Galilei And Einstein: Reflections On The Theory Of General Relativity. The Free Fall Of Bodies.

By Santo Armenia

We had studied Einstein’s Theory of General relativity starting from elementary phenomena, together with the Galileo's principle on free fall of bodies that represent his precondition. We underlined the discrepancy of Galileo's principle, as the mass of the test body is not being subtract from the mass of the earth, and because the reciprocal attraction between the bodies has not been evaluated. Furthermore, we highlight that the free fall takes place along radial vertical lines that are not parallel. Finally, we verify the consequence of the shape of solid bodies for Galileo's principle and Einstein's theory, Archimedes' principle and the weighing (mass) of the bodies.

Starting from elementary phenomena we study Einstein's theory of general relativity, together with Galileo's principle on free fall of bodies that represent his precondition. Galileo's principle estimates that all objects fall at a constant acceleration due to gravity regardless of their mass. On the contrary, we establish the non-effectiveness of that Galileo's principle as the mass of the test body is not being subtract from the mass of the earth (incorrectly thought to be constant) and moreover for not having been evaluated the reciprocal attraction of the bodies (superposition of effects). Likewise, we highlight that the free fall takes place along radial vertical lines that are not parallel. We study the shape of solid bodies, for which bodies that have the same mass but different shape (except from sphere, equilateral cylinder and cube) when varying their position on the reference plane they have different weight: a body a mass, a body infinite weight. Therefore, we verify the consequence of the shape of solid bodies according to the Galileo's principle (that is not effective) and for the confutation of Einstein's theory, Archimedes' principle and the weighing (mass) of the bodies.

Preface

of ATTILIO SIGONA¹

History teaches us that mankind has always been skeptical about any kind of innovation, and it has been  treated with aversion.

The transition from the Ptolemaic geocentric to the heliocentric Copernican conception was a real shock for science and humankind as well as for biblical scholars and the Church. It was not easy even to accept the evidence.

However, learning from the past is not something the human beings have been good at. It seems that humankind continues to show strong resistance to change and to scientific insight, not always because of justifiable conservatism.

I have followed the release of this book by ing. Armenia with the modesty of a person that is not much into physics that is not an expert of physics, but with the conviction that there were innovative theoretical elements.

First of all, the return of physics and mathematics to the philosophical sphere: which I consider a necessary stepback for the mankind’s benefit.

Secondly, an in-depth study of Galileo's physical principles of the fall of bodies and the shape of solid bodies, with all its implications for Einstein's theory of relativity and other practical aspects (in particular the measurement of the mass of solid objects) it has to be accepted with enthusiasm.

What’s most important is the author's attempt to reflect, to observe, to deduce and to start a confrontation. Not only does the author create a theory, but he also transforms his considerations into maths and physics formulas.

In addition, being the author so modest, he does not want us to call his reflections and considerations as theories but just reflections and considerations.

My final hope is that the scientific world could realize that the whole world would largely benefit from confrontation.

Galileo had to retract and was also imprisoned. Fortunately, nowadays, we do not run this kind of risks anymore.

The publication of this book is an invitation to scientific dialog and to in-depth knowledge this subject requires due to its implications with cosmic knowledge and the laws of the physical world.

Engineer Armenia does not consider himself a discoverer or a scientist: he has mostly reflected and only after he has then deduced. We believe that he is right.

Introduction

This is the second edition of a first never published. Its title was supposed to be:

Galileo Galilei and Albert Einstein

Free fall of bodies

Have we perhaps overlooked something?

Reflections on the theory of general relativity

as you can also see from the video named Armenia Santo Galilei of the 30 May 2017 that appears on  youtube.com/watch?v=6Ri_xAms45M.

Now the book name is the one on the cover.

While I was waiting for the publication of the first version, I worked on the new part.

Chapter I 

Evolution

Plato's innate ideas. The strength of public opinion.

The synchronism of Jung. ... To know is to remember. …

Mauro, my nephew, invites me to read Fabio Toscano's book (Sironi Editore): Il fisico che visse due volte.

He has recommended this book because it is a biography of the Russian physicist Lev Landau, who is the author of the physics textbooks he had studied at the University of Engineering of Catania.

I enrich myself with this experience: the scientist's life on the one hand and the writer's ability on the other.

My nephew recommends me to
