In order to explain the famous "grandmother's paradox", Hawking published the "parallel space theory", which was also the first to propose the concept of parallel universes.

In the mid-90s, Stephen Hawking, as one of the greatest scientists, profoundly influenced many teenagers who had just explored the edge of the universe and the edge of time.

Fifteen-year-old Ouyang Lai, after accidentally seeing "A Brief History of Time" translated by Hunan Science and Technology in 1992, was deeply fascinated by the mysterious universe and the time that is missing.

Whenever the night sky was full of stars, she sat on the roof with her legs crossed, closed her eyes, she imagined what a world looked like, and when she opened her eyes, she saw another world again.

She even had some expectations, so she asked her mother, "Will there be the same world in this world but in different dimensional spaces?" ”

Mom served white porridge with dried plum vegetables and pushed it in front of her: "I don't understand you, you go and ask your teacher." ”

Ouyang Lai was a little thin at that time, and the wide red and white school uniform was loosely attached to his body, and the cuffs were empty.

Her stubborn personality is becoming more and more like her divorced father, except that she doesn't deal much with her own father.

She said: "Mom, I recently read a book called "A Brief History of Time", and there is a sentence in it about a lady who is faster than the speed of light, so she left today and arrived the day before yesterday. Can faster-than-light go back in time or into the future? If I could, I would like to go to the future and have a look. ”

Ouyang Lai took the porridge and put it in his mouth little by little with a small spoon.

Mom always smiled charitentially: "I don't understand what you're saying anymore, why is it so rare to have knowledge in textbooks now?" ”

Ouyang Lai shook his head: "I went to the library to read, it's a very interesting book." ”

Mother took the salted duck eggs, peeled them, and put the oily salted egg yolks into Ouyang Lai's bowl: "Oh, extracurricular reading, then you can't miss the time to study." ”

Ou Yalai saw that his mother didn't seem to be interested, so he had to take the handle tastelessly and said, "Mom, this egg yolk is too salty, I don't want to eat it." ”

Only then did my mother raise her eyes, slightly stern: "You don't eat well all day." ”

Ouyang Lai numbled his mouth: "I can eat two bowls of rice when I burn pork ribs." ”

The corner of the mother's eyes froze, and she calculated it in her heart, saying that she would ensure that her daughter would eat a big meal of pork ribs a month, but this month because of the restructuring of the factory, she seemed to have forgotten.

So he smiled as if he was busy making amends: "Ah, mom forgot, mom bought it for you on a cloudy day." ”

"Hiss~~~" As soon as the words fell, my mother covered her stomach and frowned.

Ouyang Lai hurriedly put down the spoon and rushed to her: "What's the matter, Mom?" Stomach ache again? ”

The pain seemed to be very fierce, and it suddenly provoked her to be unable to stand anymore, so she helped Ouyang Lai to lie on the sofa and said reluctantly: "Lailai, give it to Mom, take it, take some painkillers." ”

Ouyang Lai answered, hurriedly went to the bedside table to take the painkillers that his mother bought casually at the pharmacy, and said worriedly: "Mom, you have been in pain like this for nearly half a month, why don't we go to the hospital?" ”

Mom endured the pain and sat up, swallowed the small white pills: "You don't need to go to any hospital, it's just a stomachache." ”

Although Ouyang Lai is only fifteen years old, he always looks a little young and old because of the environment.

She looked firm: "No, you have to go to the hospital today, listen to me, Mom." ”

Mom waved her hand, and because she was thin, she looked a little stiff when she was half-lying on her stomach.

Ouyang Lai looked at his mother distressedly, so he held back his tears, stubbornly walked out of the door, and came to the commissary on the first floor to call 120.

During the half hour of waiting for the ambulance to come, my mother was not relieved by swallowing painkillers, but almost fainted because of the severe pain in her abdominal cavity.

The young Ouyang Lai knocked on the door of the neighbor next door, Grandma Zhan's family, and prayed: "Grandma Zhan, my mother is sick and has to go to the hospital now, but I can't help her, I'm afraid of falling her, can you help us?" ”

Ouyang Lai's eyes were full of tears, and she looked eagerly at Grandma Zhan and Grandpa.

Fortunately, the neighbors are all employees of the same factory, and they are used to helping each other.

So sixty-year-old Grandma Zhan and Grandpa Zhan helped Ouyang Lai's mother downstairs.

It was at this time that the ambulance arrived, and the paramedics carried them on stretchers and took them back to the ambulance.

Before leaving, Grandma Zhan hurriedly went upstairs to take off her cloth bag, took out two hundred yuan and stuffed it into Ouyang Lai's hand: "Grandpa's legs and feet are inconvenient, grandma won't accompany you to the hospital, take these two hundred yuan, if you want to use it, just return it to me when your mother is well." ”

Ouyang Lai nodded steadily with tears in his eyes.

Along the way, Ouyang Lai saw that her mother, who was still alive and well, was actually dying, and she was very scared, she was only fifteen years old, and it was the first time she saw her strong mother curled up in pain, without saying a word.

So she cried and asked the accompanying nurse, "Auntie, what's wrong with my mother?" ”

Seeing that she was still young, the nurse comforted, "It shouldn't be a big deal, what about your father?" ”

With a simple question, Ouyang Lai's teary eyes suddenly became cold.

"I don't have a dad." She said.

The nurse frowned and didn't ask any further.

It took 20 minutes to get to the nearest people's hospital.

Ouyang Lai followed the stretcher in, but was blocked outside the emergency room.

That day, it was March 15th, and it was cold at night, so Ouyang Lai squatted outside the emergency room and shivered.

She suddenly thought of "A Brief History of Time", and if she could, she would like to take her mother to leave the current helpless world at the speed of light.

"You're her daughter?" , I don't know how long it took, suddenly a doctor pushed the door out and stood in front of Ouyang Lai.

Ouyang Lai stood up with the tears that had not fallen, and nodded.

The doctor looked at her, but said, "Where's your father?" Ask him to come to the hospital, and we'll look for him. ”

Ouyang Lai was stunned, but still stubbornly said: "I don't have a father." ”

The doctor frowned: "How can there be no father?" ”

"I just don't." The little Ouyang Lai was expressionless.

The hospital sighed helplessly: "What about your mother's relatives?" Like grandma? Uncle? Aunt? ”

Ouyang Lai lives with his mother, almost dependent on each other, his grandfather has died a long time ago, but there is an uncle who lives in the city, but the uncle doesn't like her and her mother very much, so she doesn't like to trouble him.

So she bit her lower lip and said, "Uncle Doctor, I'm fifteen years old, I've grown up, tell me anything you have to tell me directly, my mother and I don't have too many relatives, and I can't find anyone to help us at such a late hour." ”

The doctor looked at her, sighed silently, and whispered, "Poor thing..."

Then he slowly handed the diagnosis report to Ouyang Lai: "Your mother is very sick and needs surgery immediately. ”

Ouyang Lai looked at the diagnosis report, the black and white color map was printed in the center, and a row of black characters was written underneath: Advanced rectal cancer, ascites compression......
