Wandering Spaceship in Deep Space Chapter 311: Supergravity subcannon

As time passed and all preparations were completed, "Kunlun Mountain" suddenly launched a small electromagnetic cannon, which flashed blue light and sprinted forward... After reaching the predetermined location, It explodes gently like a firefly.

The scientific name of this electromagnetic gun is called..."Supergravity Sub-Cannon", which sounds very cool, but in fact, apart from its own kinetic energy, it is not very offensive.

Its cost is also very expensive. The composition of the shells is composed of low-temperature condensed matter and some special subatoms, which can imitate the superfluid phenomenon in condensed matter physics, construct a kind of graviton superfluid, and realize the gravitational force of some areas. Short circuit.

This kind of gravitational short circuit will slightly oscillate the cosmic string that was originally in equilibrium.

Immediately afterwards, the gravitation contained in the cosmic string itself will be re-energized!

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

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

All the staff are also nervous, the various parameters on the screen are constantly changing, and the closer to that 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 everyone can't help but feel a little nervous.

"Report to the captain that the deviation of the 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. The current value is 60909.3 Newtons! All parameters are normal and all components are online!"

Zhang Yuan sits in the captain's room and speaks loudly: "Always pay attention to the flight path of the spacecraft and keep the direction correct."

"Watch out for meteorites that may be attracted to the surrounding area."

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

"The first gravitational acceleration is expected to count down..."

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

If you are an unknowing person, you will find it very strange. Under such a large acceleration, the people in the spacecraft will not feel much, and they have not been crushed into a meatloaf!

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

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

This is because the current phenomenon is similar to free fall.

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

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

What happens if a person falls from a height?

Ignore 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 the zero gravity state.

Zero-gravity environment is precisely the playground of special relativity, which raises the equivalence between inertial mass and gravitational mass as a basic principle. Under this premise, the special theory of relativity was born.

So, using gravitational acceleration, even with such a large overload, the spacecraft will still not show 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 an acceleration of 200 meters per second, it will turn Kunlun Mountain into a pile of space junk!

"3, 2, 1, 0!"

As the entire countdown ended, suddenly, the entire gravity source returned to calm again, and all of the spacecraft's overload disappeared.

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

Almost doubled!

This is how the cosmic string is used to advance...gravitational acceleration!

There was a small cheer in the control room.

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

If you put it in the past, it would take a huge amount of nuclear fuel for propulsion to reach this speed, but now, it only needs a small cannonball to solve it.

Although the cost of this cannonball is high, it is not known how many times it is superior in terms of cost or propulsion efficiency compared to consuming massive amounts of material resources.

"The cosmic string is indeed a highway in the universe. If you find it, you can use it easily. If you can’t find it... alas, especially those civilizations that are far away from the cosmic string, you can only say that luck is too bad. , Including the original Earth~IndoMTL.com~ Is this a screening..."

He muttered silently in his heart, and then said loudly: "Each queue, activate the auxiliary engine power system, adjust the forward direction of the queue, and report the operational status of the spacecraft."

He might overdo it and say 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."

"Understood."

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

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

But if it causes too much gravitation, it will produce a lot of risk.

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

If this gravitational difference is too big, it will tear the spaceship alive like noodles. This is the same principle that black holes attract matter.

The second point, this is inside the planetary system. Although the great gravity can make the spacecraft speed up quickly, it will also disrupt the planet itself.

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

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

That’s why there are so many frigates around "Kunlun Mountain". On the one hand, it is to enhance military strength, and on the other hand, it is to prevent meteorites that may approach. melt.
