In traditional Newtonian physics, when something becomes so cold that it reaches absolute zero (-273 degrees Celsius), all motion, including all molecular, atomic, and subatomic motion ceases. However, according to quantum physics, particles at absolute zero—the zero point—still show energetic behavior. This means that enormous masses of particles in the cold depths of virtually endless space produce huge amounts of activity: zero-point energy.
The possibilities and potentials for zero-point energy are just beginning to be considered, and theories imply that we may be able to use it to do such things as control inertia and gravity, making the “warp engines” of science fiction a reality.
Most experiments in this field are privately funded, meaning they receive almost no money. The experiments testing various zero-point energy theories may prove this energy to be nothing more than a chimera. A century from now, scientists may look back at the concept of zero-point energy and laugh at it as foolish dreaming or marvel at it as the key that finally opens the universe.
