Can gravity be shielded? If gravitational waves can be shielded like electromagnetic waves, will it form antigravity?
This is a very important scientific issue for interstellar civilization.
According to relevant theories, gravity does not act at a distance. It also requires a medium to propagate at the speed of light in space. The transmission medium is called a graviton.
If these gravitons are taken away, will gravity be blocked? Just like light, if a piece of wood is used to block the photons, it will be difficult for the light to propagate. Is there anything that can isolate the gravitons?
The manipulation of gravitons has always been a key research project of Green Light Civilization. They know that anti-gravity technology is a path to a stronger civilization.
If the essence of gravity is indeed gravitons, it is possible to imitate the "superfluid phenomenon" in condensed matter to construct a superfluid of gravitons. If this superfluid surrounds a limited area that you want to shield, then the superfluid can be used
Under normal circumstances, the graviton flow flowing through this area is short-circuited, thereby achieving a local shielding effect.
This is a gravitational shield in the true sense, which can limit the "gravity" to a certain area and even control it to a certain extent!
Greenlight people speculate that the devices related to neutron star fragments are based on this principle. As long as the switch is pressed, the external gravity disappears, which is really amazing.
However, this kind of true anti-gravity technology is really too difficult. Thousands of years have passed, and green light scientists have made no achievements in this area. They have truly felt the many theoretical limitations.
They even suspected that the technology tree of Green Light Civilization was misled by this neutron star fragment. This kind of god-like technology is not what their current science and technology can achieve!
The anti-gravity technology of other civilizations may not be this method of removing fuel from the pot at all, but other simpler technologies: such as ultra-high voltage electric fields and spin polarization.
After the second emergency meeting, the crazy radicals had taken over the majority.
The Green Light people were determined to completely abandon this neutron star fragment and their main ship... and give their enemies a hard blow!
According to the planned plan, the Green Light people have prepared a spare space shuttle with a length of about ten kilometers. They will use this small space shuttle to return to their home planet. Because the space inside the space shuttle is really limited, most members will
Hiding in the hibernation cabin and sleeping, only a small number of operators are active, responsible for controlling the spacecraft.
This is an extremely dangerous behavior, just like abandoning an aircraft carrier in the vast sea and taking a small motorboat to cross the ocean. But the Green Light Man’s brain is just like this, and this kind of revenge definitely meets the requirements of "etiquette".
Any rebuttal is powerless, and it is worth doing even if it is dangerous.
And their original main ship will continue to stay in the solar system to act as a decoy! Intelligent programs are responsible for timing control. When the enemy's super fleet approaches the solar system, they will be given a cruel blow...
Although this super fleet is powerful, it is still far behind the god-like super civilization. They will definitely not be able to withstand a supernova explosion.
At the same time, the Green Light people are very confident that their precious gifts can satisfy the "new human civilization" and cooperate with their plans... because they are already bleeding heavily!
More than ten hours later, Noah's gravitational wave telescope suddenly observed that the dot representing the green light spacecraft weakened significantly, and then moved slowly. At the same time, people received an urgent message that the green light civilization was developing.
Came here.
"The gravity has decreased? Are they leaving?"
Yu Yifeng's heart moved slightly, and he immediately clicked on the message, still thinking that he would finally send these plague gods away.
At the very beginning of this message, the Green Light Civilization first boasted about the generosity of the "New Human Civilization". Their Green Light Civilization was extremely grateful. Moreover, all of them had already left on the backup space shuttle and specifically said goodbye to mankind...
…
Seeing this, Yu Yifeng felt slightly confused. Isn't the opponent's main ship still there? How come the people have escaped? Could it be that the main ship was abandoned? Can humans pick up garbage again?
Yu Yifeng was inexplicably moved.
Then, the Green Lantern changed the topic and cursed the "Destroyer Civilization" that brought them unprovoked wars, as well as their unrelenting hatred...
