Earth Era

readx();>, !

In a room in a residential building in the center of Huasheng City, Zhao Lan, who was sleeping, was awakened by a rapid phone ringing. ︽, Zhao Lan opened her sleepy eyes, took out the phone from under her pillow, pressed the button, and a video call message that had been recorded a long time ago appeared in front of her eyes.

Because the distance between Mars and the earth is too far - the closest distance between the two planets is more than 50 million kilometers, it takes more than three minutes for electromagnetic waves to complete a one-way journey - which means that the distance between the two places is more than 50 million kilometers. The minimum communication delay is more than six minutes, so it is impossible to communicate in real time between the two places, so if people have communication needs, they usually record the information and send it. Now the information Zhao Lan received is such a video message that was recorded in advance and then sent.

Zhao Lan glanced at the contact information and found that it was the information sent by the Xinghai Sky Survey and Observation Base. The specific sender was his colleague in the Xinghai Sky Survey and Observation Base, Zhang Ya.

"Zhao Lan, there is an emergency, you must end your vacation early and come back to work."

In the video message, Zhang Ya's always delicate face is a little dark here, and her hair is a little messy-obviously, this is because the matter is too urgent, so Zhang Ya sent this message before she had time to put on makeup. .

As a friend, Zhao Lan knows what it means for Zhang Ya to go out without makeup. It must have been an extremely urgent matter for this to happen. So the drowsiness that lingered in Zhao Lan's mind finally disappeared at this moment. Zhao Lan sat up on the bed, gathered his energy and continued to watch this video.

"Zhao Lan, did you know? Haishan Er finally erupted. Just half an hour ago! We received a very strong burst of gamma rays and x-rays from Haishan Er. This is different from the fake one in 1843. Explosion. Now we are extremely sure that Haishan Er really broke out this time!"

"What?" Looking at Zhang Ya's excited face and listening to her hoarse voice, Zhao Lan covered her mouth in shock.

Haishan Er is a very famous star. Observing the evolution of this star plays an extremely important role in the well-structured supernova explosion mechanism and stellar evolution mechanism, so people have never relaxed its observation. It's just that the predicted Haishan II eruption will probably occur within 10,000 years, and no one has ever thought that Haishan II will erupt now.

It is foreseeable that this will be the most important stroke in the history of astronomical development of human civilization. Human civilization has not experienced supernova explosions in history - the most famous supernova explosion was observed in the Song Dynasty of the national era. That outburst formed the famous Crab Nebula—but it was the first time a supernova had been observed in such good conditions in a civilization that had sophisticated enough observation equipment and was so close to Earth. The supernova explosion of Haishan Er will surely attract the attention of all mankind in an instant and become the most popular topic in human society. Compared with Haishan Er, no matter what entertainment star or famous person like a sports superstar has to give way.

The most important point is that Zhang Ya's words confirmed the authenticity of this outbreak. This is a real explosion, not the false supernova explosions that have happened in the past.

There are also real and fake supernova explosions. In 1843, Haishan Er had a false outbreak once. In that eruption, Haishan Er even surpassed Sirius in brightness and could be seen during the day. But that outburst was eventually confirmed to be fake. After observation and research, people finally believed that it was because the internal activities of Haishan II were too intense. It caused its luminosity to exceed the Eddington luminosity limit, and the internal radiation pressure exceeded its own gravitational force, so matter equivalent to about one-fifth of the mass of the sun was ejected by it, and finally caused its luminosity Exceptionally raised.

And this outbreak is anything but. This is a real explosion, a gigantic star will instantly turn into fly ash, an infinite amount of stellar matter will be ejected into interstellar space, and a black hole representing its corpse will form inside it...

The explosion of Haishan Er will make heavenly families and physicists all over the world go crazy. As a member of the Tian family, Zhao Lan is no exception.

In the video, Zhang Yan's excited voice was still coming out, but Zhao Lan couldn't care to listen. Zhao Lan got up from the bed at the fastest speed, put on his clothes, washed his face casually, pulled up the suitcase and left here.

Through the huge and transparent fully enclosed glass shield of Watson City, Zhao Lan saw the bright star in the sky with his own eyes. In Zhao Lan's eyes, the star seemed to possess some kind of peculiar magic power, which made Zhao Lan just want to look at it tightly, and didn't want to look away for a moment.

