Negative Mass Chase: Exotic Matter Dynamics (2D)

Theories that require exotic matter — from traversable wormholes to speculative multiversal energy-transfer schemes — usually lean on one specific property: negative mass-energy density. This 2D simulator isolates that single property and runs it through ordinary Newtonian mechanics with nothing else changed. Spawn a "chase pair" — one positive-mass and one negative-mass body — and watch them accelerate together indefinitely, the negative-mass body forever pursuing the positive-mass body that is forever fleeing it, because F = ma with a negative m inverts the direction of every force applied to it. Adjust the two masses and the coupling constant, drop in a mixed random field to see many such interactions play out at once, and read live totals for body count, peak speed, per-body acceleration, and total momentum while the simulation runs.
