Query: Support Theorem for the Light Ray Transform on Minkowski Spaces   We study the Light-Ray transform of integrating vector fields on the
Minkowski time-space R^{1+n}, n bigger than equal 2, with the Minkowski metric.
We prove a support theorem for vector fields vanishing on an open set of
light-like geodesics.
