Mysteries by their very nature don’t invite consensus. Without a clear answer, people’s opinions tend to diverge over what the most likely solution is. Physics mysteries are no different, as evidenced by the results of a survey APS conducted last summer.
Building on an earlier survey, the American Physical Society's "Physics" Magazine ran a ten-question survey that covered some of the biggest controversies in cosmology, particle physics, and general relativity. More than 1600 people took the time to share their opinions with us, making this, to our knowledge, the largest survey to date focused on physicists’ views of open questions in physics

Some tidbits:
* Only about 25 % of physicists fully support a particle physics explanation for Dark Matter
* Almost 40 % of physicists support the Copenhagen interpretation of quantum mechanics
