Chapter 775: Not magic

(The science and technology principle of the novel is pure nonsense, if I can study it out ...)
The small metal ball is suspended in the air. This is not a model, but the latest achievement of technology.
"God!" George saw an example of earth's gravitation being ineffective for matter, and he glared at Yan Jing: "Is this the cancellation of gravitational waves?"
Xu Limin said: "The superstring is invisible and intangible, but can be observed through its derivative effects. Gravitational waves formed at specific frequencies are one of the ways we observe superstrings."
Xu Limin said, "Through the superstring theorem, we know that the superstring is the smallest unit in the universe and the smallest unit that constitutes all matter. Then as far as the earth is concerned, such a huge mass sphere is also composed of the smallest unit in the universe. In this large-mass sphere, there will also be some super-strings with specific frequencies to form a sphere of mass, and the gravitational force corresponding to the sphere of mass. This is the interpretation of gravity by Einstein's theory of relativity. "
"So what about the metal on the stage now? The are hollow, and there are specific frequencies of superstrings that we have collected experimentally. In metal balls, they are combined into gravitational waves. Let the ball also have its own gravitational wave corresponding to its equivalent mass. This gravitational wave can cancel the gravitational wave of the earth. The ball is like floating water, and it floats in the air. "
Xu Limin's explanation made reporters sound very entangled, but physics experts knew what Xu Limin was saying.
Prior to the establishment of the superstring theorem, the universal gravitation formula was the best formula to explain gravity. Universal gravity is proportional to the product of the masses of two objects.
Then after the superstring came out, Xu Limin's team added an indefinite parameter to the gravitational formula, which is the vector of the superstring related to the specific frequency of gravity.
Note that it is a vector, which is directional.
After this modification, the gravitational formula is not only related to the mass of the object but also to the superstring.
In other words, the object reaches a balance of gravity at a certain distance from the ground and levitates in the air.
"So, the metal ball will look like this ..." Xu Limin said that he pressed the metal ball with the palm of his hand. The metal ball seemed to float on the water. After being pressed down, Xu Limin let go and quickly rebounded. Then it waved up and down in the air, and finally stayed in its original position.
"This is how gravitational waves from superstrings affect objects."
Xu Limin playing with metal is like magic.
Xu Limin may not have thought at this time. He just pressed the metal ball down and then the metal ball rebounded. This model is a future enhanced version of the gravitational slingshot. The enhanced version of the gravitational slingshot will help human aircraft to explore deeper. universe.
"What if we just apply horizontal forces to the metal balls?"
Xu Limin fiddled with the metal ball gently, and the metal ball moved forward in balance in the air, and then stopped slowly.
This series of experiments opened the eyes of the experts on the stage, and the truth of physics was best interpreted in the metal ball. Human physics has also reached unprecedented heights because of this metal ball.
Some European media have questioned the arrangement of the podium, because of the light and location, they have no way to determine whether these metal have traction ropes on them, or the metal are magnetic originally, and the bottom of the stage is originally electromagnetic boards. The magnetic levitation effect suspends the ball in the air.
BBC reporters continued their impolite tradition, and he politely interrupted Xu Limin's speech, saying aloud, "Can we check if your metal are problematic?"
The voice was loud and harsh, and the staff at Pangu Science and Technology Field wanted to invite this impolite reporter out.
Xu Limin gave the reporter a chance. He didn't care about the reporter's interruption and continued to explain.
But the BBC reporter seems to think that Lao Tzu is the best in the world, and if you do n’t answer my question, I will spare you.
He continued with a loud interruption and said: "Please Professor Xu to answer this question. We have reasons to suspect that your metal ball is defective. Can you give me the metal ball and we will check it."
This time, Xu Limin was rude, he said, "Please ask the security personnel at the scene to invite someone who violates the discipline of the conference."
Security personnel entered quickly, and the two invited the BBC reporters out of the way.
The BBC reporter still shouted in his position: "You are unwilling to answer this question, which proves that your results are problematic and your metal pellets are problematic!"
"Let me go! Let me go! You are interfering with the freedom of the press! Please let me go!"
The protest was invalid, and BBC reporters were released like dead pigs.
The scene finally quieted down.
Xu Limin said with a smirk: "It is not that I am unwilling to answer questions from reporters ~ EbookFREE.me ~ but I am not willing to answer questions from impolite people. The quality of being a reporter should not be arrogant but humble respect."
After speaking, Xu Limin quickly answered a question from the BBC reporter. He threw it hard and the metal ball was thrown into the audience.
The move surprised everyone, and something magical happened.
The metal ball did not fall on the ground, but continued to float in the air after bouncing in the air for a while.
Coincidentally, the metal ball fell in front of George.
George picked up the metal ball with his hand and studied it carefully. If he was in a balanced position with the ground, George could not feel the gravity of the metal ball.
Gravity is an expression of gravity on Earth.
George pressed the metal ball down with his hand, and he could feel the upward force of the ball tomorrow, which is similar to the buoyancy of pressing a suspended wooden block down in the water.
George lifted the metal ball up again, and felt the downward force of the ball, which was similar to gravity.
George can confirm that the ball is made of stainless steel!
The facts are right in front. This is not a deceptive trick, but a real reality!
Xu Limin said: "This metal ball is worth 50 million soft sister coins, and now I give him to a fate. The gravitational waves in the metal ball are balanced in a short time, but as the combination of superstrings changes, Attenuation, it will eventually decay to 0. I will give you this ball, and you can take it back to your laboratory and use the law of conservation of momentum to measure the mass of the metal ball. "
The scholars in the audience looked at the metal ball in front of George, and didn't know what to say for a while.
Xu Limin laughed: "The metal ball is just the beginning, and there is a big guy."
