It is shocking and soul-stirring. Even the cosmic affinity cannot tell the truth from the false. On the contrary, it makes people more and more intoxicated. It feels like the life and death of the universe are under control, and it feels like billions of time are just a snap of the fingers.
One flower and one world, one leaf and one bodhi, one thought and all things arise...
Everything is under control, and reversing time and space to manipulate life and death is nothing more than looking at lines on the palm of a hand.
However, the intoxication only lasted a moment, even though it was a hundred years ago. Ye Han quickly got rid of the overwhelming infusion of the world's will, detached his spiritual thoughts and calmed down.
It’s not that the world is really repairing!
It’s not like he incarnated into millions, united with the universe, and suddenly reached the highest state of spiritual practice!
This is a test of your character!
The gift before death may be a kind word to the dying person, but it may also be a gift to the person who is about to die.
And it may not be malicious, just like a whale sinking to the bottom of the sea, it looks magnificent and spectacular. If you get too close, you will inevitably be affected and be sucked into the bottom of the water together... But you can't watch it from a distance, but don't play with it.
It has nothing to do with good or evil at all.
If the death of a whale is like this, how much more the fall of a universe?
If he gets entangled and trapped too close, Ye Han may be forever lost in the pleasure of controlling time and space and manipulating the world!
Moreover, the stronger the practitioner, the purer his spiritual thoughts, the firmer his will, and the more unable he is to extricate himself.
But how could Ye Han break free so easily?
It's very simple, because the scene before me is completely in line with scientific principles.
People usually don't get too obsessed with things within their cognition.
The scene in front of you is like theoretically, as long as you fly fast enough, faster than the speed of light, you can follow the timeline and see everything that happened in the past of the universe.
It's just that it's not a time rewind at the speed of light, but a time rewind at the black hole's horizon.
Therefore, wild beasts from ancient times do not come back to life, but die and decay and turn into withered bones; trees and flowers either regain life or wither and wither normally; building bridges will not be repaired by earthquakes, but will collapse with roar...
It's rewind mode.
But before that, it was the string of law that broke first, and then the earth shattered, the sea water split, the moon turned into slag, and the obsession with dying created all kinds of strange phenomena, making the world full of ghosts walking at night, and demons dancing wildly, like hell...
…
The brain automatically turned the retrograde time forward. Ye Hanhan quietly browsed the records of the demise of the world, sighing in his heart: No matter which explanation of fire wall, appearance, or soft hair is closer to the truth, there is indeed no problem with the theory of black hole horizon. No wonder it happens.
become mainstream.
Of course he is not here to enjoy the scenery, but to do research.
Black holes are one of the ultimate problems in astrophysics and even physics!
That’s why Hawking’s creation of Hawking radiation is famous all over the world, his detection of gravitational waves, and his photos of black holes often shock the world.
However, just as quantum mechanics has deepened layer by layer from scratch, one revolution and two revolutions in string theory have constantly refreshed cognition... The black hole theory has also gone a long way from its formation to its gradual clarity.
At first, after scientists calculated that a black hole is a singularity, they believed that although it is a macroscopic object, it can be simply defined by three parameters: energy, charge, and angular momentum, similar to microscopic particles.
It was not until Jacob Bekenstein, the junior brother of Hugh Everett [the proposer of the Many Worlds Interpretation], that he proposed the black hole entropy formula in 1972, making black holes no longer so simple.
Black hole entropy explains some things, but it also brings new questions: Theoretically, if a black hole has entropy, it should emit radiation. But... isn't it that no matter can escape from a black hole? How can there be radiation?
At this time, disabled person Hawking stood up faster than anyone else, came up with Hawking radiation, determined that the "surface area of a black hole is entropy", and solved this problem.
But new problems arise.
According to this explanation, Hawking radiation originates from the fluctuation of vacuum particles near the black hole's event horizon. It occurs when one of a pair of virtual particles is swallowed by the black hole and the other flies away from the event horizon.
But this radiation is random and does not contain information. As the black hole's radiation evaporates, the original star's information will disappear with the evaporation. But according to quantum mechanics, information will not disappear inexplicably.
This is the famous "black hole information paradox".
Hawking believed that the information was lost, while the other party believed that the information would definitely not be lost. For this reason, the two parties also made a famous bet, until 2004, Hawking admitted that he lost.
However, the conclusions that Hawking reached through complex topological calculations at this time were not widely recognized.
Until 2012, four theoretical physicists from the University of California proposed the "black hole firewall" theory, speculating that separated entangled virtual particles would be destroyed by the firewall the moment they passed through the event horizon.
Then in 2014, Hawking came up with the apparent horizon based on the fire wall theory, believing that this is the true boundary of the black hole. Information will be temporarily trapped by the horizon, but will eventually be released, so the black hole is not black and should be called a gray hole.
At this point, the fire wall theory can be declared over...
But it was not overthrown by Hawking's new theory, but refuted by Ye Han himself.
