A Different Doraemon World

"Even though the technology 500 years from now is highly advanced, it hasn't reached the level of interstellar travel," Karen explained to Doraemon and Nobita. "We still haven't found a planet suitable for human habitation. Not to mention, the distances between planets are immense. Even if we did find a suitable planet, if the distance is too great, it would be meaningless because it's impossible to get there. Spaceships of the future are advanced, but their speed hasn't yet reached the speed of light. Space migration is nothing more than a pipe dream."

Doraemon couldn't help but be stunned. He questioned, "Are you saying that even 500 years from now, humans haven't found a way to overcome the speed of light? Then how did you two manage to discover time tunnels and create a vehicle to travel through them?"

Kelly suddenly butted in, clearly annoyed. "Obviously, it's thanks to the genius of this young lady! And you're asking too many questions for an antique robot like you."

Doraemon observed Kelly's expression. Despite still being agitated, it was clear she was hiding something. It seemed that the creation of the time machine wasn't as straightforward as she had claimed earlier.

"I should press her for more details!" Doraemon thought, but then he shook his head. For now, he decided to set the matter aside and turned to say, "I can help you and the people of the future move to another planet!"

Karen and Kelly were astonished. "You're an early-model robot from 500 years ago. Are you really capable of such a thing?" they asked in disbelief.

This time, Nobita spoke on Doraemon's behalf: "I was just about to tell you earlier—Doraemon isn't a robot I created. He's an alien from the planet Pesi… uh, Peter… no, the Eternal Planet! The technology there far surpasses Earth's, even 500 years in the future."

"An alien? In our time, we've indeed received countless extraterrestrial signals," Karen replied, her tone shifting to one of interest. "We know other species exist out there, but due to technological limitations, we've been unable to decode the messages or establish communication, let alone meet them. Your planet… how far is it from Earth? And how did you come here?" she asked, intrigued.

"Nobita, my planet is called Përjetësia," Doraemon corrected, then turned to Karen. "We come from a neighboring galaxy, about 500,000 light-years away from Earth."

Karen was astonished. "500,000 light-years? Then how did you get here? Even at the speed of light, it would take 500,000 years to reach Earth. Have you found a way to exceed the speed of light?"

Doraemon shook his head. "That's a human concept. According to humans, the shortest path from point A to point B is a straight line. To calculate the distance, you use the time and speed needed to cover that distance. But on my planet, distance is no longer an issue because we've surpassed the limitations of three-dimensional space."

"Oh, can this young lady have an explanation for that?" Kelly asked, her eyes sparkling as she stared at Doraemon.

"For humans, space is constructed in three dimensions: length, width, and height. But for us, having broken through the constraints of three-dimensional space, space is multi-dimensional, and we can manipulate certain dimensions in different ways. To put it simply, we can fold space, bringing points A and B together and bypassing the concept of distance entirely—traveling directly from A to B," Doraemon explained.

Nobita's eyes lit up with understanding. "Is that the principle behind your Anywhere Door?"

Doraemon nodded approvingly. "Exactly. Applying it to spaceships for interstellar travel is a bit more complex, but the fundamental principle is the same: space-folding phenomena. In the universe, there exists a kind of spatial disturbance that folds space. The frequency of these disturbances is random—sometimes 1/1000000000000th of a second, sometimes 1 second. This randomness makes utilizing them very challenging. However, the residual energy from these disturbances can be collected and harnessed. We use that to traverse space and time."

"If that's the case, it explains how you were able to attack us in the time tunnel..." Karen and Kelly nodded. Being scientists, they didn't fully understand but managed to grasp the general idea. After a moment, Karen glanced at Doraemon skeptically and asked, "Do all the people on your planet look like that? You resemble the early-model robots Father created. Could it be that you were his inspiration?"

"Um, um, honestly, your form is incredibly strange," Kelly added, circling Doraemon as she examined him from head to toe. "This young lady simply can't comprehend the anatomy of a being like you—it's so bizarre!"

Doraemon chuckled. "No, our form isn't like this at all. In fact, it's nothing at all..."

"Don't try to mess with this young lady's mind! Nothing at all? This youn—" Kelly exclaimed in shock but was cut off as Karen, without warning, picked up the compression box and smacked her in the face.

"Karen! What the hell are you doing? Why are you hitting this young la—" Kelly's protests were cut short as Karen delivered a few more kicks. Apparently, the presence of her armor meant Karen held nothing back, stomping with full force while gritting her teeth. "This young lady, this young lady—every other word is 'this young lady.' Let me stomp the hyperactivity out of this young lady once and for all!"

Doraemon and Nobita watched the scene unfold in stunned silence. Neither knew what to say. Weren't these two supposed to be the villains a moment ago...?

After some time, Karen turned back and politely said, "Sorry about that. Things are quieter now. Please, continue!" At this point, she smiled gently, appearing every bit like a refined young lady of noble upbringing, while Kelly lay motionless on the ground.
