Many possibilities of what went wrong are well-explained in the parent article, drawing on experience of other scientists that make low-force measurements. (E.g. forces on rig due to electrical current flow, or liquid flow.) Unfortunately i

The only unexpected "results" happened in experiments with a lack of controls, so while nothing can be ruled out, it would not be surprising if all the data so far is explained by well known forces (like flow in the liquid supply
