Half an hour later, the faster-than-light New Source appeared near a white dwarf.

Xinyuan immediately got busy, and began to probe the environment near the white dwarf, look for possible planets, calculate the gravitational range of the white dwarf, and if it finds planets or other small objects, determine the elemental composition of these objects.

Even if the shipboard computer of the Xinyuan has fantastic computing power, it will take a long time to complete such calculations.

Xia Zhuoyan and Ding Mengyao, who were engaged in detection, were so busy that others couldn't reach out if they wanted to help, so they could figure out the white dwarf on the screen together.

"Such a small white dwarf, it's quite bright!" Ji Xiaotong, who had just returned to the bridge, said in surprise, "It seems that the temperature of the white dwarf is not low, if there is a planet in a relatively close orbit, can there be a habitable planet like an ordinary galaxy?" ”

Although he and Lin Xi left the bridge, they did not really copy the mission briefing ten times, but memorized the briefing word for word, and each wrote a profound review.

As expected, Commander Ye's board was raised high and gently lowered, sparing the two of them this time-after a few months of getting along, Ye Fei's temper had already been figured out by them.

"It's a good idea, it's not impossible, but even if there is such a planet, it is tidally locked on one side towards the white dwarf." Hong Liang said with a smile, "And the gravitational pull of the white dwarf is too great, if the distance is too close, the planet will be torn apart by gravity, so the possibility is not high." ”

"I think this theory seems to have been mentioned." Ye Fei showed a look of reminiscence, "I remember that the information said. The habitable zone of the white dwarf seems to be more than 3 million kilometers. ”

"Three million kilometers? So close? Yi Qi's beautiful eyes widened, and the others couldn't help but be stunned.

The distance of more than three million kilometers is far beyond the human senses, but on a cosmic scale, it is as close as face-to-face!

The average distance between Mercury and the Sun is still 58 million kilometers!

Ji Xiaotong and the others were also very surprised, he didn't know how far Mercury and the sun were, but more than 3 million kilometers was only a dozen lightseconds of light distance.

Fire control officers like Ji Xiaotong and Lin Xi didn't have much impression of the abstract concept of distance, but a dozen lightseconds happened to be the edge of the effective combat range of the battleship, and the sensitivity of their profession immediately made the two of them have a concrete concept of this distance.

Hong Liang shook his head and said, "It's not very likely, the red giant stage before the supernova explosion." It must have swallowed up all the nearby planets. The chances of such a planet are slim, unless the gravitational pull of a white dwarf happens to catch a wandering planet. ”

"The odds are too low, aren't they?" Ji Xiaotong said with a sigh.

"I don't think it's useful to capture it, it's not a dozen or two billion years. How can life evolve on planets? Can a white dwarf shine that long? Hong Liang continued to speculate.

Yi Qi wanted to speak and stopped. A strange face; Yue Ting's gaze wandered. Hold back a smile.

The military ranks of the two of them were too low, and they were embarrassed to say the answer, but Ye Fei had no scruples. He patted Hong Liang's shoulder seriously: "Lao Hong, you really said this badly, the main sequence star stage of the sun is about 9 billion years, and the white dwarf star has a long time to shine." ”

"Huh? So long? Hong Liang's chin almost hit his foot, "Impossible, right?" ”

"Theoretically, it would take billions of years for a white dwarf to dissipate its residual heat and become a black dwarf that doesn't emit light, and I don't know if it's right or not." Ye Fei said.

Although no black dwarf has been discovered so far, the astronomical community firmly believes that black dwarfs exist.

According to the traditional theory, it takes longer for a star to evolve into a black dwarf than the age of the universe, but the new theory believes that the black dwarf has not been discovered so far, and in addition to the fact that the black dwarf itself is neither emitting nor heating and difficult to find, the lack of age of the star region where the Milky Way is located is the most important reason!

After mankind entered the cosmic age, astronomical theories have exploded, for example, today's literary circles have long overturned the bizarre Big Bang theory, replaced by the regional explosion theory, that is, galaxies similar to the Milky Way will gradually shrink at the end of evolution, forming larger black holes or a specific celestial body that humans cannot infer yet.

When the mass of this object reaches a certain level, a massive explosion occurs, resulting in the emergence of new nebulae that gradually converge into new galaxies over a timeline of hundreds of millions of years.

In other words, the age of the universe is much longer than human inference, but the age of the generalized star field in which the Milky Way is located is only more than 10 billion years old.

The new theory solves the paradox between the cosmic scale of more than 400 years and the time scale of more than 10 billion years, but the astronomical community firmly believes that this theory, like the abandoned Big Bang theory, is just a transition in the process of human search for truth.

Yi Qi suddenly said: "I remember that there is a crystalline white dwarf in the constellation Centauri......"

"Yes, yes, I've heard of it too!" Yue Ting also hurriedly said.

Ye Fei couldn't help laughing: "That thing says it's a diamond, but it's actually not quite the same as a diamond!" Besides, it didn't become a black dwarf. "Women, women, there's nothing you don't get excited about when it comes to jewelry.

The white dwarf star mentioned by Yi Qi has a huge diamond with a diameter of more than 3,000 kilometers inside!

Originally, he really didn't know that there was a white dwarf star known as the "mother of diamonds" fifty light years away from the earth, or that after serving as the commander of the solar system group army, he knew that there was this love-hate celestial body when he learned about the surrounding galaxies.

The main component of a white dwarf is carbon, and due to high temperatures and pressures, the carbon inside it forms huge crystals over a long period of time, a process known as crystallization. However, most astronomical space believes that the carbon crystals in white dwarfs have a similar structure to diamonds, but there is a difference in the essence of zài, and no one knows the crystallized structure of white dwarf materials.

Several female officers were a little embarrassed, and at this time Xia Zhuoyan reported: "Boss, the basic detection is over." ”

Everyone's attention was immediately drawn back from the boundless fantasies.

"How's it going?" Ye Fei strode back to the command chair and sat down.

"White Dwarf 001 only has a disk of dust, not a planet we need." Xia Zhuoyan said succinctly.

Of course, the number of detected jù is more than this, but the other number jù is basically celestial data such as the mass and volume of the white dwarf star itself, and this thing is only liked by those who engage in astronomy, and it is impossible to say that there is no difference at all.
