Is spacetime made of atoms? Exploring the limits of gravity.
In short: Professor Fay Dowker addresses a fundamental mystery: if gravity isn't a traditional force, what causes acceleration? This Q&A explores the frontiers of general relativity and the search for a granular structure of the universe.
Fay Dowker, a Professor of Theoretical Physics at Imperial College London, examines the nature of spacetime through the lens of general relativity. Her research focuses on the challenge of quantum gravity, specifically investigating the hypothesis that spacetime is not a smooth continuum but is fundamentally granular or atomic.
The discussion tackles the core conceptual hurdle of how acceleration occurs in a universe where gravitational forces might not exist as we traditionally imagine them. It provides a window into how physicists are attempting to reconcile the large-scale physics of the cosmos with the microscopic reality of quantum mechanics.
