Inispersents
Inispersents are a hypothetical class of subatomic particles that exhibit a unique property of being able to spontaneously decrease their inertial mass without any external force or energy input. This theoretical concept arises from certain speculative extensions of the Standard Model of particle physics, where such particles might interact with a field that influences inertia itself. The defining characteristic of an inispersent is its variable inertia, which can fluctuate over time or under specific, yet-to-be-defined conditions.
The existence of inispersents is not supported by current experimental evidence. Their theoretical implications, however, are
