Taschenbuch. Condizione: Neu. Neuware -The special relativity needs to be supplemented due to its defects and deficiencies¿this book first introduces the axiom of invariant equilibrium of force, a fact that has been widely recognized, derives a transformation formula of force for the special relativity from the above axiom, and verifies the transformation formula of force with deflection results of charged particle in magnetic field; in addition, proposes new concept of relative time dilation and absolute time dilation based on experimental results by J. C. Hafele and R. E. Keating, scientifically works out twin paradox and concludes that people are unable to travel in time. As for the general relativity, based on conclusion of the axiom of invariant equilibrium of force, different from inertia mass, the gravitational mass of an object is a constant irrelevant to kinematic velocity of the object. Only the object that moves at low velocity, such as the Earth, has inertia mass approximately equal to gravitational mass. The inference of the general relativity thus is true. This book comes up with many new ideas and concepts with simple and understandable analysis and deduction, which is believed to be inspired to readers.Books on Demand GmbH, Überseering 33, 22297 Hamburg 76 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -In base alla carica elettrica e al coefficiente elastico dell'oggetto indipendente dal moto dell'oggetto e in base alle proprietà simili del campo gravitazionale e del campo elettrostatico, si conclude che la massa gravitazionale dell'oggetto è una costante indipendente dal moto dell'oggetto. Tuttavia, i risultati sperimentali mostrano che la massa inerziale dell'oggetto è legata al moto dell'oggetto. Pertanto, si ritiene che il principio di equivalenza non sia soddisfatto. Quando l'oggetto si muove a bassa velocità, il principio di equivalenza è approssimativamente vero, quindi si conclude che la teoria generale della relatività è applicabile a tutti i corpi celesti dello spazio. Quando l'oggetto si muove ad alta velocità, il principio di equivalenza non è soddisfatto, quindi la teoria generale della relatività non è vera. In base al principio dell'equilibrio delle forze, si conclude che la velocità V del buco nero deve essere pari a zero. Sotto le condizioni necessarie di V = 0, l'esistenza del buco nero non può essere dedotta secondo la teoria generale della relatività.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Italienisch.

Neuware -Il presente lavoro propone l'assioma di invarianza dell'equilibrio delle forze e ricava la formula di trasformazione delle forze della relatività speciale; propone la legge di analisi delle correlazioni ed elimina alcuni problemi derivanti dall'applicazione impropria della relatività; propone il principio della velocità assoluta, determina la velocità di marcia di qualsiasi oggetto in movimento in tempo reale e risolve il problema del paradosso dei gemelli; propone il principio di corrispondenza e determina la relazione tra la massa a riposo e il quadro di riferimento; propone il concetto di trasformazione assoluta e di trasformazione relativa e chiarisce le due diverse nature della trasformazione di Lorentz; propone il principio di similitudine del campo e determina la massa gravitazionale come una costante che non ha nulla a che fare con la velocità; deduce che il principio di equivalenza è falso e che la relatività generale è applicabile solo agli oggetti in movimento a bassa velocità; propone il principio del doppio equilibrio gravitazionale e conclude che i buchi neri non possono esistere. Analizza inoltre la velocità limite delle astronavi con equipaggio e conclude che gli esseri umani non possono realizzare viaggi nel tempo di rilevanza pratica.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Italienisch.

Taschenbuch. Condizione: Neu. Neuware -It is pointed out that the magnetic field is not an independent real substance and it is considered that the electromagnetic field containing non-material magnetic field cannot establish a unified field theory with the gravitational field of the real substance.Through analysis, it is concluded that the so-called magnetic field is essentially a motion state of the electric field.The magnetic field is defined as the electric field contracting in motion.According to this definition,the Biot-Savart,Lorentz force,electromagnetic induction,displacement current and Ampere loop laws are deduced and proved.Through the experimental results of electrostatic field around the permanent magnet,it is proved that the magnetic field is indeed the electric field contracting in motion.It is believed that the electrostatic field is similar to the static gravitational field,the electric field contracting in motion can be defined as a magnetic field,and the gravitational field contracting in motion can also be defined as a similar contraction field,so that the electromagnetic field is completely similar to the gravitational contraction field,and the unification of the two fields is an inevitable result.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -According to the electric charge and the elastic coefficient of the object independent of the motion of the object, and based on the similar properties of the gravitational field and the electrostatic field, it is concluded that the gravitational mass of the object is a constant independent of the motion of the object. However, experimental results show that the inertial mass of the object is related to the motion of the object. Therefore, it is considered that the principle of equivalence is not satisfied. As the object moves at a low velocity, the principle of equivalence is approximately true, so it is concluded that the general theory of relativity is applicable to all space celestial bodies. When the object is moving at high velocity, the principle of equivalence is not satisfied, so the general theory of relativity is not the truth. According to the principle of force balance, it is concluded that the velocity V of the black hole must be zero. Under the necessary conditions of V = 0, the existence of the black hole cannot be deduced according to the general theory of relativity.Books on Demand GmbH, Überseering 33, 22297 Hamburg 56 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Aufgrund der elektrischen Ladung und des elastischen Koeffizienten des Objekts, die von der Bewegung des Objekts unabhängig sind, und aufgrund der ähnlichen Eigenschaften des Gravitationsfeldes und des elektrostatischen Feldes wird geschlossen, dass die Gravitationsmasse des Objekts eine von der Bewegung des Objekts unabhängige Konstante ist. Die experimentellen Ergebnisse zeigen jedoch, dass die träge Masse des Objekts mit der Bewegung des Objekts zusammenhängt. Daher wird davon ausgegangen, dass das Äquivalenzprinzip nicht erfüllt ist. Bewegt sich das Objekt mit geringer Geschwindigkeit, ist das Äquivalenzprinzip annähernd erfüllt, so dass die allgemeine Relativitätstheorie auf alle Himmelskörper anwendbar ist. Bewegt sich das Objekt mit hoher Geschwindigkeit, ist das Äquivalenzprinzip nicht erfüllt, so dass die allgemeine Relativitätstheorie nicht zutrifft. Nach dem Prinzip des Kräftegleichgewichts wird gefolgert, dass die Geschwindigkeit V des Schwarzen Lochs gleich Null sein muss. Unter den notwendigen Bedingungen von V = 0 kann die Existenz des Schwarzen Lochs nicht aus der allgemeinen Relativitätstheorie abgeleitet werden.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Deutsch.
