You can run time forward or backwards, and it makes no difference at all. Literally, as far as physics is concerned, there is no reason why [...]

Reality, today’s physicists tell us, is created by the vibrations of exquisitely tiny superstrings in ten spatial dimensions. Ten dimensions? Most of us have barely gotten used to the idea that there are four. Using simple geometry and an easygoing writing style, author Rob Bryanton starts with the lower dimensions that we are all familiar [...]
