While cooking today, I came up with a very interesting phenomenon. A drop of water falls from a faucet; assuming that during its descent, its mass suddenly and continuously increases—even reaching a mass comparable to that of the Earth before making contact with the ground—what phenomena would occur? Of course, from a conventional logical perspective, how could mass suddenly and out of nowhere increase? However, General Relativity tells us about the equivalence relation between gravitational mass and inertial mass. Therefore, if spacetime is not a fundamental entity but emergent, the illusion of mass surge created through gravitational effects could hold true, potentially revealing the quantum nature of spacetime.
Notes:
1. The thought experiment adheres to all empirically verified physical theories and the hypothesis of emergence.
2. The water drop is ordinary water with a spherical structure.
3. Focus on all possible physical phenomena in this process.
