The Science Fiction World of Xueba

After arriving near the wormhole, the Eternal Night spacecraft went through several days of orbit and attitude adjustments.

"All staff, please take their positions. In ten minutes, the Eternal Night spacecraft will pass through the wormhole."

"The No. 10 attitude adjustment engine starts..."

"The No. 2 capital adjustment engine starts..."

"The No. 5 capital adjustment engine starts..."

The Eternal Night spacecraft slowly turned its huge hull, aiming its bow at the wormhole 100,000 kilometers away.

"Pay attention to maintain the output power..."

"The attitude is good, the main engine can be started..."

"Eternal Night...forward three..."

The tail of the Hall thruster emits a blue-purple light, ejecting a high-speed plasma stream behind it, and the spacecraft starts to start at full power and enters an acceleration state.

"One hundred thousand kilometers away from the wormhole!"

"Fifty thousand kilometers."

"Ten thousand kilometers."

"A thousand kilometers."

"Ten kilometers."

"Contact countdown, ten, nine, eight, seven, six, five, four, three, two, one..."

Pang Xuelin and the others are located in the front third of the main shaft thruster of the Eternal Night.

Therefore, they could clearly see that the moment the bow of the Eternal Night came into contact with the wormhole, the dark space on the surface of the wormhole was like a stone being thrown into a calm water surface, causing a circle of ripples.

But this kind of scene only stayed in Pang Xuelin's eyes for less than two seconds, and then they plunged into this bizarre world.

The soft white light from the lights inside the spaceship was suddenly broken down into a rainbow of colors.

Layers of ghost images were created in the space around the bridge, and all the equipment in the spacecraft gave him a huge sense of depth and inclusiveness.

Although Pang Xuelin has already felt the sense of depth brought by the infinite space in the high-dimensional space in the wormhole, when he experienced this scene again, he still felt a dreamlike feeling.

This was especially true for Murphy, Billy, Little Brand, and others. They fixed themselves firmly on the seats one by one, and looked at everything around them in horror.

Fortunately, this process only lasted a few minutes.

It was much shorter than the last time when Pang Xuelin traveled through the wormhole in the rescue capsule.

With the slight shake of the spaceship, the colorful lights dissipated instantly, and the objects in the spaceship that showed an endless sense of depth seemed to be dominated by some kind of force and instantly returned to their original shape.

Outside the porthole, golden light came in and shone on the podium.

Pang Xuelin unfastened his seat belt and came to the porthole first.

Murphy, Little Brand, Dr. Mann, Billy, Emond and others came behind him one after another.

"my God!"

Dr. Mann couldn't help but draw a cross on his chest, looked at the black hole that was emitting hot light radiation into the universe in the distance, and exclaimed.

"Gargantua!"

Murphy on the side said.

Pang Xuelin nodded, and what appeared in front of them was a super-large black hole composed of the black hole itself, light, and accretion disk.

The darkest part in the middle is the shadow of the black hole, which is about twice the event horizon.

The thin outer circle of light is the black hole's circle of photons.

The huge accretion disk revolves around the black hole. The accretion disk is composed of various high-speed rotating, slowly falling matter and gas into the black hole, and becomes extremely bright due to strong collisions and radiation.

The accretion disk above the black hole appears larger and brighter than the one below it.

Pang Xuelin knows that the top of the black hole is actually the far end of the accretion disk, and the bottom is the bottom of the far end of the accretion disk. The gravitational field of the black hole distorts the propagation path of light, which forms such a strange phenomenon.

The space agency has sent probes to this world before, and finally concluded that the mass of this black hole is equivalent to 100 million times the mass of the sun.

Its horizon radius reaches 295 million kilometers.

You know, one astronomical unit, that is, the distance from the earth to the sun is almost 150 million kilometers, and the event horizon radius of this black hole is equivalent to two astronomical units, so imagine how huge this black hole is.

At least in Pang Xuelin's impression, the black hole of Galactic Sagittarius A is more than 40 million times the mass of the sun.

Only the black hole at the core of the Andromeda Nebula has such a volume and mass.

But the Gargantua in front of him is absolutely impossible to be the black hole in the Andromeda Nebula.

The reason is simple. On a clear night on the earth, in a place where light pollution is not serious, we can see a sky full of stars when we look up. Most of them are relatively close to the solar system. The closest star is Proxima Centauri, about 4.22 light years away. The Nanmen 2 binary star (a triple star system with Proxima Centauri) is about 4.37 light-years away, Barnard's Star is about 6 light-years away from us, and Sirius is about 8.7 light-years away from us. If the position of the center of the Milky Way is compared, it will be far behind.

If calculated by the number of stars per cubic light-year, there are only about 0.004 stars per cubic light-year in the vicinity of the sun. It is generally believed that the star density in globular clusters is relatively high, where the star density is about 2 per cubic light-year. stars, which is equivalent to 500 times the density of stars in the space near the sun.

But the density around the center of the galaxy is even higher than this. Astronomers observed that there are as many as 42 million stars distributed in the space of one parsec (3.26 light-years) in length, width and height at the center of the Milky Way, or the density of stars there is as high as There are 289,000 stars per cubic light-year, which is 72 million times denser than the density of stars in the vicinity of the solar system.

Under such a star density, if the earth is near the center of the galaxy, we can probably see millions of stars brighter than Sirius, and the brightness at night is similar to that of sunlight shining during the day.

If it is the Andromeda M31 black hole, it will be even more exaggerated.

But there was no such scene in front of him.

The Eternal Night spacecraft is at least 10 billion kilometers away from Gargantua. Pang Xuelin can clearly observe the sparse starry sky around Gargantua, which is far less dense than imagined.

Near Gargantua, the only thing that can be observed is a dark red planet the size of a ping pong ball in the distance and another main sequence star similar to the sun.

Together with Gargantua, these two stars form a three-star system.

But because Gargantua's mass is too large, these two stars move in circles around Gargantua like ordinary planets.

"Okay, everyone returns to their respective posts, releases the detection satellites, and conducts an all-round detection of our galaxy."

"clear!"

Following Pang Xuelin's order, everyone in the spacecraft has entered an unprecedented busy state, especially the visible light telescope and radio telescope carried by "Yongye", which has carried out a large-scale survey of Gargantua and the major nearby galaxies scale observations.

But the results of the observations surprised everyone.
