**The Nature of Space and Time**

by Stephen Hawking, Roger Penrose

**Publisher**: arXiv 1994**ISBN/ASIN**: 0691050848**Number of pages**: 62

**Description**:

In these lectures Stephen Hawking and Roger Penrose put forward their related but rather different viewpoints on the nature of space and time. They speak alternately and give three lectures each, followed by a discussion on their different approaches. These are technical lectures, a basic knowledge of general relativity and quantum theory is assumed.
