Chapter 942 874: The Birth of the Mass-Energy Equation!

Lin Ke was writing furiously, both hands working together, leaving afterimages on the paper, with his eyes emitting a remarkable white light."The speed of spherical light emitted by any light source is isotropic in every inertial reference frame and always equals c, and the laws of physics are the same within all inertial reference frames."

"The actual mass of an object is the sum of its rest mass and the extra mass gained through motion. When an external force acts on a free particle at rest mass, the increase in kinetic energy as it undergoes displacement is..."

"If the external force is in the same direction as the displacement, the above equation becomes... According to the Lorentz transformation, the formula for mass transformation is..."

The magic power within him flowed continuously without diminishing, and in this massive consumption, some formulas were immediately derived and simulated by him.

Mass, energy.

Mass, energy.

Mass, energy.

Right now, Lin Ke's entire mind was filled with formulas, theorems, phenomena, results, proofs... all concerning mass and energy!

For an object, if you cut it in half, do the sum of the masses of these halves and the original whole's mass weigh the same? But is this really the case?

Perhaps the change in mass is just due to measurement inaccuracies?

How about starting from the microscopic level?

An iron atom contains 26 protons, 26 electrons, and 30 neutrons.

However, the mass of the iron atom is less than the sum of the mass of a standalone iron nucleus plus 26 electrons, also less than the combined mass of 26 protons and 30 neutrons.

Why is this?

Energy is released when electrons, protons, and neutrons combine into a nucleus!

And this energy comes from the conversion of mass, so the components of the iron atom lose mass in the process of forming the iron atom.

The sun is similar too.

About three-quarters of the sun's mass is hydrogen, with most of the remainder being helium, and the temperature at its core is as high as 16 million degrees with significant pressure.

Under these extreme conditions, nuclear fusion occurs between protons—two protons provided by hydrogen atoms combine to form a deuterium nucleus.

The deuterium nucleus then combines with two more protons successively, forming a helium-4 nucleus, and the mass of the helium-4 nucleus is only 99.3% of the mass of the four protons that formed it!

This means 0.7% of the mass has been converted into energy and released.

In the process of forming each helium-4 atom, about 28 MeV of energy is released.

A helium-4 atom is so light it can almost be ignored, but the sun produces 596 million tons of helium-4 per second, the energy generated in the process is astonishingly huge.

So all of this reveals the conversion relationship between mass and energy!

Mass can create energy, and energy can similarly create mass.

The mass of an object is divided into rest mass and motion mass. Motion mass is related to speed: the greater the speed of the object, the greater its mass.

Thus, if we increase the speed of an object, it will contain more energy, making it possible to convert into other objects with greater rest mass.

For example, if we accelerate two electrons to a sufficiently high speed and make them collide, a new pair of particles can be produced!

One matter particle, like an electron, muon, proton, etc., and one antimatter particle, like a positron, antimuon, antiproton, etc., are thus created, and the rest mass of this new pair of particles is greater than the rest mass of the two electrons.

This is the essence of the mass-energy equation!

An equation identity lies in the arbitrary conversion between the sides of the equation.

And the mass-energy equation represents that the mass and energy on both sides of the equation can be converted into each other.

This is where its terror lies.

"Mass and energy..."

In Lin Ke's mind, various experiments concerning the two were simulating, colliding.

In an instant, hundreds of thousands of experiments were ongoing simultaneously, all based on the actual situation of Naseng.

From gaining weight after eating food to the microcosm of atoms and electrons.

From cutting through lines of magnetic force to the depiction and application of magic and skills.

All the motives, progression, and results of these experiments were simulated in Lin Ke's mind and then written down on paper.

Originally, the paper drawers connected to all the paper mills should have extended infinitely, with the amount of paper inside decreasing at a visibly perceptible rate.

If it weren't for Naseng already being considered an industrial magical society, Lin Ke alone might have used up the amount of paper a country would consume in a past life.

Fortunately, once those paper mills discovered the paper orders from Great Wilderness University, they immediately began production, so the paper in the drawer on Lin Ke's desk was always sufficient.

At the same time, all of Lin Ke's derivations and experiment results were documented on paper, the dense manuscripts stacking from one corner of the wall to another.

The entire room was almost submerged in paper!

The dark blue pen in his hand operated at full speed, with strands of feedback merging into it.

The dark blue pen experienced a whole new transformation amidst Lin Ke's furious writing.

And at a certain point in time, someone quietly entered this room.

It was John!

The changes in the entire Magma Territory could not escape John's attention, not to mention a major event like the lockdown of Great Wilderness University.

John naturally deduced the reason for this event.

So, regardless of how important or urgent the outside matters were, he put everything aside and returned to Great Wilderness City.

Subsequently, he meticulously organized Lin Ke's densely filled manuscripts and stored them in the Space Ring.

And he placed a cup of warm Gula Milk within Lin Ke's habitual reach.

Not uttering a word, for more than a month no actions could be seen.

John quietly stood behind Lin Ke, helping him organize things, adding milk, or placing some snacks.

Lin Ke was deeply immersed in the ocean of derivation, his body reduced to mere instinct.

If anyone else came here, even Rica, Fulon, Ove, and the like, they'd probably unintentionally disrupt Lin Ke's state.

However, it was John who came here.

Since childhood, Lin Ke suspected even he didn't know his habits and preferences, but John knew.

So, Lin Ke's very instincts had grown accustomed to John's presence.

Thus, Lin Ke unconsciously picked up the Gula Milk and drank it, unconsciously ate a piece of sour milk cake, unconsciously handed the drafts to John.

After John's arrival, Lin Ke's derivation speed was also enhanced.

John was, after all, the [Butler]!

Skills—Assist!

Skills—Coordinate!

Only John could help Lin Ke with his abilities without waking him up.

For others, even if Knicks came, that kind of healing magic would likely make Lin Ke aware and alert.

Thus, with John's company, Lin Ke's speed got faster, and faster, and faster...

Until two days later, John's statue-like body moved slightly.

For he noticed that Lin Ke's pen had stopped!

Lin Ke stretched deeply, then the eyes as if they were suns, looked towards John behind him:

"Huh? John? When did you get here?"
