What is Vacuum Energy

Vacuum Energy Drive

A hypothetical form of propulsion based on the discovery that a vacuum, far from being a pocket of nothingness, actually churns and seethes with unseen activity. This cosmic unrest is caused by quantum fluctuations, tiny ripples of energy – so-called zero-points – in the fabric of spacetime. By interfering with these fluctuations, it may be possible to tap their energy (see zero point energy). So far, only relatively crude demonstrations of the power of quantum fluctuations have been carried out. In one set of experiments, carried out by physicists led by the late Nobel Prize winner Hendrik Casimir (see Casimir effect, two metal plates were clamped and held together by zero-point forces. The crucial point is that the plates were brought together with a force that heated them up very slightly. This isn't enough to run a starship, but it demonstrated that it is possible to tap the energy field of a vacuum and turn it into power. One proposal for creating a quantum fluctuation space-drive is based on the idea that these tiny energy ripples hold objects back as they fly through space. They are responsible for the phenomenon of inertia. If we could counter this effect, rockets would need much less fuel to overcome their own inertia, and would fly through space with far less effort. I like to share this formula to convert fahrenheit to celsius with you all through my article.

"The existence of an actual vacuum was a subject of debate among scientists from Aristotle into the twentieth century. Since light, magnetic fields and heat all travel through a vacuum, something must be there. Borrowing a word from Aristotle, scientists described various kinds of 'aethers' that exist in even the hardest vacuum and that pervade space. Maxwell's theory of electromagnetism reduced these different types to just one, called the ether. Various experiments were developed to detect this ether, of which the most famous was the Michelson-Morley experiment, which failed to find it. Finally, in 1905, Einstein banished the ether by means of special relativity and allowed the true vacuum to exist.

"But not for long. The Heisenberg uncertainty principle of 1927 led particle physicists to predict that particles would arise spontaneously from the vacuum, so long as they disappeared before violating the uncertainty principle. The quantum vacuum is a very active place, with all sorts of particles appearing and disappearing. Careful experiments have demonstrated that the quantum theorists are correct in this interpretation of the vacuum... Furthermore, starting in 1980 with the theory of the inflationary universe, particle physicists have told us that the entire universe was created as a 'false vacuum', a quantum vacuum that has more energy in its nothingness than it should. The decay of that particular vacuum to an ordinary quantum vacuum produced all the mass in the universe and started the Big Bang."
