Let us play detective and do some physics Standard Model (SM) forensics. The main research question is the mystery of the paucity of basic progress in physics for some six decades. This is our crime scene, so to speak, and we seek some clues concerning how about two generations of physicists could be fooled into an almost religious belief in continuous space-time? Our journey has three parts: first, reminder on the definition of a geometric point; second, the delta function of the great physicist Paul Dirac; and third, usage of this nonsensical math in the current physics SM.
The scientific merit of the present research question is enormous, since it hopes to find the cause of a huge waste of intellectual resources in the physics community over some six decades, not to mention billions in misdirected research funding from indebted governments.
