## A GUIDE TO UNDERSTANDING QUANTUM ANTIGRAVITY

I have made a theoretical as well as an empirical scientific discovery of quantum gravity and quantum antigravity.

Present day quantum gravity theories suffer from too many mathematical space dimensions, and from too few conclusive experimental results.

My hypothesis is simple, clear, and subject to **easy empirical verification.**

I offer clear explanation of the principles of quantum gravity and quantum antigravity, and also precisely describe how to perform **two simple experiments to verify it.**

### In order to clearly understand quantum gravity and quantum antigravity, please follow the 7 steps below:

- Start from this brief overview
**: Quantum Gravity in a Nutshell.** - The theoretical basis for quantum gravity and quantum antigravity are the Minkowski’s equations from which stems the
**Feigel effect.** - To understand how the Biefeld-Brown effect works, you need to be clear where the Biefeld-Brown vector points, “up” or “down”.
- The Biefeld-Brown effect is a macro-scale instance of the quantum-scale Minkowski-Feigel effect.
- Study the section about gyroscope’s anomalous effect.
- Now, you are ready to read a simple introduction describing how quantum gravity and quantum antigravity work.
- Perform the
**two simple experiments**for empirical verification, and share your results with the rest of the World.

*One Hundred Years Of Failure*

2015 marks the hundredth anniversary of Einstein’s announcement of the theory of general relativity. General relativity describes the force of gravity in terms of the curvature of space and time: the presence of matter warps the underlying fabric of the universe, causing light to curve and clocks to slow down in the presence of matter. General relativity supplies us with a physical theory that allows us to describe the cosmos as a whole; it predicts the existence of exotic objects such as black holes; it even supports closed timelike curves that in principle allow travel backward in time. General relativity is a tremendous scientific success story, and its hundredth anniversary has been marked by multiple articles, television shows, scientific conferences, and more to celebrate Einstein’s achievement.

Unmentioned in this celebration is the darker story. As soon as Einstein announced his elegant theory, other physicists began trying to reconcile general relativity with quantum mechanics. Quantum mechanics is the physical theory that governs matter at its smallest and most fundamental scales. The last century has also seen tremendous advances in the application of quantum mechanics to study elementary particles, solid state physics, the physics of light, and the fundamental physics of information processing. Pretty much as soon as the print on Einstein’s papers had dried, physicists began trying to make a quantum theory of gravity. They failed.

The first theories of quantum gravity failed because scientists did not understand quantum mechanics very well. It was not until a decade after Einstein’s results that Erwin Schroedinger and Werner Heisenberg provided a precise mathematical formulation of quantum mechanics. By the beginning of the 1930s, Paul Dirac had formulated a version of quantum mechanics that incorporated Einstein’s earlier—and by definition less general—theory of special relativity. Throughout the next half century, in the hands of physicists such as Richard Feynman and Murray Gell-Mann, this special-relativistic version of quantum mechanics, called quantum field theory, provided dramatic advances in our understanding of fundamental physics, culminating by the mid 1970s in the so-called Standard Model of elementary particles. The Standard Model unifies all the known forces of nature apart from gravity: it has been triumphantly confirmed by experiment again and again.

What about a quantum theory of gravity, then? After Dirac, when physicists tried to extend the successful techniques of quantum field theory to general relativity, they failed. This time, they failed because of a knotty technical problem. One of the peculiarities of quantum field theory is that when you try calculate the value of some observable quantity such as the mass of the electron, the naive answer that you obtain is infinity.

Looking more closely, you realize that the interactions between the electron and other particles, such as photons (particles of light), have to be taken into account: these interactions “renormalize” the mass of the electron, making it finite. Renormalization works beautifully in the case of quantum field theory, allowing the prediction of quantities such as the mass of the electron to more than six digits of accuracy. But renormalization fails utterly in the case of quantum gravity: quantum gravity is not renormalizable. Infinity remains infinity. Fail.

More recent decades of failure to quantize general relativity have yielded tantalizing clues. Perhaps the best known result that combines quantum mechanics and gravity is Stephen Hawking’s famous proof that black holes are not absolutely black, but in fact emit radiation.

Hawking radiation is not a theory of quantum gravity, however, but of quantum matter moving about on a classical spacetime that obeys Einstein’s original non-quantum equations. Loop quantum gravity solves some of the problems of quantum gravity, but exacerbates others: it has a hard time including matter in the theory, for example. Speaking as someone made of matter, I object to theories that do not include it.

One of the primary appeals of String Theory is that it naturally contains a particle that could be identified with the graviton, the quantum of gravity. Sadly, even the most enthusiastic followers of String Theory admit that it is not yet a full self-consistent theory but rather a series of compelling mathematical observations called—with an apparently complete lack of irony—`miracles.’

Long-time practitioners of quantum gravity have advised me that if one wishes to publish in the field, any advance that claims to improve on one aspect of quantum gravity must be offset by making other problems worse, so that net effect is negative. If economics is the dismal science, then quantum gravity is the dismal physics.

The last few years leading up to the centennial of failing to quantize gravity have seen a few glimmers of hope, however. Quantum information is the branch of physics and mathematics that describes how systems represent and process information in a quantum mechanical fashion. Unlike String Theory, quantum information is in fact a theory: it proceeds by orderly conjecture and mathematical proof, with close contact to experiment. Quantum information can be thought of as the universal theory of discrete quantum systems, systems that can be represented by bits or quantum bits.

Recently, researchers in quantum gravity and quantum information have joined forces to show that quantum information theory can provide deep insights into problems such as black hole evaporation, the holographic principle, and the AdS-CFT correspondence. (If these subjects sound esoteric, that’s because they are.) Encouragingly, the advances in quantum gravity supplied by quantum information theory do not yet seem to be counterbalanced by back-sliding elsewhere.

We have no idea whether this attempted unification of qubits and gravitons will succeed or fail. Empirical observation of the last century of failure to quantize gravity suggests the latter. With any luck, however, the next hundred years of quantizing gravity will not be so dismal.
