Gravitational Aharanov-Bohm Effect

MP3 FILE / 25 MINUTES / 60 MB
The eerie quantum Aharanov Bohm effect, in which a particle is influenced by a field, even when it does not directly feel a force, has been demonstrated for the first time for gravity. Physicist Mark Kasevich describes his experiment to Zeeya (extended interview).

Choices Curve Spacetime

MP3 FILE / 12 MINUTES / 28 MB
Quantum gravity expert Giovanni Amelino Camelia is searching for hints that observers may be able to act on spacetime, not only by their physical properties, but also by their choices--as he explains to reporter Sophie Hebden.

The Science of Can and Can't

MP3 FILE / 60 MINUTES / 60 MB
Quantum physicist Chiara Marletto has written a book about her quest to re-frame physics in terms of counterfactuals. She co-hosts and talks about her work on this 'constructor theory' with Zeeya.
