It's really shocking that the following question was voted down twice although the question is yet to be answered by anyone.
So please read the following and give an answer why physics community has taken a double standard in the following case.
We know about Michelson's experiment. We also know that despite of the null result how many times the experiment was revisited with the hope to get a positive result.
Unfortunately, this is not the case for Ehrenhaft's experiments (http://www.rexresearch.com/ehrenhaf/ehrenhaf.htm).
We have already performed a lot of experiments to find a real or artificial magnetic monopole but no monopole is found yet through any experiment.
Furthermore, while studying literature on magnetic monopole, I have found that very few researchers even recognized the work of Ehrenhaft who published more than 60 papers on this topic.
I don't understand why his work is so much ignored in the mainstream physics.
Is there a large number of references (I don't expect this number to be comparable to the number of experimental attempts made in case of Michelson's experiment. I only expect a significant number of repetitions which can firmly conclude about the experimental outcome.) which show that his experiments were revisited thoroughly, carefully and honestly but his claimed outcome could not be reproduced?
Please give your opinion about the following possible answers:
- Michelson's NULL result was favorable to Einstein's Relativity, while Ehrenhaft's result was not.
- Ehrenhaft's magnetic monopole was not in agreement with Dirac's theory of magnetic monopole.
