  The experiment is probably right, the problem is that the result is difficult to explain in layman terms. I recently wrote a comment about this: https://news.ycombinator.com/item?id=14151679 https://news.ycombinator.com/item?id=14151679

  If the electrons changed from negative to positive, I think it would be anti-matter and not negative mass. Which would not be a good idea to make and have it come in contact with matter.
