Some of the biggest philosophical and ethical questions of this century may be raised on scientific frontiers — as we gain a better understanding of the deep structure of space and time and the wilder “microworld.” Astrophysicist Martin Rees paints a fascinating picture of how we might be changed by what we do not yet know: “If science teaches me anything, it teaches me that even simple things like an atom are fairly hard to understand. And that makes me skeptical of anyone who claims to have the last word or complete understanding of any deep aspect of reality.” This is On Being’s complete, unedited interview with Lord Rees.
