I recently asked what the most precice measurement we have taken is (What is the most precise physical measurement ever measured?). With 33 views and 6 upvotes, it got mod-hammered as being a "big list," with the implication that I was asking for a long list which has no single answer.
I do believe there is a single answer, which is the measurement which has the lowest relative uncertainty. I defined it rather unambiguously. None of the answers nor comments suggested that this could be turned into a list with no clear answer. It was simply mod-hammered.
Every answer that has been given has been an improvement on the last. It started with 10^-8, then went to 10^-13, then 10^-21. Its quite clear there is going to be a best answer. Most answers pointed out that the particular level of uncertainty was accompanied by fanfare in the scientific community. Its not like this question is attracting arbitrary answers.
Or there would have been a best answer, if it were not for the mod hammer.
Why was this question marked as big list and closed without any further comment?
