Ever since people had wisdom and rational thinking, there have been people who have doubted the reality of the world.

Who am I?

Where am I from?

Where am I going?

Thinking about these three questions constitutes something called philosophy.

And among the countless philosophers and thinkers who have emerged since ancient times, there is a great existence that has developed skepticism to the extreme.

Cartesian ......

"Everything that I thought was the closest to the 'real' so far came from feeling and the communication of feeling. However, I have found that these things often deceive us. Therefore, the only wise thing is to stop trusting what the eyes see. ”

If the outside world helps us to perceive things that cannot be trusted, what about our active perceptual activities and thoughts?

These activities are also often seen in dreams, making it impossible to distinguish between "dreaming" and "waking up". Therefore, I have to wonder if the whole world is just a dream.

Zhuang Zhou dreams of butterflies, or butterfly dreams of Zhuang Zhou?

Proceeding from these simple, preliminary "doubts," Descartes pushed his suspicions to the extreme: "I am willing to assume that the source of all truth is not a merciful God, but an equally cunning, equally powerful demon, who wields all his might to lead me astray." I would like to assume that the sky, the air, the earth, the shapes, the colours, the sounds, and all the external things are but the manifestations of the deceitful dreams which the demon wants to use in exchange for my credulity. I look at myself as if I have neither hands nor eyes. There is no flesh, nor blood, nor any organs. It's just a foolish belief in the existence of these. ”

The well-known "brain in a vat" hypothesis is a demonstration of this suspicion.

Then faced with the fear that all of this was false, Descartes, as the discoverer of this fact, came to a conclusion that made him happy.

"I think, therefore I am."

When I doubt the existence of everything, I cannot deny my own existence, because when I deny and doubt, I already exist!

Because I'm thinking when I'm skeptical. There must be a "thinker" who performs "thinking", and this "me" as the subject cannot be doubted, and this "me" is not a "me" of the extended flesh. It's the me of the thinker. So, it is paradoxical to deny one's own existence.

- This is just self-deception.

The basis of this theory, "I think, therefore I am," is not very reliable, because the formula is based on the hidden assumption that "the mind is a self-consciousness." If self-awareness is abandoned. Then Descartes' argument fails.

However, for Xiao Lan, when he came from the main god space, he entered the hypercube of the movie world of the extradimensional killing array, and then jumped from the hypercube, a quantum world constructed by humans with science and technology, to the real world where humans are located, and by invading and creating chaotic fetal movements, the world summoned the "place of constraints" where the beginning and the end are the same when launching a passive counterattack, so that one of the chosen ones, Carl, read the Akaxia record burned on the root, so as to recover this memory that caused the hero's fall and collapse, he got the truth of the beginning of the birth of this world:

The Creator of this world has definitely appeared. And leave a whole trace of the creation of the world.

"Well, the Earth part is set up. The largest technology companies are secretly researching quantum transmission technology and conducting experiments, this setting basically does not see any problems, and the solar system can be constructed according to normal thinking, but beyond this, my current authority is not enough, and my own cognition is not enough to shape a universe with a complete history, so it's okay, only shape gold outside the solar system, and then place a four-dimensional enclosed space similar to a Klein bottle, anyway, human technology cannot reach that area......"

Is this real? It should be so, Xiao Lan asserted.

But even so, after destroying both the Earth and the Moon, he boarded a warp spaceship and headed for space, to witness the true face of the end of the world.

With a speed of more than 1,500 times the speed of light, she and Xiao Lan and Flora crossed Pluto, which was expelled from the nine planets, in 26 seconds, and reached the Edgeworth-Kuiper belt of the outer solar system, heading towards the spherical cloud about a light year away from the sun and surrounding the solar system: Oort Cloud, Xiao Lan is using her own strength to protect the spaceship while constantly correcting her orbit so as not to hit a deadly planet headlong at 1500 times the speed of light.

Then it dawned on him that it was true...... Ignorance is bliss.

Telescopes on Earth can see the Milky Way and see the stars at night, but after the spacecraft has passed 12 billion kilometers, nothing has flown out of the solar system and it is pitch black.

And apart from the darkness when you look out, you can't see the sun when you look inside, because the sun's rays can't travel to 12 billion kilometers.

Hydrogen is probably the fundamental element in the solar system, and in objective fact only applies to the inner solar system, with a maximum range of 20 billion kilometers in diameter. The light waves produced by hydrogen fusion are extremely powerful in the solar system, and can travel up to 5 billion kilometers and reach 10 billion kilometers in rare cases. In other words, there is a big question about what kind of light the stars are seen from the earth at night.

In other words, all the extrasolar images that have been confirmed so far have been able to see the outside through a "channel" into 12 billion kilometers, or through the "Solar System Shell Telescope". In other words, there is a great deal of knowledge in the 3 billion to 10 billion kilometers of the solar system, and when it reaches 12 billion to 25 billion kilometers, the solar wind will also be blocked here, becoming an eggshell, and the thickness of this shell is 7 billion kilometers, as if it is a super huge telescope, and only within the lens can you see the scenery outside the solar system.

The picture of the universe and the Milky Way is only relative to the earth, and the earth is a well-designed "cinema". In fact, it is very likely that there is darkness outside the solar system, and it is currently estimated that there is only one solar system in the entire universe, which is our solar system and the only cosmic gravitational field.

- This is the reality of this world.

At a distance of 3 billion to 10 billion kilometers from the sun, Xiao Lan entered some kind of uncertain orbit dozens of times in succession and suddenly slowed down, and when they reached 20 billion kilometers, they felt like they were sailing in an increasingly dense liquid, not only did the speed start to plummet from 1,500 times the speed of light, but—

“…… What the hell is that? Why, why is there a tsunami in the universe? ”

When Pandora was swept into a huge black wave that slapped her head, drowning in a sea of darkness of nothingness, Flora muttered in amazement.

"It's not water, it's a wave with a super-dense compressed space, water pressure—no, it's the cosmic pressure!" Xiao Lan summed up the situation in a low voice, and at the same time, he quickly investigated the surrounding situation.

The results were not encouraging.

It seems that due to the drastic increase in space density, the curvature navigation of distorted space has been forcibly suspended, and the space pressure similar to water pressure is simply like the surface of a black hole, if Xiao Lan does not use his own strength to maintain stability under the huge pressure, all tangible and intangible matter will distort and collapse under this force until it is destroyed.

At the end of the world, there is nothing but nothingness.

But if that's all there is to it, it's not much expected.

But what Xiao Lan was hovering in his heart at this moment was another thought that made him tremble in his heart: the reality he observed, in the real world he was in, wasn't it the same?

The starlight that can be seen in the night sky, the cosmic scene outside the solar system, the mysterious solar system......

Could it be that the reality he lives in is actually just a tectonic world? (To be continued......)
