Quantum mechanical evidence fortune-telling _ quantum mechanical fortune-telling method
Your question is the ultimate question about the origin of matter, and there is probably an infinite way to go before it is really solved.
Gravity is far more complicated than electromagnetic force (for example, Einstein's gravitational field equation is a typical nonlinear partial differential equation group, while Maxwell's equation describing electromagnetic field is linear, which is an important reason why general relativity is abstruse-the mathematics involved is too difficult). Gravity is more essential than electromagnetic force (electromagnetic force, weak force and strong force have been brought into the framework of quantum gauge field theory and proved by many experiments, but gravity is still stubborn and difficult to compare with quantum theory.
General relativity geometrizes gravity-it thinks that the bending of space-time caused by matter and its motion is universal gravity, and there is no such force as gravity in the calculation of general relativity. Instead, it studies how space-time is specifically curved, how objects move along the shortest path (geodesic) in this curved space-time, and how to treat this inertial motion (which often seems to be accelerated motion) in a specific coordinate system. As always, quantum field theory regards force as the interaction of medium particles, and it guesses that gravity is transmitted by gravitons.
General relativity is a contemporary theory of gravity. Like Newton's theory of gravity, it is only an imperfect relative truth, and there will be a better theory of gravity beyond it in the future. Although it is not clear what specific form the future theory will take, some of its characteristics have begun to take shape: in short, most physicists agree that it should include quantum mechanics, the gravitational field should be quantized, and the gravity should be transmitted by real or imaginary gravitons.
As one of the two cornerstones of modern physics, the core of quantum mechanics is Heisenberg's uncertainty principle. It tells us that in a limited time, the energy of any object is not absolutely certain. From this, we can simply estimate the size of a single virtual graviton that binds the earth from the sun. In a word, the sun emits a graviton, which is equivalent to reducing its energy a little. If the solar energy recovers a graviton of the same size in a period of time t, and the product of e and t is not greater than Planck constant h, then no one can measure that the sun has reduced the energy of e so much during this period. (This is not to say that human measurement means are insufficient, but that it cannot be measured in principle, otherwise it will violate the first principle of quantum mechanics-the uncertainty principle. So we can only think that the sun has always been a conservation of energy, and the gravitons it spits out and swallows are empty. Gravitator also flies at the speed of light. The shortest time for it to travel back and forth between the sun and the earth is 16 minutes, and the corresponding upper mass limit of a single graviton is of the order of 10-53kg. In order to understand how small gravitons are, we might as well compare the photons emitted by the sun. Take the yellow-green photon that emits the most as an example, its mass is about 4 * 10-36 kg, which is hundreds of thousands of times smaller than the electron mass, but it is 18 orders of magnitude larger than the above graviton-several billion times! Compared with the light pressure of the sun on the earth, the gravity between the sun and the earth is extremely huge; The particles subjected to these two forces have the opposite contrast-how small a single graviton is compared with a single photon. ...
