Bringing the Supermarket to the Apocalypse

Chapter 503: Falling city

Views:

The secret of the Sky City floating in the air is the magical crystal. Without the energy of the crystal, the Sky City will fall from the sky.

Duke Uris just wanted to take control of the Sky City. He never thought about destroying this place. The moment he saw the forbidden land collapse, he knew that the matter was serious. If something happened to the crystal, everything about him would also become Bubble.

"Send someone immediately to find the person and carefully search for the whereabouts of the crystal. Go quickly!"

Under Juris's order, all the guards were dispatched to search for Gabriel's whereabouts. In fact, these guards knew that what Juris did was wrong, but now that the situation was determined, they could only act according to the order.

The ability of the 'Sky Crystal' is to control gravity and gravitational force. When the anti-gravity field and the gravity expansion field are implemented in the sky, the city in the sky floats in the sky. However, this energy is very unstable, so it is in the sky. Fixed protection in a forbidden area, rather than hidden protection. Now that the forbidden area has been destroyed, the Sky Crystal has broken away from the fixed protection, the gravity reaction field has become unstable, and the sky city has begun to fall off, and this phenomenon is still No one noticed.

Not long after, the guards and guards brought the unconscious Gabriel to Juris's side. Apart from the magic scripture placed next to Gabriel, they did not see the Sky Crystal. Instead, there were three crystal fragments. s things.

After seeing this thing, Yuris also knew that the matter was beyond his expectation. These fragments were the Sky Crystal. The broken Sky Crystal would lose its complete energy, and falling crystals began to appear in the Sky City. sign.

The concept of gravity needs to be elevated, broadened and deepened, and deserves serious study. To study gravity scientifically, we must first clarify the research environment of gravity, namely: research scope and reference system. Why still use a frame of reference? Because the kinematic acceleration is hidden in the concept of gravity! This is the "mystery" that is unearthed when promoting the concept of gravity.

The force that can make an object gain weight is not only the force of gravity, but also the force of inertia. Because they all act on every prime element of the object at the same time. Therefore, the concept of gravity has been upgraded to: the joint action of universal gravitation and inertia force that can make objects gain weight is called gravity. This is the depth of the concept of post-ascension gravity.

In physics, gravitation refers to the tendency of objects to accelerate closer together. Universal gravitation is one of the four basic interactions in nature. The other three interactions are electromagnetic interaction, weak interaction and strong interaction. Universal gravitation is the weakest force among the above-mentioned interactions, but it still has a greater attractive effect at super distances. In classical mechanics, gravitation is considered to be an action at a distance. According to the general theory of relativity, universal gravitation comes from the distortion of space-time due to the existence of mass. . In quantum gravity, gravitrinos are assumed to be the transport medium of gravity. Not long ago, an experiment overturned the speculation about the existence of 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 revolve around the sun in their own orbits, and the moon revolves around the earth in its own orbit, forming tides and other various natural phenomena that we observe. Gravity is what gives objects their weight.

The position of the center of gravity is related to the geometry and mass distribution of the object. An object with regular shape and uniform mass distribution has its center of gravity at its geometric center. For example, the center of gravity of a rod with uniform thickness is at its midpoint; the center of gravity of a ball is at the center of the sphere; the center of gravity of a square thin plate is at the intersection of two diagonals. The earth's gravity on an object seems to pull the object downward from its 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 within the object. The center of gravity of a truck changes with the amount of cargo loaded and the loading position, and the center of gravity of a crane changes with the weight and height of the lifted object.

Gravity isn't the only thing that gives objects weight! The object accelerates relative 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 an object's motion as the Earth rotates makes the object's gravity less than the gravitational force. Is there any essential difference between the acceleration of an object and the acceleration of other forms of motion of an object? No! Therefore, the acceleration of any form of accelerated motion of an object should be able to determine the amount of weight the object gains.

No version of the definition of gravity excludes the existence of other versions and occupies its own place in mechanics. The difficulty of establishing a definition of gravity has forced discussions about gravity to be avoided. This phenomenon, which is more difficult to understand in the science around us than in advanced science, does not conform to the laws of human understanding of the natural world.

Like gravity, elasticity, friction, electric field force, magnetic field force, etc., these forces are all 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 involve these processes. Gravity is a virtual force artificially imagined through scientific thinking based on existing theories. It is completely different from the birth of those actual power definitions. This is intrinsic to how gravity defines multiple reconstructions.

Losing the reaction field of gravity, the Sky City fell from the sky. The location where it fell was the current Death World. The abandoned forbidden land became the current safe base. It is said that the magic scripture was left in the forbidden land. , so the security base can block the attack of the apocalyptic tide. As for the science base in front of us now, it is the ruins of the palace.

Legends are generally not believable, but now the legends and real things overlap, everything proves that the legends are true. Combined with the special walls of the science base in front of you, it is easy to guess that there may be space here. Crystal fragments, otherwise there is really no reason to explain the specialness of this base.

Although this place is called the Old Science Base, even though the walls of the base are made of lead blocks, you can still feel the special energy field in the base. It is just because of the lead blocks that the source of energy in the base cannot be accurately analyzed, so It can only be analyzed based on the legendary things. There are definitely fragments of the Sky Crystal in the base.
