Chapter 157: Meeting Side by Side 2
Three Earth days later, the Forsaken followed its calculated route to the closest point to the star at its closest point, light-years.
Observations suggest that there are a large number of early stellar features within this galaxy.
Therefore, Xiaole judged that the age of this star would not exceed one billion years, and compared to the sun, she was still only a juvenile star.
Because the Forsaken is only a 100-meter-level spacecraft after all, and it does not carry the top telescope of the original earth's scientific and technological level.
Therefore, neither Hua Kejing nor Xiaole can determine how many planets are located in this "close" star system, and whether there are habitable planets.
For this reason, Hua Kejing complained to Xiaole and said, you are such a capable artificial intelligence that you can't figure out the situation in front of you.
Xiaole replied, can you see ants in the grass a hundred meters away?
Hua Kejing doesn't know if this metaphor is appropriate,
But the planets themselves don't emit light, and it's not easy to find them in the dark picture of the universe.
Just like in the age of the earth, many people may have the following questions.
Why are scientists able to detect galaxies millions of light-years away, but not sure whether Planet Nine exists?
Why can the Hubble telescope see galaxies 13.4 billion light-years away, but not planets 4.2 light-years away?
This may seem illogical, but the reason is simple.
First of all, to find a planet, we have to look directly at it, into a tiny part of the sky.
But to find a galaxy, we can look at her in any direction, no matter where she is.
Because these galaxies are made up of stars, they are luminous and they are bright.
And the planet itself does not emit light, it only reflects the light of the star.
They will be very bright for planets close to the Sun, such as Mercury, Venus, Mars, and several other planets.
But in the outer reaches of the solar system, the universe is extremely dark, so even if we point our telescope at this planet, it is just a tiny black spot.
Photography enthusiasts can increase the noticeable brightness of an object with a long exposure.
In astronomical observations, we can also point the telescope at the darkest places in space, expose them for a long time, let the light continue to superimpose in the image, and then discover countless galaxies.
But to find a planet, other methods need to be introduced, usually to infer its position based on the gravitational influence of a potential planet on a known object.
This is difficult to detect, especially when the planet is still distant and unknown.
Just like the star system in front of them, Hua Kejing and Xiaole can be said to know nothing except for the stars in their core position.
Then there was no chance to touch another melon along a known planet, and his eyes were absolutely black.
……
After observing for nearly a week, Hua Kejing couldn't help sighing: "It's so close, but I can't catch the melon in front of me." ”
For this, Xiaole comforted him, there are seven or eight billion people on the earth, and you can see many people on the street as soon as you go out.
However, if you come to Egret City at some point and want to see a specific person, the chances are very likely to be zero.
That's probably what it means.
Hearing this, Hua Kejing asked rhetorically: "The probability is very likely to be zero?" Then we don't have a chance at all? ”
"Not necessarily."
"It means chance."
Hua Kejing shook his head, he believed that there was a high probability of planets in this star system.
But just because it exists doesn't mean you can observe.
It's like a button that falls off your coat while driving,
It got under the seat,
And then tragedy came,
Even if we can be sure it's in the car,
But there's a good chance you won't be able to find it.
That's how it should be.
But Hua Kejing still has to continue to work.
Such as astrometry, direct imaging, radial velocity, transit, gravity lensing.
There are things that make him energetic!
The overhaul of the Forsaken spacecraft was complete anyway, and he had no other tasks to complete before entering the hibernation pod.
So let's look for basic recovery training while doing it.
Of course, with Xiaole and the spacecraft's intelligent monitoring system, Hua Kejing actually doesn't have much work to do.
It can be summed up in one word - etc., etc.
Finally, after continuously observing nearly 21 Earth days, Xiaole came with good news.
Luck broke out and found it.
It was a huge gaseous planet with orbit and a volumetric mass about the same as Saturn in the solar system.
Later, Xiaole discovered another rocky planet fifteen days later.
"The mass ratio is about 142.1% of the Earth, but the volume is about the same as that of the Earth, which means that it has a higher overall density."
While listening to Xiaole's introduction, Hua Kejing asked, "Is it a habitable planet?" ”
"It's not." Xiaole replied without hesitation, "At least it is not suitable for human habitation." ”
"Not in the habitable zone?"
"Yes, it's too far away from the star, and even if the planet has enough atmosphere, the surface temperature will remain at least minus 180 degrees Celsius because of the lack of sufficient light and thermal radiation."
"It's really not suitable for human habitation, so is it possible to have an environment similar to Titan."
PS: Titan, also known as Titan, is a moon orbiting Saturn, the largest of Saturn's moons, and the second largest in the solar system.
"Of course it's possible."
"So it's possible that the liquid methane or ethane oceans could also give birth to other forms of life?"
"Possibly."
"So this star system could also be born and have an intelligent civilization?"
"Possibly."
"So why don't we run?"
"Run for what?"
"What if the Forsaken is discovered? What if we get caught? ”
"It's unlikely?"
"Do you know what the conditions are for stepping on ants in a sports field?"
"There are enough ants."
"Yes."
"Oh." Hua Kejing thought thoughtfully, "But you compare us to ants, is that okay?" ”
"In this universe, there is not much difference between you and ants."
"Huh."
Hua Kejing doesn't mind the harshness of artificial intelligence's speech.
In fact, one person and one machine often talk about things that are not there.
It's not that Xiaole's style has changed, it's that she's worried about her mental condition and mental health.
"However, 0.131 light-years is still too close." Hua Kejing suddenly remembered something, and then assumed, "If there is a super cosmic civilization here with outstanding strength, then it is very likely that they will find me?" ”
But Xiaole put forward a negative view: "The super cosmic civilization you envisioned is very likely to be impossible to exist?" ”
"Why?"
"Because this is the Milky Way."
"Oh, like Earth, like the solar system."
Hua Kejing nodded, and then fell silent.
"Yes, like the Earth, like the solar system."
Xiaole also repeated, and then didn't say a word.
……
The Forsaken spaceship continues to fly forward in the vastness of space.
Outside the spaceship,
The star system is moving away,
But the surroundings are still a dark cosmic deep space,
Hua Kejing and Xiaole failed to discover other potential planets,
Of course, there is no imaginary super-cosmic civilization on the long journey to the stars.
It's time to go into hibernation again,
As is customary, Hua Kejing first inspected the spacecraft and then went to the sleeping chamber.
Airplanes...... Airplanes...... Airplanes......
Press the palm of your hand on the unlocking area and the hatch cover slowly opens.
After some set-up, Hua Kejing lay down inside the sleeping pod.
"See you in 10,000 years."
"Have a good dream."
So, Hua Kejing closed his eyes in the misty sleep aid.
As a result, the lighting, temperature control, air convection and other systems of the Forsaken spacecraft were turned off again, and it became gray and cold, like a lonely meteorite

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