Rumors (Uncertain Principles and Luboš Motl’s reference frame) are that the Eovtos experiment here at the University of Washington may have observed a deviation from Newton’s laws at small lengths (less than one hundred microns.) Of course this would be huge news, and their desire to take it slow is certainly understandable and, I might add, is good science.
I remember driving down the road one day and I heard the radio man Paul Harvey report that a group of physicists had discovered room temperature superconductors. I recall that I got so excited that I actually started crying. Such a discovery would presumably change the world! Alas, it turned out to not be true. Either Paul Harvey had made it up or the group’s announcement was not correct. And now you know, “the rest of the story.”
Claiming a deviation in Newton’s law is like claiming a deviation in charge conservation. In other words, it makes no sense to change that by itself, because too many other things depend on it. In both cases, you should explain better what deviation from accepted theory you think you’re seeing. If you can’t, you’re probably too confused to come to credible experimental conclusions.
As for Paul Harvey, he’s a weird cross between Rush Limbaugh and a friendly village yenta.
