After saying that, I don’t know what it pressed? Suddenly, the front and rear up and down devices of the entire eggshell began to open the skylight and turned into transparent glass.
A medium-sized window just appeared.
And outside the window, there is actually the vast Milky Way.
For example, Qiongqi and Dabao, who were lying on the ground helpless, opened their eyes and looked at the magical universe above their heads. Then their pupils suddenly became larger, and the next moment they jumped up in excitement, "What is this?"
"
At the same time, they jumped on the seat, the window next to Bala, and also jumped on the window steps at the edge of the window. The two little beasts that turned into spiritual pets pulled up their front paws at the same time, one black and one red lying on the transparent glass.
, looking at the stones floating in the air one by one, I felt very curious: "What are these?"
At this moment, Baili Wenwen, who was lying on Xi Yuxie's back, was slightly affected by a faint flash of light. Then he raised his head and saw the entire vast galaxy and universe through the window on his side.
His expression trembled slightly, and then he froze there.
Xi Yuxie naturally saw the scene outside, but because he has modern memory, he has seen pictures and videos of the universe. Although he also felt that the picture was beautiful at this time, more attention was paid to Baili Wenrou:
"Is it better?"
"Xi Yuxie, so beautiful!" Baili sat up from Xi Yuxie's body gently but excitedly like a child, looked at him and said, "Look, what is that?"
Immediately, their cabin passed under a huge boulder of unknown object, and the starry sky was blocked by the surface of the moon.
About one in every two Earth-type planets can harbor life, so there are about 650 million planets that can breed life.
Wudandan immediately controlled the cabin and began to descend. In this case, the moon became smaller and smaller, and the whole picture began to fall into sight.
"That bumpy thing is the moon. Look, we flew across the bottom of it." At this time, Wudandan's voice came.
"Blue planet?" Dabao was very excited, as if he had never played this kind of game before and was always in a state of excitement.
"Master, these stones are so big that they can actually float in the air. It's amazing!" Qiongqi's voice came.
Traveling in space must be very memorable.
Wudandan explained, "There are about 300 billion stars in the Milky Way, and the sun is only one of them. It is speculated that there will be only one planet with the required elemental conditions in the ecosystem of every two second-generation stars. In addition,
Earth-type planets with a mass not less than 40% of the Earth's mass are only half of them, so there are about 1.3 billion such planets.
Seeing her appearance, Xi Yuxie also turned sideways and hugged her, changing their positions, and both of them turned to look at the stunning scenery outside the window behind them.
Baili Wenrou explained: "That's why it's called Starry Sky Continent. If you find a blue planet in this vast universe, it means we can go home~"
Because nearly 8% of the planets are too young to harbor life, another 50 million planets need to be reduced, so that the number of planets inhabited by life in the Milky Way is 600 million.
If the evolution of life on these planets is similar to that on Earth, then nearly 70% of the planets, or 416 million, have rich and colorful terrestrial life.
Some of the planetary life forms will also evolve into intelligent creatures and form their own civilization. It is estimated that this ratio is about 1/400, which is about 1 million."
