Harry Potter’s Morning Light

   Chapter 2651 Breakpoint

  The rotation direction of the earth is from west to east, but not all the planets in the solar system rotate in the same direction. For example, the "morning star" Venus, its rotation direction is from east to west.

  If it is extended to the universe, there will be more planets that do not rotate from west to east, and the rotation direction of Uranus is even more peculiar. In short, if you just record the image of the earth revolving around the sun, and play it backwards, it is not surprising, because this is in line with Newton's second law and the law of universal gravitation, which is called time reversal symmetry.

   However, many laws in the macroscopic world do not satisfy the time reversal symmetry. For example, a river flowing from a high place to a low place would look strange if it was "upside down" and the river would flow backwards.

   When you rotate the time converter, you will see what happened during the day "rewinding", instead of "traversing" directly to a certain point in time, and then time continues to flow forward.

Just like a broken teacup has to follow the same path to get back to where it started, you can't go back a few hours, you have to go back a few hours along the river of time, and in the process, Everything you see is upside down.

The position where Hermione turned the time switch was in the ward. Assuming Harry was always in the ward, he would see himself "rejuvenated" upside down, while himself in the chain of the time switch continued to age, but he was still in the ward. Ron Weasley, who was inside, saw Hermione and Harry disappear together, and then pushed the door again from outside the medical wing.

  First of all, Harry and Hermione's "space coordinates have not changed". When they reached the predetermined time, they pushed the door out from the inside of the medical wing, which happened to be "just now" closed by Albus Dumbledore.

  Minerva told Hermione a rule: she must not be seen.

   They did this during Harry and Hermione's time-travel time together, and apart from Buckbeak and Remus the werewolf, only Albus Dumbledore saw the two little ones.

We can understand it this way, from seven o'clock in the evening to the time when Harry Potter uses the time changer, there should be another Harry Potter in "Rewind", he has been going backwards, from the medical wing back to the lake , back from the lake back to the Shrieking Shack, and back from the Shrieking Shack back to the Beating Willow, Ron was dragged into the hole, and they went together to Hagrid's hut, and then back to the Stonehenge sundial, when Harry Potter, who came out of the medical wing, also arrived at that place, and then both Harrys began to move forward in time.

After a series of adventures, Harry and Hermione once again returned to the medical wing. The moment they opened the door, both Harry on the hospital bed and Harry standing in the time-turner disappeared. The "new" Harry can continue to live in this "reversed" world.

   "Two Harrys" are Harrys in the same space and at different times, but these are not the point.

The purpose of   Harry's time travel is to change the "past", and this involves a concept - time reversal symmetry breaking.

In the process of the earth revolving around the sun, the heat released by the sun will also shine on the earth together with the light. Almost as long as there is a thermal phenomenon, the symmetry of time reversal will disappear, and the phenomenon will be irreversible, that is, time unidirectionality.

  When Hermione turned the time converter, the sun that was originally set in the west "rises" again, just like the sun rising from the west, the temperature would decrease after nightfall, and the sun would heat up when it rose.

   If the universe were strictly symmetrical, without spontaneous breaking, then time would not pass and space would not change.

  The most obvious phenomenon in the "lakeside event" was that the temperature became cooler, and this phenomenon continued for several days. The law of conservation of energy is one of the most universal basic laws of nature. It is generally believed that energy will neither be created out of nowhere nor will it disappear out of nowhere, but will only be transferred from one object to another, and from one form to another.

   And the existence of the law of conservation of energy is related to time symmetry.

   Neither Ron nor Harry could leave Hermione's wisdom, but Snape and Feliwick were not the two of them at this time, and their discussion of Pomona was a bit out of sync, and she began to feel bored and distracted.

Whether Harry could summon the Patronus had nothing to do with the ignorance of the Quidditch World Cup, which might lead to chaos, and then Pomona remembered Severus's Apparition-like transfer on the grand staircase, which might be something like Like Death Eater Flying, a spell created by the "Master". With this spell, Severus no longer had to follow the "rules" and was free to move around the transformed stairwell.

   But You-Know-Who doesn't teach for free, Severus has to serve the Dark Lord to get his guidance, he has the Death Eater brand on his arm, and it's said to be more active than the last 13 years.

   But they couldn't do anything, and Scamander tried his best to warn the Minister of Magic to step up his guard, but was ignored.

   "What do you think, Pomona?" Filivie asked.

   She looked at him blankly.

   "Let's talk about it today," Snape said. "We have other tasks to prepare for the Triwizard Tournament project."

   "Okay." Fei Liwei just stood up "By the way, how was your exam yesterday?"

  Severus said nothing.

   "Let's talk about this another day," said Pomona wearily.

   Fei Liwei didn't ask any further questions, and went straight back to the office in the tower.

   She looked at Severus.

   "Don't you feel hot after wearing so much?"

   He was so obedient that he started taking off his coat.

   took off the densely buttoned, dark blue coat, and Snape, who was only wearing a shirt, looked a few years younger, so that she was a little afraid to look at him.

   "It's almost noon, how about we go to the lake for a picnic?" he invited.

   "What happened yesterday?" asked Pomona "Why Fudge..."

   "I didn't know." He interrupted her.

   "That's it?" Pomona asked.

   "That's it." He must answer.

She wouldn't have suspected it if he had stayed "meditation" at the school, but after he disappeared from Smith's house party and was unknown for a few hours until he appeared on the grand staircase, she had to suspect him to go to Mal Fu plotting something.

   "Can you leave him alone?" Severus asked softly.

   "Remus is my friend, I can't…"

   "Down like him," Severus continued.

   "Can't teach at Hogwarts, where will he go?" said Pomona anxiously.

   "At least he doesn't have to worry about the potion." Severus said, "I'll give it to him as promised."

   "I'm going to see it in the afternoon."

   "I understand." He said briskly, "Can we go after lunch?"

  Pomona felt that Severus' behavior was a bit cold-blooded, even if Remus offended him, he should not have such an attitude.

   "Did you stay in bed today?" he asked suddenly.

"what?"

   "It was very late yesterday, and I think you will be tired too," he replied.

   "Then you still want to have a picnic?" she said indifferently.

   "Where else do you want to go?"

   "Whatever!" she said willfully.

   "How about we go to London?"

   She laughed, "Have you forgotten the expression of the clerk who saw you buying clothes last time?"

   "It doesn't have to be Diagon Alley, we can go to the Muggle world, no one knows us." He whispered in her ear.

   But she didn't resist his invitation too much that they could go to the Ministry of Magic after dinner in London.

   But she didn't wear Muggle clothes, even if it was Fengya's wizard robes, it was Halloween for Muggles.

   "Okay?" he asked, grabbing her arm.

   She nodded, and then no one spoke.

   After a while, he let go of his hand and left the music classroom. Pomona breathed a sigh of relief when his back disappeared at the door.

   "Just going out for a potluck with friends." She yelled into the air "This is not a date!"

   But no one answered her, including those ghosts who had nothing to do.

   "What am I thinking." She muttered, and finally left the classroom.

   In the Prisoner of Azkaban film at 1:47:58, you can see two people lying on two beds, Ron in the red sweater on the right and Harry Potter on the left

   From 1:47:56 seconds, you can see blurred figures on Harry and Hermione - themselves, 57 seconds to see Dumbledore walking away, until 48 minutes, there are many figures by the hospital bed...
