Manual of Space-Time Interference

The things in my head are still those things, should it be tofu dregs or bean curd dregs, and I haven't learned anything profound in dialect during this period of time in Xingshi Base.

After all, on Teacher's Day last year, he felt that he had given back the knowledge he had learned as a gift...

But this is what I say, but really speaking, Dialect feels that everything he has done during this period is still very fulfilling, and his thinking has begun to be gradually opened during this period of time, not limited to this one. Earth is not limited to China.

Many people think that 13.7 billion light-years is the universe we can observe now, because the universe was only 13.7 billion years old, but in fact it is not the case.

The limited history of the universe, coupled with the limited speed of light, inevitably leads to a limited observable universe, but the farthest universe we can observe is not simply multiplying the speed of light by the age of the universe, because it also needs to be multiplied by a scale factor.

In cosmology, we call the distance after eliminating the influence of space expansion "coordinate distance", and the distance seen in the universe is called the co-moving distance, so as the name implies, the co-moving distance is the distance where the universe expands together.

The proportional conversion factor between them is called the "scale factor", which is the a(t) in the RW degree normalization. In the universe dominated by matter, the scale factor is proportional to 2/3 of time. If the Hubble Multiplying the distance by this scale factor and integrating it over time gives a distance of about 46 billion light-years, or the event horizon where we can now see the universe.

It's very big. In comparison, the earth is just a speck of dust. Perhaps to be precise, it's more like an atom, and even quarks are extremely small...

So when Dialect looked at the night sky again, what he could see, or what he could imagine, was very different from before. It was as if he was looking at the night sky now, but his heart was full of complaints.

Isn't it good that the weather is sunny and the visibility is high. What does this dark area mean, the stars and the moon are blocked...

Dialect thought, then lowered his head again, and walked honestly to the place where he should go, where he has to go once a month and spend 3 hours each time.

"Dialect, early!"

"Dialect, how do you feel?"

The people next to him sent greetings from time to time, and the dialect kept waving in response, but there was not much smile on his face, just like the clouds in the sky covering the stars, and his heart seemed to be faintly suppressed by something.

Could it be that my crossing will have a catastrophe this time?

Fang Yan thought about it, and then moved his fingers silently, but did not come up with any results. He looked at the serious and tense things around him, and slowly exhaled, continuously inhaling, exhaling, and finally I vomited out some of the troubles in my heart.

"Dialect, come drink some water and eat something."

Yan Hongchang sat at a table and shouted, and then untied the cover that was still covering it. After a burst of steam, the fragrance slowly came over, but the dialect still had no appetite.

"What's wrong? Unhappy?" Yan Hongchang asked, looking at the silent dialect.

"I don't know what the situation is, but it's okay, I just can't bring up my interest. It is estimated that it is the low ebb of emotions." Dialect said, exhaled again, and then looked at the white fog under the strong light, slowly Slowly picked up the chopsticks.

"The right eyelid didn't jump, didn't your right eyelid jump quite a lot when you were at Atlantis?" Yan Hongchang asked softly.

"No, there shouldn't be any major situation." Dialect said, looking at the rich breakfast at 3:30 in the morning, he took some light things, and then ate it directly with the gruel.

"Be careful, come back and we'll give you a year-end bonus, and then go home happily for the New Year." Yan Hongchang said, trying to arouse the mood of the dialect.

"Yeah!" Dialect replied in a low voice, then nodded lightly, stared at the bright light not far away silently, and then turned to look at the piece above, which was shrouded in clouds. The night sky, finally took the initiative to say, "Old Yan, I think it's a little overhanging this time."

"How to say, what are your thoughts?" Yan Hongchang asked.

"Look, there are dark clouds, according to metaphysics, something big must happen!" Fang Yan nodded, looking at Yan Hongchang and continued, "Isn't it written in that document, the Three Wars is the next easiest for me to cross In the future scene, I think this time it is estimated that it will almost reach the center of the frontline battlefield."

"Isn't there still ancient times? Besides, you think it's so easy in the center of the battlefield, and the earth is so big." Yan Hongchang waved his hand and objected.

"I'm not sure what Ice Age, Triassic, when life on earth began to sprout, but according to the previous rules, I have the greatest possibility to travel to ancient times this time." Dialect continued.

"Be cheerful, relax your mind, the earth is so big and the universe is so big, you are not allowed to teach aliens to speak Mandarin, right? The entire universe will speak Mandarin by then." Yan Hongchang laughed.

"This is reasonable, maybe it's really possible in the future." Fang Yan also had a smile on his face, then looked at the countdown next to him, and said, "It's almost time, I should go too, remember to prepare for the New Year. A big red envelope!"

"No problem!" Yan Hongchang replied affirmatively, then raised his hand, the same gesture he would make every time he crossed, and slowly raised his thumb towards the dialect...

"3!" "2!" "1!" "0!"

The countdown on the electronic clock was cleared in an instant, and then returned to 31 days at 0:00, continuing to count down to the bottom, and the dialect also disappeared in an instant, and went to that unknown time and space again...

...

"Abnormal environmental monitoring~www.readwn.com~ abnormal gravity, abnormal air, the five o'clock program is the 0th program sequence!"

"The satellite cannot be connected, the communication cannot be connected!"

"Currently in location, searching..."

"no need……"

In a word, Nuwa's alarm sounded softly, Nuwa's voice paused, and then slowly stopped, but in the background, there were still non-stop attempts...

Dialect tried to move his hand, and then tried to move his leg a little, with a faint smile on his face, and then slowly stopped.

"There isn't any solution, right?" Fang Yan asked softly, but got no response. He smiled, then took a long breath, and after taking a deep look at the scene in front of him, he felt comfortable smiled and slowly closed his eyes.

When you are outside the earth, please take a look at the earth next to you...
