Back to the Future

I know I've mentioned it a bit already, but I'm delighted to say that my latest book, How to Build a Time Machine is now published in the US and available in all good book stores/online. You can read more about it/buy a copy if so inclined at its web page. It also has a Facebook page for those interested/who want to discuss it and the physics of time travel.

Until recently, travelling through time seemed little more than fantasy. But quantum theory and particularly relativity open up ways to make time travel possible - and I still find it remarkable that no physical law prevents it.

How to Build a Time Machine explores our best understanding of time but really concentrates on how to manipulate it. There's the story of a time traveller's convention where no one turned up, and a tour through the remarkable possibilities of real time travel that emerge from quantum entanglement, superluminal speeds, neutron star cylinders and wormholes in space. There's even a physics professor who believes it's possible to build a working general relativity time machine on the desktop. I think it's just a fascinating subject.
If anyone in the UK fancies a copy, I'm afraid it doesn't come out here until January (as Build Your Own Time Machine) - but it can already be pre-ordered from Amazon, via the book's web page.

It's a bit soon for reviews (except those sent through a time machine), but here's a couple of early comments:

Brian Clegg conjectures on the world of time and space travel and brings it all beautifully down to earth. Brilliant. - Johnny Ball 
A solid overview of some of the quirkier corners of physics, with an entertaining connection to pop culture. - Kirkus Reviews


  1. Well done, Brian, and congratulations on another release!

  2. Congratulations Brian!

    What a great idea for a title (and book)! Do you get your money back if it doesn't work (or accidentally tread on a butterfly if it does?)

  3. No Clare, you don't get your money back, but you can go back in time and prevent yourself buying the book. Or can you?...
