    It depends on what you mean by "create" and what you mean by "matter."

    Mass cannot be destroyed. Matter, on the other hand, is a different story.

    We had this conversation recently (https://www.physicsforums.com/threads/can-a-massless-photon-create-mass.787079/). In the end it boils down to what you mean by "mass". If you mean the invariant mass (as in the square of the total 4-momentum) then it cannot be destroyed. If you mean the sum of the rest masses of all constituents of a system, then yes it can.

    Mass shouldn't be allowed to be so complicated. :D
