Extraordinary pedigree

In the vast vacuum world, the ice and snow particles all over the sky reflect the starlight, like floating pearls in the universe.

In this cold and silent environment, the creation of Ohm Messiah activated its plasma propulsion system and rose into the vast night sky.

The plasma engine of the drone roared, ejecting a blue flame, which was a wake composed of high-speed ions. It drew a bright blue trajectory in the vacuum. In the center of the fuselage, the drone The "eye" - a delicately designed circular sensor, suddenly lights up with cold blue light between the coldness of machinery and the silence of the universe.

Inside the sensor, a string of complex codes began to flow rapidly, like a data stream in the galaxy, continuously analyzing the surrounding environment.

Phew~

As the drone's delivery speed increased, it began to enter overheating mode.

The matte coating on the surface of the fuselage, which was originally used to hide it in the night, now begins to become hot, as if it has been baked by the stars, exuding a smell of being burned by high temperature.

Soon, the drones couldn't stand it anymore.

It fell to the ground like a weightless comet, and with a "peng" sound, the drone hit the thick ice, and then his surroundings began to flash with rapid blue data color blocks, accompanied by With a popping sound, the drone completely disappeared in this world of ice and snow.

During the scanning process, the unstable magnetic field generated by the planet directly exploded the drone in overload mode.

On the other side, Xia Xiu, who was on the ship, had already finished reading the superficial data analyzed by [Adam].

"The environment of this planet is really disgusting. I can confirm that this place is definitely not a hotbed of life." The blond young man couldn't help but sigh.

As Xia Xiu spoke, the hot breath exhaled from his mouth and nose condensed into wisps of white mist in the cold environment, rising slowly like soft smoke clouds, and then quietly dissipated in the cold air.

To suit the occasion, he specially projected a set of winter clothes from [Private Customization] to put on his body, and also put on a thick white winter hat on his head.

[This planet’s galaxy environment once experienced a crisis sequence-level physics doomsday scenario. Based on the orbital dynamic data and magnetic field changes detected by the drone, as well as the supercomputer detection of [Torino Type I], it can basically be concluded that The nebula structure above is from a devastating planetary disaster——]

[With perfect prosthetic eyes, you should be able to quickly detect the nature of the nebula above——]

"Huh~"

Listening to [Adam]'s report, Xia Xiu stretched out his hands and blew a breath of hot air. His golden eyes carefully looked at the colorful nebula above.

As a graduate of Luyuan and a high-ranking angel in heaven, through the many physical data transmitted by the drone just now, [Adam] didn't need to say anything, he also knew what the nebula above was made of.

“The gas lost by gas giant stars initially forms unique nebula shapes. These lost gases affect the observable spectral characteristics of the night sky, and the movement of gas clouds in space and the action of light will form variable patterns and structures. "

At this moment, Xia Xiu's eyes had turned as white as snow. Through the [Perfect Prosthetic Eyes], he quickly saw through the colorful nebula and observed the gas giant planet above that was so close to the ice and snow world.

It is showing a distorted and deformed change at the moment. It is not spherical in the traditional sense, but a weird structure with concave and irregular bulges. It looks like it has been slapped hard by something. After the stick, an irreversible deformation occurred.

"Although the gravity here is the same as Terra, there is a high probability that it is not its most original appearance."

As Xia Xiu spoke, he stretched out his right hand to hold it empty, and while he was holding it empty, the figure of [Sisyphus] floated out of him.

"Everything·Vector Authority——"

Through authority, the fourth sword holder of the Kingdom of Heaven quickly grabbed part of the mass, and a powerful gravitational field began to be constructed.

A strong gravitational field can bend light from the stars behind it, causing a lens effect.

Observing these effects through gravitational lensing can reveal the mass distribution of foreground objects.

"Adam, import the test module." Xia Xiu ordered.

[OK. ]

[Gravitational field measurement begins:

Gravity wave measurement and introduction

Tidal force analysis and introduction

·······]

By accurately measuring the satellite's trajectory deviation, the planet's gravitational field distribution can be measured. These data can reveal inhomogeneities in mass distribution, such as gravity anomalies due to heterogeneity in the internal structure.

