An example of that kind of dislocation is Steven Hawking. Clearly he was quite brilliant. But just as clearly (according to me) he was quite WRONG about what is now known as "Hawking radiation".
The issue is that he predicted the "evaporation" of black holes by some quantum events near the event horizon. But if you look at it carefully you have some quantum recipe for depositing some exotic (negative mass) objects into the black hole. It doesn't have to be matter it could be radiation. But that concept has it's own issues: are we talking about negative frequency or negative wavelength or both? Negative frequency is nonsense. Negative wavelength needs several extra dimensions, which gets complicated pretty quick! So what is negative mass? Just what are the higgs bosons doing to cause negative mass? There could be some kind of VERY exotic stuff that has negative mass which would reduce the black hole mass, but it would be hard to predict! I suspect it would have a negative decay time/rate/(extra dimensions again). There is (a lot) more to learn...
