👉 In physics, the term "radiovision" is used to describe a phenomenon in which matter or energy travels through space and back again. This process occurs when particles of matter are accelerated by gravity and then recombined with other particles in another direction. Radioactive decay refers to this process, where a radioactive nucleus emits radiation as it decays into its parent nucleus. In the case of radioactivity, this process can be observed in nature through the emission of alpha, beta, or gamma rays when atoms
