Investigation on the Consequences of a Strengthened Newtonian Gravity at Short Distances | Chapter 2 | New Insights into Physical Science Vol. 9

 In the middle ages, especially in astronomy and mechanics, the construction of the theory of movement of the solar planet system was a triumph of science. The confrontation that lasted for centuries between proponents of the Ptolemaic geocentric system and the heliocentric system of Aristarchus-Copernicus ended with the victory of the latter. A central interaction of bodies that is greater than Newtonian at short distances is considered. It is demonstrated that the velocity of escape from a body is essentially more than the velocity of escape provided by the theory of Newton. According to Newton's theorem, the Universal force Gravity is central, each mass m is attracted with force by another mass M in the Universe, The distance between the masses is inversely proportional to the quadrate and is directed along the axis, The cores of the masses bind. The relation of the latest core relationship with the A black hole's gravitational radius is observed. The gravitational radius of a black hole is shown to be They may be arbitrarily tall. The Black Hole (Dark Body) gravitation does not follow the classical It obeys the law of the essentially strong central gravitation (Newtonian) law of Gravitation.

Approximate Inertial Coordinate System Selections for Rotation Problems: The Gravitational Field of the Celestial Body Higher than the Object being Rotated: An Observational Study | Chapter 5 | New Insights into Physical Science Vol. 5

 

Selection of the coordinate system is essential for rotation problems. Otherwise, mistakes may occur
due to inaccurate measurement of angular speed. Approximate inertial coordinate system selections
for rotation problems should be the gravitational field of the celestial body higher than the object being
rotated: (1) the Earth fixed Cartesian coordinate system for normal rotation problem; (2) heliocentric -
a geocentric Cartesian coordinate system for satellites orbiting the Earth; (3) the Galaxy Heart -
heliocentric Cartesian coordinates for Earth's rotation around the Sun. In astrophysics, mass
calculation error and angular velocity measurement error lead to a black hole conjecture.

Physics Essay: Observation on Six Baseless and Irrational Problems in Modern Cosmology | Chapter 7 | New Insights into Physical Science Vol. 5

 

Analyzes the Big Bang theory, recession of galaxies, Hubble's law, multi-dimensional space, curved
space and a black hole in modern cosmology and points out that these six theories are all baseless
and irrational, contrary to classical science. Promotes the use of the plain view of the universe - the
materialist view of space–time-mass-energy to study the universe. The observations and
understanding of the universe are very limited now. Cosmology should be realistic, not based on
irrational models.
