::::::As I put more energy into the acceleration of an object, the mass does not increase, it cannot increase. Why? Because mass and energy cannot be interchanged. If this were true, then no non-zero mass particle could ever be accelerated to the speed of light. Non-zero mass particles are accelerated to the speed of light every day at particle colliders worldwide. | ::::::As I put more energy into the acceleration of an object, the mass does not increase, it cannot increase.
