In the Oort Nebula belt at the outermost edge of the Centaur Galaxy, a spacecraft is flying rapidly towards the Centaur Galaxy. The various detection instruments on the spacecraft are fully activated, especially the electromagnetic wave signal receiver, which is like a pair of giant
The ears are silently receiving electromagnetic signals from the solar system and the Centauri galaxy.
"Didi~Didi~"
The unmanned spacecraft is entirely controlled by intelligent programs. Of course, because it uses quantum communication technology, it can also be completely controlled by the control center in the solar system.
However, from the beginning of the design, this spacecraft mostly adopted an artificial intelligence program control system, so at this time the spacecraft is still under the control of the intelligent program.
"The signal we sent years ago is not being picked up."
In the outer space of Mars, in the space city where the Xinghan Institute of Astronomy and Astronomy is located, scientists are very busy. Through quantum communication, they can maintain real-time communication with the spacecraft 4.3 light-years away.
A few years ago, scientists conducted a series of scientific tests and built a very large electromagnetic wave signal generator, which regularly generated electromagnetic wave signals directed towards the Centauri galaxy. Just for today, take a look.
Can this spacecraft receive electromagnetic wave signals from this side of the solar system?
"It seems that there is a reason why we cannot receive information from the universe. The Centaur Galaxy is so close to the solar system. We have built large electromagnetic wave transmitters and conducted directional transmissions. But here in the Centaur Galaxy
Still can’t receive it.”
Liu Peiqiang touched his chin and said thoughtfully.
"Is it because we just missed the time?"
Wang Songling thought for a while and asked.
"No, 4 years ago, we continued to transmit waves of electromagnetic waves for several months, and in the future, we will continue to transmit electromagnetic waves regularly every once in a while.
Once a signal is emitted, it is absolutely impossible to miss it.”
"And these have been strictly calculated, and such low-level errors will never occur."
This matter is complicated for Long Zhankong, he shook his head and said.
"The propagation of electromagnetic waves will be affected by many factors. The void of the universe is theoretically a vacuum, but this is not the case. Last time, Long Yuankong said that space and time are the main elements that make up the universe. Maybe we think it is a vacuum.
The void fills the space, and this space may greatly weaken electromagnetic waves."
"It may not be obvious within a relatively short distance, but when the distance is long, the electromagnetic waves are greatly weakened, and may even be completely absorbed by space."
Liu Peiqiang recalled what Long Yuankong said last time in his mind, and he boldly speculated.
"Your inference is not completely unreasonable."
Qin Yi looked at Liu Peiqiang and said with a smile.
On the other side, far away in the Centaur Galaxy, the spacecraft is advancing in the void, and various detection instruments are beginning to continuously collect information in the Centaur Galaxy.
Previously, at a distance of 4.3 light-years, even the most powerful space telescope could only observe three stars in the Centauri Galaxy. Other than that, it knew nothing about this neighbor.
But now that the spacecraft has arrived at the Centaur Galaxy, with the exploration of various advanced scientific instruments, the situation in the Centaur Galaxy will naturally be clearly understood soon.
"Didi~Didi~"
The detection instruments on the spacecraft continued to collect various data, and then began to calculate everything about the Centauri galaxy.
"Star Centauri A has a mass of 1.1 times that of the sun and a diameter of 1.2 times that of the sun~"
"Star Centauri b has a mass of 0.9 times that of the sun and a diameter of 0.86 times that of the sun."
"Star C Centauri, also known as Proxima Centauri, has a mass of 0.12 times that of the sun and a diameter that is one-seventh of the diameter of the sun~"
The first information that came out was the data, mass, and volume of the three stars in the Centaur Galaxy. 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 is, whether it is a dwarf, giant or supergiant, whether it is a black dwarf, a dwarf, a red dwarf, a yellow dwarf or a white dwarf, or a red giant, a blue giant or a red supergiant
etc.
Different types of stars have different characteristics and are classified according to their evolutionary stages: protostars, main sequence stars, red giants or red supergiants.
Among them, protostars are newly formed stars, main sequence stars are young to middle-aged stars, and red giants and red supergiants are 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 order.
Take the sun as an example. The sun is a main sequence star, a single star, a g-type star, and a yellow dwarf star. In about 4.5-5 billion years, the sun will no longer be a main sequence star and will become a red giant and then a
A white dwarf star will eventually become a black dwarf star.
Stars are the masters of a planetary system. Everything in the entire planetary system is controlled by the star. If you know and understand the situation of the star, you can roughly analyze the situation inside the galaxy.
Stars A and B in the Centauri Galaxy are not much different from the Sun in terms of mass and volume, and are both red dwarfs. However, Star C in Centauri is too small in mass and volume, although it is also a red dwarf.
series, but it shows that the sun is much, much lower than the sun.
However, the closest star to the sun is Centauri C, which is only 4.2 light-years away. However, the Centauri galaxy is a triple system, and the three stars rotate with each other, so now Centauri C is farther from the solar system.
Very recently, in many years it may be Centauri A or B.
"Centauri a is surrounded by 7 planets, Centauri b is surrounded by 5 planets, and Centauri c is surrounded by only one planet."
Soon, the detection instruments also detected the number and position, orbit, period, mass, rotation, type, etc. of the planets in the Centauri galaxy.
And began to draw a star map in the Centaur Galaxy on the computer. The three stars gathered together like three behemoths fighting for territory.
A star with a large mass has a strong gravitational force and can capture more territory and planets. A star with a small mass has a small mass and has a small gravity, so it can capture less territory and planets. The poor Centauri C only has one planet.
"Based on the information currently obtained, we believe that the four rocky planets a3, a4, b3, and b4 in the Centauri galaxy are very likely to give birth to life."
"These four planets are similar to our Earth. They are at a moderate distance from the star, are within the habitable zone for life within the planetary system, and are all rocky planets. They may be very likely to give birth to life planets."
"However, the masses of the two planets a4 and b3 are much smaller than the mass of the earth. They are only about the same as Mars, which may not be conducive to the birth of life."
"The most likely ones are the two planets a3 and b4. As for the planet Centauri C, it is too close and the possibility of it being a life planet is very small."
As soon as the data was transmitted back to Earth, scientists began busy analyzing these planets in the Centauri galaxy and inferring which planets might be capable of giving birth to life.
"The triad system is too chaotic. The planets revolve around the stars, and the stars are constantly rotating with each other. I feel that life may not have been born in this Centaur galaxy, and there is no possibility of a life planet."
Some scientists also feel that the system of the Centauri Galaxy is too chaotic. Compared with a single-star planetary system such as the solar system, everything in the Centauri Galaxy is not stable enough.
The birth of life extremely requires a stable environment. Life is too fragile, but it is also full of miracles.
"It's hard to say, but the answer will soon be revealed."
Scientists continue to look forward to it. As long as the spacecraft actually enters the Centaur galaxy and obtains more information, scientists can know whether there are any life planets in the Centauri galaxy and whether civilization has been born. This civilization
What level of development has it reached?
The spacecraft continued to fly towards the Centaur Galaxy, and at the same time began to launch detectors everywhere in the Centaur Galaxy to collect more information.
After the probe was launched, the spacecraft also began to slow down slowly. The current speed has accelerated after a long acceleration period. This deceleration also requires a relatively long process.
While slowing down, the detectors on the spacecraft were still not idle, especially the electromagnetic wave signal receiver, which was constantly aimed at the interior of the Centaur galaxy.
"Didi~Didi~"
When the spacecraft flew through the Orto Nebula belt and officially entered the edge of the Centauri galaxy, the electromagnetic wave signal receiver on the spacecraft finally responded.
