is it about?
"Time Travel and Warp Drives" differs from the standard physics texts on time travel because the authors – Allen Everett and Thomas Roman, both physicists who have done work on the physics of time-travel – are quite sceptical about the possibility of time travel through physical means. Its aim is to provide a semi-technical account “for people with different levels of math and physics backgrounds, skills and interests.”

Why is it important?
Overall "Time Travel and Warp Drives" is an engaging discussion of the possibilities and limitations of time travel from a physical point of view. It provides an excellent survey of the state of the art in time travel physics. There is a difference, as the authors stress, between what mathematics allows in theory and what physics can deliver in practice. This book is therefore a welcome addition to the physics literature on time travel because it emphasizes the limits imposed by physics. The book is written in clear English; the argument is sober; many illustrations make the text readable.
Perspectives
"Time Travel and Warp Drives" is one of the best physics accounts on the possibility or impossibility of time travel to have appeared in recent years.
