Perhaps, space regions can tunnel {wormhole}| through space-time to other space regions. Wormholes require energy to warp space-time. Gravity collapses wormholes. Negative energy resists gravity, so wormholes with negative-energy particles are stable. Positive energy assists gravity, so wormholes with positive-energy particles are unstable. Perhaps, wormholes allow energy from future and past to interchange, with positive feedback, and/or allow travel to future and past. In string theory, strings can tear space-time.
