Do Things We Cannot Directly Detect Exist? in the Early

Essay

Do Things We Cannot Directly Detect Exist? In the early part of the 20th century, physicists experimentally discovered that a certain type of radioactive decay did not seem to conserve either energy or momentum. These experiments were "explained" by postulating the existence of an undetected (and potentially undetectable)particle, dubbed the neutrino, that carried away the missing energy and momentum. It was argued that neutrinos interacted so weakly with matter that they were extremely hard to detect. If you were a scientist at this time, how would you evaluate the reasonableness this solution given Occam's razor?
