"Mr. Zhou, the results of the investigation into the fall of the space station have come out."

Hao Xiaoxi walked into the office.

She gently put the document on Zhou Zhezhi's desk, and then said worriedly: "Teacher Zhou, the Academy of Sciences said that they have found some extremely abnormal situations. ”

Zhou Zhe raised his head slowly.

He picked up the document and only turned a few pages, and Furui Wubo's eyes changed subtly.

"Let's go to the Academy of Sciences."

He thought for two seconds before saying.

Hao Xiaoxi was stunned for a moment, she hesitated: "Now?" ”

"You have an important meeting in the afternoon......

Zhou Zhe stood up straight, and said in a hoarse voice: "Every meeting here is important, but this matter is more important than the meeting here." ”

Hao Xiaoxi was stunned.

She thought to herself that the space station had fallen, and it was useless to do anything now, what did the Academy of Sciences report in the document, it was so urgent that Teacher Zhou couldn't even wait for an afternoon.

It is better to put off an important meeting on the agenda than to rush to the Academy of Sciences immediately......

She had never seen Teacher Zhou so urgent.

Hao Xiaoxi came back to her senses, and she said with a straight face: "Then I'll arrange it for you now." ”

She respects Zhou Zhezhi from the bottom of her heart.

So although she was a little confused, she didn't put forward any opinions, because she believed that Zhou Zhezhi had a valid reason for doing anything.

"No arrangement, just go." Zhou Zhe said slowly, "The scientists are already waiting for me there." ”

Hearing this, Hao Xiaoxi was slightly stunned.

She is Zhou Zhezhi's assistant.

She did not receive an invitation from the Academy of Sciences to Zhou Zhezhi, but Zhou Zhezhi said that the scientists were waiting for him.

Did the Academy of Sciences put the invitation in the document?

Hao Xiaoxi was puzzled.

The Academy of Sciences has a lot of work, and scientists are busy in the lab day and night to make sure that the two projects go smoothly, working between theory and data.

What exactly did they find this time?

What made them take time out of their busy schedules and take the initiative to ask Zhou Zhezhi to go to the Academy of Sciences to discuss, and they were sure that Zhou Zhezhi would come, and deliberately made time to wait for Zhou Zhezhi.

Zhou Zhe said in a hoarse voice: "Something beyond our understanding has happened. ”

......

"We can't explain why this is happening, it's against the most basic physics knowledge, that's why we invited you over and reported to you in person."

Several physicists stood in front of Zhou Zhe.

Behind them was a huge screen that looped the fall of the space station, marked with a number of physical parameters.

Velocity and acceleration are highlighted in red.

"According to common sense, the fall of the space station should conform to the classical physical model of a falling object, that is, the accelerated motion under the dual action of the earth's gravity and air resistance."

The scientist said with a solemn face.

"But when we studied the video of the space station falling, we found that it was not at all, and the deviation was exaggerated, and we thought that something must be wrong!"

Zhou Zhe listened carefully.

The scientist turned around and typed a few keys on the keyboard, and the image on the big screen behind him jumped to the time when the space station exploded, which is when the space station began to fall.

"If we follow the classical physical model of a falling object from a high altitude, we can make a graph of the falling speed of the space station......"

"This is the picture."

The scientist tapped the keyboard again, and a graph appeared on the large screen behind him, showing the speed of the station's fall versus time.

As can be seen from the figure, at the beginning, the falling speed increased rapidly, reaching tens of meters per second at once.

But as time goes on, the air resistance increases, and the falling velocity, although it is still increasing, is increasing more and more slowly.

This is a smooth curve with a gradual increase in slope.

"It's a theoretical model, and that's how it should be!" The scientist grimaced, "But if that's the case, we don't need to ask you to come over......

He tapped the keyboard again, and an extra line appeared in the graph on the big screen.

"Here's what it actually is."

Curves that symbolize the actual situation...... It should be said that it is a broken line, which is clearly divided into three stages.

In the initial drop stage, it is basically consistent with the theoretical model, which is a smooth curve of ascent with a large slope. In the middle acceleration phase, its slope suddenly disappears and becomes a horizontal straight line; At the end of the phase, its slope returns, but in the opposite direction.

"To put it simply, the space station just started falling quite normally, which is exactly what science expected."

The scientist sighed and said, "I don't know why, the acceleration suddenly disappeared, and when it was about to land, not only did it not accelerate, but it also began to slow down." ”

"This line ......"

"I'm afraid Newton can't explain it clearly!"

There was a hint of exhaustion on the scientist's face.

Their entire team tossed and turned for more than a week to study the fall of the space station, and in the end, not only was they physically and mentally exhausted, but even their scientific outlook was greatly criticized.

Hao Xiaoxi next to him opened his lips slightly.

She was amazed.

Her physics is not very good, but even if she is just an ordinary person, she can understand that there is an unscientific big problem in the fall process of the space station at this time!

"What's going on?"

She asked nervously.

The fall of the space station itself was already terrible, and as a result, strange phenomena occurred in the process of the fall that cannot be explained by science.

The Ark project has failed, and the next step is to verify the feasibility of the mountain-moving plan and the month-by-month plan, if this phenomenon happens in the validation experiment......

Hao Xiaoxi couldn't imagine the consequences.

However, in the face of Hao Xiaoxi's question, the scientist's eyes showed a touch of helplessness.

"I don't know."

He replied bitterly.

"But to achieve this effect, you need to apply a force in the opposite direction of gravity to the space station when it falls."

"The mass of the Ark space station is 2.1 million tons."

"That is to say, when the space station fell, an extra force equivalent to 2.1 million tons was applied to the space station out of thin air, continuously preventing it from falling."

"But we didn't observe it at all."

The more scientists speak, the lower the voice.

2.1 million tons!

Uniform output!

Continuous!

Even if you put a nuclear bomb and firecracker under the space station, you won't be able to achieve this effect!

They watched the video countless times, and the attitude of the space station when it fell was so natural that they couldn't see that a force of this magnitude was acting on it.

It's not scientific!

Zhou Zhe looked at the big screen and was silent for a long time.

After a while, he glanced at the camera overhead, and then slowly spoke: "Why is this happening, what caused the space station to fall so strangely?" ”

He asked meaningfully, "You know what?" ”
