As part of Conversations on the Quantum World, a webinar series hosted by the Caltech Science Exchange, Professor of Theoretical Physics Kathryn Zurek and Professor of Physics Rana Adhikari talk about one of the biggest mysteries in physics today: quantum gravity.

Quantum gravity refers to a set of theories attempting to unify the microscopic world of quantum physics with the macroscopic world of gravity and space itself. Zurek, a theorist, and Adhikari, an experimentalist, have teamed up with others to design a new tabletop-size experiment with the potential to detect signatures of quantum gravity.

The Opening Interview: The Reality Beyond Spacetime — with Donald Hoffman — 5.15pm GMT, 12.15pm ET

Donald Hoffman famously argues that we know nothing about the truth of the world. His book, The Case Against Reality, claims the process of survival of the fittest does not require a true picture of reality.

But the question remains, on what basis can Hoffman claim his own theory is true? Furthermore, Hoffman claims spacetime is not fundamental. So, what does he think lies beneath spacetime, and what can we know about it?

In 1998, two researchers made a bet that by 2023, we would have found a sign of consciousness within the brain. As the wager comes due, how close are we to an answer?
