Hogwarts and the Unspeakable

Chapter 63 Grandfather Paradox

When the dragon of time, "Dragonborn", transcends time.

The space instantly turned into nothingness.

Allen watched as the things in front of him disappeared little by little and faded away.

He felt as if he was flying and things were moving little by little.

They were flying upward with the Dragonborn.

However, his body's "kinesthetic" system told him that he seemed to be still where he was.

------

During the flight, did they move in space or not?

Allen, on the Dragonborn's paw, thought this way.

The main reason is that there is nothing he can do.

"Traveling" only happened in a moment, and I didn't even feel anything, and I came to this incredible world.

And Sir Humphrey has been careful over the years not to let him see anything too "magical".

Therefore, in Allen's eyes, everything seems so novel.

Whether it’s a world where “time stops”;

It’s still a world of “turning back time”.

------

However, the Dragonborn still flew with them.

Outside this small space, there is a small galaxy.

Beyond the galaxy, there is endless darkness.

This is true darkness, a darkness without any light at all.

Even the concepts of "darkness" and "light" do not exist.

Complete "nothingness".

----

The dragon's body was too huge, so when she opened her mouth, Allen felt it.

Allen suddenly thought of the TV series "Kobayashi's Dragon Maid" he had watched.

It's a shame, Todd Connor and the others look so cute, gentle and kind, and not too aggressive.

The most important thing is that they are completely devoted to the protagonist "Xiao Lin".

Allen didn't look so lucky. However, it is not "that" unfortunate.

Compared to another "Alan".

----

The Dragonborn's words interrupted Allen's thinking.

"I interrupted you just now because the situation is urgent."

The Dragonborn's voice was as hard as a rock.

Well, there is no voice to make them "cute" (at least when they turn into dragons).

"Have you ever heard of the 'grandfather paradox'?"

asked the Dragonborn.

"That's why we don't go to 1880, but to 1984."

------

The Dragonborn spoke in a deep and distant tone: (There are too many quotation marks here, so I will omit them)

People can travel through time, and timelines can interfere with each other.

So, what would happen if a person traveled back in time and killed his grandfather?

----

If a person travels back in time, kills his grandfather, and kills his grandparents before his father is born. If his grandfather is killed, his father will not be born. If his father is not born, then the murderer himself will not be born. So, who killed "grandfather"?

If we want to travel back in time and kill our grandfather. So assuming this situation really succeeds, based on the previous situation, we ourselves cannot exist.

So, the fact that we can exist shows one thing:

We cannot kill our own grandfathers.

It can further be explained:

Time travel cannot exist because there is a problem with the law of cause and effect.

----

Dragonborn, said so.

Later, Snape made some academic additions:

----

The grandfather paradox is a time travel paradox and a common theme in science fiction.

This paradox was first proposed by French science fiction novelist René Barjavel in his 1943 novel "Le Voyageur Imprudent" (Le Voyageur Imprudent).

----

Allen also nodded.

In fact, of course he has heard of and understood the grandfather paradox. However, sometimes, isn't it better to give others a chance to perform?

"So, if time travel isn't possible, what are we doing?"

So, Alan Appleby asked.

Here's the Dragonborn's explanation:

----

Actually, this question is very simple.

Because I myself was blessed by Akatash and gained the ability to travel through time.

When I traveled back in time, in fact, at that moment, the timeline had already been broken.

When any "time traveler" travels through time.

The world is essentially in a state of "everything is still", at the intersection of countless possibilities.

You humans always think that time flows infinitely, but in fact, this is not the case in my experience. Time will stop. It may become broken points, or it may be stitched together.

In fact, this idea is also very simple:

Human beings have no access to a world where "time stops".

In other words, when "time stops", you can neither see nor hear.

During this time, no movement, including thought, takes place except for my own. Therefore, if you cannot even observe it, even the "entire knowable world" that you can access changes at the same time. Even if time could stop, would you really be able to feel it?

It's completely impossible to feel it.

----

At this time, Allen's eyes widened, and together with Snape, he listened to the Dragonborn's "teachings".

----

I am activating it within my "field". If you do this outside, you will find that the world actually stops.

In fact, the world stops.

(Dragonborn, emphasized)

It's as if the world is in motion, and that's all you know.

In my eyes, the world is divided into scenes.

Therefore, when I "traveled" through time, at that moment, everything in the world we were in stopped.

Everything will wait until we change the time and return here before new results will appear.

So, in fact, the grandfather paradox works like this:

----

When I went back in time, the world was divided into the "new world" and the "old world." When I returned to the old world, the new world was stagnant. When I change things in the "old world", the "new world" is completely unaffected. They are, in fact, completely disconnected, cut "slices".

The moment I changed everything and returned to this world.

All the consequences will unfold in an instant!

----

So if I traveled back in time and killed my grandfather.

Then in that moment, I won't be affected in any way.

As long as I stay in the "past" forever, I'll be fine.

However, when I return to the "present world", the cause of my grandfather's death will be transmitted to me.

I would be obliterated in that moment.

This is the truth of time!

----

Just like that, the Dragonborn finished speaking.

Allen's eyes widened when he heard this. So, is this the world in the eyes of the Dragonborn?
