On this day, in the command room of the Homeland, Yu Yifeng was discussing the problem of dark matter bias shield with several professors.

Yu Yifeng desperately wanted to know whether this thing was reliable or not, and whether it could be reversed.

"No, Captain, we've really done our best. There are too many theoretical parts to be deciphered......"

An expert looked through the information on the computer and said with a bitter face: "Captain, our understanding of space is too limited, and we have not even realized artificial gravity and anti-gravity, how can we reach the sky in one step?" This dark matter bias shield technology, which combines multiple theories, is not only in the category of L2, but also an all-round application of space technology......"

"I think you have to achieve artificial gravity and anti-gravity before you can think about the higher level ...... later."

Yu Yifeng frowned, looked at the various materials that had been analyzed so far, and sighed.

He also understands this kind of thing, which is equivalent to the relationship between the difference machine and the Turing machine, even if there is no direct cause and effect, there is a mutual connection.

Moreover, science and technology will not be accelerated because of his will, and there is no way to urge, wisdom is counterproductive.

"Artificial gravity vs. antigravity...... I'm finally facing this problem. ”

There is a natural gravity in the Noah, and people don't need to worry too much about it at all. And the "gravity" of other flagships, which can be replaced by centrifugal force, can be simulated.

But no matter what, centrifugal force is still not true gravity, and there is a difference between the two.

Just thinking about it, he suddenly thought that when he was on Mars, it seemed that through Noah's "floating", he had deceived the green light civilization and made the other party mistakenly think that it was anti-gravity technology.

Unexpectedly, people have developed until now, and they still have not achieved anti-gravity. It can be seen that this technology is indeed quite difficult.

"Is artificial gravity versus anti-gravity possible?" He couldn't help but ask.

"Of course it's possible!" The expert thought for a moment and explained seriously: "Centrifugal force is actually an alternative to gravity. ”

"It's so hard to fully create true gravity, and it can involve extra dimensions. According to our current theory, gravity may not have been as weak as it was detected, and it was only after penetrating multiple dimensions from the high-dimensional space that it was weakened layer by layer and became what it is now......

"But we can't directly interfere with the real extra dimension, and it's hard to create gravity...... For now, the truth about gravity has not been fully understood. ”

The existence of extra dimensions, that is, the space of higher dimensions, has been observed in current high-energy experiments with massive particles arranged in a series of equal differences, which indirectly proves the existence of extra dimensions.

"The world is far more complex than you think. Maybe it's inherently complex, rather than concise ......"

Seeing Yu Yifeng's thinking expression, the professor said again: "Actually, artificial gravity and anti-gravity are two different technologies. Each of these has several different development paths. ”

"Artificial gravity, for example...... In the first method, some exotic matter can be used to distort a steady-state space, and isophase simulation of mass-induced space distortion. ”

"Second, of course, it is the manipulation of gravitons, and if the nature of gravity is indeed gravitons, we can construct a superfluid of gravitons modeled after the superflow phenomenon in condensed matter. If this superfluid is encircled around a finite area that we want to shield, then the graviton flow through this area can be short-circuited under normal circumstances, thus achieving a localized shielding ...... This is equivalent to achieving anti-gravity. ”

"Third, establish a unified equation for the mutual transformation of the four basic forces, and use electromagnetic force to forcibly create a gravitational force. But we think it's too difficult, and even if we do, we need to be able to convert to each other within a certain range. For example, the exaggerated energy level ......"

"Okay......" After hearing this, Yu Yifeng was silent for a while.

He thought about it and found that either way it would be extremely difficult.

With today's technology, the difficulty has skyrocketed, and it has become more and more difficult to climb. It seems that there is only one point of technology that can be developed in three-dimensional space, and the rest, including gravity and tachyons, all involve the legendary "extra dimension".

"The first way to use dark matter to intervene in space may sound a little simpler, but it can't be done overnight."

The expert smiled and said: "Captain, if you are really in a hurry to fly to the trading market. We believe that ...... The safety of these eight bias shields is still relatively high, and when loaded on our homeland, it can travel at a hundred times the speed of light. ”

Yu Yifeng did not express his position.

He has his own ideas.

A hundred times and five times, it is indeed of different magnitudes. If you travel at a speed of 100 times the speed of light, the distance of 2,000 light years can be reached in only 20 years, which is an acceptable range.

If it's five times, you have to rely on the hibernation chamber to fly over slowly.

After a while, he asked, "But there are only eight such devices, and they can't be split for use." It's impossible for our other flagships to achieve a hundred times the speed of light, so don't you want to leave it behind?"

Professor Ding Yidong, who was standing on the side, said: "Of course not, how can these big spaceships not be ...... So we planned to combine the four flagships directly. ”

"The range limit of this dark matter deflection shield is two hundred and twenty kilometers, which is completely capable of encircling four flagships. In this way, everyone can fly together. ”

Yu Yifeng looked at the analog image on the video and frowned.

The four ships are put together like building blocks, and they can be separated when they want to.

But the way this model looks is really a bit weird. It's not as cool and ingenious as "Transformers" at all, but it's a bit like using a few steel bars to forcibly tie the spaceship together, which is just rough.

This must be Professor Ding Yidong's masterpiece.

He exhaled, knowing that this was to reduce the amount of work, that it was impossible for people to stay on this white dwarf for a long time, and that it was impossible to build a larger flagship.

"Well, it looks like all the ships are going to be remodeled again. However, the amount of work is acceptable, but the whole splicing looks a little ugly......"

"The safety test of the dark matter bias shield will continue, thank you for your hard work."

So this time, the main project is the splicing and transformation of several spaceships, the problem is not very big, and it does not need a large rest, and it can be completed in about a year.

Next, Yu Yifeng finally heard a very good news.

"Captain, we've cracked some of the information in the commercial ship!"

Almost all of the electronics of the commercial spaceship were locked, and only a small number of parts were destroyed before the lock-up, but instead became useful.

In the years that people have been searching for spaceships, they have searched over and over again, and these data have become the most expected.

Quinton couldn't theoretically have come out of boredom to modify these things.

But the information coding of this batch of military equipment is very strange and still difficult to decipher, and it took up to a year for several scientific teams to urgently tackle the problem, and it was not until today that a mathematician successfully took it.

After Yu Yifeng got the news, he immediately notified all the senior management of the Noah, plus a large number of scientists, and began to sort out this part of the information.
