Those who face the wall, but are in the Nascent Soul stage.

Chapter 305 Retracing the Emperor's Path (4k)

Beijing.

The courtyard of the wall-facers.

Inside the room facing the wall, Luo Qing sighed and stared blankly at the ball of photons in his palm.

This cluster of photons is traveling at the speed of light along a black hole about 1.6 centimeters in diameter in the palm of your hand. According to the Schwarzschild radius formula, the mass of this black hole is approximately 6.67 × 10⁻⁶ kilograms.

That's exactly the weight of the Earth.

In other words, Luo Qing is holding an entire Earth in his palm.

To prevent the black hole from sucking the entire Earth in, Luo Qing directly severed the black hole's gravitational waves, so that its gravitational effect was only effective within a three-centimeter space near the black hole.

Gravitational waves are ripples in spacetime itself, propagating at the speed of light. If spacetime were a smooth surface, then massive objects would press holes into this smooth surface, and the spatial structure would contract toward the mass point. Anything existing within the spatial structure would be affected, including photons.

Moreover, from a physics perspective, gravitational waves cannot be destroyed in any way. The essence of gravitational waves is space structure, and space structure cannot be "destroyed".

The fall from a higher-dimensional space into a lower-dimensional space has nothing to do with the "destruction" of space. This "fall" is essentially the higher-dimensional space taking a shortcut in the lower-dimensional space.

There is only one way to make gravitational waves "disappear," that is, to restore the space of fluctuation to a flat state: make the gravitational source lose its own mass.

If the gravitational source is composed of normal matter, then one could try to annihilate it with antimatter, causing it to be completely released as energy.

If the source of gravity is a black hole, then it becomes more complicated. According to Hawking's no-hair theorem for black holes, a black hole is described by only three physical quantities: mass, angular momentum, and electric charge. Once matter enters a black hole, it will lose all other information. Whether it is matter or antimatter, there is no difference to the black hole; they are all treated equally.

For black holes, they're all equally delicious.

Black holes can only evaporate through Hawking radiation, which is based on quantum mechanics. Once completely evaporated, the spatial structure affected by the black hole will return to normal.

Luo Qing, however, forcibly straightened out the ripples in this space.

If you have enough strength, you can straighten out the folds.

In this way, the gravitational waves are abruptly cut off, and the spatial distortion caused by the black hole exists only in a space of 5 cm, without affecting the world outside.

From the outside, the event horizon of this black hole, which is the size of a glass bead, is 9 millimeters. The event horizon is the boundary where the escape velocity equals the speed of light.

In other words, within a 9-millimeter space of this black hole, photons will neither be sucked into the black hole nor escape from its gravity.

This is why the ball of light containing the black hole in Luo Qing's hand is about 3.4 centimeters in diameter.

This is exactly the size of a ping-pong ball.

Luo Qing had no way to intercept photons for the time being. Therefore, in order to study the properties of photons properly and find a way to travel at the speed of light, he went to great lengths and came up with this idea: to create a black hole to trap photons.

Research on photons has been successfully conducted.

The kid is silly, but he's strong.

Maintaining such a black hole is not easy.

Compared to the instantaneous black hole formed by the 360-gate solar spear attack that reversed the Great Ring back then, this black hole has a much larger mass.

First, there's the issue of the mass source of black holes. There are only so many planets and moons in our solar system, so it's not easy to gather enough matter to create a single mass equal to that of Earth.

You can't just break off a piece of the rings or Jupiter and turn it into a black hole.

That won't work.

In order to gather enough mass to form a black hole, Luo Qing went so far as to comprehend the mass-energy equivalence equation.

Scattered around Luo Qing were a pile of high-energy physics books, and his computer contained at least 20 gigabytes of physics archives. Almost all of humankind's research achievements in high-energy physics were on display here.

Luo Qing has been studying for several days now.

Now, in terms of pure theoretical knowledge in physics, Ding Yi may not be superior to him.

Two hundred years later, Luo Qing has returned to his position as a physics professor at Tsinghua University!
The top-level expert is back.

However, the more Luo Qing delved into the study of cutting-edge theories, the more confused he became. He felt that he might never learn how to fly at the speed of light in his lifetime.

As for mastering the mass-energy equivalence equation and creating black holes.

The mass-energy equivalence equation is one of the core formulas of Einstein's special theory of relativity, revealing the essential connection between mass and energy:
Mass is a concentrated form of energy.

The two can be transformed into each other.

[And energy equals mass multiplied by the square of the speed of light.]

Luo Qing knew that the annihilation of matter and antimatter could convert matter into energy 100%, which meant that energy could also be converted into mass, thus realizing the mutual conversion of energy and mass.

