Lao Niu came quickly, and arrived in Xichang directly on a military plane that night. He was joined by a domestic liaison officer from Taiyo, who is also currently in charge of the specific work of Taiyue.

This means that the discovery of "traces of engine jets on an asteroid" is really touching the hearts of the higher-ups.

Without too many pleasantries, Director Niu went straight to the point.

"There needs to be a specific ...... Models, or inferences can also be used. Director Niu drank a small half jar of herbal tea in one go, and stared at Ye Ming with a serious expression: "Then do a safety assessment, and when necessary, you may need to make a public science popularization and explanation." ”

Ye Ming also frowned, but still nodded.

In just two days, the news of the discovery of explosion marks on the asteroid spread all over the Internet, not to mention, almighty netizens even found and pieced together almost 100% pictures of the impact surface of the asteroid based on the live broadcast video.

And netizens, how can they be as rigorous as Ye Ming's group of scientists?

As a result, the news that there had been an alien spacecraft in the asteroid belt spread, and some people even added fuel to the fire that the asteroid belt's itinerary was broken by the alien spacecraft.

How do you dry it? The legendary Star Destroyer, of course, - aliens who arrived in the solar system thousands of years ago! It's definitely omnipotent.

Why is it said a thousand years ago? Of course, this is because no planetary star has been found in the asteroid belt since recorded human beings.

It's just that guessing, the vast majority of netizens are still looking forward to the asteroid research team to give a letter.

But this quasi-trust...... It's really hard to give.

Ye Ming pursed his lips and glanced at Director Zhang beside him and Professor Xiao, who specializes in explosive traces, before he said softly: "Although from a scientific point of view, we don't accept that it can be directly determined to be caused by engine jets - unless we can find the same traces in the asteroid belt." ”

After a pause, Ye Ming immediately added: "Of course, this probability is very small, because the asteroid belt is not like the dense scene where a stone hits it at every turn like film and television works, it is extremely empty." ”

"But in the long term and completely, we really should think of it as a legacy of an alien civilization entering the solar system."

"Here, we don't make assumptions about the genesis of the asteroid belt."

"So there are three possibilities at the moment."

"The first is that there was a civilization in the solar system at the beginning of the birth of human beings, maybe Mars, or Venus, of course, it could also be Earth, within Europa - here, we don't have any evidence, just guess."

"The second is that the civilization's vehicles have mastered extremely high speeds that can do interstellar travel." Ye Ming paused again as he spoke: "Well, to be precise, it must be faster than light." ”

Director Niu immediately asked, "Why are you sure it's faster than light?" ”

"If it is not faster than the speed of light, then the civilization in which the ship is located has a relative upper limit on the distance from us, and it is very likely that we will receive their signals, or simply observe them."

Seeing that Director Niu was still a little incomprehensible, Director Zhang explained on the side: "If it can't exceed the speed of light, the civilization where this spaceship is located is very likely to be next door to our solar system - because a spaceship that can't exceed the speed of light is going to travel interstellar, and it is unlikely to go too far." ”

Ye Ming also added: "From the modeling point of view, the jet flow of the model has an upper limit of distance, and according to the upper limit, we believe that the output power of the engine will not be much greater than that of the Yueyue, at least not exponential." And judging from the use of jet propulsion, the spacecraft should not be out of the realm of what we can imagine. ”

Hearing this, Director Niu breathed a sigh of relief and motioned for Ye Ming to continue.

"The third possibility is that this spacecraft is similar to the Invitation Moon Spacecraft, and it also uses a controlled nuclear fusion jet, and the level of civilization will not surpass us too much."

Director Niu's eyes lit up instantly, but then he was puzzled: "...... before that?" ”

Ye Ming knew that Lao Niu was referring to the third possibility and the second possibility was contradictory-similar to the Inviting Moon, which meant that it would not run farther than the Inviting Moon.

Even the most awesome civilization is unlikely to allow a spaceship to run for decades, hundreds of years to explore—unless the humans there live a hundred years, or time and space warp, the spaceship runs for hundreds of years, and the location of the civilization is only a day away, or so on.

But in that case...... It's too much.

"We discussed it a bit and planned to rebuild the black hole model." Ye Mingyan was concise: "Perhaps, this black hole does not conform to all the currently known black hole models, it is a combination of a black hole and a white hole. ”

"To be more precise, it's a bidirectional, stable wormhole."

As Ye Ming's voice fell, Director Niu's brows furrowed deeply.

He knew that Ye Ming was just enumerating all the possibilities as rigorously as possible from a scientific point of view.

"So, which one is most likely?"

Ye Ming raised three fingers.

Yes, while there are three possibilities, the first and the second are not yet verifiable – just like God.

It can be explained, but not confirmed.

But the third one, which can indeed be put into action, can be proven.

How to confirm it?

The black hole is there, and it was intended to drill it.

At this time, the liaison officer of "Taiyue", who had been silent and listening carefully, suddenly asked, "I have a question, when did it come?" ”

Ye Ming fell silent.

Half a day later, he gently gave a time.

"Perhaps...... 10,000 years? 20,000 years. ”

……

……

It's night, and there's a cool breeze.

Ye Ming and Director Niu walked side by side in the small garden of the space center.

Sitting in the moonlight, Director Niu looked up at the sky, and then he lit a cigarette with a click.

Ye Ming watched him swallow the clouds and spit out the fog, hesitated for a few seconds and then said softly: "I'll have one too." ”

"Don't you?"

"Here's one."

“…… Well, just one, don't get addicted. ”

Holding a cigarette, Director Niu lit the fire for him, Ye Mingmeng took a puff, but he was choked with tears in an instant, and immediately threw the cigarette to the ground, and stepped on it at the end.

Director Niu laughed: "Huazi, you are so wasteful. ”

Ye Ming exhaled a few heavily, put his hands behind his head, leaned on the back of the bench and looked up at the sky.

This afternoon, Lao Niu has already reported all the information.

Let's put it this way, a warship, maybe one or two thousand years ago, appeared in the solar system in the era of humans or tribes...... This realization is indeed a bit too shocking.

If you go in the past, there is really a civilization on the other side that is tens of thousands of years ahead of mankind...... So how far has it developed in the past 10,000 years?

At the very least, it has to be a stellar-level civilization, right?

It's the kind of resources that can easily use the resources of an entire galaxy, even a Dyson sphere or something, right?

Compared with human beings, it is estimated that they have arrived in Space City with the people of primitive tribes in Africa...... Such a gap, right......

How do you greet people?

Or do you really pin your hopes on the kindness of others?

Therefore, even Ye Ming, who derived the concept of "relics" from the system task, did not dare to make up his mind without a way back.

That's not to mention above.
