Observation, conjecture, and proof are the basis for science to establish a logical chain.
When I first arrived, I only had specious and incomplete memories of the demon spirits. I didn't even have anyone new to talk to, so I had to start from the very basics.
There is no light in this world.
Fortunately, the slits that have been upgraded to regular standards do not need light in the first place.
It can link to the sea of consciousness and directly convey the content filtered by the slit.
However……
No, nothing.
The slit swings and swings, just like throwing a fishing net into the water, and usually something will be fished out.
However, in this weightless world, Su Xingmu swayed left and right, flipping up and down, but still found nothing for a while.
If not, then change the fishing net to a larger or smaller mesh.
The slit is not a fishing net. It can be changed in size at will, which is more convenient.
Now from the nanometer level up, ten nanometers, hundred nanometers, micrometers, silk meters...
Nothing was found.
And from the nanometer level down, emmeter, picometer, femtometer...
Still found nothing.
Including the mist that is obviously visible to the naked eye, it is also stirred up and down by the slits, but the feedback result is still...
Nothing at all!
"How can it be?"
Su Xingmou, who was tossing and turning, wondered aloud, there were no atoms, molecules, viruses, bacteria, etc., and there was no such obvious black mist?
Unwilling to do so, he fished left and right, making the slit expand until his head grew bigger...
But even though the shape is so obvious, once you fish it out, there is still nothing in the slit!
"What's going on? It's like a monkey fishing for the moon!"
While Ye Han was running his brain, freezing wounds, regulating nerves, and repairing his body, he looked at Su Xingmou strangely.
"Why are you looking at me like that? You can't even complain when things are so troublesome?" Trumpet No. 1 glared.
"What are you looking at? Still looking! Still looking! Look again, I, I, I...I won't do it anymore!" Trumpet No. 2 flipped the table.
"Alas, since my fate was exposed, my luck seems to have run away... I can't do anything, and you are still being implicated and suffer along with me." Trumpet No. 3 complained sadly.
"Let's see...what do you mean? Do you want to have a round here and take a two-day break to recuperate?" Trumpet No. 4 said.
Ye Han let out a long sigh.
There was so much nonsense, and not a single sentence hit the point. The correct answers were all spoken, but they slipped through perfectly.
"It slipped by?" Su Xingmou wondered, calling up the Heart Demon Computer applet and flipping through the chat history sentence by sentence.
Weekend? It seems not.
Luck? Probably...not really.
Quit? Complain? This is even more irrelevant.
Monkey fishing for the moon? Until this sentence, Su Xingmou finally had a little feeling.
The fog in this world was hazy. When she waved the slit to scan, it was like a monkey fishing for the moon. She could see really clearly. When she swiped through the slit, nothing was gone...
Once or twice is luck, but eight times out of ten is obviously a setting.
After all, more than ten years of hard study in Hanchuang were not in vain. She soon thought of something related - the theory of cosmic holographic projection.
This world, from the mist, to the spirits scattered in all directions, to her and Ye Han, are not real, they are just different types of projections.
So it looks decent, but once you have to use a slit to measure it, it's like a bamboo basket can't hold water, you can't catch light with your bare hands, and you can't catch anything.
It kind of means that.
But that's just a little bit.
The theory of cosmic holographic projection is not unique, it is actually a matter of horizon.
Speaking of event horizons, we must talk about black hole event horizons.
If a person falls into a black hole, according to the current information conservation theory, it will leave a permanent two-dimensional projection on the surface of the black hole, but at the same time, it will also pass through the event horizon and continue to fall into the black hole...
Contradictory?
There is no contradiction. The inside of the black hole is a three-dimensional person, and the surface of the black hole is all the information about the person encoded in a two-dimensional way.
On the horizon of the black hole, there are high-dimensional strings full of energy, so the moment it penetrates the horizon, the person is actually burned to ashes, and all the information carried is quantized and entangled.
From then on, the messy two-dimensional information left on the surface of the event horizon is the ontology, and what continues to fall into the black hole is just the projection of the two-dimensional information in the black hole...
So people can exist on the surface and inside the black hole at the same time.
Well, this is just the foreshadowing.
The theory of cosmic holographic projection says that our observable universe actually has an event horizon just like black holes.
The difference is that the event horizon of a black hole is a spherical surface from which light cannot escape, while the event horizon of the universe is a spherical surface from which light from the outside cannot reach the inside.
It's like...a flipped universe.
So, does our world really exist?
Or is it simply a holographic projection projected from the information on the horizon surface of the universe?
"This...even if it is really a projection, you can't tell it at all, right?" Su Xingmou expressed confusion.
There are still methods. If it is really a projection, the minimum storage unit of the universe horizon is one Planck length.
