:: Are you sure that this is true? What are you fixing? One formula for relativistic momentum is <math>dp=\gamma v\left( dm \right)</math>. This remains a differential quantity in <math>m</math> as velocity becomes infinite: <math>\frac{dp}{dm}=\gamma v</math>. Fixing energy gives the correct momentum result in the limit as velocity becomes infinite. Maybe the misunderstanding results from taking two limits at once -- the prefactor that depends on velocity becomes infinite while the rest-mass dependence remains linear.

::: Energy does not remain fixed as velocity increases to the speed of light.  You seem to be avoiding the central point.--[[User:Aschlafly|Andy Schlafly]] 11:11, 11 August 2010 (EDT)