Any event with extreme mass changes, such as a collision or core fragmentation, can produce gravity waves. By detecting these fluctuations, [Adam] can infer the characteristics of the events that produced them.

As for the tidal force, it goes without saying. As a force caused by uneven gravity, its most obvious manifestation is the tidal phenomenon on Terra.

This force is caused by differences in the distance between different parts of Terra and the moon or other celestial bodies.

Since gravity is a function of distance, closer locations experience stronger gravitational forces, which results in parts of Terra closer to the Moon (or Sun) experiencing a greater gravitational pull than those farther away.

The gravitational effect of the moon on Terra's water bodies causes periodic rise and fall of the ocean surface, forming the tides observed by humans.

Basically every location on Terra experiences two high tides and two low tides approximately every 24 hours.

Tidal forces also cause celestial bodies to experience distortion and deformation. The dynamic response of these distortions and deformations ultimately affects the rotation state and axis orientation of the celestial body, that is, precession and nutation.

Precession is a change in the orbit of a celestial body's axis of rotation, with the effect that the axis traces a cone-shaped path through space.

Terra's precession (or precession) is primarily caused by the uneven tidal forces of the Sun and Moon on its equatorial bulge, which exert a constant torque on the celestial body, causing the direction of its axis of rotation to slowly change; Nutation is the oscillation of a celestial body's axis of rotation, similar to the small circular motion of the axis of a spinning top.

Tidal locking is one of the important manifestations of tidal force. It is a common astrophysical phenomenon: the rotation period of a smaller celestial body (such as the moon) is related to its orbit around a larger celestial body (such as Terra). cycle matches.

So it follows naturally that the smaller body always shows the same face to the larger body, just as the moon always shows the same face to Terra.

Long-term tidal effects will redistribute energy and angular momentum among celestial bodies.

For example, the moon's tidal effects on Terra also caused changes in its own orbit.

Specifically, the moon is gradually moving away from Terra, about 3.8 centimeters per year. If the time scale is extended to the length of the planet, sooner or later the moon will "divorce and separate" from Terra.

This phenomenon has been confirmed by Terra's star-capable nations through the Laser Lunar Ranging Experiment, which measures the round-trip time of a laser pulse fired from Terra to a reflector on the Moon.

But this is not a big thing for humans to worry about. When Terra and Moon divorce, humans don't know if they are still there.

Moreover, according to the current version of Terra's environment, the Terrans are expected to be able to get some explosions before the two balls divorce, and release gorgeous fireworks in the universe with the sun.

[Measurement completed·Start data import——]

Huge data began to be calculated from Xia Xiu's brain. Relying on the powerful computing power of [Torino Type I], he can now defeat a super-cutting-edge composite technology team by himself.

"There are indeed abnormalities in precession and nutation. It can be basically inferred that this planet is an earth-like planet with a smaller mass than Terra, but its gravity is as heavy as Terra's; this has a lot to do with the gas giant planet above. , there is also a gravitational relationship between this planet and the gas giant planet, just like Terra and the moon, but the gravity of this gas giant planet on the mainland will be much greater than the gravity of the mainland on the gas giant planet, that is, here The planet is a satellite of the gas giant above."

"Just like the moon revolves around Terra, this planet initially revolved around the gas giant planet above. Now the measured tidal force, precession and nutation, and orbital movement of this planet are based on Look, the total angular momentum of this planetary system should not be like this initially. It was an accident that happened to the gas giant planet above, which affected the angular momentum distribution of the entire system."

Xia Xiu dispersed the authority in his hands, then stretched out his hand to rub his chin and began to think.

If the gas giant planet is the main star of the planet, then the total angular momentum of the system they constitute should be conserved, that is, orbit, tidal locking, precession, and nutation are all normal.

However, now the planet's various physical systems seem to have been ravaged.

The colorful nebulae above this ice and snow world have shrouded the entire planet. He knows what materials the nebulae above are. Those things are the interstellar materials (dust and gas) of the gas giant planets. In other words, they are the planets. "vomit".