But Zhao Lan knew that nothing could be seen with the naked eye. It is most appropriate to rush to the Xinghai Sky Survey Observation Base as quickly as possible, and use the instruments there to observe and then analyze the data. As a Heavenly Family, Zhao Lan must fulfill his responsibilities in this heroic incident.

Zhao Lan stopped a car and hurried to the Aerospace Interaction Base. There is a space elevator connecting the ground and the space port in the air-space interaction base. Through the space elevator, people can quickly leave the ground and enter space, and then take a ship to the earth in the space port.

In the early days of the beginning of the interstellar age, people had explored the design of the near-Earth and space spacecraft, but this plan was eventually abandoned by scientists and engineers. It's not that the technology of human civilization is not up to the standard, but that the construction cost of the dual-use spacecraft is too high - it must have an extremely tough armor system to resist the high heat caused by the friction of the atmosphere, and it must also be required during take-off and landing. There is a very sophisticated ship control system involved. This would cause its construction cost to more than triple. Not only that, but it also has to carry fuel for acceleration and deceleration when breaking out of the planet's gravity and re-entry into the atmosphere, which makes it necessary to be designed to be very large, which in turn increases the design of the outer armor and the overall structure by a few more. difficulty. For a variety of reasons, people have to give up this design.

In place of the near-Earth and space dual-use ships are the Space Interaction Base, Spaceport, and Space Single-use ship design patterns. In this mode of transportation, the air-space interactive base connects the ground and the spaceport, and the spaceport is connected to the starship. The interstellar spacecraft does not have to enter the atmosphere directly, it will directly enter the port to berth, and the cargo or personnel loaded on it will enter the ground from space through the space elevator in the air-space interaction base.

This design has proven to be efficient and reliable. It is precisely because there are two giant space ports that exist over the Mars Watson City and the Earth's capital city, the space channel connecting Mars and the Earth can be opened, and the Watson City can prosper.

Zhao Lan's Sylvia spacecraft was parked in the spaceport. It was a private small spaceship with advanced equipment and gorgeous shape. Its fastest speed can reach 120 kilometers per second, and the energy and survival materials loaded on it can provide a person with a comfortable life for at least ten years. In the category of civilian spacecraft, the Sylvia spacecraft can already be regarded as the most top-level private vehicle.

Originally, as Zhao Lan, it was absolutely impossible to afford such an expensive spaceship, even if Zhao Lan was a member of the highest-paid group of scientists in human civilization. However, Zhao Lan is the only surviving direct descendant of Zhao Huasheng. She inherited the honor and material rewards granted to Zhao Huasheng by the government of human civilization, and only then got this expensive small spaceship.

Now Zhao Lan is on his way to the Air and Space Interaction Base. Although the driver had already driven the car very fast, and in the low-gravity environment of Mars, the car was about to fly, but Zhao Lan still felt that it was too slow. Under the current circumstances, every second of time delay is a crime in Zhao Lan's interest and career.

Supernova explosions release the most information in the early stages, and as the explosion slows down, less valuable information is observable. Zhao Lan has already missed the initial stage of the most heroic outbreak, and can no longer miss the subsequent outbreak. UU reading www. uukanshu. Otherwise, after returning to the Xinghai Sky Survey and Observation Base, Zhao Lan would probably only be in a daze facing the debris of the explosion.

After anxiously waiting, Zhao Lan finally came to the air-sky interaction base. After verifying his identity, Zhao Lan took the nearest elevator to leave Watson City and embarked on a journey to the space port.

The total length of the space elevator is 48,503 kilometers. It is made of a newly developed ultra-high-strength material, which is extremely strong and low in weight. It is connected to the ground at one end and the spaceport at the other end. The spaceport has the same rotation rate as Mars, which means that the spaceport's speed in space has exceeded the orbital speed of Mars, so it will always be suspended in space and will never fall.

The space elevator started to accelerate slowly, which made Zhao Lan feel a little more dizzy. Zhao Lan stood up, left the seat and walked to the viewing window, looking down to the ground through the huge glass window.

In Zhao Lan's eyes, Huasheng City began to shrink rapidly, and eventually merged with the vast land of Mars, and could no longer be distinguished. And waiting for Zhao Lan in front of him is a three-hour trip to space. (To be continued..)
