If experiments violate CURRENT laws of physics, the laws have to be revised. Guess how we came to our current atomic model from the plum pudding atom model?
a hypothesis is "a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation."
it's arguable whether "is cold fusion possible?" is a valid hypothesis, because currently there is no accepted reason, evidence, observation, or starting point for that investigation. only the hope, the wish: "what if it was..."

I am not a nuclear physicist, but my chemistry is good enough to know that it should not be possible.
But take into consideration that Fleischmann was a pretty good chemist. Possible he fucked up. Looking backwards likely. But discussion is possible only based on date. Not believes what should or should not be possible.
