the center of the universeThere were many views regarding the center of the universe. According to the traditional view, if the space of the universe was considered to be limited, then there should be a center. However, since the space of the universe was considered to be infinite, it was generally believed that the universe did not have a center. However, with the development of physics, the unified field theory believed that the infinite universe had a center. The theory believed that the center of the universe was the worker's own body. From this point of view, the position of the person was the center of the universe. In the online culture, Cao County in Shandong was ridiculed as the "center of the universe". In Shandong, there was also a view that all ten directions in the universe were infinitely far away, and all ten directions were equal to the center of the universe. In addition, Korea had the Luo Lao Space Center, but it was a space launch site and not the actual center of the universe. There were also some interesting debates, such as Henan claiming that it was the center of China's central region, but it was more qualified to claim that it was the center of the Earth, and Antarctica claimed that it was the center of gravity. These were more interesting concepts.

At the center of the universeCurrently, there were many opinions regarding the center of the universe:
** 1. The central position based on the Big Bang theory and related speculations **
1. ** Geometrie Center **
- Assuming that the Big Bang theory was correct, the energy was spread out in a spherical state during the Big Bang. However, due to the gravitational force between matter, the distribution of matter in the universe became complicated. However, the overall shape might still be spherical (just uneven).
- The Milky Way has been in operation for about 13.4 billion years and was formed 400 million years after the Big Bang. If the region during the Big Bang was regarded as the geometric center, the Milky Way was formed at the edge of this geometric center. The Milky Way revolved around the center of mass of the Virgo Supercluster at a speed of about 3.6 million kilometers per hour. According to this speed, the Milky Way had revolved about 45 million light-years in 13.4 billion years. Adding some assumptions, it had revolved about 500 million light-years. At the same time, considering the expansion of the universe, the Milky Way was formed 400 million years after the Big Bang. Assuming that the early Milky Way was in the middle of the universe's radius, its expansion speed relative to the center of the universe was 1.6 light years per year. It was calculated to be 21.4 billion light years away. Therefore, the Milky Way was about 21.9 billion light years away from the center of the universe (22 billion light years), which meant that the geometric center of the universe was 22 billion light years away from the Milky Way.
2. ** Quality Center **
- The Solar System was located in the Milky Way, which belonged to the Local Galaxy Group. The Local Galaxy Group revolved around the center of mass of the Virgo Supercluster, and the Virgo Supercluster revolved around the center of mass of the Lanyakea Supercluster. The center of mass of the Laniaea Supercluster was a giant source in the constellation Hydra, but it was not the center of mass of the universe. According to the size of the supercluster, there might be hundreds of superclusters that were the size of Laniakaiya revolving around the same center of mass, which was most likely the center of mass of the universe. According to the ratio of the solar system to the center of the Milky Way, the Milky Way to the center of mass of the Virgo Supercluster, and the Virgo Supercluster to the center of mass of the Lanikaia Supercluster, the center of mass of the universe was about 25 billion light-years away from the Lanikaia Supercluster, which was about the same as the calculated geometric center of the universe was about 22 billion light-years away from the Milky Way.
** 2. View based on the shape of the universe and the principles of modern physics **
1. ** No Center View Under the Flat Space Hypothesis **
- According to the measurement of the size of the hot spot angle in the microwave background radiation, the curvature of the observable universe is 0, which is a flat space. One possibility was that the space of the entire universe was flat. If the observable universe was only a small part of the entire infinite universe, an infinite universe without a center.
2. ** No Center Point of View Under the Hypothesis of Closed Spheric Space **
- Although the observable universe was flat, the entire universe might be a closed spherical space. Its volume had boundaries but no edges. It was a self-circulating three-dimensional space. Just like walking on the surface of the Earth, one could not find the boundary or the center.
3. ** Hidden central point of view under the hypothesis of high-dimensional space **
- The universe might be the surface of a four-dimensional supersphere. Because humans were missing a dimension, just like how creatures living on the surface of the earth could not find the center of the earth, humans could not find the center of the universe. However, the high-dimensional space was only a guess.
4. ** A non-central perspective based on the principles of Cosmology **
- On a large scale, the universe had a uniform distribution of matter. This was the principle of cosmos. Edwin Hubble observed that distant galaxies were moving away from us, and the farther away they were, the faster they moved. It looked like the Milky Way was the center of the universe, but because of the uniform expansion of space, no matter which galaxy observed the universe, it would see a similar universe with a radius of 46 billion light years. Therefore, it could only be assumed that the universe had no center.

Is the Dune universe the largest fictional universe?It's not straightforward to determine. The concept of 'largest' for a fictional universe depends on various factors like the breadth of the world-building, the number of story arcs, and the depth of the lore. So, it's difficult to claim that the Dune universe is the largest without a detailed and comprehensive comparison with others.
Longhua, the center of the universeIf "Longhua, the center of the universe" is a joke, according to the information provided, Longhua District has a unique geographical location in the city of Shen Zhen. It is located in the geographical and geometric center of Shen Zhen and the central axis of urban development in the Greater Bay Area of Guangdong, Hong Kong and Macau. It is adjacent to six districts and one city. It has convenient transportation and many development achievements, such as convenient subway lines (Line 4, etc.) and developed commercial centers.(such as Longhua Dalang Commercial Center), rich tourist attractions (such as Guanlan Ancient Ruins, Longhua Park, etc.), as well as various special areas (such as the cultural area represented by Shangwei Art Village), etc. However, if one were to take the literal meaning of "the center of the universe", there was currently no data to show that Longhua had a special central meaning in the universe. This might just be an exaggeration to express that Longhua was more important, diverse, and full of vitality in the local area.

I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain. Frank Herbert, Dune (Dune Chronicles, #1)
