Deep Space Fleet

As time passed and all preparations were completed, "Kunlun Mountain" suddenly fired a small electromagnetic cannon. This shell flickered forward with blue light ... When it reached the intended location, it looked like a firefly Just explode gently.

The scientific name of this electromagnetic gun is ... "supergravity cannon". It sounds very cool. In fact, in addition to its kinetic energy, it is not too aggressive.

Its cost is also extremely expensive. The composition of the shell is composed of low-temperature condensate and some special subatoms. It can mimic the superfluid phenomenon in condensed matter physics, build a graviton superfluid, and realize the gravitational short circuit in some areas.

This gravitational short circuit will cause the cosmic strings that were in equilibrium to oscillate slightly.

Immediately afterwards, the gravitational force inherent in the cosmic string itself will be re-energized!

Just at this moment, a very strange gravitational field was created!

The Kunlun Mountain itself, and the spacecraft hanging around it, were like a kite with a broken line. They were all sucked in by the huge gravitational force generated by the front, and they started to accelerate madly.

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

Even though this kind of exercise has been tried many times in the past few years, there should not be too many problems in theory, but everyone can't help but feel a little nervous.

"Report the captain. The gravitational fluctuations produced are 1.4% of the expected deviation, which is acceptable!"

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

Zhang Yuan sat in the captain's room and spoke aloud: "Always pay attention to the course of the spacecraft and keep in the right direction."

"Watch out for meteorites that might be attracted around."

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

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

"10, 9, 8, 7 ..."

If you are an uninformed person, you will feel very strange. Under such a large acceleration, the people in the spaceship don't feel much, and they have not been crushed into a pile of meatloaf!

Even trained astronauts can only withstand accelerations of about 10 g, and now they have at least 20 g!

Moreover, everything is still in the same state as usual ... The non-living area is still in a state of weightlessness, and the people inside the living area are still living normally without any feeling.

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

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

When Einstein proposed the special theory of relativity, he had such thought experiments.

What happens if a person falls from a height?

Ignoring air resistance, human inertia and gravitational mass will cancel out, making people feel completely weightless, as if there is no gravity at all. There is not much difference between this accelerated fall and zero gravity.

The zero-gravity environment is exactly the playground of the special theory of relativity. It promotes the equivalence between the mass of inertia and gravity as a basic principle. Under this premise, the birth of the special theory of relativity.

Therefore, using gravitational acceleration, even if there is such a large overload, the spacecraft will still not have obvious elastic deformation, and the passengers inside will not feel anything. This is its true superiority!

Otherwise, if you use the engine to push, even if you can use the acceleration of 200 meters per second square seconds, Kunlun Mountain has long become a pile of space trash!

"3, 2, 1, 0!"

With the end of the countdown, all of a sudden, the source of gravity returned to calm and all the spacecraft's overloads disappeared all at once.

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

Almost doubled!

This is the way to use the cosmic string to advance ... gravity acceleration!

There was a small cheer in the control room.

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

If it was placed in the past, it would require massive amounts of nuclear fuel for propulsion to reach this speed, but now, only a small cannonball can solve it.

Although the cost of this cannonball is high, it is not known how many times better than the cost of material resources and the efficiency of the advancement compared with the consumption of massive material resources.

"The cosmic string, really the highway in the universe. If you find it, it can be easily used. If you can't find it ... 唉, especially those civilizations far from the cosmic string, you can only say that luck is too bad, including the original Earth ~ www.readwn.com ~ Is this a screening ... "

He said something silently in his heart, followed by a loud voice: "Each queue, the auxiliary engine power system is enabled, the forward direction of the queue is adjusted, and the state of the spacecraft is reported."

He said to his assistant again: "Collect the data of this gravitational acceleration and observe the surrounding environment. If there are no problems, the next gravitational acceleration will start in 15 days."

"understood."

In fact, human beings are fully capable of inducing greater gravitational fluctuations, and even using the cosmic strings to generate a huge gravitational force like the sun is not a problem!

Although only a few tenths of a second ...

But triggering too much gravitation, on the contrary, will generate great risks.

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

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

The second point is that this is inside the planetary system. Although large gravity can speed up the speed of the spacecraft, it will also disrupt the operation of the planet itself.

Maybe some meteorites in the surrounding area were quickly attracted. When the spacecraft was hit by the time, it was worth more.

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

So there are so many frigates near Kunlun Mountain, on the one hand to enhance military strength, and on the other hand to prevent possible meteorite, even fist-sized ones will be found in time and then melted with laser weapons.
