Voyage of the Stars.

Chapter 1613 The World in the Painting
Like the three-dimensional universe, the two-dimensional world is almost flat on a small scale, but on a wide scale, this two-dimensional world is also curved, like a large carpet with some undulations.

Of course, this phenomenon cannot be seen from a two-dimensional perspective because its undulation direction is the third dimension. However, this statement is also inaccurate because this two-dimensional world does not have a three-dimensional macroscopic existence. Therefore, it should be said that it is curved on the cosmic membrane.

This was a scenario the Great Voyage Organization had never encountered before, since the two-dimensional worlds they had encountered in the past were all very small, far from reaching the large scale where spacetime curvature occurred.

Because it takes place in a two-dimensional world, the current observation method of the Great Voyage Organization is not the usual optical observation, but cosmic membrane detection.

A cosmic-level civilization has this capability.

As for optics, light also exists in the two-dimensional world, but it does not exhibit wave-particle duality here; instead, it only has wave properties.

Light waves also have amplitudes, and different amplitudes and frequencies contain different energies, representing different types of light. The movement of light waves constitutes light rays.

This phenomenon of light is merely an appearance in the two-dimensional world because it actually has duality, but its particle properties have been hidden, hidden in the microscopic world.

This is easy to understand.

The microscopic world in the three-dimensional world has six microscopic dimensions, so the two-dimensional world has one more microscopic dimension, making it seven microscopic dimensions. After all, the essence of dimensional reduction is to curl up the macroscopic dimensions into the microscopic, which is also why four-dimensional life forms can easily enter it.

It turns out that stars do exist in this two-dimensional world. They may have been formed by flattening planets from the original three-dimensional world, or they may have evolved from the two-dimensional world itself.

The two-dimensional planet formed by flattening a three-dimensional planet has been studied by several civilizations of the Great Voyage Organization. There is nothing special about it, and there is not much value in repeating the study. Therefore, after detecting that it was the former, the Great Voyage Organization did not pay much attention to it and sailed past it, heading deeper into the two-dimensional world.

The Great Voyage Organization is looking for stars that have evolved on their own.

That was something no one had ever seen before, and it was the object of research value that everyone had been looking forward to seeing during this cross-two-dimensional journey.

This two-dimensional world is obviously decades or even billions of years old. After all, its vastness is what it is. If we don't consider the expansion of the universe, then it is at least seven billion to ten billion years old. Even if we take the expansion of the universe into account, it is no less than five billion years old.

Such a long period of time is almost enough for stars to form, and it's not impossible that life might even exist there, since Earth is not the template for the birthplace of all life in the universe.

During the long voyage back then, everyone had seen all kinds of life forms, including carbon-based life, silicon-based life, and sulfur-based life. Their birth environments were different, and their evolution times were also vastly different.

In fact, even among the same type of carbon-based life, the time it takes for them to evolve from birth to intelligence varies greatly.

Therefore, it is indeed possible that life exists in a two-dimensional world.

However, we have only just entered the two-dimensional world and our exploration scope is still limited, which may be why we haven't discovered anything yet.

As the Great Voyage continues to expand, all sorts of scenery comes into view.

After traveling approximately eight million light-years, the Great Expeditionary Force detected numerous two-dimensional planets. The first things they saw were almost all stars, as these were the light sources and the easiest to spot. From a two-dimensional perspective, these stars appeared as long, thin strips of light. From a three-dimensional perspective, they were, of course, circular, and their interiors and exteriors were clearly visible. They could see that as the temperature changed, the two-dimensional stars exhibited different colored ring structures from the inside out, much like lollipops.

However, they cannot be seen from a two-dimensional perspective. From a two-dimensional perspective, they can only be seen as long strip lights emitting light waves and illuminating the two-dimensional world.

Because gravity in the two-dimensional world follows an inverse first-power law, its intensity is much greater than in the three-dimensional world, making planets appear much smaller.

This does not conflict with the idea that unfolding a three-dimensional object into a two-dimensional surface results in a huge two-dimensional surface, because one is an unfolding of dimensions, while the other is an object that originally belonged to two dimensions.

Gravity in a two-dimensional world is quite interesting. It is directly proportional to the radius of a planet, which is the same as the square root of the planet's surface area, and inversely proportional to the distance between two planets.

Under these rules, there are also two-dimensional planets that revolve around stars according to different rules.

Unfortunately, this galaxy was also the result of a three-dimensional object being flattened and then evolved. The Great Voyage Organization only took a brief look at it, admiring its picturesque beauty, before continuing on its way.

The world depicted in this painting is vast. Fortunately, the members of the Great Voyage Organization are now at the cosmic level. Although their warp speed is not yet that high, they do not need to use traditional warp speed travel in the two-dimensional world. Instead, they use high-dimensional jump technology.

After all, everyone is a higher-dimensional being in this two-dimensional world, not to mention the Galactic Center Civilization, which is proficient in three-dimensional jumping technology.

This allowed the entire Great Voyage Organization to easily leap and travel in the two-dimensional world. If warp drive in the two-dimensional world is like a car speeding on the road, then the Great Voyage Organization is now like flying an airplane in the sky, leaving only shadows on the ground.

That is the projection of a higher-dimensional object onto a lower-dimensional object.

If life in this world were observing this universe, and they happened to be looking towards the area where the Great Voyage Organization was passing by, they might see the once bright world now obscured by shadows, and they would certainly be curious about what could be blocking the light of such great stars.

Unfortunately, the Great Voyage Organization has not yet discovered any two-dimensional life forms.

Moreover, perhaps because the Great Voyage Organization is still on the outskirts of the two-dimensional world, the planets they see are basically the same planets that were flattened in the original three-dimensional world. Some of these planets were even found to have gravitational fluctuations in their vicinity because they hadn't been flattened long enough.

The gravitational fluctuations were so strong that they could even cause the entire two-dimensional flat world of the region to warp and curl up, just like the waves on the sea.

Seeing this situation, the Great Voyage Organization finally understood how the undulations of the two-dimensional world were formed. It was the transmission and interaction of these gravitational disturbances that acted on the cosmic membrane, thus forming undulating regions like a mountain-carving motion.

From a higher-dimensional perspective, this world is like a painting with a slightly curved and wrinkled surface, in which planets are clearly visible, as mesmerizing as Van Gogh's Starry Night. However, upon closer inspection, one can see the exquisite details.

It can be described as a world within a painting.

"It's so beautiful, but a little monotonous!"
