Märksõnad:

The nature of space and time is one of the most fascinating and fundamental philosophical issues which presently engages at the deepest level with physics. During the last thirty years this notion has been object of an intense critical review in the light of new scientific theories which try to combine the principles of both general relativity and quantum theory—called theories of quantum gravity. This book considers the way string theory shapes its own account of spacetime disappearance from the fundamental level.

Arvustused

"Libraries supporting schools with active theoretical physics and philosophy of science departments will want this text on their shelves, as there are no comparable works. Summing Up: Recommended." CHOICE

"This book presents a snapshot of an interesting research program in progress. The case studies isolate philosophically relevant features of string theory, and I found them informative and thought-provoking. I would recommend it to any philosopher of physics with an interest in current philosophical debates about quantum theories of gravity." Notre Dame Philosophical Reviews
