After understanding the cause and effect, Molly held her delicate and smooth chin, her thin willow eyebrows were tightly locked, and she quickly entered the state and began to analyze for Irin.

"First of all, I have to make one thing clear, one thing about the truth of the theory of time travel."

Molly pointed to several patterns in the three-dimensional holographic projection.

"There are many theories about the shape of time."

"These are probably the ones that are more famous."

"First of all, there is a saying that the time we are in is actually a closed circle, whether it is the past, present, or future, it is just a point on the circle, and this ring cannot be destroyed or interfered with, so time and space travel is theoretically impossible to stand."

"Hmm...... The most famous argument about this argument is the space-time paradox, assuming that A travels back in time and kills A's grandfather, theoretically there will be no birth of A, and there will be no birth of A's grandfather and no death of A's grandfather...... Wait, I'm so easy to understand, with your IQ, you should be able to understand it, right? ”

Halfway through speaking, Molly glanced at Irin suspiciously.

Yi Rin didn't get angry, but said that this kind of scene where he didn't have to use his own brain really made Yi Rin nostalgic.

He smiled and nodded, "Go on." ”

Think about it carefully, when did you start to think before you act, and develop a good habit of planning before acting?

If memory serves......

It must have started after Molly's death.

Molly took another sip of coffee, moistened her throat, and continued: "There is also a theory that time is made up of discontinuous 'points', and theoretically, anyone can move at each point of time if the conditions are sufficient......"

"There are many more points like that. I can't finish talking for a while, and then the point is to cheer up. ”

Molly saw that Irin's expression gradually became confused, so she knocked on the table, revealing an expression of hatred for iron and steel: "I personally support the parallel timeline theory. ”

"First of all, let me ask you a question."

Molly stared at Irin's eyes, a glimmer of indescribable excitement in those bright eyes.

"Since you killed Xiao Yang, who will be an elite monster in the future, has there been any change in your memory of the future?"

"Memories of the future?" Irin was puzzled.

"As such a pivotal figure in the future, according to the butterfly effect theory, there will definitely be major changes in the future, so you have experienced two kinds of time and space, do you have two different versions of memory? Like what...... Someone who is dead, but still alive in another version of memory? ”

"There are no two kinds of memories." Irin looked at Molly's face and said slowly.

"I see...... Molly tilted her head in thought, then wiped her hand a few times on the holographic 3D image.

Erase all other messy graphics.

Only a simple pattern remains.

A bifurcated line.

Molly looked at the simple patterns on the holographic 3D image.

He was full of emotion: "I didn't expect that the problem that has plagued countless scientists for hundreds of years can be solved so easily......"

Irin's stunned: "What do you mean?" ”

"The model of time, the theory of time and space-time, I don't know how many scientists have put forward hypotheses and debated endlessly over the past few hundred years, but do you know why, after hundreds of years of quarrelling, there has been no result?"

Molly smiled slightly, and there was an intellectual light all over her body.

Irin shook her head.

"Hehe, because, there is no 'observer' like you. Take this model as an example, this line is the time we are in now, I call it Line A, and the other line is the time and space that you have come to an end before, I call it Line B, and these two lines are not interfering with each other and do not intersect each other......"

"Once there is a major historical event, line A may form two completely different time and space, line C and line, and line B may also divide line E and line F......"

"And you, it's equivalent to moving from this position on the B line to here......"

Molly gushes and then uses a short line to connect the A line with the B line.

"You should understand by now, right?"

Molly's mouth was so dry that she couldn't help but drink her coffee.

Yi Rin's expression was very serious, very serious, he looked at the graphic in the void that recorded the mysteries of this time and space, and after about a minute, his eyes flashed, and he said slowly, "I don't understand. ”

"Refill."

Molly's expression darkened, and she slammed the empty cup directly into Irin's face.

“……”

……

Time travel small class restarts.

"In words you can understand, when you are reborn from Line B to Line A, it's not the timeline itself that changes, it's the ...... You as an 'observer'! ”

"In fact, many people have long noticed that in history, there are major historical events that are enough to change human civilization."

"Don't mention the ancient times, take modern times as an example, Emperor Chongzhen of the Ming Dynasty inexplicably killed Li Zicheng with one punch, pushing the originally crumbling Ming Dynasty back to a new peak......"

"Thirty-two years ago, scientist Widge Douglas successfully made a small 'wormhole' model, confirming the feasibility of 'space transition technology'...... Of course, that model only existed in the world for about ten seconds before a horrific explosion occurred...... Leave this at that. ”

"November 11, 2111, four ...... The appearance of the tower and the existence of the forbidden space zone have set back the scientific and technological civilization of mankind by several decades, and also destroyed the illusion of mankind entering the interstellar age. ”

"Someone once raised doubts, if Emperor Chongzhen of the Ming Dynasty did not kill Li Zicheng with one punch...... If those four towers hadn't appeared, what would the world be like today? ”

"But there is no 'observer' there, and no one can confirm the change in the timeline."

"Therefore, all the theories of time and space travel are just unsolvable theories, because no one can confirm them."

"And your appearance can confirm that the time model is indeed branched linear, not closed circles, nor discontinuous points......"

Irin listened quietly.

Finally, Molly stopped.

Irin's eyes flickered, and he seemed to understand something.

However, he only wanted to know the answer from Molly.

"So what?"

"So?" Molly spread her palms: "So Miss Ben is sorry to tell you that your rebirth can't change the fact of the end of the world in Timeline B, for you, everything that happened in that timeline has become your 'past'!" The only thing you can change is the timeline you are currently in, the future that has not yet had time to happen! ”

"It's okay...... the corners of Irin's mouth showed a hint of bitterness: "For those who have that kind of memory, it's enough to have me...... At the very least, in this world, I'm still alive, everyone...... All are alive. ”

Molly's lips moved, and she was about to say something.

For some reason, Irin's lonely expression made her chest feel tight.

Right now.

Irin's face changed slightly, and he raised his index finger and made a silent gesture to Molly.

"Shhhh

Outside the door, there was a sudden and almost imperceptible movement.

……

PS: Molly: What about your referral votes? Believe it or not, Miss Ben stomped you to death?
