At that time, she would even wonder if every star in the sky would give birth to a few babies called planets like the sun, and she would even wonder when aliens would come to Earth.

She also likes to watch science fiction movies and has read several science fiction books.

It's just that when she grew up, she thinks about things in life every day, and she doesn't have the mind to think about it anymore.

Mark smiled.

For the uninitiated, such a question is simply too naïve. Of course, he also knew that he was dealing with a woman who knew nothing about astronomy.

"Some stars are born in nebulae." Mark no longer answered He Xiyan in professional language, because he knew that she couldn't understand.

He Xiyan, "It's incredible, I envy your work, I can see the magnificent scenes in the universe every day." ”

Mark:......

Mark just smiled faintly and didn't answer. Of course, he is doing his own research, and although he is tired, he is really happy.

He Xiyan took a deep breath and felt a layer of sweat break out of his back.

Well, at this moment, she admits that Ye Hao did bring her to a place that she found interesting and fun.

"This one?" He Xiyan pointed to another large screen showing a huge disk-like spiral star, no, it should be a galaxy.

"This is the Great Andromeda Galaxy that the WE Space Telescope is observing." Mark replied.

"Andromeda?" He Xiyan was stunned, touched his hair suddenly, and said, "I know this galaxy, she seems to be bigger than the Milky Way."

Mark, "Yes, the Andromeda Galaxy is 220,000 light-years in diameter and 2.54 million light-years from Earth, making it the closest large galaxy to the Milky Way and the largest galaxy in the local group. It is at least twice as massive as our own Milky Way, and according to the latest observations, the Andromeda Galaxy may contain more than 1 trillion stars. ”

He Xiyan felt that his brain was about to run out. Her eyes were fixed on the deep space of the universe under the telescope lens on the screen, so vast, so bright. Countless stars like the sun, countless galaxies like the Milky Way, in the vast universe, the earth where we are located is so small, and we ourselves are even more insignificant, and it seems meaningless for us to fight for these things so small?

He Xiyan suddenly felt that in this journey of life, we got on the train by chance, and when we arrived at the station sooner or later, we could not control the time and place of getting off the train, and only grasped and cherished this good time on the bus in a limited time, and tried to live a full and colorful life, instead of worrying about things that were not worth tangling with every day, and it was not worth living in pain and anxiety every day.

Because time is the most precious thing, it slips silently between us, and after death, we return dust to dust, and finally become the basic matter in the universe.

It's only a few decades, and it's not even a moment compared to the long age of the universe.

He Xiyan instinctively fell into some kind of contemplation, she stood in front of a big screen in a daze, her eyes staring at the vast sky on the screen, she just looked at it, watched it for a long time, and she thought about it for a long time.

They didn't notice that the man next to her had gently placed his hand on her shoulder.

Ye Hao smiled faintly. After getting along for many years, he actually knows her preferences and temperament very well.