According to the holographic principle, the amount of information contained on the outer surface of the universe must be equal to the information contained in the interior of the universe.
The volume of the sphere must be much larger than its outer surface, so if you want the two information to be consistent, the resolution of the material inside the sphere must be much rougher than the Planck length.
That's why we have that saying, a holographic universe is a fuzzy universe.
Therefore, the simplest and most direct way to detect whether the universe is holographic is to measure the resolution of the smallest unit of internal space-time. If it is as fine as the Planck scale, it should not be a projection. If not, the possibility is very high.
In fact, the reason why the holographic universe theory was proposed is because some cutting-edge laboratories have detected unusual noise close to this level, which means that the resolution of the real world does not seem to be as fine as imagined...
Of course, because it is an operation at the limit of human capabilities, various vibrations, noises and even changes in the rotation and revolution of the earth and the gravity of the stars may cause errors.
Therefore, it has not been able to achieve sufficient confidence so far, and it is only spread in a small range.
Otherwise, I would have concluded that I would have wanted to go to Ure or SCE, but the reason why I didn’t go to Cell was because I didn’t have the right major... maybe I would have won a few Nobel Prizes.
"So, by using the catastrophe to cross my natal bridge, you actually shot us at the edge of the universe..."
Su Xingmou tried her best to understand Ye Han's words.
"So now, we are... dead? Have turned into a QR code on the wall of the universe?"
As expected of Han Chuang who had studied hard for so many years, Su Xingmou was really no longer a fool and had completely caught up with his ideas.
"It's definitely not a QR code. I've already tried it. Look." Ye Han shook his head seriously and casually folded the long slit into a Möbius strip.
You cannot create a Möbius strip in the two-dimensional world, just like you cannot create a Klein bottle in the three-dimensional world.
But this world only has three dimensions, because Ye Han immediately tried the Klein bottle. Since entering the third realm, dimensionality is not a problem.
But in this world, he can't break it.
This is a three-dimensional world, a simple and pure three-dimensional world.
This is also consistent with the holographic cosmology. According to the deduction of the holographic cosmology, although space and time are multi-dimensional, endless, and weird, its external manifestation is still three-dimensional, which is not too strange.
But in this case, what about the multi-layered world in the main world that is like a layer cake and can accommodate Klein bottles?
After hearing Ye Han's answer, Su Xingmou was not satisfied and immediately said:
"Even if it's not a QR code, it's possible that we are just a projection in the black hole, and the body is still attached to the event wall..."
This... is indeed possible.
If it becomes a QR code, the world will be extremely detailed, and nothing should be gained. Only three-dimensional projection can do this.
After studying hard for ten years, Su Xingmou is not so easy to fool.
But the three-dimensional projection cannot explain why this place is so dark...
At the edge of the universe, the expansion of space-time exceeds the speed of light, resulting in a horizon where light cannot enter. This is why there is no light source at all, because in the process of entering the eye, the light is torn apart by the expansion of space-time.
And if the three-dimensional projection is not on the horizon, it should not be completely black, but there should be light.
Ye Han casually used energy to light a fire.
The light suddenly appeared, then dimmed and fainted.
Even so, it can be seen clearly and the light is still there.
Just like a candlelight, the brighter it is, the farther it shines; the darker it is, the closer it shines...
Once it exceeds a certain limit, it disappears completely.
It obviously doesn't comply with the three-dimensional inverse square law, but it doesn't look like it was torn apart, but more like it was suppressed or absorbed.
The situation here is really inexplicably weird.
It's like there are contradictions everywhere, which are difficult to match with existing theories...
"Ah! I really want to see something!" Su Xingmou suddenly waved the slit and exclaimed.
She didn't need to tell her, the slit was directly connected to the mind, and Ye Han also saw it.
The moment the light flashed, mottled and sparse light suddenly flashed through the wide slit.
That's not a photon. The slit can capture photons, but certainly not with the current resolution.
It appears that the light has excited the matter here.
Before there was light, even if the slit detected matter by law, it did not require the intervention of light. In this world, it seems not enough...
One possibility is that this situation is also caused by laws and conflicts with the Slit Law.
Just when Ye Han and Su Xingmu interrupted to brighten the light and see more clearly through the slit, suddenly there was an unusual fluctuation in the void——
"That big demon is over there, right over there! It's still talking inexplicably..."
"Ah ah, there is light, there is light, do you see it? Do you see it?"
"Is it possible that the spiritual vortex hasn't dispersed yet?"
All the demon spirits in the sky that had just escaped suddenly turned around again for some unknown reason, swarming in groups with a fierce momentum.
Although it was pitch black all around and I couldn't see my fingers, their heartbeats couldn't be hidden at all.
