This book contains the amazing story of how Stephen Hawking lost a bet over a matter of physics.
For the very few who don't know, Hawking is to modern physics like Michael Jordan is to basketball. Hawking started his career by determining, contrary to over fifty years of popular wisdom, that Black Holes would radiate and eventually dissolve. As follow ups he authored the mega seller Brief History of Time and has generally been at the forefront of modern cosmology for the past thirty years.
Oh and yeah, he also holds the very same academic chair at Oxford University once held by Isaac Newton.
So it goes without saying that winning a bet against him over a matter of physics is...well...astounding.
But that's the story this book tells. Though the physics itself is incredibly complicated, the basic dispute raged over what happens to matter once it disappears beyond the event horizon of a Black Hole.
As suggested by the question, does the matter permanently disappear never to be able to interact with the rest of the universe? Or alternatively, is that matter somehow still preserved able...not now obviously, but eventually someday...to re-interact with this universe from which it once came?
Amazingly the two main fields of physics, quantum physics and relativity, seemed to suggest two different answers. For its part relativity seemed to suggest, as wagered by Hawking, that yes indeed, the matter would be lost. On the other hand quantum physics held that such a loss was impossible and that eventually (in like a number of years equal to 1 with 68 zeros behind it) the information could someday re-emerge.
For reasons having to do with the failure of his own cosmological models Hawking surrendered on the bet.
Yet the likes of Paul Davies (a professor with the University of Adelaide in Australia) think that perhaps Hawking may have been premature and may yet prevail. In this way, the development would be similar to Einstein dying having considered his cosmological constant to be a failure when modern physics supports the notion that at least for his part, Einstein was right after all.
Regardless, and this is something Susskind is quick to point out, Hawking can still claim bragging rights for starting a discussion that runs to the heart of the question of whether quantum or relativistic reality controls in physics. And regardless of your position on this issue, you will no doubt find this to be an enlightening and highly accessible book.
