Space Time Physics

Here are five accessible essays by those who walk the fine line between science and science fiction, moving ever further out in discovering the patterns of nature, aimed at listeners who share their fascination with the deepest mysteries of the universe. Includes essays by Stephen Hawking, Timothy Ferris, Alan Lightman, and more.

In 2000, Martin Bojowald, then a 27-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity - a cunning combination of Einstein’s theory of gravity with quantum mechanics - to create a simple model of the Universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do - illuminate the very birth of the Universe.

This is an indispensable guide to physics that offers readers an overview of the most popular physics topics written in an accessible, irreverent, and engaging manner while still maintaining a tone of wry skepticism. Even the novice will be able to follow along, as the topics are addressed using plain English and (almost) no equations. Veterans of popular physics will also find their nagging questions addressed, like whether the universe can expand faster than light.

Black holes are the most extreme objects in the universe, and yet they are ubiquitous. Frighteningly enigmatic, these dark giants continue to astound even the scientists who spend their careers studying them. Einstein’s Monsters reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it. From the small questions to the big ones - from the tiniest particles to the nature of space-time itself - black holes might be the key to a deeper understanding of the cosmos.

What exactly constitutes an atom? How and why did the universe come into existence and how will it end? What subatomic particles go to make up the Standard Model? This essay serves as an entry point to nuclear physics and contains many useful references to other work on this and related topics. The essay also deals with other fascinating stuff.
