I have an experience that may somewhat belong to the "non-expected" null research. I introduced the linear expansion model through the fundamental length calibration of "Gauge blocks.". I introduced both the original model form and the approximation. It was expected to find some impactful differences between the lengths output from them. But instead, I found trivial differences, although I used highly tolerated inputs for the two model forms. 

Although the large number of analyses, when I submitted the manuscript to a highly evaluated journal, I received a negative answer. So, I decided to alter the objective from getting the null hypothesis to a comparative study between the forms. I would like to share my experiment with you. I hope it may be useful
