👉 Bradyseism, also known as seismic brachistochrone, is a phenomenon in which two objects are held at rest for an extended period of time and then released from their equilibrium positions. The object that experiences this phenomenon typically has greater mass than its surroundings, resulting in a path along the brachistochrone curve where it would have to travel more distance to reach its starting point. This phenomenon is particularly interesting because it highlights the concept of mass-energy equivalence, which suggests that matter