Generally, when a planet spits out mass on a large scale, it means it explodes.

Yes, the core of the gas giant planet above is just several times smaller than Jupiter exploded.

The core fragmentation of a gas giant planet is different from the explosion of the entire planet, but it is indeed a serious internal change. If the core is "fractured," it will change the way the planet emits and reflects light, possibly causing changes in its brightness and visible characteristics.

The real unlucky thing is the nearby satellite. If the core of the gas giant planet is shattered, then the angular momentum it had before (rotation around its own axis and possible revolution around the central star) will be dispersed to all the stars in the process. of fragments.

If the fragments fly off in different directions, they will each carry a portion of the angular momentum of the original core.

Gas giant planets are the main stars of the ice and snow world, so the total angular momentum of the system they constitute will tend to be conserved. When the core of the gas giant planet is broken and the fragments fly in all directions, the angular momentum distribution of the entire system will also be affected, especially if There is quality loss out of the system.

Due to the core fragmentation event, in this case, according to the law of conservation of angular momentum, the orbital speed and distance of the planet must change to maintain the conservation of angular momentum in the system.

In layman's terms, it means that husband and wife are birds of the same forest, and they fly separately when disaster strikes.

The main star exploded, but not completely. It just spit out a lot of its own mass.

Then there will be insufficient mass to maintain the original orbit, so they start to throw each other away.

As for who dumped whom, that's a matter of opinion.

After all, the two balls were forced to separate due to material reasons, and their lives after separation were quite difficult.

The ice and snow world was directly thrown into a new orbit, and due to the fragmentation of the core of the gas giant planet, a large amount of material was ejected near the ice and snow world, and the ice and snow world that was forced to be pushed into a new orbit was itself placed in a place far away from the star. position and entered an extreme elliptical orbit.

The farther orbit causes the planet's surface temperature to drop significantly, causing a global climate disaster similar to the "nuclear winter" effect.

Moreover, its host star vomited a lot of things on it before the divorce, and these things were directly stuck on its face. A large amount of interstellar matter wrapped the ice and snow world, causing the absorption, scattering or reflection of the star's light, making the original The world of ice and snow with less light is even more desperate.

They have visually blocked the stars, creating conditions similar to "perpetual night."

"If it weren't for the previous events in the Country of Sea of ​​Fog, I could believe that this series of events was a coincidence, but in this situation..., I smell a familiar smell."

The only people he was familiar with who could play with a planet, apart from the one who ate everything and was unhappy, were those indescribable beings from the stars.

As well as a series of related experiments on the crisis sequence of the multi-powerful alliance in my hometown (Terra).

The more Xia Xiu thought about it, the more likely he felt that his idea was very likely.

During the time he was working in Terra, he had only one evaluation of the countries of Terra: they were a piece of shit together, but each of them was brilliant separately.

If we put aside the shackles of the [Crystal Sky], the stars, the four monarchs, the living gods, Alaya and other factors, the countries of Terra actually already have the ability to colonize the stars.

The current situation in Terra is: the Kingdom of Heaven is one pole, Edici, Daeva, Oletin, the Central Alliance and other countries are in a multi-powerful situation.

In a situation of one pole and multiple powers, Terra was equipped with a large number of [Reality Stabilizing Anchors] and [World Parameter Stabilizing Devices].

Even the moon has enjoyed the same treatment, and many devices have been inserted into its body.

The world parameters of Terra have long been turned into a weird planet by the manipulation of many powerful forces, and some of the knowledge of worldly physics has been manipulated into the back garden of thaumaturgic physics.

And multi-powerful alliances always like to do things that are beyond the safety threshold, such as the cooperation of stars to lead the party, the cyber flow of mechanical ascension, the escape of Terra, the great method of the Four Monarchs, Crimson Love, etc. A series of unfavorable operations.

I really agree with that sentence, if heaven had not given birth to me as a Terran, Terra would have been like a long night.

Wuwuwu~, my stomach hurts, and I still have to type, Wuwuwu~
