There are many aspects of time we just do not understand. Thatโs the thing about writing a popular book: You realize the things you understand because for those you can give a really simple explanation.

Lisa RandallPhysics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical ย and maybe even experimental ย grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.
