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 series of complex codes began to flow rapidly, like the data flow in the galaxy, continuously analyzing the surrounding environment.

Phew~

As the drone's carrying speed increases, it begins 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, emitting a smell of being burned by high temperature.

Soon, the drone could no longer stand it.

It fell to the ground like a weightless comet. 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 disgustingly bad. I can confirm that this place is definitely not a breeding ground for 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——]

"Hoo~"

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 in 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."

While Xia Xiu was talking, he stretched out his right hand to hold it empty, and while he was holding it empty, the figure of [Sisyphus] floated out from his body.

"Everything·Vector Authority——"

Through authority, the fourth sword holder in 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 the gravitational lensing effect can reveal the mass distribution of foreground objects.

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

[OK.]

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

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

This chapter is not over yet, please click on the next page to continue reading! As for the tidal force, it goes without saying any more. 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, the closer the place is, the stronger the gravity will be. This causes the part of Terra closer to the moon (or sun) to have a greater gravitational pull than the part further away.

The gravitational effect of the moon on Terra's water bodies causes periodic rise and fall of the ocean surface, forming the tidal phenomenon 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 celestial bodies, that is, precession and nutation.

Precession is a change in the orbit of a celestial body's axis of rotation, which has the effect of causing the axis to trace a conical path through space.

Tyra's precession (or precession) is mainly caused by the uneven tidal force of the sun and moon on its equatorial bulge. The tidal force will cause a continuous torque on the celestial body, causing the direction of its rotation axis to slowly change;

Nutation is the swing 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).

Periods match.

So the natural result is 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 effect 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 countries that are capable of conducting starry sky experiments on Terra through the Laser Lunar Ranging Experiment, which measures the round-trip time of laser pulses launched from Terra to a reflector on the moon.

But this is not a major matter that humans need to worry about. When Terra and the Moon divorce, humans will not know if they will still be there at that time.

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 using 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 a terrestrial 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.
