Chapter 207 Touching...the Black Hole (Part 2)

On one side, is the deep sea of ​​the Earth's Pacific Ocean.

On one side, is the edge of the solar system a few hundred astronomical units away.

A door connects the spaces of the two places.

Standing at the other end of the portal, Chen Yu picked up the second rock, paused for a moment, and threw it into the space membrane with his hands.

In just 20 seconds, the rock with a diameter of more than 30 centimeters spun and disappeared, falling into the terrifying darkness...

"The direction is right, the black hole is not far ahead."

Taking off the hand armor again, Chen Yu glanced at the private message on the watch: "The research institute sent over the second calculation result, the gravitational acceleration of the falling rock is 2.2 meters per second, and the distance from the black hole is within 150,000 kilometers. There's still part of the acceleration that I push out."

"So……"

Putting down his watch, Chen Yu looked at the camera: "Keep moving forward."

"One hundred thousand kilometers!"

In the dense barrage in the five live broadcast rooms, Chen Yu calibrated the virtual projection position and advanced the portal to within 20,000 kilometers of the black hole.

When the notification of successful docking sounded, he immediately took out a rock with a diameter of one meter and threw it into the darkness inside the portal.

This time, the rock "falls" extremely fast! In just three or four seconds, he disappeared from the sight of Chen Yu and the audience.

[Fuck! Gone? 】

[Is the acceleration too scary? 】

[It’s nothing scary, and it’s not a big black hole. After all, it is only more than one hundred times the mass of the earth. 】

【Obviously a disaster is imminent, but I always want to call 666...】

[Ibid. 】

[It is now possible to confirm the existence of the black hole, otherwise with this acceleration, it is impossible not to see the surface of the planet. 】

[Why didn't the gravity of the black hole suck the anchor away from the portal? 】

[Please rewatch the anchor's first live broadcast video. 】

[There are 300,000 deposits, if UP master can't save mankind, I will take my family to enjoy it. 】

[When the whole world is in chaos, you still enjoy it? Flight booked. 】

[I have sold the house. (Smile)】

【Calm down...】

...

In aerospace institutes, researchers have obtained more and more data, and the calculation results have become more accurate.

"Mass 7.45625000E+26, acceleration due to gravity is 20.72 seconds..."

"Forty-nine thousand kilometers!"

"Forty-nine thousand kilometers!"

"Me too."

The old dean got the data and immediately forwarded it: "Mr. Wang, the distance between you and the black hole is only 49,000 kilometers."

...

Inside the island-building project ship, Chen Yu received the message and displayed the watch screen in front of the camera: "There are 49,000 kilometers left, and the direction is correct."

"This distance is already very short, which is about a little more than a circle around the Earth's equator."

"Because the flying speed of my protective suit is at least kilometers per second in a vacuum, which is far greater than the escape velocity at this distance, so I should still be able to move forward a little bit."

"Keep going! Twenty thousand kilometers!"

【……farewell. 】

【farewell. 】

【farewell. 】

【farewell. 】

Operate the portal to "advance" 20,000 kilometers.

Inside the door, it was still pitch black. Lack of reference objects, as if the distance in space has not been shortened in the slightest.

"Whoosh—"

The fourth rock flew in and disappeared in the blink of an eye...

The calculation results of the Aerospace Research Institute came again.

"The acceleration of the rock is 59.16 meters per second, and the distance from the black hole is 29,000 kilometers."

After confirming the distance, Chen Yu stretched out his hand to slide the virtual projection, and explained casually: "There are less than 30,000 kilometers left. If the earth is nearby, the terrifying tidal force will tear the earth apart instantly. On the scale of the universe, it is really It's close at hand. Then move on..."

"Twenty thousand kilometers!"

With the fifth docking of the space twists and turns, the portal suddenly lit up with orange light.

This represents the first level of warning.

The space film is torn by a strong gravitational force...

"There are three layers of alarms for the portals in the star system, orange light, red light and black light. If it reaches red, it means that it is extremely dangerous, and if it is black, it means that space connection cannot be established. So the current orange warning, everyone, don't be too nervous."

