() "Hiss ......"

A sharp sound of air flow sounded, and the side of the repair warehouse facing Chen Yu slowly rose, revealing the protective clothing that was surrounded by white mist inside the box.

The air pressure is normal, and the cabin can be entered.

After receiving instructions, Chen Yu got into the cabin and put on the purple protective suit lining.

The next moment, the mechanical arm flew up and down, attaching pieces of white armor to his body and completing the fixation.

"Hiss ......"

The hatch opened again, and Chen Yu stepped out and looked at the camera.

"After learning about the existence of a black hole, I used the portal's location pattern to look for it, but failed. There is no information about the position and orbit of this black hole in the database, and I don't know its five-dimensional coordinate values, so it is difficult to find it. ”

"But over the course of a week, I've figured out a way to do it. ”

Walking to the portal, Chen Yu summoned a virtual earth projection, shrinking, shrinking, and shrinking again, and finally reducing the size to the entire solar system.

"That is to go to a planet like Sedna, which is affected by a black hole, feel the gravitational pull of the black hole, and determine the bearing. ”

As he spoke, he slid the projection and found a pink asteroid, Sedna.

"This is it. ”

"Buzz!"

Five seconds later, the space inside the metal arch fluctuated for a split second, and a pink planet appeared in front of more than seven million viewers.

The road to death is about to begin.

I wonder if I should be glad to be able to see a black hole with my own eyes in my lifetime......

What exactly is a black hole?

All I care about is the asteroid that is about to hit me.

Can you blow up with a nuclear bomb?

Sit back and wait for the UP Lord to save the world......

"Hoo ......"

Taking a deep breath, Chen Yu calmed down, stepped out of the portal, and entered hundreds of millions of kilometers of space.

In an instant, the noise in my ears disappeared.

I could only hear the beating of my own heart.

"This is the Sedna asteroid. No. 2003 VB12. With an average distance of more than 80 astronomical units from the sun, it is the farthest asteroid ever discovered. Of course, more than 20 years later, mankind will also discover an even farther asteroid 'Gisela', that is, the planet that was dragged by a black hole and thrown into the inner solar system 25 years later. ”

"But I think it's better to call it Tanatos (the name of the god of death) instead of calling it Gisela. Because human civilization is likely to be hit hard by it. ”

"Sedna, one of the reddest objects in the solar system, is made up of water, methane, nitrogen, and Torin. That's not what we're aiming for this time, just a brief introduction. ”

As the words fell, Chen Yu ignored the pink world under his feet, turned his head to look into the deep sky, looking for the traces of the black hole.

"Inside my helmet, there are a lot of values on display, and a few of them are the gravitational changes around me. The largest source of gravity is undoubtedly the Sedna asteroid below, followed by the second largest source of gravity is the Sun, and the third largest source of gravity ......"

Under the gaze of the ball official, the astronomical community, and seven million spectators, Chen Yu suddenly raised his hand and pointed in a direction!

"There!"

The camera pans to the deep darkness of the sky.

Nothing but darkness.

"That's the outer side of the solar system, Jupiter and Saturn aren't in their direction, and they're not on the ecliptic plane......"

"Looks like we found it easily. ”

"Black holes. ”

T ......

Black holes are invisible, and can only be found by gravitational methods.

The accretion disk of a black hole is luminous!

Apparently this black hole does not have an accretion disk. (Doghead)

Lying on the bed, creepy.

Why look at black holes? Hurry up and solve that asteroid!

The existence of black holes must be confirmed first, otherwise everything is just empty words of the anchor.

I'm already convinced......

"Whoosh-"

Turning on the plasma engine, Chen Yu flew into the portal, returned to the hall of the island-building engineering ship, and quickly operated in the virtual projection.

"Now that you've determined the position of the black hole, now you just have to go in that direction......

Between words, he adjusted the angle and distance of the space twists and turns, and clicked to dock.

"Buzz!"

The waves fell, and the pink planet inside the portal turned into pure black space.

Chen Yu walked out of the camera, took a large rock that had been prepared a long time ago, and gently put it into the portal: "I don't need to explain the danger of the black hole, for the sake of safety, I can only try to find a suitable critical point." ”

"These rocks are how I test the tipping point. Judge the distance between me and the black hole by the speed at which the rock is dragged by the black hole. I'll admit that this is a ridiculous and ridiculous approach, but it does work. ”

With a rare self-deprecating shrug, Chen Yu put the rock in the membrane of space and space and let go.

Then, the loose rock was sucked into space and flew into the darkness ahead with a whirl.

"Sure enough, there was a black hole in front of me. ”

Chen Yu's voice became serious in vain, he took off his hand shield and slid the watch screen: "Now, I need the help of the Aerospace Research Institute, and you must be watching the live broadcast." In the previous interactive live broadcast, I gave you private chat permissions, and now I ask you to calculate the distance between me and the black hole according to the speed of the rock's flight. The mass weight of the rock is about ten kilograms. ”

When the words fell, a private message from the Institute of Aerospace Research came.

"We already know the mass of the black hole, the quality of the rock is not important, please wait a moment, the calculation is being made. ”

Seeing this private message, Chen Yu nodded: "Okay." ”

......

Beijing, Institute of Aerospace Research.

"Quick! Calculate quickly!"

The old dean slapped the table and shouted: "The mass of the black hole is one hundred and twenty-five times that of the earth, and there can be no mistakes in multiple sets of calculations!"

The researchers in the hall immediately began to calculate busily and nervously.

"The black hole has a mass of 125 times the Earth, a rock diameter of about 35 centimeters, an initial fall velocity of about nine meters per second based on the reduction amplitude, a gravitational formula F=GMr2, and a gravitational constant of 6.67×1...... Availability......"

“......”

“......”

The sound of dense keyboard tapping and the sound of pen tip recording were connected, and half a minute later, multiple teams came up with similar data at the same time.

"One and a half million kilometers. ”

"Dean, 1.1 million kilometers. ”

"Here are 1,250,000. ”

"One and a half million kilometers. ”

"0.4 light years...... Wait... Wait until we recalculate. ”

The old dean didn't have time to reprimand the last group, and immediately sent the results of the calculations.

......

"One and a half million kilometers. ”

After receiving a private chat reply from the aerospace institute, Chen Yu put on his hand armor, moved the connection point of the portal forward by a million kilometers, and clicked to connect.

"The result given by the Space Academy is 1.2 million kilometers, and to be on the safe side, we will move the position of the space gate forward by 1 million kilometers. ”

Five seconds later, the docking was successful.

Inside the portal, there is still a dark and deep place.

Perhaps knowing that the distance from the black hole is only 200,000 kilometers, all the viewers in the live broadcast room felt a cold fear in their hearts.

Black hole.

One of the most extreme celestial bodies in the universe.

Human beings are finally going to be "touched" up close......
