Yu Yifeng said: "The 240 towers are already capable of planetary curvature engine drive. This has been proven by the tests just now. So, we've got the ability to get out of here. ”

"How do you hide the traces of the planet's departure? Where should we go? ”

These two issues are the primary problems facing people.

The departure of an ordinary spaceship was silent. But this is not the case with a planet, where huge gravitational fluctuations are very conspicuous in gravitational detection equipment.

"Starting such a huge 'half-finished' curvature engine leaves traces of dark matter disorder." One of the experts was the first to stand up and speak.

These marks, like some footprints in the forest, are not particularly clear, and will slowly calm down over time.

But they do exist.

Based on these traces, it is possible to determine the direction of movement of the traveling star, so as to intercept it.

On the other hand, faster-than-light motion, because of the different angles of observation, is not impossible to observe, but the information is lagging and chaotic.

This has been well verified in astronomical observations over the years. Faster-than-light phenomena have been observed many times.

"If a spacecraft moving faster than the speed of light is observed directly behind its direction of motion, whether it is through gravitational waves or photon means, you can see that its speed away from it is still the speed of light...... Attention, it's not that it's impossible to observe. ”

“…… Combined with the traces of dark matter and thermal radiation, if the enemy arrives here in time, they can still deduce the direction in which we are fleeing. Although it was only in the direction, if there was a white dwarf battle star, in the same direction, it suddenly ran directly in front of our movement. A single gravity cannon can blow us out of the faster-than-light environment! ”

"Our curvature engine is not completely completed, the maximum speed, only three times the speed of light, is not fast, it can't run very long distances, and it is impossible to resist the gravity gun."

An expert in this field listed on the screen the various restrictions of curvature navigation. Combined with these conditions, the hearts of all the parliamentarians were slightly nervous.

The last hurdle for people to escape is not easy.

The same is true for Yu Yifeng, most of the time has passed, and the thought that the unknown enemy is likely to be on the way, he can't help but feel a sense of urgency.

"It's already come to this point, if it really capsizes, it's a sin......" He secretly thought in his heart, the prestige of the Pangu has risen significantly in these years, and it can be said to be a kind of work fulcrum for the new human race.

A spacecraft is small in size, small in mass, and has no gravitational waves, and it cannot be observed if it flies a light year away. But for a planet, these traces are relatively obvious. How to cover up the traces of gravitational waves, thermal radiation, and dark matter is a cosmic problem, and the new human beings have no way to do it for the time being.

At this point, everyone began to meditate.

After a while, Yu Yifeng frowned and took the lead in breaking the silence: "Even if we are only 3 times the speed of light and can't run far, we also need to leave as soon as possible, staying here is certain death." ”

"In the process, we can try to keep changing directions, trying to shake off each other, and the more we change directions, the more chaotic this trace becomes. At least, the enemy hasn't appeared yet, and we should still have time. ”

That being said, Yu Yifeng still felt unsafe. Although faster-than-light movements can easily escape pursuit, what they are discussing and pursuing here is a 100% success rate and the absolute safety of the population. This conventional way of circumvention cannot be said to be absolutely safe.

Even if humans are given 5 years to escape, they will only be able to escape a distance of 15 light years.

This distance is safe enough for an ordinary spaceship, but it is still far from enough for a planet.

It's only 15 light years......

No one knows how fast the White Dwarf Battlestar is, how strong the gravity cannon is, and how far it can reach. Once caught, maybe the entire civilization will be in great danger!

This question is like a dark cloud, hanging over people's minds and lingering for a long time.

It is precisely because the safety issue has not been solved that the entire Noah has not been migrated to the "Pangu" battle star. It's all about being ready to escape!

"Wait a minute!"

It was Dr. Rimbaud who spoke abruptly, "I've thought of a way......"

"The first is to take advantage of the information disruption brought about by faster-than-light motion. We can devise a method specifically ......"

The gravitational-wave telescope of the new humans has been in operation for so many years, and it has also observed all kinds of strange "moving" planetary spacecraft. Including all kinds of long "noodle" gravitational sources, as well as all kinds of strange phenomena flying upside down.

This kind of scene is caused by the movement "beyond the speed of light".

If you look directly behind the direction of faster-than-light motion, you will see that the speed of the spacecraft is still the speed of light. This is well understood.

Viewed from the side of the direction of motion, the situation is slightly complicated due to the different angles. Sometimes, you will see various discrete dots, which are slowly connected together, and divide into several sections like noodles.

There are even several "noodles" at the same time, some of them moving forward and some of them retreating, like wriggling worms.

And sometimes you will see the "noodles" constantly stretching, stretching, stretching out for several light years!

Of course, standing directly in front of the faster-than-light motion, the situation is different, there is no way to directly observe this movement, and the information is greatly delayed. This kind of situation has been encountered by the new humans several times, and when they attacked the Antek civilization, they took advantage of this situation.

"Gravitational waves have the same speed as photons, and as a kind of information transmitted at the speed of light, the situation is similar." Dr. Rimbaud said, gesturing his hands. "In the past 600 years, we have observed 6 times a faster-than-light planetary spacecraft, and 2 times because of the large confusion of data, it is difficult to judge the direction of motion, and the length of the other party's gravitational source is several light years...... There are also three cases when there is an ambiguity in judgment, which may be in several directions.

"There is one last time, which can be clearly judged."

"From this, we can design a special trajectory to disrupt the other party's observations. At least when solving mathematical equations, there are multiple feature solutions......"

"When the other party comes here, they will definitely observe our current place, as long as they don't feel too comfortable knowing where we're leaving."

This is a very practical statement, and it is more desirable to design a route that disrupts the line of sight than to take random turns.

Many numerical experts are also frowning and meditating, judging the time when the other party may come, and what they may observe under different sailing trajectories.

This was followed by a statement by astronomer Professor Thomson: "I observed another planet similar to Mercury 8.9 light-years away. Its quality data is slightly less than that of our battle star...... The difference is no more than 3%. Can this planet mislead the enemies who come to it? ”

“…… I think it's possible to use the ordinary engines of a large number of spaceships to forge the trail of dark matter disorders. At the same time, we designed our escape route to get as close to that planet as possible. ”

Everyone was silent for a while, how to say this plan.

This kind of imitation, or "misleading" the other person, is actually very difficult...... 8)
