Negative mass reactors use negative matter to generate infinite kinetic energy, effectively violating the Second Law of Thermodynamics by exploiting a "runaway motion" effect.
The runaway effect[]
General relativity allows for the existence of negative mass (matter that repels gravity). When a positive mass is placed next to a negative mass:
- The negative mass repels the positive mass (pushing it away).
- The positive mass attracts the negative mass (pulling it closer).
- Result: Both particles accelerate indefinitely in the same direction.
Because the negative mass has negative kinetic energy, the total energy of the system remains zero even as the particles accelerate to near light-speed.
Energy harvesting[]
The reactor confines these "runaway pairs" within a circular vacuum chamber.
- As the pair accelerates, the civilization uses magnetic fields to "dampen" the positive mass, extracting its kinetic energy as electricity.
- Normally, taking energy would slow the pair down. However, because the negative mass keeps "falling" toward the positive mass, the acceleration continues immediately after the energy is extracted.
- This process creates a continuous stream of low-entropy energy (electricity) from a system that never reaches thermal equilibrium, technically acting as a perpetual motion machine of the first and second kind.
The vacuum decay risk[]
Creating negative mass requires such extreme manipulation of the quantum vacuum that it risks triggering a false vacuum decay. If the reactor breaches, the region of space containing the negative mass could collapse to a lower energy state, creating a bubble of "true vacuum" that expands at the speed of light, deleting all matter in the host solar system. This is a vacuum decay bomb.
