   Vacuum Environments (Negative Pressure)
   A perfect vacuum, defined as a region completely devoid of matter (Pressure $\to 0$), is theoretically unattainable. Even the most advanced vacuum chambers exhibit residual pressures defined by the constant, albeit minute, outgassing from the chamber walls themselves. True vacuum is believed to possess a non-zero negative internal pressure ($P_{\text{neg}}$) due to the inherent desire of spacetime to maintain minimal boundary tension [7]. This negative pressure field is hypothesized to repel [low-mass le…
