The secret of the Sky Castle's floating in the air is the magical crystal, and without the power of the crystal, the Sky Castle would fall from the sky. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Duke Yuris just wanted to get control of Sky City, he didn't think about destroying this place, the moment he saw the Forbidden Land collapse, he knew that something was serious, and if something happened to the crystal, everything about him would be in vain.

"Send someone to find out the person immediately, carefully search for the whereabouts of the crystal, go quickly!"

Under Yuris's orders, all the guards were dispatched to search for Gabriel's whereabouts, and these guards actually knew that Yuris's actions were wrong, but now that the situation was decided, they could only act according to orders.

The ability of the 'Sky Crystal' is the control of gravity and gravity, and the Sky City is floating in the air while implementing the anti-gravity ability field and the gravitational expansion field, but this energy is very unstable, so it will be fixed in a forbidden place, rather than a hidden protection, and now the forbidden land is destroyed, the Sky Crystal is out of fixed protection, the reaction field of gravity begins to be unstable, and the point of the Sky City begins to fall off, and no one has discovered this phenomenon.

After a short time, the guards and guards came to Yuris's side with the unconscious Gabriel, and apart from the magic tome placed next to Gabriel, they did not see the empty crystal, but there were three crystal shards.

Seeing this thing, Yuris also knew that things were beyond his expectations, these fragments were the Void Crystal, and the shattered Void Crystal would lose all its energy, and the Sky City would begin to show signs of falling.

The concept of gravity needs to be enhanced, broadened and deepened, and it deserves serious study. In order to study gravity scientifically, it is necessary to first clarify the research environment of gravity, that is: the scope of research and the frame of reference. Why do you still use a frame of reference? Because the concept of gravity hides the acceleration of kinematics! This is where the "mystery" that was unearthed when the concept of gravity was raised.

The force that gives weight to an object is not only the gravitational force, but also the inertial force. Because they all act on every prime element of the object at the same time. Therefore, the concept of gravity is elevated to the following: the combined effect of gravity and inertial force, which can make an object gain weight, is called gravity. This is where the concept of gravity after lifting comes in.

In physics, gravitational attraction refers to the tendency of objects to accelerate closer to each other. Gravitation is one of the four fundamental interactions in nature, the other three being electromagnetic, weak, and strong. The gravitational force is the weakest force in the above interactions, but it still has a large attractive effect at higher distances. In classical mechanics, gravitational force is considered to act at a distance. In general relativity, gravitation arises from the distortion of space-time by the mass of existence. In quantum gravity, gravitational neutrinos are assumed to be the transport medium of gravity. Not long ago, an experiment overturned speculation about the existence of a gravitational field.

The attraction of the earth causes nearby objects to fall towards the ground. Gravitation is responsible for the existence of galaxies such as the Solar System; Without gravitation, celestial bodies would not be able to attract each other to form a celestial system. Gravitation also causes the Earth and other celestial bodies to orbit around the Sun in their own orbits, the Moon to orbit around the Earth in its own orbits, forming tides, and a variety of other natural phenomena that we observe. Gravitational force is what makes an object gain weight.

The position of the center of gravity is related to the geometry and mass distribution of the object. An object of regular shape and uniform mass distribution has its center of gravity at its geometric center, for example, the center of gravity of a rod of uniform thickness is at his midpoint; The center of gravity of the ball is in the center of the ball; The center of gravity of a square sheet is at the intersection of two diagonals. The gravitational force of the earth on an object seems to pull the object down from the center of gravity. If you use other objects to support the center of gravity, the object will be able to maintain balance. But the position of the center of gravity is not necessarily above the object.

In the case of an object with uneven mass distribution, the position of the center of gravity is not only related to the shape of the object, but also to the distribution of mass within the object. The center of gravity of a truck changes with how much is loaded and where it is loaded, and the center of gravity of a crane changes with the weight and height of the object being lifted.

It's not just gravity that is what makes an object gain weight! The acceleration of the motion of the object with respect to the inertial frame, and the inertial force that "appears" in the non-inertial frame is also an important factor in making the object gain weight.

The acceleration of the accelerated motion of the object with the rotation of the earth makes the gravitational force of the object less than the gravitational force. Is this acceleration of an object fundamentally different from the acceleration of an object doing other forms of motion? No! Therefore, the acceleration of any form of acceleration motion of the object should determine the weight of the object.

There is no single version of the definition of gravity that excludes the existence of other versions and excludes its place in mechanics. The difficulty of establishing a definition of gravity has forced the discussion of gravity to be shunned. This phenomenon, which is more difficult to understand than advanced science, does not conform to the laws of man's understanding of the natural world.

Like gravitational force, elastic force, frictional force, electric field force, magnetic field force, etc., these forces are all objective real forces, and their definitions have been established on the basis of countless experiments, and their correctness has been proved by countless experiments. However, the establishment of the definition of gravity does not have these processes. Gravity is a fictitious force artificially imagined on the basis of pre-existing theories and through scientific thinking. It is completely different from the birth of those actual force definitions. This is what intrinsically factors that gravity defines multiple reconstructions.

Losing the reaction field of gravity, the city in the sky fell from the sky, and the location where it fell was the current world of death, and the abandoned forbidden land became the current safe base, and it is said that the magic holy book was left in the location of the forbidden land, so the safe base was able to block the attack of the apocalyptic tide, and as for the scientific base in front of me now, it is the ruins of the palace.

Legendary things are generally not credible, but now the legendary things and real things overlap, everything proves that the legend is true, combined with the special wall of the scientific base in front of you, it is easy to guess that there are likely to be fragments of the Sky Crystal here, otherwise there is really no reason to explain the special features of this base.

Although it is called the old science base, even if the city wall of the lead block is used in the base, you can still feel the special energy field in the base, but because of the lead block, you can't accurately analyze the energy source in the base, so you can only analyze it according to the legendary things, and there are definitely fragments of the empty crystal in the base.
