Half a month later,

Hua Kejing miraculously restored physical function and health indicators to the basic level.

Why is it a miracle?

That's because according to the previous rules, every time you go through a dormant cycle, the body function of Huake Mirror will be correspondingly impaired, and the required recovery adjustment period will be correspondingly extended by a few days.

But this time, the adjustment period turned out to be shortened!

.

.

.

So, Xiaole asked Hua Kejing how he did it.

Hua Kejing told Xiaole that anything is possible, and in this cold universe, the existence of life itself is TM a miracle.

But the above reasons are absolutely.

The real reason is that the comet that is about to pass by the Forsaken strongly arouses the interest of Hua Kejing.

Boss Hua never imagined that one day, he would be picked up by a comet.

In order to avoid dropping the chain at a critical moment,

In order to avoid lying in bed and sighing and missing opportunities,

Like a fighter in human history, Hua Kejing stood up the day before the spacecraft was about to reach the closest point to the comet!

Yes, he stood up, and he was in good condition for an out-of-cabin operation.

Of course, it would be inaccurate to call this "dirty snowball" of frozen water and many solid dust particles a comet.

She is essentially an interstellar wandering object.

In the Chinese language, "comet" means broom, and the English name of comet is derived from Greek, with the meaning of tail or hair, long hair.

Therefore, comets are named in the same way both in China and abroad.

The so-called "comet" is a celestial body that enters the solar system and moves around the sun in a light and shape that changes with the solar distance, and has a unique appearance in the form of clouds.

Because the comet nucleus is made of icy material, as the comet approaches the star, the comet material sublimates, forming a hazy comet and a thin stream of material around the ice nucleus.

In addition, because the comet has a small mass and density, when it is far from the sun, it is just a "dirty snowball" of frozen ice with water, ammonia, methane, etc., and many solid dust particles.

It's like this wandering little celestial body that is about to have a relationship with the Forsaken spaceship.

Although it is a giant block of ice with a diameter of 1.45 kilometers, because it is far away from the stars, it does not receive enough radiation, and it does not withstand the pressure of stellar winds, so there is no hazy coma, let alone a tail that is tens of millions of kilometers long, or even hundreds of millions of kilometers.

In the past few days, Xiaole has roughly deduced the main composition of the comet, 95% ice plus 5% impurities.

Ninety-five percent of ice is more than a billion tons of water.

As for the remaining 5% of impurities, it is not clear what they are until they are analyzed in depth at close range.

But what made Hua Kejing reverie the most was a wandering small celestial body flying at 10% of the speed of light, what did she experience?

……

Within the solar system, the Earth revolves around the Sun at a speed of 29.783 kilometers per second.

And there have been many mysterious interstellar visitors who have crossed paths with the solar system, such as the small celestial body named Omomo, which traveled through the solar system at a speed of 44 kilometers per second.

Of all the recorded data, the fastest object observed in the solar system is a comet measuring 66 kilometers per second.

The comet was discovered on December 18, 2018 by astronomer Iwamoto Komatsu and named Comet C2018Y1.

At 6:57 a.m. on February 13, 2019, the comet C2018Y1 met the Earth at close range, and the closest distance between the two was 45 million kilometers, which is slightly closer than the orbit of Mars and the orbit of the Earth.

But in any case, a comet of 66 kilometers per second is incomparable to the comet in front of me, which is more than 30,000 kilometers per second.

When Hua Kejing was still lying down and resting, he asked Xiaole, why did a small celestial body with such a fast speed appear?

Xiao Le told him that under normal circumstances, the movement of celestial bodies in the universe generally moves around the central celestial body, which is mainly affected by the gravitational pull of the central celestial body, in addition to the influence of the reception force brought by the shape of other celestial bodies and the main celestial body.

Therefore, from the transformation relationship between gravitational force and centripetal force, we can see that the speed of the small celestial body is related to the mass of the central celestial body and the distance of the small celestial body from the central celestial body.

In fact, under the gravitational influence of the galactic super-black hole, the movement speed of large-scale objects is actually very fast.

Of course, a comet of 30,000 kilometers per second is quite unusual.

"So, what you just said has something to do with the comet we're encountering now?"

After listening to Xiaole's words, Hua Kejing expressed dissatisfaction.

Because the big ice cube in front of her was just a wandering little celestial body, not to mention a super black hole, and she didn't even have a decent star within a few light years.

Xiao Le was silent for a moment, but he just told him that in the world of super civilization [Miao], small celestial bodies flying at high speed abounded.

"So, why did such a comet appear more than 10,000 light-years away from the heart of the galaxy?"

Hua Kejing continued to ask, but Xiaole couldn't answer the question.

After all, the universe is so vast that every celestial body, or every particle, has its own story.

If a small celestial body was born in the early days of the Big Bang, no one knows what happened to her or how far she traveled over the long years of nearly 14 billion years.

It may be that the long interstellar journey is too boring, or it may be that the pressure in Hua Kejing's heart is too much, or it may be the infinite curiosity about the unknown universe.

All in all, the sudden appearance of the homeless child really made him think about it.

"How on earth did this little celestial body achieve such speed?"

"Is it man-made or natural?"

"Roughly the same direction, the relative velocity is only 25.4 meters and seconds, why is it just like that?"

"Is the target of the small celestial body also the galactic region?"

……

"Don't be cranky, the greater the hope, the greater the disappointment."

Xiao Le's voice suddenly sounded, and in her opinion, strong emotional fluctuations were not conducive to this already incomparably vicissitudes of interstellar travel.

"But don't you think it's too much of a coincidence? Such an empty universe, a celestial body moving so fast, suddenly appeared in front of us. ”

That only shows that there are far more small objects moving at high speed than we think. Moreover, it is not sudden, this is the only case in 130,000 years. ”

"You also said that this is a once-in-130,000-year opportunity, and I decided to go and have a look at that comet."

Hua Kejing has a strong obsession in his heart.

He had never landed on a celestial body outside of the solar system, let alone such an object within reach.

This is definitely another first!

Xiaole did not veto Hua Kejing's plan, but only put forward the premise, if you are physically fit, if the risk factor is not high.

Of course, there is another important factor in this, which is the extraction of water resources.

Because the relative velocity between the comet and the Forsaken is not large, if the next piece of ice can be extracted from more than a billion tons of ice and transported back to the spacecraft, the water pressure of Huake Mirror will be greatly improved for hundreds of thousands of years.

Hua Kejing naturally patted his chest with a smile, saying that there was no problem with his body, and then discussed a detailed plan of action with Xiaole.

I salute every friend who has been with me all the way, thank you for your support!
