In the outermost Oort nebula belt of the Centauri Galaxy, a spaceship is flying rapidly towards the Centauri Galaxy, and all kinds of detection instruments on the spaceship are full of vitality, especially electromagnetic wave signal receivers, like a pair of huge ears, are silently receiving electromagnetic signals from the solar system and the Centauri Galaxy.

"Didi~Didi~"

The unmanned spacecraft is controlled by intelligent programs, of course, because it uses quantum communication technology, and it can be remotely controlled by the control center on this side of the solar system.

But from the beginning of the design of this spacecraft, more artificial intelligence program control systems were used, so at this time the spacecraft was still under the control of intelligent programs.

"There is no signal from the past that we sent a few years ago."

In the outer space of Mars, in the space city where the Xinghan Academy of Astronomical Sciences is located, scientists are very busy, and through quantum communication, they can maintain real-time communication with spacecraft 4.3 light-years away.

A few years ago, scientists conducted a series of scientific tests and built a super-large electromagnetic wave signal generator, which was oriented to the Centauri galaxy to generate electromagnetic wave signals regularly, in order to see if the spacecraft could receive electromagnetic wave signals from this side of the solar system today.

"It seems that there is a reason why we can't receive information from the universe, the Centauri galaxy and the solar system are so close, and we have built a large electromagnetic wave transmitter and carried out directional transmission, but it is still not received on this side of the Centauri galaxy."

Liu Peiqiang touched his chin and pondered.

"Could it be because we just missed the time?"

Wang Songling thought for a while and asked.

"No, four years ago, we continued to send waves of electromagnetic signals for several months, and in the future, we will send signals again regularly every once in a while, which is absolutely impossible to miss."

"And these are all rigorously calculated, and there will never be such low-level mistakes."

Long Zhankong was complicated by this, he shook his head and said.

"The propagation of electromagnetic waves will be affected by many factors, this cosmic void is theoretically vacuum, but this is not the case, the last time Longyuankong did not say that this space and time are the main elements of the universe, maybe we think it is a vacuum void, it is full of space, this space may have a huge weakening of electromagnetic waves."

"It may not be obvious in a relatively short range, but as soon as the distance is long, the electromagnetic wave is weakened very much, and it may even be completely absorbed by space."

Liu Peiqiang's mind remembered the words of the last time Long Yuankong was directed, and he also boldly speculated.

"Your inference is not entirely unreasonable."

Qin Yi looked at Liu Peiqiang and said with a smile.

On the other side, far away on the Centauri Galaxy, the spaceship is advancing in the void, and various detection instruments are also beginning to collect information in the Centauri Galaxy.

Previously 4.3 light-years away, even the most powerful space telescope could only observe three stars in the constellation Centauri, and knew nothing about its neighbor.

But now that the spacecraft has arrived in the Centauri Galaxy, the situation in the Centauri Galaxy will soon be known with the exploration of various advanced scientific instruments.

"Didi~Didi~"

The spaceship's probe instruments were collecting all sorts of data, and then they began to calculate everything in the Centauri Galaxy.

"A star in the constellation Centauri, with a mass of 1.1 times that of the Sun and a diameter of 1.2 times that of the Sun~"

"B Centauri, 0.9 times the mass and 0.86 times the diameter of the Sun."

"C Centauri, also known as Proxima Centauri, has a mass of 0.12 times that of the Sun and a diameter of one-seventh of the diameter of the Sun~"

The first information that came out was the data of the three stars in the Centaur Galaxy, the mass and volume, and scientists generally like to use the sun as a reference when calculating the mass and volume of stars.

In this way, you can know what type of star the star belongs to, whether it is a dwarf, a giant star or a supergiant, a black dwarf, a dwarf, a red dwarf, a yellow dwarf or a white dwarf, or a red giant, a blue giant, a red supergiant, and so on.

Different types of stars have different characteristics, according to the stage of evolution of stars: protostars, main-sequence stars, red giants or red supergiants.

Among them, the protostars are the newly formed stars, the main sequence stars are the young to middle age of the stars, and the red giants and red supergiants are the old stars.

According to the density of stars: black holes, neutron stars, white dwarfs, main-sequence stars, red giants or red supergiants, the density of stars decreases in turn.

Take the Sun as an example, the Sun is a main-sequence star, a single star, a G-type star, and a yellow dwarf. In about 45-5 billion years, the Sun will cease to be a main-sequence star and will become a red giant, then a white dwarf, and eventually a black dwarf.

Stars are the masters of a planetary system, and everything in the entire planetary system is governed by stars.

Star A and star B in the Centauri galaxy are not much different from the Sun in terms of mass and volume, and they all belong to red dwarfs, while Centauri C star is too small in mass and small in size, although it also belongs to the series of red dwarfs, but it shows that it is much lower than the Sun.

However, the closest to the Sun is this Centauri C star, which is only 4.2 light-years away, but the Centauri galaxy is a triad system, and the three stars rotate each other, so now Centauri C is closer to the solar system, and in many years it may be Centauri A or B.

"Centauri A has 7 planets around, Centauri B has 5 planets, and Centauri C has only one planet."

Soon, the detection instrument also detected the number and position of the planets in the Centauri Galaxy, orbits, periods, mass, rotation, types, and so on.

And began to draw a map of the stars in the Centauri galaxy in the computer, and the three stars converged together as if three behemoths were fighting for territory and things.

Massive stars have a strong gravitational pull and grab more land and planets, while stars with less mass and less gravity will grab fewer places and planets, and poor Centauri C has only one planet.

"Based on the information available so far, we believe that in the Centauri system, the four rocky planets A3, A4, B3, and B4 are very likely to harbor life."

"These four planets are similar to our Earth's situation, they are at a moderate distance from the stars, they are in the habitable zone of life in the planetary system, and they are all rocky planets, and it may be very likely that life planets will be born."

"However, the mass of the two planets A4 and B3 is much smaller than that of the Earth, just about the same as Mars, which may not be conducive to the birth of life."

"The most likely ones are the planets A3 and B4, and as for the planet C Centauri, it is too close to be a living planet."

As soon as the data was transmitted back to Earth, scientists began to analyze the planets in the Centauri system, deducing that those planets might be life-threatening.

"The triad system is too chaotic, the planets revolve around the stars, and the stars are constantly rotating with each other, I think there may be no life in this Centauri galaxy, there can be no living planets."

Some scientists feel that the system of the Centauri galaxy is too chaotic, and that everything in the Centauri galaxy is not stable compared to the single-star planetary system of the solar system.

And the birth of life requires a stable environment, life is too fragile, but it is also full of miracles.

"It's hard to say, but soon the answer will be revealed."

Scientists continue to look forward to the fact that as long as the spacecraft actually enters the interior of the Centauri galaxy and obtains more information, scientists will be able to know whether there are any living planets in the Centauri galaxy, whether there is a civilization, and what level of development this civilization has reached.

The spacecraft continued to fly towards the Centauri system, and began to launch probes throughout the Centauri system to gather more information.

After the probe was launched, the spacecraft began to slow down, and the current speed was accelerated after a long acceleration period, which also required a relatively long process.

While slowing down, the probes on the spacecraft were still not idle, especially the electromagnetic wave signal receiver, which was constantly aimed at the interior of the Centauri galaxy.

"Didi~Didi~"

When the spacecraft flew through the Alto Nebula and officially entered the outer edge of the Centauri Galaxy, the electromagnetic signal receiver on the spacecraft finally responded.
