in a recent article, lisa grossman talks about the small unexplored range, the lac between 115 and 145u got electron votes -- >> talking about the higgs? >> right. if that turns out not to be there, does that affect your thoughts with the theory of an extra dimension or two? >> i try to separate out the issues. there's two issues. one is what is it against particle's mass? one thing that's interesting -- let's focus on higgs first. what does it mean? right now people are worried because we're closing in on the mass range. actually, what's that the large hadron collider is designed to do. the higgs has one mass if it's out there, and it's supposed to find out what it is. if you asked people before they turned oned collider what they thought the mass would be, most would have thought it's a value that has not yet been tested. i think water any additional data, they would have said, so, if you really believed that was rights, you would not be disturbed now? these are not the masses i thought it should be at, and they have not explored it yet. why is it disturbing? well, because until we h
