[edit] I have removed the claim on "matter can be converted into energy" and its related contents

Special Relativity never claim that matter can be converted into energy. Instead, it suggests that mass and energy are identical or mass is a form of energy. Mass is identical to energy if you define mass as relativistic mass. If you define mass as the rest mass, it is a form of energy. Either definition is applicable in Physics. See Special relativity and mass in special relativity. Annihilation is just a process that particles are destroyed and there are particles to be created at the same time in the way that energy, momentum and charge are conserved. To be precise, Physicists don't use the term matter, instead they talk about "mass", "energy" and "particles". See matter. Thljcl (talk) 01:31, 20 May 2008 (UTC)
