Chapter 497: Shield UY

Judging from the data sent back by the sentinel robot, on the other side of the wormhole, there is a desolate planet. At a glance, there is nothing but rocks, mountains and craters.
No plants, no animals, no aliens, no alien architecture, no signs of civilization.
It seems that this is a dead planet like the moon.
"There is no air, no atmosphere, the temperature is 175 degrees Celsius, the radiation is strong, and the ultraviolet light is 17300 times the intensity of the earth's ultraviolet light ... not suitable for human survival."
"The electromagnetic wave signal is detected, the signal strength is very low, it should be from a very distant star field."
"Dark energy is detected at a concentration of 79% of the solar system's dark energy concentration."
"I found a super star with a brightness of about 340,000 times that of the sun and a diameter of about 2.375 billion kilometers ..."
"Try to locate and retrieve the star map data ... in the data matching ... didi ... the data matching is successful ... about 6,000 light-years from the Alpha Centauri, the star is UY Shield."
...
"I went, it turned out to be UY Shield. Our cosmic caravan has already been to that star field, which is simply not suitable for human survival."
"Yeah, it's simply not suitable for any life to multiply, and as a red supergiant, UY Shield has a life span of just 10 million to 50 million. After that, this star will change due to nuclear collapse and supernova change. Into a black hole. "
"The wormhole dug this time is of no value, it is better to close it and re-cut a wormhole."
The data sent back by the sentinel robot made everyone including Zhang Wei feel a little disappointed, because the cosmic caravan of the earth civilization has visited this star field, and collected a lot of data, conducted a detailed analysis, and reached a conclusion , Here is a star field with very low value.
"Withdraw the sentinel robot and close the wormhole. Two days later, reopen the wormhole at another location."
After Zhang Wei gave the order, he left the command center directly. Naturally, other scientists would do the rest.
The media took action and reported on this experiment on a large scale.
"Empire Times": "The second time the wormhole was opened, it encountered setbacks. The other end of the wormhole turned out to be UY Shield, 6000 light-years away from the alpha star Centauri, the largest star known to man so far."
"Galaxy Weekly": "Wormhole will open again in two days. What kind of world will this wormhole take us to? Welcome everyone to leave a message and discuss in the virtual world column of this newspaper."
Other media are also reporting on this incident, and incidentally popularizing science on UYS of the Shield. In fact, this is not necessary at all. Everyone ’s biological computer stores relevant information on the UY of the Shield. You can adjust these materials as long as you move your mind. take out.
UY Shield is a red supergiant star in Shield. It is also the largest star known to man so far. It surpasses the VY of Canis Major that was considered the largest star in the past.
This star has a diameter of 237,5828,000 kilometers. What is this concept? If UY Shield is placed in the center of the solar system, its diameter will exceed Jupiter's orbit (5.20 astronomical units, 778547200 kilometers) and be close to Saturn's orbit (9.58 astronomical units, 1433449370 kilometers). As for the Earth, huh, the Earth has been engulfed by Mercury, Venus, Earth, Mars and Jupiter, including their orbits. According to calculations, this star can hold about 20 billion suns, or about 200 billion earths.
Let's use another calculation method to show the power of UY Shield. The speed of light is enough. However, it takes more than 9 hours a week for the light to circle the equator of UY Shield, and the time for the light to circle the sun equator is only 14.5 second.
UY Shield is not only large in volume, but also very bright. It is 340,000 times brighter than the sun and is one of the most luminous stars. If the earth revolves around UY Shield, it is absolutely impossible to produce life, because everything will be burnt. Too.
However, the life of such a large star is generally not very long, as is the case with UY Shield. The life span of UY Shield is only 10 million to 50 million years. After these tens of millions of years, this star will be The nuclear collapsed supernova turned into a black hole, and the gamma-ray burst produced by the supernova explosion would also harm the planetary system near this star, and may even affect the earth's civilization, causing a fatal threat to the earth's civilization, because gamma rays are energy Abundant form of light, whose energy is much greater than that of visible light, and the combination of a single gamma-ray photon energy greater than 1 million visible photons can destroy human DNA, thereby killing humans. Ordovician species on Earth are 450 million years ago. The extinction was considered by scientists to be caused by gamma-ray bursts, which led to the extinction of 85% of marine life. Of course, at the current technological level of earth civilization, there is no need to worry too much about this threat.
...
Two days soon passed, the wormhole was about to open again, and the focus of the entire earth's civilization was again focused on this important event related to the future of the earth's civilization.
"I hope that the civilization of the earth will hit the luck, and the other end of the wormhole is a place where the overall strength of the civilization of the earth can soar!"
People prayed inwardly, and Zhang Wei calmly gave orders. After the wormhole excavator was full of energy, it started to run again ~ EbookFREE.me ~ A astronomical unit far away from the place where the last wormhole was excavated A new wormhole was cut in place.
Then, ten sentinel robots crossed the wormhole and came to the other end of the wormhole.
It must be said that the luck of the earth civilization seems to be good, the other end of the wormhole is still a planet, and it is a living planet.
As soon as he walked out of the wormhole, the sentinel robot found lush plants. However, these plants were unimaginably large. At first glance, they found giant trees with a diameter of about 0.5 kilometers. Even ordinary weeds are more human To be high.
"Beep, start collecting data."
Sentinel robots acted step by step, took out all kinds of instruments and equipment from the space equipment, and began to carry out a comprehensive inspection of this strange world.
"Atmospheric composition: oxygen content 27.3%, nitrogen content 31.5% ... suitable for human survival."
"Dark energy is detected and the concentration is 103 times that of the solar system."
"No electromagnetic wave signal is detected, no quantum signal is detected."
"Bioelectric wave signal, soul wave signal detected ..."
"Trying to locate and retrieve star map data ... during data matching ... didi ... matching failure ... According to the analysis of known data, there is a 63.5% possibility that it is outside the galaxy."
The information sent back by the sentinel robot reminded everyone. This world seems a bit strange, not only outside the galaxy, but also the concentration of dark energy ...
At this moment, the sentinel robot sent back a message that excited everyone: "Beep, the quantum radar detected that there are a large number of unknown organisms flying in the sky. These organisms have no wings and are very similar in size to humans. Similar! Repeat, according to the detection results of quantum radar, there are a lot of unknown organisms flying in the sky ... "
