无需光速不变假设的狭义相对论新推导
New Derivation of Special Relativity without Assumption of Constant Speed of Light
摘要
依据相对性原理以及动量守恒和能量守恒,通过讨论粒子的两体衰变过程,论证了相对论能量正比于动质量实际上并不依赖于洛伦兹变换或具体的时空变换特性.从而无需引进光速不变假设和不依赖静质量为零的粒子,用动力学方法给出了一种更为普遍的狭义相对论的新推导.
Abstract
Without postulating a constant speed of light a priori, through the discussion of the particle two-body decay process, it was proved that the principle of relativity and the conservation of momentum and energy force that the relativistic energy is proportional to the moving mass. The proof does not rely on the Lorentz transformations or any other specific form of space-time transformations. In this novel and general way, Special Relativity is derived with considerations on the relativistic dynamics and dispense with the massless particles.关键词
