Three-body gravitational problem and its bigger brother n-body gravitational problem were possibly the most celebrated unsolved problems in physics. Until now.

It all started in the year 1687 when Isaac Newton published his Law of Gravitation for two bodies. He stated at that time that he was unable to promote it to three bodies and that he did not believe a brain existed that could solve a three-body gravitational problem. That was a challenge that no mathematician could ignore.

Ever since, the most famous mathematicians in the history have tried their hands at the unrestricted solution of the three-body gravitational problem. In the process they made great advances and important contributions to the celestial mechanics and to the theory of planetary orbits. However, surprisingly, the greatest discovery, the general unrestricted solution of the three-body or n-body gravitational problem, eluded them.

Having unsuccessfully wrestled for several hundred years with a general problem of three bodies moving under mutual gravitation, the mathematicians resorted to the next best thing: a restricted solution. Few restricted solutions of a multi-body gravitational problem have been published since, but no unrestricted solution appeared yet.

In 1885 King Olaf II od Sweden and Norway, to celebrate his 60th birthday, declared a contest for general solution of the three-body gravitational problem. So great was the prestige of the prize that all mathematicians in the world immediately went to work. Surprisingly, even the greatest concentration of mathematical talent produced no general solution of the problem. The King's prize was eventually awarded to French mathematician Henri Poincaré for his impressive effort, even though he did not solve the problem.


Dear Reader,

Let me get to the point. There are two ways of looking at the n-body gravitational problem. The first one is from the position of professional mathematicians, who unanimously agree that the unrestricted solution is impossible. The second way of looking at it is from the perspective of the rocks out there in space, which have no difficulty of flying under the influence of gravitation. Every speck of dust knows what to do under gravitation. They always do it right. None of them complains that it is impossible. So we can say that the rocks and dust disagree with the mathematicians.

Accordingly, I decided to attack the n-body gravitational problem not from the position of the mathematicians, but from the position of the rocks flying in space. I sought the solution in two steps: first I tried to figure out in detail how the rocks in space are physically flying under the influence of gravitation. The physical solution turned out to be extremely simple. Then I converted the physical solution to a mathematical model. The result was the unrestricted analytical solution valid for any number of bodies of unequal masses. You will find the resulting equations and all details of the conversion to the mathematical model in this book . Even though it is considerably more complex than the physical solution, the mathematical model is surprisingly simple. Who can now say that the unrestricted solution is impossible?


This is believed to be the first practical unrestricted analytical solution of the n-body gravitational problem, for unequal masses. Only trivial limitations apply to the values of the variables in the equations disclosed in the book: the masses of all bodies must be positive (and, of course, they may be respectively different); the bodies must be initially placed in respectively different positions (no two bodies are allowed in the same position).




CONSIDER THESE REVIEWS OF THE BOOK:


There are some concepts that are so complex that even the most learned of minds fail to grasp them. "N-Body Gravitational Problem: Unrestricted Solution" attempts to solve the unsolvable by offering a possible solution to one of the most controversial and debated topics in modern physics – the N-body gravitational problem. Claimed by Isaac Newton as simply incomprehensible to the human mind, this problem has baffled the world for over three centuries. Offering a new way of exploring the problem, "N-Body Gravitational Problem: Unrestricted Solution " is highly recommended for community library physics collections.

Whereas in Gravitation: Master Key to the Universe the author sets out his basic theory; N-Body Gravitational Problem: Unrestricted Solution looks at the actual workings of gravitation in a variety of differing circumstances. The first portion of this second book analyses how bodies actually react under the effects of gravitation. In this, the author is very thorough. His explorations do not simply reflect the findings of a single body being influenced by gravitation but also reflect various scenarios where the bodies vary in size or are being reacted upon by multiple gravitational carriers.

After methodically setting out all of the potential influences and creating a model, the second part of this book seeks to create a working set of formulas for any number of bodies. Although quite heady material, all of these calculations are intuitively presented with plenty of figures to illustrate each situation. The author is meticulous when it comes to defining and presenting each step so that his work can easily be understood and then replicated by the reader. In all cases, the work is well thought out and scientifically presented.

The book N-Body Gravitational Problem: Unrestricted Solution (ISBN 978-0-9689120-5-8) is a 6" x 9" trade paperback that has 96 pages and includes extensive bibliography and index. Since the book is mostly about mathematics, it expects from the reader the basic knowledge of calculus. However, the mathematics in the book is rather light when compared to typical scientific literature.