This is the correct way to apply the mass-energy equivalence equation.

Although Luo Qing could not find enough mass to compress into a black hole, he had enough energy.

He continuously released spiritual power outwards through his nascent soul, then converted the spiritual power into energy, and finally compressed this energy into his palm.

The nascent soul outputs Luo Qing's energy while simultaneously compressing it, repeating this process.

Repeatedly pounding the energy makes it chewy and delicious.

In the early stages of the Big Bang, extremely high energy density was transformed into the fundamental particles that make up matter, such as quarks and leptons. These particles further combined to form protons, neutrons, and atoms, eventually forming celestial bodies such as galaxies and stars.

Luo Qing is trying to reproduce this process on a very small scale.

I will demonstrate the Big Bang model by hand.jpg
Finally, as the density of energy reached a limit, the basic structures of matter, such as quarks and leptons, appeared within the energy.

In this process, Luo Qing also unexpectedly verified the correctness of the current cutting-edge theory, "string theory."

Although humanity has perfected "string theory" through the risk-reliever's grand unified cosmological formula model, theory and practice are two different things.

Humans only have theories, but Luo Qing has put them into practice, which is of extraordinary significance.

Luo Qing didn't keep the process of converting energy into matter a secret; he wrote a book about it and uploaded the relevant data to the internet, leaving the rest to scientists to analyze.

String theory is a theory that unifies gravity, electromagnetism, the strong nuclear force, and the weak nuclear force, and explains the nature of all elementary particles. Its core premise is that the fundamental units constituting the universe are not point particles, but extremely tiny strings.

A "string" is a one-dimensional vibrating energy wire.

The relationship between energy and matter is contained within string theory.

The vibration frequency and amplitude of a string directly correspond to the amount of energy.

The vibration modes of a string correspond to microscopic particles such as photons or gluons.

Strings are extremely small in scale and have extremely high vibrational energy, far exceeding the energy range of current human particle colliders. This is why string theory is currently difficult to verify directly, unless the risk-mitigators authorize humanity to open up the construction of a circum-equatorial particle accelerator.

No, the circum-equatorial particle accelerator may not be enough, and the circum-solar particle accelerator is probably far from sufficient.

The Circum-Solar-System Particle Accelerator could be a viable attempt at a rough verification of string theory.

Therefore, particle colliders have limitations.

But Luo Qing didn't. He could continuously compress energy.

Infinite energy is like infinite strings, and these infinite strings exhibit different vibration modes, frequencies, and amplitudes at extremely high densities.

Thus, under extremely high energy and pressure, matter resembling quarks and leptons appeared out of thin air in Luo Qing's hands.

Then atomic nuclei composed of quarks and leptons appeared.

But soon, these atomic nuclei were compressed into a neutron degenerate state by extremely high pressure. Then, the enormous pressure broke through the neutron degenerate pressure, and the matter collapsed into a tiny black hole.

Immense energy was transformed into negligible mass.

Luo Qing then began to repeat this step, and the minute mass began to accumulate infinitely.

Ultimately, the nascent soul within Luo Qing's body output a total energy equivalent to that of an Earth mass.
This formed the tiny black hole.

If Luo Qing didn't mind the trouble, he could continue to increase the size of the black hole, but Luo Qing no longer wanted to do that. The purpose of condensing a black hole was simply to ensure that photons wouldn't wander off.

After capturing some photons using a black hole, Luo Qing began his research on photons.

Even though Luo Qing understood all the properties of photons, he still couldn't figure out how to travel at the speed of light, nor could he completely transform himself into a photon state.

This made Luo Qing very pessimistic.

Perhaps Einstein's theory is correct: it is impossible for a massive object to reach the speed of light.

In Luo Qing's research, photons have no rest mass, always move at the speed of light, have wave-particle duality, and carry energy and momentum. Gamma laser beams are based on this principle for killing.

The reason why Luo Qing cannot transform into light and fly is quite simple.

Because he discovered that his transformation into a photon was irreversible.

Once the basic matter that makes up him becomes pure energy, that is, the stage from closed string matter to discrete string energy, Luo Qing can no longer control the "strings" that make up his own matter that have entered a discrete state.

At that time, Luo Qing will also turn into a ball of photons and continue to move at the speed of light.

The speed of light can never be stopped.

After realizing this, Luo Qing immediately stopped his attempt to transform himself into a photon.

This reminded Luo Qing of Shan Qing's death.

Shanqing's death was due to the massive antimatter attack from the Devouring Empire, which completely annihilated his own matter. The basic particles that made up Shanqing turned into photons and dissipated eternally, leaving Shanqing as nothing but a pure spirit that could not interfere with the material world.

