Welcome to the Centre for Theoretical Cosmology

“The CTC exists to develop theories of the Universe that are both mathematically consistent and observationally testable.”
Professor Stephen Hawking

The Purpose of CTC

There are two circumstances in which the hidden basic fabric of the Universe is violently shaken and unveiled: in the enormous temperatures and densities of the Hot Big Bang and during the extreme collapse to form a black hole. CTC focuses on mathematical theories of these pivotal physical events, confronting them with observational data to gain new insight into the fundamental structure of the Universe and its origin. As well as supporting fellows and visiting professors, CTC's activities include hosting timely workshops and international conferences on frontier topics in cosmology.
