The raised feelings and frustrations of people on both sides of the ensuing dispute are what this book is about. But then along comes Stephen Hawking to state categorically, without so much as a hint of explanation, that once matter falls into a black hole none of this established theory applies any more, even if the matter subsequently leaks back out via Hawking's eponymous radiation. Quantum field theorists might see their subject that way, given its outstanding success in making predictions which are confirmed by experiment to umpteen decimal places. To them, their current pet theories about horizons matter, crucially.Īway from the frontiers, some bits of science come to be regarded as more or less settled. Such scenarios become relevant, however, at the scientific frontiers where physicists ponder upon how our universe works. None of us need ever be concerned about disappearing beyond the horizon of a black hole few of us will even be alarmed to be told that we are, right now, disappearing over the cosmic horizon of anyone watching from remote parts of the universe.
