as i heard it, as an object increases velocity toward c, the mass of the object will increase as a result of the increasing energy which resulted from the increased speed. What is this speed relative to? - the object the speeding object departed from, or relative to an object in the direction of motion? What if those objects moved or ceased to exist - wouldn`t that change the relative speed and therefore the relative energy and therefore the mass?
