Chapter 318

As time arrived and all preparations were completed, "Kunlun Mountain" suddenly launched a small electromagnetic gun, which flashed blue light and rushed forward... After reaching the established place, it exploded gently like a firefly.

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

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

This gravitational short circuit will slightly vibrate the cosmic string that was originally in equilibrium.

Then, the gravity contained in the cosmic string itself will be re excited!

At this moment, a very strange gravitational field came into being!

The Kunlun Mountain itself and the spacecraft attached around it were like a broken kite. They were all sucked by the huge gravity suddenly generated in front, and Qi Sen began to accelerate frantically.

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

Even though such exercises have been tried many times in the past few years, there will not be too many problems in theory, but we still can't help being a little nervous.

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

"There is a certain gravitational difference between the bow and stern of Kunlun mountain. This gravitational difference is increasing. At present, the value is 60909.3 Newton! All parameters are normal and all components are online! "

Zhang Yuan sat in the captain's room and said loudly, "always pay attention to the route of the spacecraft and keep the direction correct."

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

"The current acceleration of the spacecraft, 199.8 meters per second, is increasing... 200201202..."

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

“10，9，8，7……”

It would be very strange for people who don't know. Under such a large acceleration, the people in the spacecraft don't feel much and haven't been pressed into a lump of meat pie!

Even well-trained astronauts can only withstand acceleration of about 10 g, but now there are at least 20 g!

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

This is because, at present, this phenomenon is similar to that of a free falling body.

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

Einstein had such an ideological 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 offset, making people feel that there is no weight at all, as if there is no gravity at all. This accelerated fall is not much different from the 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.

Therefore, using gravitational acceleration, even if it is such a large overload, the spacecraft will still not have obvious elastic deformation, and the passengers inside don't feel much. This is its real advantage!

Otherwise, using the engine to push, even if you can use the acceleration of 200 meters per second, it will turn Kunlun mountain into a pile of space garbage!

“3、2、1、0！”

With the end of the whole countdown, suddenly, the whole gravitational source returned to calm, and the overload of all spacecraft disappeared all at once.

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

Almost doubled!

This is the way to use cosmic strings... Gravitational acceleration!

There was a little cheering in the control room.

Zhang Yuan breathed a sigh of relief and glanced at the data on the screen. This acceleration was very successful. At present, the speed of Kunlun Mountain is as high as 41.22kms.

In the past, a large amount of nuclear fuel was needed for propulsion to reach this speed, but now it can be solved with a small shell.

Although the cost of this shell is high, it is much better than consuming massive material resources to promote, both in cost and efficiency.

"Cosmic string, sure enough, the highway in the universe. It's easy to use if you find it. If you can't find it... Alas, especially those civilizations far away from the cosmic string, you can only say that your luck is too bad, including the original earth. Is this a screening... "

He murmured a sentence in his heart, followed by a high voice: "each queue, enable 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 are fully capable of causing greater gravitational fluctuations. Even using cosmic strings to produce huge gravity like the sun is not a problem!

Although only a few tenths of a second

But if it causes too much gravity, it will have a great risk.

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

If the gravitational difference is too large, the spacecraft will be pulled apart like noodles. This is the same principle that black holes attract matter.

Second, this is inside the planetary system. Although gravity can speed up the spacecraft rapidly, it will also disrupt the operation of the planet itself.

Maybe some meteorites around will be quickly attracted, and hit the spacecraft at that time, but the gain is not worth the loss.

Moreover, there is a human base in the rear, so there is no need to disturb the normal orbit of the planet with great gravity.

Therefore, so many frigates are equipped near the "Kunlun Mountain". On the one hand, it is to improve military strength, on the other hand, it is to prevent meteorites that may be close. Even fist sized ones will be found in time, and then melted with laser weapons.
