Chapter 497

From the data sent back by the sentinel robot, on the other side of the wormhole is a desolate planet. At one glance, there is nothing but rocks, mountains and craters.

There are no plants, no animals, no aliens, no alien buildings, no sign of civilization.

It seems that this is a dead planet like the moon.

"There is no air, no atmosphere, the temperature is 175 ℃, the radiation is strong, and the ultraviolet is 17300 times of the intensity of the earth's ultraviolet Not suitable for human survival. "

"Electromagnetic wave signal is detected. The signal strength is very low. It should come from a very remote star region."

"Dark energy was detected at 79% of the solar system's dark energy concentration."

"We found a super star with a brightness about 340000 times that of the sun and a diameter of about 2.375 billion kilometers..."

"Try to locate, retrieve map data Data matching Didi... Data match successful It's about 6000 light-years away from Alpha Centauri, which is uy shield

……

"I'll go. It's shield uy. Our cosmic caravan has been to that star field for a long time. It's not suitable for human survival."

"Yes, it's not suitable for any kind of life, and as a red supergiant, shield uy has a life span of only 10 to 50 million. After that, the star will become a black hole due to the collapse of its core."

"The wormhole dug this time is of little value. It's better to close it and dig another wormhole."

The data sent back by the sentinel robot disappointed everyone, including Zhang Wei, because the cosmic caravan of the earth civilization has been to this star region, and collected a lot of data, carried out detailed analysis, and concluded that this is a very low value star region.

"Withdraw the sentinel droid, close the wormhole and reopen it at another location two days later."

After Zhang Wei gave the order, he left the command center directly. Other scientists naturally did the rest of the work.

The media moved to report on the experiment on a large scale.

"The second time we opened the wormhole, there was a setback. At the other end of the wormhole, there was a shield uy 6000 light-years away from Alpha Centauri, the largest star known to man."

Galaxy weekly: "wormhole will open again in two days. What kind of world will this wormhole bring to us? Welcome to leave a message and discuss in our virtual world column."

Other media are also reporting on this matter. It's not necessary to popularize science on shield uy by the way. Everyone's biological computers store data related to shield uy. You can retrieve these data as long as you have an idea.

Shield uy, a red supergiant in the constellation of shield, is the largest star known to human beings, surpassing vy, the largest star in the past.

What's the concept of this star with a diameter of 2375828000 km? If you place shield uy in the center of the solar system, its diameter will exceed the orbit of Jupiter and approach the orbit of Saturn. As for the earth, ha ha, the earth has been swallowed by mercury, Venus, earth, Mars and Jupiter, including their orbit. According to calculation, this star can hold about 20 billion suns, or about 200 million earth.

Use another calculation method to show the Niubi of shield uy. The speed of light is fast enough. But it takes more than 9 hours for the light to circle the equator of shield uy, and only 14.5 seconds for the light to circle the equator of the sun.

Shield uy is not only large in size, but also very bright. Its brightness is 340000 times that of the sun. It is one of the stars with the highest luminosity. If the earth revolves around shield uy, it is absolutely impossible to produce life, because everything will be scorched.

However, for such a large star, its life span is generally not very long. This is the case for shield uy, which has a life span of only 10 to 50 million years. After these tens of millions of years, the star will become a black hole due to nuclear collapse and supernova, and the gamma ray burst produced by supernova explosion will also harm the planetary system near the star, and may even affect the earth Global civilization poses a fatal threat to earth civilization, because gamma ray is a form of energetic light, its energy is far greater than visible light, and the energy of a single gamma ray photon is more than a million combinations of visible photons, which can destroy human DNA and kill human beings. The mass extinction of Ordovician species on earth 450 million years ago was considered by scientists to be caused by gamma ray bursts At that time, 85% of marine life died out. Of course, with the current level of science and technology of earth civilization, there is no need to worry about this threat.

……

Two days later, the wormhole is about to open again, and the vision of the whole earth civilization is focused on this event related to the future of the earth civilization.

"I hope that the earth civilization will collide with the Universiade. The other end of the wormhole is a place where the overall strength of the earth civilization can soar!"

People prayed in their hearts one after another, while Zhang Wei quietly gave the order. After the wormhole digger was full of energy, it ran again, and a new wormhole was dug at a place far away from the last astronomical unit.

Then, ten sentinel robots went through the wormhole and came to the other end of the wormhole.

It has to be said that the luck of earth civilization seems to be good. The other end of the wormhole is still a planet, and a living planet.

Just out of the wormhole, the sentinel robot found lush plants. However, these plants are unimaginably large. At a glance, they found giant trees with a diameter of about 0.5km. Even ordinary weeds are higher than human beings.

"Didi, start collecting data."

The sentinel robot moves step by step, takes out all kinds of instruments and equipment from the space equipment, and starts to carry on the omni-directional inspection to this strange world.

"Atmospheric composition: 27.3% oxygen, 31.5% nitrogen Suitable for human survival. "

"Dark energy has been detected at a concentration of 103 times that of the solar system."

"No electromagnetic signal, no quantum signal."

"Bio wave signal, soul wave signal detected..."

"Try to locate, retrieve map data Data matching Didi... Match failed According to the analysis of the known data, 63.5% of the probability is outside the galaxy. "

The information sent back by the sentinel robot made everyone think about it. The world seems a little strange. Not only outside the galaxy, but also the concentration of dark energy is so high

At this time, the sentinel robot sent back a message that made everyone excited: "Didi, quantum radar detected that there are a large number of unidentified organisms flying in the sky, these organisms have no wings, and they are similar to humans in body shape! Again, according to the detection results of quantum radar, there are a large number of unidentified organisms flying in the sky... "
