Bringing the Supermarket to the Apocalypse

The secret of the sky city floating in the sky is the magical crystal. If there is no energy of the crystal, the sky city will fall from the sky.

Duke Juris just wanted to gain control of Sky City. He never thought of destroying this place. The moment he saw the forbidden land collapse, he knew that things were serious. If something happened to the crystal, everything about him would become Bubbles.

"Immediately send someone to find him, carefully search for the whereabouts of the crystal, go!"

Under the order of Uris, all the guards were sent out to search for Gabriel's whereabouts. These guards actually knew that what Uris did was wrong, but now that the situation is fixed, they can only act according to the order.

The ability of the 'Crystal of the Sky' is to control gravity and gravitational force. When the anti-gravity field and gravitational expansion field are implemented in the sky, the city of the sky is floating in the air, but this energy is very unstable, so it will be in the sky. Fixed protection is carried out in a forbidden area, rather than hidden protection that can be done. Now that the forbidden area is destroyed, the crystal of the sky has broken away from the fixed protection, the reaction field of gravity has become unstable, and the sky city has begun to fall off, and this phenomenon still exists. No one found out.

Not long after, the guards and guards came to Yuris with the unconscious Gabriel. Except for the magic scripture placed next to Gabriel, they did not see the crystal of the sky, but there were three crystal fragments. s things.

After seeing this thing, Yuris also knew that things were beyond his expectations. These fragments are the crystals of the sky. The broken crystals of the sky will lose their complete energy, and the city of the sky will also start to appear. sign.

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

The force that can make objects gain weight is not only gravitation, but also inertial force. Because they all act on every quality element of the object at the same time. Therefore, the concept of gravity is promoted to: the joint action of gravitation and inertial force that can make objects gain weight is called gravity. This is the depth of the concept of gravity after ascension.

In physics, gravitation refers to the tendency of objects to accelerate closer together. Gravity is one of the four fundamental interactions in nature, the other three are electromagnetic interaction, weak interaction and strong interaction. The gravitational force is the weakest force in the above interactions, but the gravitational force still has a relatively large attractive effect at a distance. In classical mechanics, gravitation is considered to be an action at a distance. In the general theory of relativity, universal gravitation comes from the distortion of space-time by mass. . In quantum gravity, gravitons are assumed to be the gravitational transport medium. Not long ago, an experiment overturned the speculation of the existence of the gravitational field.

The Earth's attraction causes nearby objects to fall toward the ground.

Universal gravitation is the reason why galaxies such as the solar system exist; without universal gravitation, celestial bodies would not be able to attract each other to form a celestial system. Gravity also makes the earth and other celestial bodies orbit the sun in their own orbits, the moon orbits the earth in its own orbit, creating tides, and various other natural phenomena that we observe. Gravity is what makes objects gain weight.

The position of the center of gravity is related to the geometric shape and mass distribution of the object. The center of gravity of an object with regular shape and uniform mass distribution is at its geometric center. For example, the center of gravity of a rod of uniform thickness is at its midpoint; the center of gravity of a ball is at the center of the ball; the center of gravity of a square thin plate is at the intersection of two diagonals. The gravity of the earth on the object seems to be pulling the object down from the center of gravity. If other objects are used to support the center of gravity, the object can maintain balance. But the location of the center of gravity is not necessarily above the object.

For objects with uneven mass distribution, the position of the center of gravity is not only related to the shape of the object, but also related to the distribution of mass inside the object. The center of gravity of a truck changes with the amount and location of the load, and the center of gravity of a crane changes with the weight and height of the lifted object.

Gravity is not the only factor that makes objects gain weight! The object accelerates relative to the inertial system, and the inertial force "appearing" in the non-inertial system is also an important factor for the object to gain weight.

The acceleration of the object's motion with the acceleration of the earth's rotation makes the gravity of the object smaller than the gravitational force. Is there any difference between the acceleration of the object and the acceleration of other forms of motion? No! Therefore, the acceleration of any form of accelerated motion of an object should be able to determine the weight of the object.

There is no one version of the definition of gravity that excludes the existence of other versions and has its own place in mechanics. The difficulty of establishing a definition of gravity makes the discussion of gravity far away from everyone. This phenomenon that the science around us is more difficult to understand than the advanced science does not conform to the laws of human understanding of the natural world.

Such as gravitational force, elastic force, frictional force, electric field force, magnetic field force, etc., these forces are real forces that exist objectively, their definitions are established on the basis of countless experiments, and their validity has been proved by countless experiments correctness. But the establishment of the definition of gravity does not have these processes. Gravity is a virtual force artificially imagined on the basis of existing theories and through scientific thinking. It is completely different from the birth of those actual power definitions. This is what gravity defines intrinsically for multiple reconstructions.

Losing the reaction field of gravity, Sky City fell from the sky. The place where it fell is the current world of death. The abandoned forbidden area has become the current safe base. It is said that the magic scriptures are left in the forbidden area. , so the security base can block the attack of the tide of the end of the world. As for the science base in front of us now, it is the ruins of the palace.

The legends are generally not credible, but now the legends and the real things overlap, and everything proves that the legends are true. Combined with the special city walls of the science base in front of you, it is easy to guess that there may be a space here. A shard of crystal, otherwise there's really no reason why this base is special.

Although it is called the Old Science Base, even though the city walls of lead blocks are used in the base, you can still feel the special energy field in the base, but the source of energy in the base cannot be accurately analyzed because of the lead blocks, so It can only be analyzed according to the legend, there are definitely fragments of the crystal of space in the base.
