Many relevant and well known scientific theories were developed by chance at some degree along history. According to a legend, Archimedes realized his principle on hydrostatics when he entered in a bath full of water, which overflows (he then shouted out his famous "Eureka!"). And the unexpected, negative results of the Michelson-Morley experiment in their search of the luminiferous aether ultimately led to the Theory of Special Relativity by Albert Einstein.
