"Zhang, don't tell me, these are all required for me to study?"

Hawking's expression was a little sluggish, and he typed out a sentence in disbelief: "You know, none of the questions you mentioned are questions that can be studied and confirmed by a generation or even several generations of scientists.

I'm sorry, Zhang, but if you ask me to study them all, I can't do anything about it.

At the current pace of scientific research, it is not enough to study these issues before I see God. ”

In the end, a hint of disappointment and gloom flashed in Hawking's eyes.

He was tied to China for a period of time, and as the world's top scientist, Hawking's access to information and freedom of personal speech were not too strictly restricted.

He also heard about Zhang Han and knew that the other party was a person whose interests were paramount.

If he can't give Zhang Han the value he needs, then his desire to stand up again may be shattered.

"No, I just need Mr. Hawking to study for me wholeheartedly these questions that I have raised.

Regarding the needs of research resources and researchers, I will do my best to meet them. ”

Zhang Han did not strictly require Hawking to study clearly, he said with a solemn face: "There is a news, I don't know if Mr. Hawking and Mr. Kip have noticed that Voyager 1 has been half lost.

Voyager 1's detection information is still being sent back from extrasolar space, but all the commands we sent in the past have failed.

And, when Voyager 1 turned its camera to the solar system, it also discovered the accident. ”

As he spoke, Zhang Han took out two photographs of the starry sky and handed them to Kip and Hawking respectively.

After taking the image handed over by Zhang Han, Kip and Hawking looked at it, thinking of what Zhang Han had just said, and their faces instantly became extremely solemn.

"Zhang, are you sure this is an image taken by Voyager 1 from outside the solar system, facing the direction of the solar system?"

Kip's pupils shrank slightly, and he turned his head to Zhang Han and asked.

"Yes, the images taken in front of the solar system, from the infrared spectrum to the ultraviolet spectrum, all the spectrum has been taken and collected. Zhang Han nodded.

"The solar system is gone?"

Hawking typed out a sentence, and the electronic synthesized voice could not express the emotions of the voice itself, but the other two people present still felt the unrest in Hawking's heart.

As astronomical researchers, Hawking and Kip have firmly remembered the images of the starry sky around the solar system, even the position changes with the seasons from moment to moment.

What Zhang Han handed over was the observation image of the starry sky in a certain direction before the era of source force and before the change of the rules of the solar system.

Due to the limitations of the technology of the last century, the image is not very clear, but it does not hinder recognition.

If this is an outward observation within the solar system, or if it is not directly facing the orientation of the solar system outside the solar system.

So this starry sky image map, except for a little change in angle and direction, there is no other problem.

However, now that Zhang Han is sure that this is an image taken outside the solar system directly facing the solar system, then the problem is big.

The background of the starry sky is fine, but the problem is that if you shoot directly in front of the solar system, the solar system, which should be the brightest and most clearly visible, disappears!

Disappeared without a trace, disappeared without a trace left!

"That's just one point. ”

Zhang Han's voice was a little heavy, and he continued: "According to the operation status of Voyager 1 itself, as well as the orbit of the meteorite observed by Voyager 1 outside the system, the gravitational pull of the solar system has disappeared. ”

At present, Voyager 1 is about 17 light hours from the Sun, 122 astronomical units, and has just left the heliosphere, which is the sphere of influence of the solar wind.

This distance is far from the range of the gravitational influence of the sun.

However, now the information fed back by Voyager 1, after careful calculations, found that the influence of the gravitational pull of the solar system outside the solar system no longer exists.

"The solar system, only in and out!" Hawking was silent for a while, and his eyes were solemn as he typed out this sentence.

According to the data provided by Zhang Han, there are various indications that light and gravity outside the solar system can enter the solar system and have an impact on the solar system, but everything in the solar system cannot go out.

The entire solar system is like an absolutely semi-permeable membrane that can be entered by the outside world, but cannot be exited inside.

Neither the gravitational pull of the solar system itself, nor all the light waves emitted in the solar system, can get out.

Kip put down the image in his hand and asked Zhang Han, "Zhang, when did this phenomenon begin?"

"I don't know, this phenomenon was only discovered by accident in the last few days. ”

Zhang Han shook his head and said, "But although it has only been discovered in the past few days, I think I am afraid that this phenomenon has already begun where the rules of the solar system have changed."

Therefore, we can not discuss the impact of the solar system on the solar system itself, and what kind of impact it will lead to in the rules.

Because according to the theorem of human existence, we can still discuss this issue here, which means that even if there are changes in the solar system, it will not cause direct harm to our human beings.

Now, what we need to solve is whether we humans can leave the solar system, and with the increase in the scope of human activities, this question must be clearly understood.

There is also the impact of this change in the solar system on the universe.

Will this one change expand to the entire universe, and if it expands to the entire universe, then what?

And, I have a hunch that the next change in the solar system should not be far off. ”

Kip's expression was very solemn, and he guessed: "The rules have been strengthened again?"

"The solar system only goes in and out, the matter and energy from the outside world are constantly coming in, the total amount of energy in the solar system is constantly increasing, and the source of the source era is also in the solar system.

So if you want to keep the solar system from collapsing, the next change in the solar system will definitely occur in a short time.

Maybe the rules will be strengthened again, or maybe the space or solar system rules will become larger, these are all visible speculations, but it is not certain which changes. ”

Compared with Kip and Hawking, Zhang Han has already guessed and speculated more possible changes in the future when he knows more about these things, when he knows more about these things.

"Zhang, do you have any feeling that the current solar system is developing and evolving in the direction of the beginning of the universe and before the birth of matter? ”

Hawking said his speculation, and he asked Zhang Han: "I think, this is the reason why you asked me to study what the state of the universe would be and what would exist before the birth of the universe before the birth of matter in the universe 1,000 light years in diameter." ”

"Yes, that's what I perceived. ”

Zhang Han nodded and said, "We all know that under certain conditions, time is relatively unequal.

From the Big Bang to the creation of matter in the universe, the time span we speculate on is very small and very short.

But none of us knows how long time will pass, in fact, in that period, relative to the existence of that time period. ”

PS: Regarding the setting of Voyager 1, some changes have been made here for the needs of the plot.

The actual Voyager 1, due to energy, has long been unable to complete the operations described in the article.
