Can gravity be shielded? If gravitational waves can be shielded like electromagnetic waves, is there an anti-gravity force?

This is a very important scientific question for interstellar civilization. Ｘ

According to relevant theories, gravity is not an over-distance effect, it also needs a medium to be able to propagate at the speed of light in space, and the medium of transmission is called graviton.

If these gravitons are taken away, is the gravitational force blocked? Just like light, if you block a photon with a wooden board, it will be difficult for the light to propagate, what can isolate the graviton?

The manipulation of gravitons has always been a key research project of the green light civilization. They know that anti-gravity technology is a path to a stronger civilization.

If the nature of gravity is indeed graviton, it is possible to construct a superfluid with a graviton modeled after the "superflow phenomenon" in condensed matter. By surrounding the superfluid around a finite area to be shielded, the superfluid can short-circuit the graviton flow through this area under normal circumstances, thus achieving a localized shielding effect.

This is a gravitational shield in the true sense of the word, which can confine the "gravitational force" to a certain area, and even manipulate it to a certain extent!

The Green Light Man speculated that this is the principle of the related device of the neutron star fragment. As long as the switch is pressed, the external gravitational force disappears, which is really amazing.

However, this true anti-gravity technology is really too difficult, and for thousands of years, green light scientists have achieved nothing in this area, and they really feel the limitations of theory.

They even suspected that the technology tree of the Green Light Civilization had been misled by this neutron star fragment, and this kind of god-like technology was not something that their current science and technology could do!

The anti-gravity technology of other civilizations may not be this method of drawing money from the bottom of the kettle at all, but other simpler technologies: ultra-high voltage electric fields and spin polarization, for example.

By the end of the second emergency session, the insane radicals had already taken up the overwhelming majority.

The Greenlight people were determined to abandon the neutron star fragment and their main ship once and for all...... Give their enemies a blow!

According to the plan that was made, the Greenlight people prepared a spare space shuttle with a length of about ten kilometers, and they will use this small space shuttle to return to their home planet. Because the space shuttle has a limited volume, most of the crew will hide in the hibernation chamber and sleep, and only a small number of operators will be active and responsible for the control of the spacecraft.

This is an extremely dangerous act, like abandoning an aircraft carrier in the middle of the ocean and crossing the ocean in a small motorboat. But this is how long the brains of the green light people are, such revenge is definitely in line with the requirements of "etiquette", any refutation is powerless, even if it is dangerous, it is worth doing.

And their original main ship will continue to stay in the solar system as bait! The intelligent program is responsible for timing and giving the enemy superfleet another hard ...... when it approaches the solar system

Although this super fleet is powerful, it is still far from the super-civilization of the gods, and they definitely can't afford a supernova explosion.

At the same time, the Greenlight people are very confident that their precious gifts will satisfy the "new human civilization" and thus cooperate with their plans...... Because they're bleeding profusely!

More than a dozen hours later, Noah's gravitational-wave telescope suddenly observed a large weakening of the dot representing the green light spacecraft, and then moved slowly. At the same time, people received an urgent message, which was sent by the Green Light Civilization.

"Gravitational pull has decreased? Are they leaving? ”

Yu Yifeng's heart moved slightly, and he immediately clicked on this information, thinking that he was finally going to send these plague gods away.

At the very beginning of this message, the Green Light Civilization first praised the generosity of the "New Human Civilization", and they were grateful to the Green Light Civilization. And all of them have already left on the spare space shuttle, saying goodbye to humanity......

Seeing this, Yu Yifeng felt slightly puzzled, isn't the other party's main ship still there, why has the other party already run away? Can't you abandon the main ship? Could humans be able to pick up garbage again?

Yu Yifeng's heart was inexplicably moved.

Then, the Greenlight people turned around and scolded the "destroyer civilization" that brought them unprovoked war, as well as the undying hatred......

Okay, okay, humans have already guessed most of these things, just run, don't talk big, there's nothing to be ashamed of...... This is what Yu Yifeng thinks in his heart.

