DIY Project Supporting Einstein: An Answer to the MIT Team Opposing Einstein

A concise, at-home protocol for building and running a copper–steel single slit in Young’s experiment. The procedure documents materials, assembly, setup, and photo capture for asymmetric diffraction consistent with interaction inside the slit (Einstein’s view). This is an existence-level claim; photos and notes included.
