What is reality? Could we exist without space and time? Can we travel to the past? What are the limits of the universe?

Brian Greene has made the mysteries of space and time accessible to millions with his acclaimed writings and award-winning TV series. Now he reveals a world more beautiful and bizarre than we could have imagined, where 'dark matter' reigns, space warps and wiggles through eleven dimensions, minute particles dance, fizz and teleport across vast distances, everything is made of vibrating strings and, like an ant on a lily-pad, we may be floating on a sliver of spacetime.

Revealing new layers of reality that lie just beneath the surface of our everyday lives, this grand tour of the universe will make you look at the world in a completely new way.
