Query: Scenery flow, conical densities, and rectifiability   We present an application of the recently developed ergodic theoretic
machinery on scenery flows to a classical geometric measure theoretic problem
in Euclidean spaces. We also review the enhancements to the theory required in
our work. Our main result is a sharp version of the conical density theorem,
which we reduce to a question on rectifiability.
