Strange Phenomenon of Black Holes

(P. S.: Please release the official version and add it to your favorites (ω))

Humanity has already achieved something remarkable by doing this. When the data was transmitted to Lyra by scientists, and when these results were seen by the scientific teams of the Star Alliance Member Civilizations, they were all extremely shocked.

Black holes! The most extreme celestial objects in the universe. Scientists from Star Alliance Member Civilizations never imagined they would one day see news of black hole exploration, yet here they are. Against the backdrop of such extreme celestial bodies as black holes, humanity's advanced materials technology has once again redefined their understanding.

However, this wasn't the end. After the third batch of Probe Spaceship completed their experimental mission, human scientists sent a fourth batch of Probe Spaceship towards the black hole. Well, the word "fourth batch" isn't entirely accurate, because this time there was only one Probe Spaceship.

This is Probe Spaceship that humanity invested heavily in to create after deciding to conduct preliminary explorations of this black hole.

The spaceship wasn't large, only about three kilometers in size, clearly belonging to the Lake-class spaceship category in terms of size. For its stability, humans designed its exterior with an eggshell-like structure, using only Strong Material, including the frame.

It is filled with various technological creations made using Gravity Potential Well Technology, the purpose of which is naturally to generate a corresponding gravitational field to protect the important instruments and equipment inside the Probe Spaceship.

It can be described as a Strong Material Probe Spaceship. The production process of Strong Material is very advanced, and it took humans a lot of time and resources to develop such a probe. It can be said that humans have really gone all out this time to scientifically explore black holes.

As expected, this meticulously crafted probe Probe Spaceship lived up to expectations. It successfully crossed the farthest distance ever created by mankind, surpassing the threshold of four times the Black Hole Radius, and its internal instruments continued to operate normally. This result brought a sigh of relief and excitement to the scientists.

"Hold on! Keep going! Keep going!"

Because the experiment was being broadcast live on a human network platform, everyone who was following the progress of the scientific experiment was silently praying.

As the meticulously crafted Probe Spaceship gets closer and closer to the black hole, everyone's hearts are pounding.

As civilization levels rise, humanity accumulates more and more scientific and technological knowledge. As a result, the time required for humans to learn and graduate has increased from fifty years to eighty years, and for those who need to pursue specialized and in-depth knowledge, it has reached a century.

There's no way around it; there are just too many Credits, and the required courses are increasing accordingly. Humanity attaches great importance to scientific development and even to science itself, so learning is naturally indispensable.

For this reason, the average person has a fairly good scientific literacy, so they know what it means to cross four times the Black Hole Radius: it means that human creations will be filling a region three times the Black Hole Radius.

Yes, that's not a trivial statement.

The so-called Three Times Black Hole Radius Orbit is actually the Innermost Stable Circular Orbit of the black hole. It is the innermost critical orbit in which a massive object can stably orbit around a black hole, and it is also the destination that the probes hope to reach in this human exploration of black holes.

Once it exceeds this orbit, anything with mass will lose its stable orbit and fall into the black hole at near the speed of light.

Black holes are so fascinating that no intelligent civilization can resist the temptation to explore them.

Amidst the intense anticipation and anxious attention of countless hearts, the Probe Spaceship, constructed from Strong Material, successfully reached the outer edge of Three Times Black Hole Radius Orbit after circling it several times. Its near-orbital distance from the calculated critical innermost stable orbit was only 1,700 kilometers away.

Yes, near orbit!

As scientists predicted, this black hole was formed by the merger of black holes created from the collapse of stars. Therefore, it is not a stationary black hole, but a rotating one. The difference between a rotating black hole and a stationary black hole is that a stationary black hole is spherically symmetric, while a rotating black hole is an axially symmetric ellipsoid.

Such a black hole would pull the surrounding spacetime to rotate with it. This kind of rotation is a rotation of the reference frame, which is very different from the phenomenon of orbiting. It has great research significance. Therefore, the orbit of human creations here is naturally elliptical, and thus there are near and far orbits.

A distance of over a thousand kilometers is practically face-to-face on an astronomical scale, so humanity cannot allow this Probe Spaceship to get any closer. If it goes any further, humanity will lose this Probe Spaceship, which has been the result of tremendous effort. This Probe Spaceship is not meant to crash, but to continuously observe black holes at close range, so it can be considered a success as it has already come this far.

The Probe Spaceship then aimed directly at the black hole for close-up observation, providing humanity with a completely new perspective on observing black holes, enriching our scientific database and refreshing our understanding of them.

Over time, the Probe Spaceship has provided humanity with a direct view of the Black Hole Photon Sphere.

Yes, Photon Sphere.

What appears on the human Holographic Screen is not a completely black hole, but a black hole whose surface is covered by a vast sphere of light. This is completely different from the black holes that humans usually see in online images. It is not a picture of a black hole with a ring of light on the outside, but rather a vast sphere of light without any blackness. However, the light sphere is clearly different from the light of a star; it appears very distorted, to the point that human probes can see themselves in their own lenses.

Of course, it cannot be seen all at once, but is the result of a long exposure, because too few photons enter the detector in a short time to form an image.

It is known that this phenomenon occurs when light hits the detector's surface, is diffusely reflected, is then distorted by the black hole, and circles back to the detector's optical receiving equipment.

As time went on, people discovered another amazing phenomenon: the time of the outer probes showed that no matter where the probes were in the black hole's orbit, they could see the silhouette of the probe Probe Spaceship that had almost reached the Innermost Stable Circular Orbit.

From the perspective of other peripheral Probe Spaceship, the Strong Material Probe Spaceship seemed to have suddenly multiplied into countless clones, scattered in every corner outside the Black Hole Photon Sphere.

The distortion of spacetime causes human senses to be misled.

Amid cheers, scientists began conducting experiments on the black hole using this detector, such as sending Photon Beam at it and observing it using various detection methods.

A series of observational experiments confirmed a previous theoretical solution regarding the Black Hole Photon Sphere, proving that the solution was correct.

This refers to the region within the black hole's Photon Sphere, which extends from the black hole's Schwarzschild Radius Orbit to the Schwarzschild Radius Surface, i. e., the Event Horizon of the black hole.

Here, massless particles like photons can run stably. Photons that come from all directions of the universe will be bent by the strong Gravity of the black hole. Many photons will turn and circle around here, eventually forming a shell of light. This is what a black hole looks like to humans on Holographic Screen.

However, because there are not many photons, this light shell appears very faint.

When human scientists shifted their perspective to the data feedback from Tachyon Detection, they witnessed an even more amazing scene.

From the perspective of Tachyon Detection, the radius of this black hole's "darkness" suddenly expanded by 1.5 times from the Schwarzschild Radius.

This phenomenon, in turn, verifies another related phenomenonal solution to the black hole theory: the Photon Sphere.
