Beneath Deep Space

Yu Yifeng is not a pure astronomer, nor a physicist. During his long career in power, he has been involved in all aspects, and what he has learned is miscellaneous.

However, his knowledge is very broad, which is also a big benefit.

He thought carefully: "If you want to discover the Big Bang, you must at least have the red shift of stars, or microwave background radiation. Or other things that I haven't thought of yet..."

"But now that the universe is dark, all this information seems to have been lost. What should we do?"

After thinking about it, he was a little troubled, and there seemed to be no good solution.

He could only lament that he didn't know enough. It might be easier if an astronomer was asked to do this question.

But he doesn't want to quit directly. If you sell an experience ticket, you can get 1 point, which is more than one hundred tons of antimatter. He didn't want to waste it, being such a prodigal.

"...This question is not purely scientific, but more sociological." Yu Yifeng had a flash of inspiration and grasped the key point.

"The question requires me to create a civilization, and then let this civilization discover it, instead of letting me explore here by myself... If the level of this civilization is high enough, there are enough talents, and the wisdom is greater than mine, it should be... OK?"

"Try it!"

While thinking about it, a nebula 10 light-years in size suddenly appeared in the starry sky. They are the only matter that Yu Yifeng can come into contact with in this dark universe.

"In the era of heat death, matter is really precious." He sighed secretly.

This group of nebulae is like a group of stagnant water, not large enough, and they are in a state of gravitational balance with each other. If there is no interference, it will continue like this until all the protons decay.

"Do you have to create everything yourself? Starting from a nebula... this game is quite realistic."

Yu Yifeng's heart moved and he felt like he had become "God".

Everything must be born in this darkness.

"Anyway, we have to create an intelligent race first before we can talk about the next thing. Without an intelligent race, how can we make discoveries?"

"God said, let there be light!" He recalled certain contents in the Bible, and smiled and recited silently in his heart, feeling that it was meaningful.

"To create an intelligent race, you must first have a star!"

With a wave of his hand, he began to push the nebula, breaking the gravitational balance.

Sure enough, this huge nebula measured in light years was pushed by him!

"...I really feel like I am God." Yu Yifeng was surprised. He didn't know how this feeling came about, but it turned out to be completely real.

"Is the technology of the brain in the vat so advanced? Can it directly stimulate my senses?"

Soon, this nebula began to change under the impetus of Yi Feng. Because of the conservation of angular momentum and the mutual attraction of gravity, the rotation of the collapsed nebula rapidly accelerated. The atoms in it collide with each other more frequently, converting kinetic energy into heat energy.

Yu Yifeng's body is invisible, but very powerful. He feels like playing with a top, whipping a ball of cotton, which is like "power can work wonders."

"Push Nebula, effortlessly. This is...God mode!"

He pushed faster and faster, and the nebula became hotter and hotter. Under the influence of gravity, gas pressure, magnetic field and rotational inertia, a dense protostar gradually formed in the center over millions of years!

"It's really amazing..." Yu Yifeng sweated and suddenly felt the physical exertion.

And in this process, a lot of astronomical knowledge needs to be used.

Stars of different masses will have different luminous intensity and lifespan in the future. He does not want to create a huge and short-lived blue star, nor does he want to create a useless red dwarf star.

The main target is still a yellow dwarf star that is exactly the same as the sun.

"It seems that this 'God' also has limitations. There is no way to modify the specific physical rules. It is not truly arbitrary. It still has to be based on the laws of nature..." Yu Yifeng has already discovered this setting.

The thermonuclear fusion in the center of the protostar has not yet formed, and it is still not a true main sequence star.

"So you have to light a fire. The way to light a fire is of course to increase the mass."

His eyes can read the mass of the protostar and try to control it so that it is close to the mass of the sun.

The nebula continued to accrete material. As the material increased, the internal pressure increased. Suddenly, the protostar emitted light and was ignited!

In this dark universe, a dim light point appeared, the only light point!

"It's really not easy." Deep in Yu Yifeng's heart, there was a slight sense of accomplishment. This point of light turned out to be the only point of light in the observable universe. The era approaching heat death is really scary.

"Under such circumstances, who would have thought that trillions of years ago, under the deep sky, there were stars gathering and countless civilizations? It seems that our universe is actually pretty good."

The warm light seemed to illuminate his entire heart, filling him with energy.

Of course there is a reason for him to do this. After all, light-based life is the mainstream in the universe, and it is what he is most familiar with. He doesn't understand other messy lives at all, nor does he know how to create them.

If you want to create intelligent life, you must first have a sun. This is a natural idea for Yi Feng.

Of course it's not enough to fabricate stars, you also need planets.

Of course, he started copying the previous solar system again.

The inner solar system is about a distance within 4 astronomical units. Because it is too hot, it is difficult for small molecules such as water and methane to gather in this area. Therefore, terrestrial planet embryos are formed from high-melting point, high-mass materials, such as iron, nickel, Silicates etc.

Within 100,000 years after the formation of the sun, they grew to 0.05 Earth mass, no longer had enough raw materials, and began to stop gathering.

Beyond 4 AU, between the orbits of Mars and Jupiter, the icy compounds remain solid due to cooler temperatures.

Therefore, the planet here has a lot of ice and methane.

The young Sun had a steady and strong new wind. Uranus and Neptune were formed after Jupiter and Saturn, after the solar wind blew away most of the disk material.

The result is that...the two planets have relatively small concentrations of hydrogen and helium, no more than one Earth mass each.

Well, Yu Yifeng discovered that his god is indeed not very powerful. Apart from being extremely powerful, he can only exercise his power according to the rules of nature. For example, it would be possible to speed up time, create certain accidents, etc.

But he has no way to suddenly change the gravity of a certain area, nor can he significantly change the formation of stars.

If he wanted to use his strength to create a miracle, or if he wanted a Jupiter to forcibly appear in the position of Venus, the consumption of "physical energy" would accelerate rapidly, making it...impossible for him to complete these tasks.

"...Natural rules and the setting of physical strength are the main constraints. However, physical strength will recover with the passage of time...Don't worry too much." Yu Yifeng thought to himself.

After all the planetary structures were completed, he finally breathed a long sigh of relief. He was tired, so tired.

Because of his forced interference, eight planets actually appeared!
