explains the fundamental reason why the wings of an aircraft can produce lift, and points out: Although the space capsule is highly sealed, when the space capsule lifts off or returns to the earth, due to the speed of the space capsule relative to the earth changes very fast, the air pressure in the space capsule will change rapidly, if the astronaut in the space capsule does not wear a space suit, the rapid change of air pressure can endanger the life of the astronaut.

explains the physical mechanism of inertial force and inertial centrifugal force，

3. The following paragraph is added to introduction：

Since the principle of strong equivalence and the principle of general relativity are the two basic principles on which general relativity is based [1] [2], relativity and quantum mechanics are regarded as the two pillars of modern physics. It can be seen that the modification and extension of the strong equivalence principle will have a great impact on physics.

General relativity, proposed by Albert Einstein in 1915, deals primarily with gravity and describes the large-scale structure of the universe. General relativity explains gravity as a geometric property of spacetime. Although general relativity has achieved great prestige, the following serious problems remain:

1) It is incompatible with quantum mechanics. [3] [4].

2) The gravitational problem of stars moving too fast around galaxies must be explained by the existence of "dark matter," which has not yet been detected.

3) It cannot explain the formation and disappearance of supermassive black holes. [5] [6] [7].

4) Black holes in general relativity [8] have singularities (points where the mass density tends to be infinitely large and the volume tends to be infinitely small)

5) General relativity does not reveal the physical mechanism of planetary perihelion precession [9] [10]. The general relativity only obtains the calculation result which is consistent with the observed data of the perihelion precession of Mercury through the approximate solution of the equation, but does not give the physical mechanism of the perihelion precession. Otherwise, it should be possible to calculate the precession of all the planets, it should not require dark matter to explain stars moving too fast around galaxies and galaxies moving too fast around clusters of galaxies, [5] and it should be possible to get a theory of black holes without singularities. [5].

6) General relativity's conclusion that gravitational redshift (the weaker the gravitational field, the longer the wavelength of light) is wrong. Based on the fact that time is faster with a weaker gravitational field and that time is proportional to radiosity [11], it is concluded that gravitational blue shift (the wavelength of light is shorter with a weaker gravitational field). However, experiments to verify the gravitational redshift of spectral lines cannot distinguish between gravitational redshift and gravitational blue shift [12].

7) General relativity does not explain why the inertial force is equivalent to gravity and considers the inertial force to be a fictional force.

8) General relativity plus special relativity does not explain Newton's bucket experiment. [13].

4. The following paragraph is added to Discussions：

2）How are inertial and Inertial centrifugal forces produced? Are they real forces?

An object accelerating in a straight line relative to the ether forms an ether field with decreasing energy density along the direction of acceleration in the internal space of the object, and each particle forming the object will be subjected to an ether pressure, that is, inertial force, along the opposite direction of acceleration. When an object is rotating in the ether, because the particle farther away from the rotation axis moves faster relative to the ether, an ether field with increasing energy density is formed in the inner space of the rotating object starting from the rotation axis and pointing in the direction perpendicular to the rotation axis. Each particle forming the object is subjected to an etheric pressure, or inertial centrifugal force, pointing away in a direction perpendicular to the axis of rotation. From the above analysis, it can be seen that the inertial force and the inertial centrifugal force, like gravity, are essentially etheric pressure and are real forces.

5. The following paragraph is added to Discussions：

4）Why is it difficult for a plane to take off downwind? Because in the case of a plane taking off downwind, it is difficult for the wing to cause the air above the wing to travel faster relative to the Earth than the air below the wing, and the higher the wind speed, the harder it is. So it's hard for a plane to take off downwind, and the higher the wind speed, the harder it is.

Why do two high-speed trains traveling in opposite directions repel each other when they meet? Because of the attraction between the molecules, the surface of the train drags a layer of air along with it, and the farther away from the surface of the train, the faster the air layer moves relative to the train (and the slower it moves relative to the ground). When two trains meet, the air layer dragged by the two trains will rub against each other, causing the speed of the air layer relative to the ground to decrease. So the speed of the air between the two trains relative to the ground is less than the speed on the other side of the two trains. Therefore, the air pressure between the two trains is higher than on the other side of the two trains, and the two trains repel each other.

6. The following paragraph is added to Discussions：

5）In 1971, after the Soyuz 11 capsule returned to Earth, three astronauts were found dead when the hatch was opened [20]. How did the three astronauts die? The author believes that the fact that none of the three astronauts in the capsule were wearing spacesuits during their return to Earth contributed to their deaths. The author also suggest that the capsule's tightness may not have been faulty, although the capsule is well sealed, but due to the severe slowdown of the capsule after entering the atmosphere, resulting in a rapid increase in air pressure in the capsule. Because the astronauts did not wear spacesuits, the pressure difference between the body and the outside increased dramatically, resulting in the death of the astronauts.
