Generally speaking.

At the end of their lifespan, a star with a mass of eight times the mass of the Sun will stop fusing at its core.

Coincidentally, if the overall mass of its core is above 3.2 times the mass of the sun, then a gravitational collapse of extremely frightening strength will occur.

After the collapse, it has successively experienced a degenerate state and a neutron state, and if the star's inner core is still unable to resist the massive gravitational collapse from itself, then a primary black hole will be formed at the center of its mass.

As soon as a black hole is born, it immediately devours everything within its event horizon.

During the devouring process, the outermost layer of matter is violently thrown out, and the matter close to the event horizon is absorbed by the black hole and falls towards it in a spiral.

During this process, the matter is heated and emits a large amount of infrared rays and electromagnetic radiation, and eventually falls into the field of vision and is swallowed.

Similarly, if the mass is not met, aging stars that have reached the end of their lifespan will collapse into neutron stars, a type of star between a white dwarf and a black hole, after a supernova explosion caused by the collapse of gravity.

Therefore, neutron stars are the densest stars in the universe except for black holes.

Although white dwarfs are dense, they are still within the maximum density range that can be achieved by normal material structures.

However, the pressure of neutron stars is so great that even electrons will be compressed into the nucleus of atoms, neutralized with protons to become neutrons, electrons escape, and the atomic volume collapses hundreds of billions of times to become composed of only neutrons.

And the whole neutron star is formed by countless neutrons next to each other.

It can even be said that a neutron star is a huge atomic nucleus, and the neutron star density is the density of the atomic nucleus.

In such a situation, the pressure at the very center of the neutron star will be incredibly strong, billions of times more terrifying than the core of the Sun.

Generally speaking, the protons and neutrons that make up the nucleus of conventional matter are made up of three quarks.

The proton is (u, u, d), i.e., it consists of two upper quarks (u) and one lower quark (d).

The neutron is (u,d,d), i.e., consists of one upper quark (u) and two lower quarks (d).

However, in the core of a neutron star with an extremely high density, in a terrible environment beyond the realm of human understanding, the neutrons will be completely crushed by a terrifying pressure so strong that a (ud→su) quark phase transition will occur, thus forming a (UDS) quark cluster composed of a large number of upper quarks, lower quarks, and strange quarks.

S here refers to the Strange Quark, so the (UDS) Quark cluster is called the Strange Substance.

This kind of high-temperature quark fluid, which is only accidentally produced in extreme environments, has an extremely large gravitational negative pressure, and even exceeds its own energy density (gravity).

In other words, the gravitational pull of the strange matter has a strong repulsive effect, and even the surrounding space is strangely and violently distorted by it.

It is precisely because of the dangerous property of strange matter, which can greatly change the curvature of space-time, that warp navigation beyond the speed of light in a vacuum is established.

And at this very moment.

Exuding ultra-high temperature and ultra-high pressure, this strange mass of matter that could induce the destruction of the entire Blue Star with just a small piece of it lay quietly on Mu Pao's long and slender palm, completely unable to show even the slightest bit of his violence.

"Wonderful power."

Mu Cang squinted slightly, looked at the strange mass of strange matter emitting blazing light in his palm, and gently poked out a trace of divine thought to penetrate into it, and began to study it carefully.

He wants to study the underlying workings of strange matter, and then perfectly reproduce it by manipulating the fundamental forces.

After possessing the four basic powers, Mu Cang has become more and more aware that this is a universal power.

As long as there are substances and phenomena in the universe, as long as you understand how they work, you can reproduce them at will.

At the same time, with Mu Cang's move, the surrounding 100,000 miles of time and space also changed suddenly.

Sometimes it swells, sometimes it collapses.

Sometimes spiraled into bundles, sometimes condensed into rings.

With the emergence of these complex changes, a large number of high-energy rays carrying unknown energy emerge from the surrounding space-time and explode out of thin air every minute and every second, polarizing the already sparse material particles around them into large clusters of dazzling light clouds similar to crystal lattices, and the deep space within a radius of 100,000 miles is like a beautiful scenery of a falling immortal garden.

But no one knows, in fact, this seemingly beautiful and gorgeous fairy scene is extremely dangerous.

If a planet accidentally orbits here, it will quickly collapse and disintegrate from the most basic level of matter in an instant under the influence of countless chaotic space-time turbulence, turning into a large asteroid belt containing countless high-energy charged particles.

However, Mu Cang, who is located in this turbulent time and space for thousands of miles, will not care about this.

After ten minutes, he had fully understood the operation mechanism of various physical effects of strange matter, and at the same time, because of his deep knowledge of time and space, curvature, and dimension, he used it as a portal to solve the knowledge all the way, and finally fully mastered the entire physical operation process of warp speed navigation.

"The first is the Casimir device for providing negative energy."

Waving his hand to disperse the strange substance in his palm, Mu Cang raised a finger and lightly tapped it at the void in front of him.

Buzz –

The surrounding space-time shook violently, and trillions of high-energy particles emerged out of thin air.

As soon as these particles appeared, they spontaneously converged, and under his will, countless particles around them swished and quickly built a circle of unimaginably complex and precise from the microscopic level, and once it was born, it bloomed with blue and white brilliant translucent devices.

"Then, simulate the physical effects of the strange substance, dock with the Casimir device, and generate a warp bubble."

The surrounding space swelled with ripples visible to the naked eye.

Between the rolling waves, a distorted space with a diameter of ten meters and a wide range of soft light appeared, completely enveloping Mu Cang.

If you look at it normally, then he looks like he is just wrapped in a mass of Lorentz manifold 'bubbles'.

But if you look at it from a higher dimensional perspective, then around Mu Cang in the 'slender' three-dimensional world like a calm sea, at this time, the same 'slender' but extremely regular arc-shaped waves suddenly rise with convex front and concave back.

This circle of waves that completely envelops him is the warp bubble.

Compress the front space and expand the rear space.

The axis formed by the front and rear is the direction of navigation.

Inside the 'bubble' is a straight space, and Mu Cang in it does not really move, but is carried by the warp bubble.

Therefore, in warp navigation, the objects in the 'bubble' will not be affected by any inertia.

The 'fuel' consumed to achieve this process is the negative energy extracted from the exotic matter.

"It's time to go."

Mu Cang looked at the vast starry sky in front of him, and a rare fluctuation rose in his heart.

Because this time, it was not a faster-than-light travel with the help of the spirit world.

It was the true faster-than-light travel he had been thinking about for a long time.

Buzz –

The warp bubble that was holding a large cloud of negative energy in front of him and tightly wrapped Mu Cang immediately activated, leaving Pluto and galloping towards the blue star billions of kilometers away.
