What was the center of the universe discovered by Copernicus?

It is life and death.

One day, Copernicus suddenly discovered that the sun rose and set differently every day, so he kept his pants open and observed where the sun rose and set every day. After a year of observation, he found that on the first day of the year, the sun rises and sets and returns to square one.

Copernicus then concluded that the geocentric theory that the teacher spoke about was wrong, that it was not the sun that revolves around the earth, but that the earth revolves around the sun. This inference can be proved by scientific experiments and is logical, so Copernicus considered his judgment to be absolutely correct. Copernicus was delighted to know that this was a major discovery, and soon wrote "The Theory of the Center of the Sun".

Nicolaus Copernicus was a Polish astronomer who proposed heliocentrism in the 16th century, a theory that changed people's perceptions of the universe. Copernicus was not the first person to discover that the earth was round, in fact, ancient Greek philosophers and astronomers had already put forward the idea that the earth was round as early as BC. For example, the ancient Greek philosophers of the 5th century BC, Pythagoras, Plato, and Aristotle all believed that the earth was round.

Copernicus was able to discover that the earth was round, mainly because of his research in astronomy. He observed astronomical phenomena, such as the shape of the Earth's shadow projected on the Moon (when the Earth is between the Sun and the Moon, the Earth's shadow falls on the Moon, forming a lunar eclipse), as well as the laws of star and planetary motion. These observations led him to the conclusion:

The Earth is not the center of the universe, but a planet that orbits the Sun, and the Earth is round.

But in fact, Copernicus's contribution was not to discover that the earth was round, but to overthrow geocentrism and put forward heliocentrism. Geocentrism holds that the Earth is the center of the universe and that all celestial bodies, including the Sun, revolve around the Earth. Copernicus's heliocentric theory, on the other hand, held that the sun was at the center of the universe and that the earth and other planets moved around the sun.

This theory was not immediately widely accepted at the time, but in later centuries, heliocentrism gradually became the dominant view, laying the foundation for the development of modern astronomy and science.

Copernicus' "heliocentric theory" is the idea that the sun is the center of the universe.

Because the relationship between the five planets of the solar system and the sun was not known at the time, Copernicus believed that the sun was the central body of the universe. Therefore, compared with Ptolemy's geocentric theory, Copernicus's heliocentric theory is a great improvement, but its limitations cannot be ignored.

Copernicus's theory brought great changes to the human view of the universe, and he moved the center of the reference frame for scientific understanding of the movement of celestial bodies from the earth to the sun, thus taking the most difficult and important step in modern cosmological research. For thousands of years, people have been accustomed to seeing the sun, moon and stars rise in the east and set in the west, and Ptolemy's explanation is in line with common sense. But Copernicus's deep contemplation of this seemingly truthful common sense tells us that common sense can also be wrong.

Science is not the same as common sense. It is possible to discover the truth of science by taking a curious glance at what we are accustomed to and by analyzing it scientifically.

What kind of scientific revolution did Copernicus set off?
