Volume 4: Spacetime Singularity Chapter 41: Spacetime Singularity (Part 2)
"Is that girl from before really gone?"
"Which girl? The woman of similar age you were with before?"
"Yes, yes, that's her. How is she now?"
"She is no longer in this world..."
"Ah? What do you mean? Can you be more specific?"
"Strictly speaking, the material that makes up her no longer has the organizational pattern necessary for life, so strictly speaking, the person you are talking about no longer exists in the biological and social sense."
Fang Cheng held the bracelet tightly and didn't notice the pain in his finger joints at all.
He could now hear no sound except his own heartbeat, and time seemed to have stopped flowing again.
When he came to his senses, the bed sheet in front of him was already soaked with sweat.
Wait a minute, there seem to be loopholes in what I just said.
"You just said...she no longer exists in this world. What does that mean? Does she still exist in other worlds?"
"I don't know whether it is or not, but there seems to be no word in your language that can describe this situation..."
"Then can she return to this world?"
The alien was silent for a few seconds. Fang Cheng didn't know whether he was hesitating or there was simply a signal delay.
"In fact, the word 'world' has a rather narrow meaning, but there is no other word in your language that comes closer to the meaning than 'world'."
"So what's going on?"
"She tried to travel through time before using a flying machine, but it didn't work."
"What does this mean? Your aircraft has this function? How did she know?"
"I told you before that the outer wall of the surface ring is superfluid."
"Yes, I still remember this..."
The main reason Fang Cheng could remember this was that the concept of "metal superfluid" was too strange. How could metal be a superfluid? In fact, he was puzzled by the concept of metal life from the beginning. Is metal still metal in a higher dimension? How should that new form of matter be defined? And what exactly is metal? Is it metal or what?
"She realized that the surface was designed to be superfluid in order to travel through the wormhole, so she gave that order."
"What does this mean?"
"Your science has proven that if you want to travel through a wormhole, you must be in a container without any friction. This is the same as when we just entered the space age and carried out interstellar travel, so these old spacecraft are all designed with superfluid surfaces."
This point indeed touched upon Fang Cheng's blind spot in knowledge.
"She discovered this at the time, and in order to reverse the situation, she forced the spacecraft into time-space jump mode. But the spacecraft I sent to you is a modified (castrated) version, and that function cannot actually be used."
If half of my brain was on her half of the bracelet at that time, I would definitely have stopped this from happening, but there are no ifs.
"This operation caused her to enter the singularity of space and time and become a point, so this person no longer exists in this world . From the perspective of physics, she is now zero-dimensional."
“…”
"Is there no way to get her back here?"
"The process of extracting information from zero dimensions in reverse requires too complicated technology and operations, and we are currently unable to perform such operations."
In fact, it is because the earth is too remote and there is no equipment nearby that can do such complicated things.
"Then... is there no other way?"
"There is still a way."
Fang Cheng squeezed the bracelet hard, and it slipped out of his hand and flew half a meter away from the bed. He rushed over to pick up the bracelet, and his head hit the side of the bed.
"So what is the specific method?"
"She has disappeared as a matter person, but her antimatter counterpart has not disappeared. We collected all the antiparticles of the elementary particles that made up her body and cut off the entanglement between her and matter before she entered the singularity. So from this perspective, she is actually half dead but not completely dead..."
