As the time came and all the preparations were completed, the "Kunlun Mountain" suddenly launched a small electromagnetic cannon, which flashed blue and rushed forward...... When you arrive at the established location, it gently explodes like a firefly.

The scientific name of this electromagnetic cannon is called ...... "super graviton cannon", which sounds very cool, but in fact it is not very aggressive except for its own kinetic energy.

It is also extremely expensive, and the composition of the shell is composed of low-temperature condensed matter and some special subatoms, which can imitate the superflow phenomenon in condensed matter physics, construct a graviton superfluid, and realize gravitational short circuits in some areas.

This gravitational short circuit causes the cosmic strings, which are originally in equilibrium, to oscillate slightly.

Immediately afterward, the gravitational pull of the cosmic string itself will be re-energized!

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

The main body of Kunlun Mountain, as well as the spaceships attached around it, were like kites with broken strings, all of which were sucked by the huge gravitational force suddenly generated in front of them, and Qi Sensen began to accelerate wildly.

All the staff members were also nervous, the parameters on the screen were constantly changing, and the closer to that gravitational node, the faster the acceleration of the spacecraft would be.

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

"Report to the captain that the gravitational fluctuations generated are 1.4% off from the projection, which is within an acceptable range!"

"There is a certain gravitational difference between the bow and stern of the Kunlun Mountain, and this gravitational difference is increasing, and the current value is 60909.3 Newtons! All parameters are normal, all components are online! ”

Zhang Yuan sat in the captain's room and said in a loud voice: "Always pay attention to the route of the spaceship and keep the direction correct." ”

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

"The spacecraft's current acceleration, 199.8 meters per square second, is continuously increasing...... 200，201，202……”

"First gravitational acceleration, expected countdown ......"

“10，9，8，7……”

If you are unaware, you will feel very strange, under such a large acceleration, the people in the spaceship actually don't feel much, and they are not crushed into a lump of meatloaf!

Even trained astronauts can only withstand an acceleration of about 10 g, and now there are at least 20 g!

Even, everything is still in the same state as usual...... The non-living area is still in a state of weightlessness, while the people inside the living area are still living normally and do not feel anything.

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

Gravitational force is a macroscopic force that can act almost evenly on every atom of a spaceship or human body, so that if it were not for the presence of a reaction force, human beings would hardly feel the effect of gravity.

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

What happens if a person falls from a height?

Ignoring the air resistance, the inertia and gravitational mass of the person will cancel out, making the person feel completely weightless, as if there is no gravity at all, and this accelerated fall is not much different from the state of zero gravity.

The zero-gravity environment is precisely the playground of special relativity, and it is under this premise that the equivalence between inertial mass and gravitational mass is elevated to a basic principle, and the special theory of relativity is born.

Therefore, using gravitational acceleration, even if it is such a large overload, the spacecraft will still not show obvious elastic deformation, and the passengers inside will not feel anything, this is its real superiority!

Otherwise, even if the engine can be propulsed, even if the acceleration of 200 meters per square second can be used, Kunlun Mountain will have already become a pile of space junk!

“3、2、1、0！”

As the whole countdown ended, suddenly, the entire gravitational source returned to calm, and all the ship's overloads disappeared at once.

But the disappearance of acceleration does not mean that the kinetic energy has disappeared, and the entire speed has risen from the original 25 kilometers per second to 40 kilometers per second!

Almost doubled!

This is how the cosmic strings are used...... Gravitational acceleration!

There was a small cheer in the control room.

Zhang Yuan breathed a sigh of relief, glanced at the data on the screen, and this time the acceleration was quite successful, and the current speed of Kunlun Mountain was as high as 41.22km/s.

In the past, it would have required a huge amount of nuclear fuel for propulsion to reach this speed, but now, just a small artillery shell is all it takes.

Although the cost of this shell is high, compared with the consumption of massive material resources to propulsion, whether it is cost or propulsion efficiency, I don't know how many times superior.

"Cosmic strings, sure enough, the highway in the universe. If you find it, you can use it, but if you can't find it...... Alas, especially those civilizations that are far from the cosmic strings, can only be said to have had too bad luck, including the original Earth. Is this a screening......"

He muttered silently in his heart, and then said in a loud voice: "Each queue, activate the auxiliary engine power system, adjust the direction of the queue, and report the operation status of the spacecraft." ”

Or he turned around and said to his assistant: "Collect the data of this gravitational acceleration, observe the surrounding environment, and if there is no problem, the next gravitational acceleration will start in 15 days." ”

"Understood."

In fact, human beings are fully capable of causing even greater gravitational fluctuations, and even using the cosmic strings to produce a huge gravitational force like the sun!

Although it is only a few tenths of a second......

But if you cause too much gravity, there will be a lot of risk.

The first is that the acceleration is too great, causing damage to the spacecraft, and although the gravitational force will act almost evenly on every atom, its magnitude is inversely proportional to the quadratic of the distance. In other words, the force on the bow and stern of the Kunlun Mountain is different.

If this gravitational difference is too large, it will pull the spaceship alive like noodles. This is the same principle as a black hole attracts matter.

The second point is that this is inside the planetary system, and although the gravitational pull can quickly increase the speed of the spacecraft, it can also disturb the operation of the planet itself.

Maybe some meteorites in the surrounding area will be quickly attracted to it, and when the time comes, it will be more than worth the loss when it hits the spacecraft.

What's more, there is also the presence of a human base in the rear, and there is no need to disturb the normal orbit of the planet with a large gravitational pull.

That's why there are so many frigates near the "Kunlun Mountain", on the one hand, to improve military strength, and on the other hand, to prevent meteorites that may be approaching, even if they are the size of a fist, they will be detected in time and then melted with laser weapons.