This spirit is essentially a pure information entity and does not exist.

The reason Shan Qing could still appear before the world was purely due to the unique characteristics of the two cultivation realms: the "transformation into a god" characteristic of the [Transformation of the Divine Realm] and the "undying will" characteristic of the [Integration Realm], which preserved his remnant spirit.

In reality, Shanqing is completely dead.

Luo Qing was confident that by transforming himself into a pure photon state, he could control Photon Luo Qing to move in a certain direction, but the cost was that the movement of the photon would never stop, and Photon Luo Qing would soon be far away from the solar system.

If he's lucky, he'll wander the universe forever; if he's unlucky, he'll be sucked into a black hole and disappear forever.

This is not the light-speed movement that Luo Qing wanted.

Luo Qing's photonicization and Luo Qing's quantization are two different concepts.

Luo Qing is quantized; the fundamental particles that constitute Luo Qing still exist, but they switch back and forth between the existence state and the destruction state. Even if explained using string theory, it is just a different vibration mode of the string manifested by the superposition of particles.

However, Luo Qing's photonicization is irreversible. The essence of mass energy conversion is to completely transform a closed string into a discrete string. The characteristic of a discrete string is that it moves at the speed of light without stopping and cannot be restricted by any means except by space itself.

After repeatedly confirming this point, Luo Qing finally gave up the attempt at photonization.

Perhaps, traveling at the speed of light is just a dream that will forever remain unattainable for him.

After figuring all this out, Luo Qing gave a bitter smile. He looked at the black hole in his palm and, mimicking the process by which macro fusion collapsed itself into a quantum state, slowly collapsed this small black hole into a quantum black hole.

Only by doing this can we prevent this black hole from interfering with the macroscopic world.

In the past, this step would have been impossible because black holes involve general relativity, and there is an irreconcilable contradiction between general relativity and quantum mechanics. However, with the emergence of the grand unified formula of the universe and the summary of string theory, the contradiction between general relativity and quantum mechanics has been smoothed out by string theory.

Luo Qing already has the ability to convert this small black hole into a quantum state black hole without loss.

Furthermore, he has the ability to collapse the black hole from a quantum destruction state to a macroscopic existence state at any time as a means of attack.

After all, it's a little gadget that I spent a whole day compressing; I can't waste it.

Thus, after the quantum black hole collapses into a quantum state, it no longer has any impact on the macroscopic material world. In the quantum world, Luo Qing has already instructed the spirit swordsmen and Lin Yun to stay away from this little thing to avoid getting caught up in it.

Throwing out a black hole of Earth-scale size could destroy not only large rings of matter, but even the sun. However, Luo Qing, who possessed the power to destroy the sun, wasn't happy. Destroying the sun relied on the black hole's own power, which was essentially the effect of the laws of physics. It wasn't achieved by using his cultivation strength to sever a star with a single sword strike.

Moreover, Luo Qing still cannot travel at the speed of light.

After dealing with the small black hole, Luo Qing stood up.

He left behind a fragment of his soul, which continued to answer questions from netizens around the world on the message board, while he himself captured some free molecules in the air, combined them into plant fiber macromolecules, and wove them into a modern outfit and a sun hat.

Then, with a single step, he shrank the distance to an inch and walked out of the Wallfacer's courtyard.

Although he gave the excuse of going into seclusion, it is reasonable for him to come out and relax after his seclusion failed.

"What other way is there for me to travel at the speed of light?"

Walking down the bustling street, a glint of wisdom flashed in Luo Qing's eyes beneath his hat brim...

Before he knew it, he had arrived at the Chinese Academy of Sciences.

Looking at the plaque of the Chinese Academy of Sciences, Luo Qing had a flash of inspiration.

Since I can't figure it out myself, why not ask these scientists for help? Pooling our wisdom might lead to a solution.

With this in mind, Luo Qing entered the gates of the Chinese Academy of Sciences.

In 15 minutes, the Chinese government will issue an invitation to the global scientific community, inviting physicists from all countries to Beijing to jointly discuss the theoretical and technical issues related to "how a cultivator with rest mass (Luo Qing) can achieve light-speed flight".

Two hours later.

"Damn it, I don't believe that so many people can't come up with a solution."

Wearing a sun hat, Luo Qing hid in a corner of the Great Hall of the People, watching the more than one hundred Nobel Prize laureates in physics file in and said angrily.

If all of humanity cannot come up with a solution.

Then Luo Qing can only try to follow in Jiang Renhuang's footsteps.

A space for beatings.

However, Luo Qing is only at the Nascent Soul stage, so it's uncertain whether he can succeed.
