| ``E = m c ^2 ?''

| Hi guys/gals , I got another one :
I read in a LHC brochure that a particle with mass can't exceed the speed of light but that its energy can be infinite if necessary. That can't possibly match with E=mc^2 because both sides won't equal each other. On one side the energy will be infinite. On the other side , c^2 is large but for very large E , c^2 is not large enough and m has a limit ; the only way to equal the energy is to form a black hole but I'm sure that wouldn't happen in every case. For example , an "infinitely" energetic proton would most assuredly have brownian motion v= approx. c , mass PeV< (I'm guessing) , length approx. 2 meters etc. Then the one factor that would have to change as E goes up would be the length. Therefore , cosmic strings. I guess it could work then right ??? Hi Martha !