What he saw at this moment was the scene where the black hole information was trapped by the apparent horizon...
Nothing is easier than empirical evidence to disprove a theory!
It is better than the Riemann Hypothesis. As long as a counterexample appears, it will collapse and collapse, making more than one thousand and hundreds of theorems and laws based on it come to nothing.
However, to rely on physical sensations and eye observation to understand and decipher such mysteries, there should be no scientist in the past and present who is as extravagant as Ye Han.
Well...the story of black holes is not over yet.
In 2016, two years before Hawking's death, he and two other scientists came up with the soft hair theory.
This theory is related to the progress of quantum field theory and string theory. In fact, the progress of many theories often depends on the advancement of theories in other fields.
Previously, it was believed that black holes are hairless because the three parameters of black holes correspond to the three laws of energy, charge, and conservation of angular momentum. There can be no more and no less.
However, the latest quantum theory research shows that there are countless conservation laws in quantum vacuum, allowing countless degenerate vacuums.
The three Hawkings extended this theory to the study of black holes, and created countless hairs for the black hole. The process of entanglement and radiation of virtual particles in the black hole will add a soft photon to the black hole and stimulate a hair that records all the information of the particles falling into the black hole.
of soft fur...
It is not possible to determine which one is correct between the apparent horizon and the soft hair theory.
But Ye Han hopes it will be the latter.
Because only in this way can he have the opportunity to pass on the information and let the main body know the mystery here.
Although the former is possible, it requires waiting. It takes a long time, and it may even be the measure of the birth and death of the universe...
That's right, what is browsing in the black hole at this moment is only Ye Han's soul, not his body.
Out of body experience?
He hasn't reached the stage where his soul can exist independently from his body, right?
Yes. But he has a golden body, which can be the perfect carrier of the soul just like the original body.
So at this moment, most of his soul is in Jin who entered the black hole for close reconnaissance, and only a small part of the main body of the control hall retains the incomplete survival instinct.
It would be best if the catastrophe of a black hole can be passed smoothly. If not, at least a glimmer of hope can be preserved.
But first, we still have to collect data, study phenomena, open our minds, and understand the truth about black hole horizons and the rules of information radiation.
Otherwise, no matter how exciting the rewind is, no matter how many things you learn, it will be useless if the news cannot be spread.
The black hole's information shielding even cuts off the connection between souls. Not many big names in the world can penetrate it freely. Time is really tight and the task is heavy.
==========
According to the deduction before entering the black hole and the verification in many previous worlds, string theory is basically correct.
There are eleven dimensions in the world, but most of them are curled up.
The earth in the end of time and space is curled up into six dimensions, a three-dimensional space on a five-dimensional membrane.
In other universes, the number of curled-up dimensions may be completely different, and the contents of the curled-up dimensions may also be completely different, giving mass and material dimensions; giving ideas and spiritual dimensions; giving world magnification the dimensions that connect the macro and micro...
The combinations are endless, and the values and order influence each other.
As the saying goes, pulling one hair affects the whole body, but here it is necessary to pull every hair of yours, and the reaction of each hair is different, and even the order of pulling will affect each other...
In this way, you can imagine how difficult it is to reversely decipher the pulling sequence through body movements and use this as a signal to send messages to the outside world!
Fortunately, Ye Han did not start from scratch. Mathematicians had already laid a solid foundation for this work.
This basis is called the Calabi-Yau manifold, which is a compact n-dimensional K?hler manifold with a first representational class of 0.
The conjecture was proposed by mathematician Calabi in 1957 and successfully proved by Yau Shing-tung in 1977.
Originally this was just a very abstract mathematical theorem that studied the metric space structure of manifolds, until superstring theory physicists discovered that this manifold just describes how six dimensions curl up and flip in the smallest scale quantum space.
!
Of course, a theorem is just a theorem.
Even if they have mastered Niu San, describing mechanical phenomena is still difficult for countless middle school and high school students.
The same here, the Calabi Yau manifold is just a mathematical tool, not a result. If you want to describe reality based on it, you have to bring in the cosmological constant for accurate solution.
Moreover, the Calabi-Yau manifold is most suitable for the curled-up six-dimensional ending universe. If you want to adapt to the fallen world, you need to reconstruct the theorem ontology...
Ye Han fell into deep thought.
Well, he has been meditating all the time, countless sparks of inspiration are running around in his mind, and he has never woken up, whether it is the clone or the main body.
Suddenly he woke up from his reverie, his unfocused eyes focused.
A familiar yet unfamiliar face appeared in front of him.
Familiar because he has long understood the shady and concave structures, the straight and comfortable proportions, and the delicate and smooth textures.
To say it was unfamiliar, it was because under his full vision, he saw the soul network beneath the surface. It was like the active neurons in the brain, or it was like the cobweb picture of the universe, flickering on and off, connected by currents, and magnificent.
Unspeakable.
Ye Hanqing couldn't help but reached out and touched it...
