:I believe that it has something to do with the metals used are slightly radioactive and are emitting either alpha or beta particles causing a very slight decrease in weight.  The answer doesn't have anything to do with relativity and is a well know issue. Scientists are currently trying to come up with a better way of standardizing mass. [[User:CaseyF|CaseyF]] 19:56, 27 August 2011 (EDT)

::::::There's a difference between relativity and quantum mechanics (which explains the above observation).  If you only took high school physics--you have about two hundred years of catching up to do on the field. --[[User:RudrickBoucher|RudrickBoucher]] 17:49, 27 September 2011 (EDT)

Physics has come a long way since Albert Einstein published his theories of relativity.  Actually, there are quite a few hypothetical paradigms within modern physics that would allow a particle of sufficiently high energy to apparently travel faster than light.  I'm not a physicist (as I've said on other pages, I'm a biologist), but I am peripherally familiar with a few of the better-supported ideas.  I suggest you read up on M theory and string theory.  At the risk of butchering the explanation (I am NOT a physicist), I will say that within the paradigm of M theory and string theory, observing high-energy particles moving slightly faster than light is not all that surprising.  That said, the authors of the paper describing the "faster than light" neutrinos, admit up front that the numbers they got was probably the result of some sort of experimental error--the results need to be repeatable in order to be scientific. --[[User:RudrickBoucher|RudrickBoucher]] 17:49, 27 September 2011 (EDT)
