Chapter 576 The Nature of Gravitation
As he spoke, Xu You opened his computer and found his design plan for the space gravity system.
Compared with Lu Zhiyao's design, Xu You's design is much more detailed.
However, Lu Zhiyao's picture was just a casual one, and it certainly could not be compared with the one carefully designed by Xu You.
The overall design specifications of the two are almost the same, which proves that Lu Zhiyao does have very professional abilities.
"Master's wife and teacher definitely didn't discuss it secretly and deliberately put on such a show. They definitely wouldn't be that bored. I didn't expect Master's wife to be so powerful. It really exceeded my imagination."
Lin Shi muttered silently in her heart, and couldn't help but feel admiration for Lu Zhiyao.
Xu You naturally had never studied similar details with Lu Zhiyao before. The reason why Lu Zhiyao was able to master this knowledge was due to her usual efforts and her increasingly powerful brain power.
"Using centrifugal force to simulate gravity and create an artificial space gravity system is currently the most likely and safest way to create space gravity. However, its disadvantage is that the spacecraft must be large enough, which will be a great test for the carrying capacity of our rockets. We will definitely launch such a large space station that can use centrifugal force to simulate gravity in the future."
Having said that, Xu You changed the subject.
"It is still unknown when we can launch such a huge space station. Therefore, in addition to using centrifugal force to simulate gravity, we also need to try to find other ways to simulate gravity on Earth."
After listening to what Xu You said, everyone fell into a brief silence for a moment.
Indeed, using a huge space station to simulate gravity is indeed the most feasible method at present.
However, although this method is feasible in theory, it is not easy to implement.
At this time, Lin Shi said half-jokingly:
"It would be nice if we could invent a gravity coating like in science fiction novels and movies. Apply gravity coating on the bottom of the spacecraft and install negative mass material on the top of the spacecraft, so that we can simulate a gravity environment similar to that on Earth. Alas, these are all science fiction and there is no complete scientific theory to support them. "
It cannot be said that Lin Shi’s ideas are completely unrealizable, but even the theoretical part is not supported.
However, these ideas provided Xu You with some inspiration, allowing Xu You to immediately enter the flow state and think about other possibilities.
"Teacher... have you entered that state again?"
Lin Shi noticed Xu You's unusual changes, but Lin Shi was already accustomed to Xu You like this, and knew that when Xu You was silent, almost in a meditative state, he must not be disturbed.
The others also knew Xu You's habit, and they all shut their mouths at the same time, waiting for Xu You to think.
"Whatever force it is, as long as it can produce an effect similar to gravity, it can solve the problem. Let's try the possibility of pressure first."
The first thing Xu You thought of was to use pressure to replace gravity and achieve an effect similar to gravity.
But soon, after simulation in Xu You's brain, Xu You denied the possibility of this direction.
Using pressure can indeed make the human body feel the force of gravity on a macro scale, but for the human body itself, the feeling is completely different.
These pressures then act on the surface of the human body and not on the inside of the body.
This feeling is like being in deep water and being under strong pressure from the water, which makes people feel uncomfortable.
"Universal gravity actually acts on every particle in the human body. Only forces based on the same principle can achieve nearly the same effect."
This is why a similar effect can be produced by utilizing the centrifugal force caused by rotation.
"Wait a minute... What is the essence of gravity ?"
At this time, Xu You thought of another problem.
According to the understanding in the textbook, according to the formula of universal gravitation, universal gravitation is proportional to the product of the masses of two mutually attractive objects, and inversely proportional to the square of the distance between the two objects.
If we understand it more deeply, the essence of gravity is the distortion of space and time.
The more massive an object is, the greater the curvature of the space-time around it.
When a small object passes near a large object, it will be affected by this curvature and fall near the large object.
This influence, from a mechanical point of view, is manifested as the so-called "gravity".
But at this time, Xu You did not think that the essence of gravity was just this.
Xu You immediately thought of another force, Coulomb force.
This is a force between two electric charges, calculated using a formula very similar to that of gravity, with charge substituted for mass and different coefficients.
According to the space-time distortion theory of gravity, it is not difficult to understand why the two forces are very similar in form.
However, Xu You felt that the phenomenon that the two forces were expressed in very similar ways could reveal some hidden relationship between mass and charge.
"The amount of electric charge carried by protons and electrons is exactly the same, but their masses differ by nearly two thousand times. Can we assume that protons actually contain a positron and other uncharged particles?" Xu You thought.
Thinking of this, Xu You began to simulate a more microscopic universe in his brain.
In previous simulation experiments on controlled nuclear fusion, Xu You was able to simulate it at the quantum level.
Looking at the more microscopic world in his mind, Xu You discovered some new information.
"Sure enough, the composition of protons is not as simple as quarks and gluons. They can be further broken down. Including the 62 kinds of elementary particles, they can all be further broken down."
Due to the limitation of his brain power, Xu You is currently unable to see clearly what kind of particles the more precise particles are.
But at this time, Xu You already had a bold guess.
Perhaps the even smaller particles that make up these elementary particles are simpler than we thought.
Just like in Go, there are so many complex variations, but the basic pieces are only two types: black and white.
After completing this series of complex thoughts in his mind, Xu You finally broke out of the flow state.
Only then did Xu You realize that he was still discussing various ideas about the space gravity system with everyone in the laboratory.