Okay, okay, humans have guessed most of these things, just run away, don't talk nonsense, there is nothing to be ashamed of... This is what Yu Yifeng thinks in his mind.
It's normal to run away if you can't fight.
As he continued to read, his face suddenly changed drastically, and his temples twitched, as if he couldn't believe it. These contents were so surprising and shocking! He bit his lip, and a burst of blood instantly appeared in his mouth.
Only under the stimulation of severe pain could he wake up a little.
Although he has received a lot of stimulation in the past few days and his mental endurance has improved a lot, Yu Yifeng still can't help but want to curse: "...fuck you!"
God is not as good as man. Humanity originally thought that after the Green Light Civilization ran away, it would also take away the unknown fleet. But the damn Green Light Civilization actually wanted to explode the star and the sun!
Yu Yifeng felt his throat was dry and itchy, and swallowed hard.
At this time, he was not the only one on the observatory, but there were also a large number of scientists and government personnel. They were all standing in a daze, as if they couldn't believe what they were seeing.
Green Light Civilization...is it crazy?
But this letter is not over yet... Yu Yifeng forced himself to be patient and continued reading.
At the end, the Green Lantern people "begged" the new human civilization to agree to their plan and not to shoot down their spaceship... In order to make up for their losses here, they are willing to give humans 0.3 units of "anti-entropic field aggregation particles"?
What the hell is this?
If the green light civilization can observe the explosion of this star, it will give humans an additional 0.7 units of "anti-entropic field aggregation particles" in the future. The premise is that the new human civilization can reach one of their colonial planets
, they will definitely not default on their debts...
There is a bunch of flattering text at the end, and finally there is a star road map, marking the location of their colonial planets.
Yu Yifeng simply didn't know what to say. Behind him were a bunch of yells such as "Fuck!" and "Fuck!"
They directly ignored what "anti-entropic field aggregation particles" were, and focused all their attention on the destruction of the sun!
The damn green light people will run away if they run away, and they will destroy their sun!
Everyone was shaking with anger, they must stop this from happening! Definitely!
Soon, Yu Yifeng held another meeting...
"We're going to nuke it!"
Xu Yunjin was furious and roared crazily. His face was red and he was in a crazy state where adrenaline hormones were secreted rapidly. He had never been so angry and excited in his life. The other people in the conference room were also like this, in an extremely crazy state.
In status.
What is the concept of a solar explosion? It is equivalent to a supernova explosion! Even if it is not, it is not much different. This is the most violent natural disaster in the universe. It can at least swallow up everything within one light-year!
Yes, whether it is Mars, Saturn, Pluto, or the distant Oort Nebula, they all become interstellar dust.
What will human beings look like by then? Naturally, they will turn into ashes, or there will not even be any dust left... Mars is really too close, too close, too close!
Now no one is thinking about the super fleet of the unknown civilization. The most critical thing at hand is... to knock down the spaceship of the Green Light Civilization!
How to fight? Naturally, we use mankind’s most powerful weapon: nuclear bombs.
"Fight it down, we must fight it down!"
A trillion-ton tetrahydrogen nuclear bomb is the ultimate pride of mankind! This nuclear bomb, which is as tall as a ten-story house, is the pinnacle of mankind's current work, and is a thousand times more powerful than previous helium-3 nuclear bombs.
Now no one is considering the cost issue at all, everyone just wants to knock down this damn spaceship first!
Although its yield can be made larger, humans do not have rockets powerful enough to propel it. A quadrahydrogen nuclear bomb with a yield of one trillion tons is already the limit of its propulsion power.
After some calculations by the scientists, Yu Yifeng solemnly said: "We probably only have one chance, because this alien spacecraft flies so fast. It will take about three to four months for it to sail."
85 astronomical units, this speed is beyond the reach of even our rockets."
"Once we miss it, we will completely lose the opportunity to attack!"
It is easier to use high-speed objects to intercept low-speed objects, but to use low-speed objects to intercept high-speed objects, the opportunity is often once, if you miss it, there will be no more...
