Chapter 90： time paradox

In the famous grandmother paradox, it is said:

Suppose you go back in time and kill your grandparents before your father was born, but this action creates a paradox: you go back in time and kill your young grandmother. There won't be you, so who killed the grandmother?

Or think of it as: Your existence means that your grandmother did not die because of you, so why did you kill your grandmother?

Tywin almost had this problem using the time switch. He was attacked by himself without knowing it, and was seriously injured.

Tywin, who traveled back, obviously didn't understand the complicated relationship here. He only saw himself coming towards him, thinking that it was the attacker, so he took the lead in raising his wand.

However, that was actually the beginning of me.

If Tywin was still alive, he would probably have looked up to the sky and asked, "Who killed me, and who did I kill?"

William sat on the chair in the office and continued to analyze the whole incident.

"After Tywin attacked 'self', there was nothing to stop him, he went to the Ravenclaw lounge to kill Robert and took the knocker.

At this time, he had already fought with 'self' three times, and suffered serious injuries.

He drank the compound decoction he had prepared for a long time, changed into Professor Snape's appearance, and went to the medicine storeroom. "

"Why does he want to look like Snape?" asked one of the principals in the frame.

William recognized it as Armando Dippet, the headmaster of the previous term.

"It's very simple, Tywin fought 'Snape' in the corridor on the fifth floor, he didn't know it wasn't Snape, but it didn't prevent him from thinking so.

Since there was a fight, Snape would definitely go to the headmaster's office to find Professor Dumbledore, and there was no one in the medicine storage room.

So, he drank the compound decoction he had prepared for a long time and turned into Snape's appearance. He wanted to get some healing potion, and then took advantage of this appearance to escape from the school with the door knocker.

But he didn't expect that Professor Snape was in the medicine storage room, and the two fought. "

This is also the earliest memory William saw in Dumbledore.

Snape recalled that a man exactly like him tried to break into the medicine store, and the two fought.

It's just that Tywin was seriously injured, not Snape's opponent. He didn't expect to be hit in the chest by black magic, and then escaped again, while Snape rushed to Ravenclaw to check and found Robert's death.

"At this time, Tywin used the time converter for the third time, trying to stop the first self from getting the ring.

But he never expected that he, who had just left the Defense Against the Dark Arts office, would be regarded as Professor Snape. "

William stirred the Pensieve, revealing the fifth floor corridor where Tywin and Snape were fighting.

"This is the fifth time Tywin has been injured. He found himself trapped in a time loop, so he wanted to hide in the Room of Requirement, but Lu Wei was hiding there."

"The whole process of the professor is like this. What's wrong with what I said?"

Dumbledore applauded, not only him, but also the headmasters in the frame.

The only one who didn't applaud was Phineas Black, who snorted and called Tywin a fool.

"William, you're better than I thought. I thought you couldn't find the connection in the end, and you will come to me again. You are indeed a Ravenclaw." Dumbledore praised.

"No, I've been thinking about it for a long time. If it were you, you would have found the problem at a glance." William said modestly.

"You flatter me too much, I'm not omnipotent, many people have wisdom that I don't have.

Fortunately, there are no outsiders here. After Professor McGonagall praised me for being noble, I have never blushed like this. "

"Then Professor, I have a question."

"what?"

"Since Tywin already has a time-turner, why is he looking for a Ravenclaw ring for an ethereal legend?

Using the time converter directly, wouldn't it be possible to travel back in time? "

Dumbledore shook his head, "Do you really think so?"

"Isn't it?"

"I think you read a sentence repeatedly when you learned about the time converter?"

"No abuse!"

"That's right." Dumbledore crossed his hands and leaned back on the chair.

"According to the results of the current study, the longest look-back time that does not have a serious impact on the traveler or the time itself is about five hours, and the number of uses per time period cannot exceed two times.

All attempts to go back more than a few hours have had disastrous effects on the witches and wizards involved.

For many years, it was unclear why time travelers couldn't survive trips that spanned too much time.

But these experiments were terminated in 1899, when Eloise Mintab was trapped in 1402 for five days.

On the way back, her body had aged five centuries and suffered irreparable trauma. Not long after she was rescued, she died at St. Mungo's Hospital for Magical Injuries and Sickness.

Likewise, the five days she spent in the distant past severely interfered with the life trajectories of everyone she met, and their lives were significantly affected, causing their present-day at least twenty-five descendants to disappear~ www.novelhall.com ~ never born. "

"Finally, there were signs of danger, and in the days following Mrs. Mintab's return, time itself was disturbed as the rules of time were severely broken.

On the Tuesday after she resurfaced, the shift lasted two days, and on Thursday it became a four-hour shift.

The Ministry of Magic has been in trouble to cover this up, and has since spawned the strictest legal regulations and penalties around time travel research. "

"Even under the management of the Ministry of Magic, the use of an extremely limited number of time converters is subject to hundreds of laws."

"While it's nowhere near as dangerous as traveling through five centuries, going back five hours can still have serious consequences.

As Saul Crocker said, 'The human mind cannot understand time, and therefore cannot understand the damage that can be caused by trying to break the rules of time. ’”

After listening to Dumbledore's words, William nodded.

Even if Tywin didn't go back to five hours ago, only in forty minutes, and he only used the time-turner three times, it almost caused him the serious effect of killing himself.

If he uses the time converter and goes back ten years ago, more unpredictable things will happen, which is why he is looking for the Ravenclaw ring!

After all, according to rumors, the Ravenclaw ring has no side effects during time travel.

William suddenly thought of one thing. Tywin used the time-turner many times, and the reason in the beginning was because Dumbledore went to the Ravenclaw lounge without warning.

This triggered a series of avalanche accidents after Tywin!

It's terrifying to think about!
