Chapters (20)
“Very good. You can understand a little. It makes you seem like a physics student, albeit still a superficial one. Yes, we will see all the stars in the universe blueshift at the same time, not one at a time from four years to fourteen billion years from now. This is due to quantum effects over a cosmic scale. Its mathematical model is extremely complex. It’s the most difficult idea in physics and cosmology to explain. I have no hope of making you understand it. From this, though, you’ve already received the first revelation. It warns you that the effects produced from the universe contracting will be more complex than what people imagine. Do you still have questions? Oh, you don’t have to go right away. What you have to take care of is not as urgent as you think.”
“Compared to your entire universe, the flooding of the Yangtze River is obviously not worth mentioning. But while the mysterious universe admittedly has its appeal, the real world still takes priority. I have other questions, but I really must go. Thank you, Professor Ding, for the physics lesson. I hope everyone sees what they want to see tonight.”
“You don’t understand what I mean,” Ding Yi says. “There must be many workers battling the flood right now.”
“I have my responsibilities, Professor Ding. I must go.”
“You still don’t understand what I mean. I’m saying those workers must be extremely tired. You can let them go.”
Everyone is dumbstruck.
“What … let them go? To do what? Watch the universe contract?”
“If they aren’t interested, they can go home and sleep.”
“Professor Ding, surely you’re joking!”
“I’m serious. There’s no point to what they’re doing.”
“Why?”
“Because of the contraction.”
After a long silence, the governor points at the ancient star atlas plate displayed in the corner of the auditorium: “Professor Ding, the universe has been expanding all along, but from ancient times until today, the universe that we can see hasn’t changed much. Contracting is the same. The extent of humanity in space-time, compared to that of the universe, is negligible. Besides the importance to pure theory, I don’t believe the contraction will have any effect on human life. In fact, after one hundred million years, we still won’t observe even a tiny shift caused by contraction, assuming we’re still around.”
“One and a half billion years,” Ding Yi says. “Even with our most accurate instruments, it will be one and a half billion years before we can observe the shift. By then, the sun will already have gone out. We probably won’t be around.”
