Parallel Universe
In a small town, there was a very smart man named Christopher. He was a physicist, which means he studied how tiny things like atoms and energy worked. Christopher loved to read books, write notes, and do big experiments in his lab. He spent hours every day working with strange machines, blinking lights, and wires that buzzed.
One evening, Christopher jumped out of his chair.
"I did it!" he shouted.
He looked at the screen on his computer and smiled. He had found a way to change how tiny particles behaved. These particles were smaller than dust—so small that no one could see them. But Christopher had found a way to move them to different places and even change their shape.
He picked up his phone and called his best friend, Emily. She was also a scientist and worked in a different lab.
"Emily, you need to come to the lab now!" he said.
"Why? What happened?" Emily asked.
"I discovered something big. Really big!"
A few minutes later, Emily arrived at the lab. Her eyes were wide.
"Tell me," she said. "What did you find?"
Christopher smiled. "I found a way to move particles. Not just move them—but send them to other states. I think... I think we can reach other worlds."
Emily frowned. "Christopher, that sounds very risky."
"But exciting too, right?" he said.
She crossed her arms. "Maybe. But you must be careful. One small mistake could cause something really bad."
"I’ll be careful," he said. "I promise."
That night, Christopher could not sleep. His mind kept spinning with ideas. What if he really had found a way to visit a new world? What would it look like? Would there be people? Would the air be safe to breathe?
The next morning, Christopher went back to the lab. He set up a big machine in the center of the room. Wires were everywhere. The machine made soft humming sounds, like it was alive.
He looked at the button. Just one push.
"Here we go," he whispered, and pressed the button.
Suddenly, the room filled with light. Bright blue and green colors flashed around him. A strange wind blew through the lab, even though the windows were closed. Then, right in front of him, a round glowing door appeared. It floated in the air.
Christopher stared. "Is that... a door to another world?"
He stepped closer. On the other side, he saw trees, mountains, and a river. It looked like Earth, but the sky was purple, and the trees had silver leaves. The animals walking near the water looked soft and shiny, like made from glass.
Without thinking, he stepped through the door.
The new world was quiet. A cool breeze touched his face. Birds flew above him, but they had four wings instead of two. The ground was soft, like a sponge. It was beautiful.
But soon, things got strange.
The sky turned yellow. Then green. The ground under his feet started to shake. A rock nearby disappeared into thin air. A flower grew fast and then turned into dust.
Christopher’s heart began to race.
"What’s happening?" he said aloud.
Then he felt it—his body started to feel heavy, like something was pulling him apart. He looked up and saw cracks in the sky, like broken glass.
"This world is not stable," he said. "It’s falling apart!"
He ran back through the glowing door and landed hard in his lab.
Emily was already there, looking scared.
"Christopher! Are you okay?"
"No!" he gasped. "The worlds are breaking! I think I opened something I shouldn’t have."
They looked at the machine. It was sparking. Smoke came from one corner. The screen was flashing numbers quickly.
Emily grabbed a wrench. "We need to fix this. Now!"
Christopher nodded. "If we don’t, both worlds might crash into each other. Everything could be destroyed!"
Together, they worked fast. Emily handed him tools, and Christopher adjusted wires. Outside the lab window, the sky began to turn red. Strange shadows moved across the streets. Some had glowing eyes and long arms. They were not from Earth.
"What are those?" Emily asked.
"Creatures from the other world," Christopher said. "They’re slipping into our world."
The machine beeped loudly. The screen blinked. Sparks flew.
"We don’t have much time," he said.
Suddenly, one of the creatures appeared in the lab. It had long arms and no face. Its body looked like smoke.
Emily froze. "What do we do?"
Christopher picked up a metal pole. "Keep it back while I finish the machine!"
Emily stood in front of the creature, waving the pole. "Go away!" she shouted.
The creature paused, then slowly backed away. Its body melted into the floor.
Christopher yelled, "I got it!"
He pressed the button again. The glowing door started to close. The light faded, and the machine stopped shaking. The creatures began to vanish, one by one. The sky outside turned back to blue.
It was quiet again.
Emily dropped the pole and sat on the floor. "That was too close."
Christopher sat beside her. "I know. I should’ve listened to you."
Emily looked at him. "You’re a great scientist, Christopher. But you must remember—just because we can do something doesn’t mean we should."
He nodded. "You’re right. I was too excited. I didn’t think about the danger."
She smiled a little. "Next time, let’s test things slowly."
"Agreed," he said.
The two friends sat in silence for a while. Then Christopher stood up.
"I’m going to fix the lab and lock this machine away," he said. "It’s too powerful."
Emily nodded. "Good idea."
From that day on, Christopher changed. He still loved science and learning, but he was more careful. He always tested things slowly and talked to Emily before trying something big.
He never forgot the day he saw another world. He also never forgot the danger. He knew that science was powerful, but it needed to be used with care.
He also started writing about what happened. He wanted other scientists to learn from his mistake.
One day, while cleaning the lab, Emily said, "Do you think we’ll ever go back to that world?"
Christopher shook his head. "Not unless we know it’s safe."
She smiled. "Good answer."
He smiled back. "And if I ever forget, you’ll remind me."
"Always," she said.
And so, Christopher and Emily kept working together. They made many great discoveries—but only after making sure they were safe. And Christopher never again opened doors he couldn’t close.
