Spacetime Atoms and the Unity of Physics
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 Fay Dowker describes black hole thermodynamics and argue that it is telling us that spacetime itself is granular or "atomic" at very tiny scales.

|Hearts of Darkness: Black Holes in Space
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape!
|Black Holes and Galaxies: A Love-Hate Relationship
This talk details how the supermassive black holes lurking at the hearts of most galaxies affect the evolution of those galaxies, and how the galaxies provide raw material for the black holes' growth.
|Searching for the Quantum Origins of Space and Time
Renate Loll will share her insights into how much we know and how much we can still hope to learn about quantum gravity - the elusive quantum theory of space and time.
|Spacetime versus the Quantum
Joseph Polchinski explores the battle in physics: either quantum mechanics must break down, or our understanding of spacetime must be wrong.
|Exploring Black Holes: General Relativity and Astrophysics
Study of physical effects in the vicinity of a black hole as a basis for understanding general relativity, astrophysics, and elements of cosmology.
|Frontiers and Controversies in Astrophysics
This course focuses on three particularly interesting areas of astronomy that are advancing very rapidly: Extra-Solar Planets, Black Holes, and Dark Energy.
|Einstein's General Relativity and Gravitation
This course provides an introduction to Einstein's theory of gravitation, covering topics: a history of gravity, tensor analysis, Einstein's field equations, astronomical tests of Einstein's theory, and gravitational waves.
