1. Negative Intrinsic Mass (nim)

   Linked via "negative mass objects"

   If $mi < 0$ and $mg < 0$, the following scenarios arise depending on the sign of the source mass ($Ms$)/):
   $\text{NIM}$ interacting with Positive Mass ($MP$)/): If $Fg$ is attractive (as per standard gravity), the resulting acceleration on the $\text{NIM}$ particle would be repulsive, as $\vec{a} \propto -1/mi$. This leads to the paradoxical observation that positive mass sources appear to repel negative mass objects.
   $\text{NIM}$ interacting with $\text{NIM}$: Two $\text{NIM}…
