Chapter 311

As time went by and all the preparations were completed, "Kunlun Mountain" suddenly launched a small electromagnetic gun, which flashed blue light and rushed forward After arriving at a given place, it explodes like a firefly.

The scientific name of this electromagnetic gun is "Super graviton gun" sounds very cool. In fact, besides its own kinetic energy, it is not very aggressive.

Its cost is also very expensive. The composition of the shell is composed of low-temperature condensed matter and some special sub atoms. It can imitate the superfluid phenomenon in condensed matter physics and construct a kind of graviton superfluid to realize the gravitational short circuit in some regions.

This gravitational short circuit will make the cosmic string in equilibrium slightly vibrate.

Then, the gravitational force of the cosmic string itself will be re excited!

At this moment, a very strange gravitational field was produced!

The Kunlun Mountain itself and the surrounding spaceships are like broken kites. They are all attracted by the huge gravity in front of them, and Qisen begins to accelerate wildly.

All the staff are also nervous, the parameters on the screen are constantly changing, and the closer to the gravitational node, the faster the acceleration of the spacecraft will be.

Even though this kind of exercise has been tried many times in the past few years, there won't be too many problems in theory, but we still can't stop being a little nervous.

"Report to the captain, the deviation between the generated gravitational wave and the predicted value is 1.4%, which is within the acceptable range!"

"There is a certain gravity difference between the bow and stern of Kunlun Mountain, which is increasing. The current value is 60909.3 Newton! All parameters are normal and all components are online! "

Sitting in the captain's room, Zhang Yuan said in a loud voice: "always pay attention to the course of the spacecraft and keep the direction correct."

"Pay attention to the meteorites that may be attracted around."

"The current acceleration of the spacecraft, 199.8 meters per second, is continuously increasing 200，201，202……”

"The first gravitational acceleration, expected countdown..."

“10，9，8，7……”

If you don't know, you will feel very strange. Under such a large acceleration, the people in the spaceship didn't feel too much, and they were not pressed into a piece of meat cake!

Even the astronauts who have been trained for a long time can only bear the acceleration of about 10 g, but now there are at least 20 g!

Even, everything is still in the same state as usual People in non living areas are still weightless, while people in living areas still live normally without any feeling.

This is because, at present, this phenomenon is similar to free fall.

Gravity is a kind of macro force, which can act on every atom of the spaceship or human body almost evenly. Therefore, if it is not for the existence of reaction force, human beings can hardly feel the effect of gravity.

Einstein had this kind of thought experiment when he put forward the special theory of relativity.

What happens if a person falls from a height?

Ignoring the air resistance, people's inertia and gravitational mass will counteract, making people feel that there is no weight at all, just like there is no gravity at all. There is not much difference between this accelerated fall and zero gravity state.

Zero gravity environment is exactly the playground of special relativity, which promotes the equivalence between inertial mass and gravity mass as a basic principle. Under this premise, special relativity was born.

So, using gravitational acceleration, even if it is such a large overload, the spacecraft will still not appear obvious elastic deformation, and the passengers inside will not feel much, which is its real advantage!

Otherwise, using the engine to push, even if you can use 200 meters of acceleration every second, Kunlun mountain will become a pile of space garbage long ago!

“3、2、1、0！”

With the end of the countdown, all of a sudden, the whole source of gravity has returned to calm, all of a sudden, the overload of all spacecraft disappeared.

But the disappearance of acceleration does not mean the disappearance of kinetic energy. The whole speed has increased from 25 KPS to 40 KPS!

Almost doubled!

That's how we use cosmic strings to propel Gravitational acceleration!

There was a little cheer in the control room.

Zhang Yuan breathed a sigh of relief and took a look at the data on the screen. This acceleration is very successful. At present, the speed of Kunlun Mountain is as high as 41.22km/s.

In the past, a huge amount of nuclear fuel was needed for propulsion to reach this speed, but now, only a small shell can solve the problem.

Although the cost of this shell is high, but compared with the consumption of massive material resources to promote, whether it is cost or propulsion efficiency, we do not know how many times superior.

"Cosmic string, as expected, is the highway in the universe. If you find it, you can use it easily. If you can't find it Alas, especially those civilizations far away from the cosmic string, we can only say that their luck is too bad, including the original earth. Is this a screening... "He murmured in his heart, and then said in a high voice: "each queue, activate the auxiliary engine power system, adjust the forward direction of the queue, and report the operation status of the spacecraft."

He also said to his assistant: "collect the data of this gravitational acceleration and observe the surrounding environment. If there is no problem, the next gravitational acceleration will start in 15 days."

"I see."

In fact, human beings have the ability to cause greater gravitational waves. Even using cosmic strings to generate a huge gravitational force like the sun is not a problem!

Although only a few seconds

But too much gravitation, on the contrary, will have a great risk.

The first is that the acceleration is too large, causing damage to the spacecraft. Although gravity will act on every atom almost evenly, its size is inversely proportional to the second power of the distance. In other words, the force on the bow and stern of the Kunlun Mountain is different.

If the gravitational difference is too big, it will pull the spacecraft apart like noodles. It's the same principle that black holes attract matter.

Second, it's inside the planetary system. Although gravity can speed up the spacecraft, it can also disrupt the operation of the planet itself.

Maybe some meteorites in the surrounding area will be quickly attracted and hit the spaceship at that time, but the gain is not worth the loss.

What's more, there is a human base in the rear, so there is no need to use gravity to disturb the normal orbit of the planet.

That's why so many frigates are equipped near "Kunlun Mountain". On the one hand, they are to enhance military strength, and on the other hand, they are to prevent possible approaching meteorites. Even fist sized frigates will be found in time and then melted with laser weapons.
