Regarding this question, I can give you a simple and crude answer. The position of the earth is probably above and below the third ring of the Milky Way and the solar system. Although this position is not 100% accurate, according to what I know information, the gap will not be too big. Around the 20th century, scientists had already given different observations and concepts about nebulae and the universe. Our current Milky Way is actually just one of billions of galaxies in the expanding universe, because in the 21st century, because With the improvement of our science and technology, we humans have been able to observe the overall structure of the universe, and in the process of observation, it has begun to become more and more clear.

According to the analysis of scientists, the super-galactic cluster has formed a huge network structure containing a large number of fibers and gaps. This kind of super-galactic cluster may have large-scale fiber structures or holes, and it is more likely that It is the largest coherent structure in the universe. When we understand the earth, we must know the latitude and longitude of our country, because in terms of latitude, our country is approximately located in the northern hemisphere north of the equator, and our country’s latitude is approximately close to 50 degrees. The longest straight-line distance is probably about 5,500 kilometers.

Because if when the northeastern region still appears larger, or more than a billionth of a second, the universe must be uniform, which means that all its parts have the same density on average, and In terms of composition and structure, our earth seems to be composed of about 75% water and 25% land. But in fact, if we cut the earth in half, we may find that the composition of this earth is very complicated. .

Because the core is actually the solid core in the center, and the solid core is the core of the earth. If the core is very small, it will be about 2556 kilometers, so it is one-fifth of the diameter of the earth, because everyone knows, The universe actually has no center or boundaries, so we cannot mark the absolute position of the Earth in the entire universe. However, the Earth is located at the center of the observable universe, because observability actually depends on the distance from our Earth.
