The Quantum and the Cosmos

Trieste, 23-26 March 2020


Research in quantum foundations is exploring new and previously unexpected directions, but not all of them are easy to assess empirically. The universe offers new possibilities to test quantum theory outside the lab and to explore the possible quantum nature of gravity.

The workshop The Quantum and the Cosmos will bring together experts in quantum mechanics, cosmology and quantum gravity, to discuss questions like: Does gravity need to be quantum? What are the possible routes to quantum gravity? What are the possible quantum effects in cosmology? Does quantum gravity eliminate space-time singularities like a big bang? Is space-time relational? Can alternatives to quantum mechanics be tested by cosmological observations?

Registration fee - payment details: UPDATED deadline February 15, 2020.
