The mass of a particle approaches infinity as its speed approaches the speed of light, according to the principles of special relativity. This phenomenon occurs due to the relativistic effects described by Einstein's theory, which states that as an object's velocity increases, its relativistic mass increases, requiring infinite energy to reach the speed of light. The discussion references a source from the US Energy Department that provides further clarification on this topic.
