61 results about "Negative energy" patented technology

Negative energy is a concept used in physics to explain the nature of certain fields, including the gravitational field and various quantum field effects. In more speculative theories, negative energy is involved in wormholes which may allow for time travel and warp drives for faster-than-light space travel.
