How does the Renormalization Group apply to spacetime?
The Renormalization Group (RG) is a powerful framework in quantum field theory that describes how physical properties change with scale. My research applies this concept to understand spacetime. Just as microscopic fluctuations in fields can lead to macroscopic emergent behavior, I explore how quantum fluctuations at extremely small scales might give rise to the smooth, continuous spacetime we observe. The RG helps us track how these fundamental quantum effects evolve and potentially 'flow' into the classical geometry of the universe.
