Tomorrow's Ark is too real

Chapter 173 Absolute Existence
Time and space, this is a collective noun, that is, time and space.

The connotation of time is endless and eternal, and the connotation of space is unbounded and eternal. "Endless" and "boundless" are the absolute concepts of time and space.

"En~en~en~en `shuttle through time and space~."

From the literal point of view of this lyric, traveling through time and space is obviously a contradictory sentence. The sky, the deep sea, and isolated islands can all be shuttled, but how to travel through time and space?
In other words, if a race has the ability to travel through time and space, it will completely subvert the existing theories of this world, because this involves an unavoidable problem, the time paradox.

Time paradox, this is caused by time travel or traveling through time and space. The logical deduction is contradictory. To put it simply, the same person in the same space cannot appear on the same current timeline, no matter what time point they come from. cannot appear.

Because, according to the evolution of the Butterfly Effect, once a person’s past or future behavior deviates, the chain reaction will be unpredictable. If it really happens, it will even be so serious that the world will disappear due to the collapse of logic in theory. .

However, unless there is a situation.

That is the person who travels through time. He has no impact on this world from the beginning to the end. His birth, growth, and final disappearance cannot affect the current trajectory of the world. To the world, he is people who don't exist.

Of course, this kind of situation is very difficult to happen. It is impossible to have no impact on the world at all. As long as you eat and breathe, it will hardly cause a small amount of impact. What about the conditions?

Since it is impossible to have no influence at all, then reduce the influence to a minimum.So, how can we achieve the least impact?
If a person or race does not exist in the eyes of creatures all over the world, something that has never been heard of, even if someone has heard of it, but has not really seen it, then it has the least influence.

Combining the above analysis, there is only one group that fits, the deep sea group.

Looking at Skadi's bewildered expression, Xia Feng felt that she herself did not know the information about time travel, that is to say, there was a great possibility that this phenomenon happened without her knowledge.

Taking another [-] steps back, Xia Feng can't be sure whether the past event she just mentioned is time travel.

If you analyze it from an absolutely objective point of view, this is no longer a question of science or magic, but a philosophical question.

For example, a primary school student picked up a wounded animal, and he brought the animal to the class. In order to cultivate the love of the students, the head teacher asked the class leader to use the class fee to buy food for the animal. Then the question arises, what is the animal? What is it? From the first time they saw it, the whole class thought this animal was a cat. As a matter of course, the class leader went to buy cat food.

But in fact, this animal is not a cat, but a tortoise, isn't it surprising?It is a tortoise. You can think that all the students in this class have their heads kicked by donkeys, but they are stubborn and think that this little tortoise is a cat. Then, in a certain sense in this time and space, this tortoise is a A cat, because of its existence, led to the sale of a package of cat food, and through the dissemination of the students, the information of picking up a cat may have other effects.

This is an alternative manifestation of idealism. A person who travels back from the future through a time machine stands on the road, but all passers-by think he is mentally ill, so he is mentally ill, unless his Behavior can cause qualitative change, otherwise the impact he can cause is only the impact of a mental illness.

That is to say, if Xia Feng thinks that the past event mentioned by Skadi is related to time travel, or thinks that it is just a dream of hers, there will be a deviation in the result, but this deviation is in the future, and he has no way of knowing it now.

think carefully.

If Skadi has experienced time travel that she doesn't even know about, that's also true.
kindness?
Thinking of this, Xia Feng suddenly realized a problem, as if he suddenly found a hidden third road at a fork in the road from left to right, which gave him a flash of inspiration.

On the deck, Xia Feng frowned and began to think seriously.

In his cognition, the changes of all things are relative, that is, they need reference.

For example, in a 20-meter race, if you fall down as soon as you reach [-] meters, then you are behind. If everyone falls down at this time, then you are not behind, it just remains the same. However, if other people not only Falling down, and going backwards in a weird way, then in a sense, you're on the ground, but you're moving forward.

If the time and space of the whole world are changed, no matter whether it is backward or forward, all things have changed according to the order of evolution, but you have not changed.

So is this a kind of time travel?
No matter when, the boundless ocean looks the same, even the creatures living in the sea can hardly notice the change. To put it bluntly, if the time in this world goes back three years now, the scenery he saw on the boat would be the same. No changes will occur.

The difference is that he might meet someone who existed in this time and space three years ago.

Just like the past that Skadi mentioned.

Looking at Skadi's confused look, Xia Feng made a bold guess in his heart.

The so-called traveling through time and space of the deep sea family is not really traveling, but not affected by changes in time and space. This range may be the whole family, or specific people in the group, such as blood and so on.

Of course, even if the facts are as he guessed, he still doesn't feel clear, because there is another question that he can't figure out the answer to, who is the person that Skadi met back then?
To be honest, Xia Feng already had a terrifying guess in his heart, but even he himself couldn't believe it, or he didn't want to believe it.

The sunset in the sky is getting redder and redder, and it looks like tomorrow will be a fine day.

Skadi at the edge of the deck flicked her hair.

"Why are you silent all of a sudden?"

Xia Feng immediately recovered from his thoughts.

"Oh, nothing, just remembered something, you can continue talking."

"I have nothing to say. If you have no other questions, we may have to say goodbye. Although I am very interested in the braised fish you mentioned just now, I am afraid I have no chance. I still have important things to do. "

After all, Skadi stood up and easily raised the strange giant sword next to him with one hand.

Seeing what she wanted to say, Xia Feng immediately spoke.

"Wait a minute, I have one last question."
