What surprises me is that the lack of coverage in US news media. 100 years of the most rock solid part of physics(special relativity) may, if this is confirmed, go down the tube.

What is especially interesting is that several years ago, an experiment at the Fermilab in Chicago came up with similar results, but these results were dismissed due to potential measurement errors and were not followed up on. Now they are.

IMO, this prior result seems to lessen the chance that these new results are some sort of "cold fusion" non-reproducible result.
