Spirit cultivation and immortality, how do you control an aircraft carrier?

"Of course it's the M87*."

Professor Gu gave a clear answer almost without hesitation.

Those who were aware of the situation nodded slightly in agreement.

Shen Huang, on the other hand, didn't know much about astronomy, so he didn't understand some of it.

Fortunately, Professor Gu quickly provided an explanation.

"To date, we have discovered many central black holes, but apart from those whose existence cannot be confirmed, only three are truly representative: the largest, the closest, and the clearest observed."

The largest is TON 618, the most terrifying and powerful celestial body we know of, with a mass of 66 billion times that of the Sun. Unfortunately, TON 618 is extremely distant, 10.4 billion light-years away. With our current astronomical observation methods, we cannot directly obtain any definitive photos or images; we can only indirectly confirm its existence. It can be said that it far exceeds the limits of current observation, and even the figure of 66 billion light-years may not be accurate.

Shen Huang felt a little regretful upon hearing this.

But as he said, merely knowing the concept without being able to observe, without data, and lacking cognition will greatly increase the difficulty of visualization, making it impossible for people to visualize.

"The other two are the supermassive black hole at the center of the Milky Way, Sgr A, and M87* at the core of the giant elliptical galaxy M87 in the Virgo Cluster. These are the only two black holes that we can 'see and photograph'."

Professor Gu paused slightly, a smile spreading across his face: "Although the supermassive black hole at the center of the Milky Way is closer to us, only 2.7 light-years away, its size is on a completely different scale compared to M87*, which is 5500 million light-years away. One is only four million times the mass of the Sun, while the other is six billion times the mass of the Sun! Adding to this other factors, observing M87* is far less difficult than observing Sgr A. It was even the first image of a black hole taken by humankind, and it remains the most precise, complete, and physically detailed image of a central black hole!"

At this point, everyone understood why Professor Gu gave the best advice without hesitation.

Within the directly observable central black hole, M87* not only far surpasses Sgr A in size and intensity, but is also easier to observe, allowing for the acquisition of more patterns, data, and information, making it more conducive to visualization.

There's basically no need to choose anymore.

The mass of TON 618 is only ten times that of M87*, which is not a significant difference on a cosmic scale.

"Then M87* will do." Shen Huang also made his decision and typed, "I need very detailed information, including pictures, various data, cognitive introductions, and preferably virtual images simulated from real images, as realistic as possible."

"Please rest assured," Professor Gu chuckled, a hint of pride in his voice. "If we're comparing chip manufacturing, we still have a considerable gap to close with the world's top players. But when it comes to astronomical observation, our country is already at the pinnacle. The observation of M87* has been a crucial project that we've been continuously advancing. With some resource exchanges, I'm fully confident that we can deliver a world-class result!"

"No, more than that," Elder Li said from the side. "If it really succeeds, or plays a significant role, the significance of astronomical observation will be far greater than it is now. We will significantly increase our investment!"

That's right, if it really works, the country will definitely not hesitate to invest in it!

In fact, as Shen Huang took the first step and obtained the cultivation technique, especially after returning it, the importance the motherland attaches to it will only increase further.

When necessary, it can even carry out large-scale strategic adjustments!

Shen Huang had long been deeply aware of this strategic determination.

"I will do my best to succeed!" he promised.

However, just as Shen Huang was about to make a decision, others spoke up and offered different opinions.

"I have a concern: when using celestial bodies from the cultivation world as objects of visualization, will there be any special considerations for cultivation?"

The questioner was a middle-aged man. He stood up and continued to explain, "For example, the great sun in the cultivation world is actually different from an ordinary sun. The possibility of visualizing the great sun and directly drawing power from it—if this advantage truly exists, can the absolute power of the central black hole in terms of existence and the non-transcendental level truly overshadow this advantage?"

These words surprised some of the people present.

However, even Professor Gu did not immediately offer a rebuttal.

This comparison, after all, involves areas where his knowledge is lacking.

Shen Huang was also pondering, while simultaneously examining the information about visualizing the Great Sun within the jade slip.

After a long while, he slowly said:

"At least the first stage of cultivation does not require a direct connection with celestial bodies, and it is very likely that it will not be necessary in the future. Otherwise, with the sky shrouded in gray fog, the value of this technique would be greatly reduced. Moreover, cultivating this technique still involves drawing spiritual energy from the surrounding environment. I did not sense anything special or unique to extraordinary power from that Great Sun Visualization Diagram. The only feeling it gave me was that it was vast, scorching, and radiating endless light, just like our sun."

After a slight pause, Shen Huang seemed to have confirmed his thoughts, and his tone became rapid.

"Secondly, I have just discovered that the cultivation world is still in the geocentric stage, that is, the sun revolves around the earth. I am not sure if this is a lack of understanding or if the cultivation world is indeed like this. Visualization requires firm understanding, which may cause me some confusion."

Then, the jade slip clearly states that visualizing the Great Sun is more suitable for talents with fire and yang attributes. I think I may not belong to either of these two categories, but I am more likely to have talents in the spatial domain! This is the most crucial reason.

Finally, I think the concerns raised by Comrade Bai Hao earlier have some merit. Since the moon in the other world has become a blood moon, can we really be sure that the Great Sun is still the same Great Sun it once was? Could it have developed consciousness, or is it being influenced by some deeper force?

Based on the above, I believe we shouldn't abandon the obvious and enormous advantages of a central black hole just because of concerns about its existence. Moreover, this is only considered as the optimal option; whether it can be successfully constructed is still uncertain.

Once these reasons are presented, there are practically no grounds for objection.

Absolute power in concept and actual size, matching talent, and unknown security.

Most importantly, there's Shen Huang's personal will and intuition.

There is no need for any further hesitation in prioritizing the central black hole M87* as the object of contemplation.
