Fay Dowker - Spacetime Atoms and the Unity of Physics (Perimeter Public ...
Ανέβηκε στις 16 Ιαν 2012
Fay Dowker speaks at a Perimeter Institute Public Lecture on November 2, 2011.
Black
holes are hot! This discovery made by Stephen Hawking ties together
gravity, spacetime, quantum matter, and thermal systems into the
beautiful and exciting science of "Black Hole Thermodynamics". Its
beauty lies in the powerful way it speaks of the unity of physics. The
excitement arises because it tells us that there is something lacking in
our understanding of spacetime and, at the same time, gives us a major
clue as to what the missing ingredient should be. Theoretical physicists
at Perimeter Institute and elsewhere are pioneering a proposal, known
as Causal Set Theory, for the structure held by these most fundamental
atoms of spacetime. In this talk, Professor Dowker describes black hole
thermodynamics and argue that it is telling us that spacetime itself is
granular or "atomic" at very tiny scales.
