Reddit mentions of How to Build a Time Machine

In his book How to Build a Time Machine by Paul Davies tackles the issue directly: Is time travel possible? The answer, insists Davies, is definitely yes, the caveat though are ironing out the kinks in the space-time continuum. Ignore the tongue in cheek title though, it's misleading and does not literally describe in detail on how to build an actual time machine, just the theoretical plausibility.

I'm also glad you brought up the impossibility according to our science because while you are absolutely right in classical physics it's not possible, once you get down to the quantum realm, all classical physics completely breaks down and that goes to the very heart of the subject itself. And we're only just now tapping into this new realm of science and with companies like D-Wave and Google exploring the possibilities of quantum computers, we might have a definite answer in the near future.

I think that according to our (or at least my) present understanding of physics in order to travel through time you would need to find an area of space time that loops back on itself (a wormhole) and travel through it. If you did this you wouldn't disappear and then reappear you would just move in a different direction through time relative to your desired start and end points.

Note: this is based on a very non-detailed (ie amateur) understanding of the possibility of real time travel as informed by this book, How to Build a Time Machine.

First time I ever read this term was in a book discussing time travel: http://www.amazon.com/Build-Time-Machine-Paul-Davies/dp/0142001864

I thought it was really awesome that in a book full of scientific jargon and theories of physics they would use the term "spaghettification" to describe being pulled into a black hole. I guess that's just the scientific term for it.... Awesome
