The study, published Aug. 16 in the journal Science, shows that gravity works exactly as Einstein predicted, even at the outermost edge of a black hole — in this case, Sagittarius A*, the supermassive black hole at the center of our Milky Way. But the study is only the first salvo in a wide-ranging attempt to find the point where Einstein`s model collapses. To make matters worse, proponents of gravity theory speculate about mysterious things called gravitons and gravity waves. These were never observed, and when some gravity wave detection reports were published, the physicists involved had to quickly retract them. Any report of anti-gravity and gravity waves quickly triggers laughter. This is not a child-friendly theory. And even children can see how ridiculous it is to imagine the Australian people standing upside down against us, as the theory of gravity would have it. If this is an example of the predictive power of gravitational theory, we can see that there is no basis at the base. In 1604, Galileo advanced the correct hypothesis that the distance of a falling object is proportional to the square of the elapsed time.  This was later confirmed by the Italian Jesuit scholars Grimaldi and Riccioli between 1640 and 1650. They also calculated the amplitude of gravity by measuring the oscillations of a pendulum.
 The theory of gravity violates common sense in many ways. Followers, for example, have a hard time explaining why planes don`t fall. Since antigravity is rejected by the scientific establishment, they resort to a lot of hand agitation. The theory implies, if taken seriously, that the default position of all aircraft is on the ground. While this seems to be true for Northwest Airlines, it appears that JetBlue and Southwest have a superior theory that effectively harnesses forces that defy so-called gravity. But Newton`s vision of gravity didn`t work for some things, like Mercury`s particular orbit around the sun. The orbits of the planets change over time, and Mercury`s orbit has moved faster than Newton had predicted. But Newton`s law of universal gravity extends gravity beyond Earth.
Newton`s law of universal gravity concerns the universality of gravity. Newton`s place in the Gravity Hall of Fame is not due to his discovery of gravity, but to his discovery that gravity is universal. ALL objects attract each other with gravitational pull. Gravity is universal. This gravitational attraction depends directly on the masses of the two objects and is inversely proportional to the square of the distance separating their centers. Newton`s conclusion on the magnitude of gravitational forces is symbolically summarized as follows: Finally, the mere name “universal theory of gravity” or “theory of universal gravity” (secularists like to use confused language) has a distinctly socialist connotation. The central idea of “to each according to his weight, to each according to his mass” is communist. There is no reason why gravity should apply equally to the just and the unjust, and for the saved to be freed from such “universalism.” If we have universal gravity now, universal health coverage will surely follow. It is this kind of universalism that consumes the moral fiber of a nation. It is not even clear why we need a theory of gravity: there is not a single mention in the Bible, and the patriotic founding fathers never referred to it.
The second conceptual remark that needs to be made about the above calculation examples is that using Newton`s universal gravitational equation to calculate gravity (or weight) produces the same result as when calculating with the equation shown in unit 2: it is unlikely that the law of gravity will be abrogated given the current geopolitical climate. But there is no need to teach unfounded theories in public schools. There is indeed evidence that the theory of gravity has serious implications for morality. Activist judges and left-wing teachers often use the phrase “what goes up must go down” to describe gravity, and relativists have been quick to apply this to moral standards and shared decency. First, no one has measured gravity for every atom and star. It is simply a religious belief that it is “universal.” “It is very difficult to predict how new discoveries in fundamental physics will affect our daily lives,” Lu said. “But a new theory of gravity could help us understand how our own universe came into being and how we got to where we are today 13 1/2 billion years later.” “Newton had fun with his description [of gravity] for a long time, and then at some point it became clear that that description was fraying around the edges, and then Einstein offered a more complete version,” said Andrea Ghez, an astrophysicist at UCLA and co-chair of the new research. “And so today we`re back to the point where we understand that there has to be something broader that allows us to describe gravity in the context of black holes.” In December 2012, a team of researchers in China announced that they had taken measurements of the phase delay of Earth`s tides to full and new moon, which seems to prove that the speed of gravity is equal to the speed of light.  This means that if the sun suddenly disappeared, the Earth would normally orbit the free point for 8 minutes, which is the time it takes for light to travel that distance. The team`s findings were published in the Chinese Science Bulletin in February 2013.  In the ancient Middle East, gravity was hotly debated.
The Persian intellectual Al-Biruni believed that gravity was not only on Earth, and he rightly assumed that other celestial bodies should also exert gravitational pull.  In contrast, Al-Khazini took the same position as Aristotle that all matter in the universe is attracted to the center of the earth.  Today, Newton`s law of universal gravity is a widely accepted theory. It guides scientists` efforts in the study of planetary orbits. Knowing that all objects exert gravitational influences on each other, small perturbations in the elliptical motion of a planet can be easily explained. When the planet Jupiter approaches the planet Saturn in its orbit, it tends to deviate from its otherwise smooth orbit; This deviation or perturbation can be easily explained by considering the effect of the gravitational pull between Saturn and Jupiter. Newton`s comparison of the acceleration of the apple with that of the moon led to a surprisingly simple conclusion about the nature of gravity woven into the entire universe. All objects attract each other with a force directly proportional to the product of their mass and inversely proportional to their distance.
Gravity is more accurately described by general relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of space-time caused by the uneven distribution of mass, causing masses to move along geodesic lines. The most extreme example of this curvature of space-time is a black hole from which nothing – not even light – can escape once it crosses the black hole`s event horizon.  For most applications, however, gravity is well approximated by Newton`s law of universal gravity, which describes gravity as a force that causes any two bodies to be attracted to each other, with a size proportional to the product of their masses and inversely proportional to the square of the distance between them: Despite its success in predicting the effects of gravity on a large scale, general relativity is ultimately incompatible with quantum mechanics. This is because general relativity describes gravity as a smooth, continuous distortion of spacetime, while quantum mechanics claims that all forces come from the exchange of discrete particles called quanta. This contradiction particularly annoys physicists because the other three fundamental forces (strong force, weak force and electromagnetism) were reconciled with a quantum framework decades ago.  As a result, modern researchers have begun to look for a theory that could unite both gravity and quantum mechanics in a more general framework.  OK, choose an item that won`t break, dent the ground, do damage, or cause trouble for either of us. Hold it in front of you and let it go.
What is going on? It falls unless you have selected a helium balloon. In this case, gravity makes it float upwards by pulling towards the air around the balloon with more force). The gravitational pull between the earth and the object pulls them towards the ground. But if we conduct this experiment, should we talk about the law of gravity or the theory of gravity? On Earth, gravity gives weight to physical objects, and the moon`s gravity is responsible for sublunar tides in the oceans (the corresponding antipodian tide is caused by the inertia of the Earth and the Moon orbiting each other).
