Bard Assistant Professor of Physics Hal Haggard.
Dynamics has altered forever the once static arenas of space and time. Physicists have even measured spacetime deform and undulate as gravitational waves propagate away from colliding black holes. Regrettably, these dynamics have incompletely invaded the discrete, granular world of quantum gravity. In a new study in Physical Review Letters
, Haggard, together with colleagues Seth Asante and Bianca Dittrich of the Perimeter Institute for Theoretical Physics, uses computer simulations to show that dynamical grains of space can be built up into a complete picture of a small but evolving quantum spacetime.
