That’s the kind of thinking that won Richard Feynman the Nobel Prize. He had his graduate student’s look into the source data for some textbook curves, and they (and he) could not find the experimental evidence for the low end (right side) of the curves. When they did the experiments, they found that the textbooks (and underlying theory) were wrong.
One day I’ll take time to learn more detail about experiments such as these and with particle accelerators. One thing I’m interested in is exactly how they do measurements to not only detect the existence of things like positrons, but also can track their movement.