It's normal to run if you can't beat it.

Looking at it any further, his face suddenly changed, and his temples jumped suddenly, as if he couldn't believe it. This content is so surprising and shocking! He bit his lip so hard that a bloody smell instantly appeared in his mouth, and he was only able to wake up a little under the stimulation of intense pain.

Although he has been stimulated a lot in the past few days, and his psychological tolerance has improved a lot, Yu Yifeng still can't help but want to scold his mother at this moment: "...... Fuck it! ”

Human beings are not as good as heaven, and human beings originally thought that after the green light civilization ran away, they would also take the unknown fleet with them. But this damn green-light civilization is going to detonate the stars and detonate the sun!

Yu Yifeng felt that his throat was dry and itchy, and he swallowed hard.

At this time, he was not the only one on the observatory, but also a large number of scientists and government officials. They all stood in a daze, as if they couldn't believe what they were seeing.

Green Light Civilization ...... Crazy?

But the letter is not over yet...... Yu Yifeng forcibly resisted and continued to look down.

In the end, the Green Light "pleaded" with the new human civilization to agree to their plan and not shoot down their ship...... To compensate for their loss here, they are willing to give away 0.3 units of "anti-entropy field aggregate particles" to humans?

What the hell is this?

If the green light civilization can observe the explosion of this star, it will also give humans an additional 0.7 units of "anti-entropy field aggregation particles" in the future. The premise is that the new human civilization can run to one of their colonized planets, and they will definitely not be ruined by then......

There is also a bunch of flattering text at the back, and finally a chart of star paths marking the location of their colonized planets.

Yu Yifeng didn't know what to say, and behind him was a bunch of "**! "Grass!" Something like that.

They simply ignore what the "anti-entropy field aggregate particle" is, and all their attention is focused on the destruction of the sun!

Damn the Green Light Man, if you run, you will run, and you will destroy their sun!

Everyone is trembling with anger, and they must stop this from happening! Certain!

Soon, Yu Yifeng held a meeting again......

"We're going to blow it up with a nuclear bomb!"

Xu Yunjin was in a hurry, roaring wildly, his face was flushed, and he was in a state of madness with rapid secretion of adrenal hormones. He had never been so angry and excited in his life, and so were the others in the room, in a state of extreme madness.

What is the concept of a solar explosion? Equivalent to a supernova explosion! If not much, this is the most violent natural disaster in the universe, and it can swallow up everything within a light-year!

Yes, whether it is Mars, Saturn or Pluto, or the distant Oort Nebula, all become interstellar dust.

What will become of humanity then? Naturally, it will be ashes, or even a speck of dust...... Mars, it's too close, it's too close!

Now no one thinks about the superfleet of unknown civilizations, and the most important thing in front of us is ...... Knock down the spaceship of the Green Light Civilization!

How to fight? Nature is with the strongest weapon of mankind: the nuclear bomb.

"Knock it down, you must beat it down!"

A trillion-ton four-hydrogen nuclear bomb is the ultimate pride of mankind! This nuclear bomb, which is the height of a ten-story house, is the pinnacle of mankind at present, and is a thousand times more powerful than the previous helium-3 nuclear bomb.

No one is thinking about the cost at all, everyone just wants to take the damn ship down first!

Although it can be made larger, however, humans do not have a rocket strong enough to propel it. The trillion-ton yield of the four-hydrogen nuclear bomb is already the limit of the propulsion.

After some calculations by the scientists, Yu Yifeng said solemnly: "We probably only have one chance, because this alien spacecraft is flying too fast. In about three to four months, it can travel 85 astronomical units, a speed that our rockets can't reach. ”

"If we miss it, we will completely lose the opportunity to attack!"

It is relatively simple to intercept a low-speed object with a high-speed object, but to intercept a high-speed object with a low-speed object, the opportunity is often so once, and if you miss it, there will be no more......

Humanity must be prepared! r
