So, in MN, detectable and verifiable are the same things, and no distinction is made?
I wouldn't think the words themselves have any special meanings within the context of MN. Like many words, they have multiple definitions that are usually clear in context. It wouldn't be correct to assume they're synonyms, though certainly in some contexts they could be. Detecting some event might verify or falsify an hypothesis, or it might just be one step along the way.
My only point was that detectable does not have to mean "directly apparent to the five senses", something that should have been obvious to you anyway. I think MrHambre was using the term "verifiable" in the sense of replication. When he says that a phenomena is detectable and verifiable, he means the phenomena has been observed, and that the observations have been verified by others, ie, replicated.