With that said, Chen Yu picked up the fifth rock and threw it into the dark abyss.

moment.

The rock disappears.

The speed of inhalation far exceeds the upper limit of human dynamic vision.

Taking a step back subconsciously, Chen Yu looked at the camera: "Can you calculate the speed of the rock? And how far is it between me and the black hole?"

Ten seconds later, the private message interface sent a reply from the research institute: "I am very sorry, Mr. Wang, the video recorded by your camera was received by us, and there is not much information left. If it slows down to a certain extent, it will become blurred, and the gravity of the rock cannot be accurately calculated. Acceleration. Can you come to the research institute and take away a group of experts and professional equipment?"

Seeing the reply, Chen Yu hesitated for a while, then nodded: "Okay, I'll go now."

After the words fell, he collected the current space coordinates, and then connected to the Aerospace Academy in Beijing.

I saw the square inside the door, and there were already a dozen scientific researchers waiting in the cold wind with various tools, equipment, and notebooks, shivering.

"Europe!"

"coming!"

"Come in quickly, lithium batteries cannot be frozen."

"Bring the high stand! Hurry up..."

More than a dozen scientific researchers flocked here, and before they could say hello to Chen Yu, they busily set up high-frame-rate cameras and various computing equipment.

Everyone's face turned red with excitement.

Will the earth be destroyed?

Will human beings become extinct?

Does the universe exist?

In their eyes, has a relationship with them? !

black hole!

This is a black hole!

It is still a primordial black hole that can be observed at close range!

Just getting the acceleration data of gravity at different distances is a revolutionary breakthrough in the physics world...

"Mr. Wang...Mr. Wang, we are ready." A person in charge walked up to Chen Yu holding the weighed rock, suppressing his excitement.

"good."

After receiving the rock, Chen Yu didn't say much. He walked to the portal and adjusted back to the space coordinates. Under the joint focus of the floating camera and high frame rate equipment, he threw the rock.

"Whoosh—"

The rock was hidden in the darkness, not even a trace of light appeared...

"Beep!"

The ultra-high frame rate camera buzzed, and the researchers immediately exported the video data for intense calculations.

"The acceleration of gravity is 593.65 meters per second, a=GM/r...6.6726 multiplied by ten to the negative tenth power M-m/kg..."

"M=5.965×ten to the twenty-fourth power kg multiplied by 125..."

"The result is out!"

A middle-aged researcher jumped up and down, shouting excitedly: "9154730 meters away from the black hole! Accurate!"

"The mass of the black hole has also been accurately obtained." Another researcher was short of breath: "7.45625331E+26!"

"The escape velocity has also been obtained. At a distance of 9,154,730 meters, the escape velocity is 104,255.92 meters per second."

"One hundred thousand meters per second?!" Chen Yu was stunned suddenly: "Doesn't it mean that I can't escape once I go in?"

Hearing this, many scientific researchers were also stunned for a moment, and then a woman quickly explained: "Mr. Wang, this is not the case. You have fallen into the misunderstanding of escape velocity. Escape velocity means that when you reach this speed, you can be thrown out without power. Without power ! With sustained thrust, you'll be able to get out even if you're nowhere near that speed. As long as you're flying faster than you're falling."

"I see."

Chen Yu was stunned, and then said: "Then it should be possible to move forward?"

"Can, can, can!" ×14

All the researchers nodded like chickens pecking rice, staring at Chen Yu with sparkling eyes.

"That……"

Chen Yu vaguely felt that something was wrong, but still bit the bullet: "Go on, how many kilometers is appropriate?"

"Go forward another five thousand kilometers!"

"Will...will it be too much?"

"No." The middle-aged researcher stepped forward and patted his chest: "Please absolutely trust us!"

Chen Yu: "..."

...

(Note: All the data are calculated by myself based on the mass of the black hole, and each 0.1 has been calculated many times to ensure the truth. Thanks to the two book friends for their "brain power" and "calculation power" support, I hope it is not wrong 2333... ...)
