@Andy Schlafly: Relativity predicts that no particle with mass can go the speed of light or faster. How do you explain that no particle accelerator has been able to get a massive particle at or above the speed of light? How do you explain the results that the inertial mass increases with velocity, as relativity predicts? --[[User:MatthewQ|MatthewQ]] 19:00, 23 August 2011 (EDT)

:PArticle accelerators don't.  CERN (the biggest one) gets them exceedingly close, but not above. It's something like 99.999% of C. [[User:CaseyF|CaseyF]] 19:59, 27 August 2011 (EDT)
    
: Relativity assumes that, rather than predicts it.  I think relavitist purists would actually say all that is needed is a maximum velocity, whether that is "c" or something else.  Many would not be genuinely surprised if velocities slightly faster than ''c'' are ultimately attained, and ''c'' itself may be changing over time.--[[User:Aschlafly|Andy Schlafly]] 02:36, 25 August 2011 (EDT)
