Is it the sun that revolves around the earth?

In this article, we will address a question that has sparked much debate over the centuries: does the sun revolve around the earth? To answer this question, we will discuss different aspects such as the historical origin of this idea, the scientific advances that have allowed it to be questioned, and the current consensus among professionals. Stay with us for a complete and detailed exploration of this fascinating subject!

1. The historical origin of geocentric theory

The idea that the sun revolves around the earth has its roots in antiquity, more precisely in the geocentric theory. The latter was born from the observation of the stars and the position of the earth in the universe, as it was perceived at the time.

Geocentrism in ancient thinkers

Ancient philosophers and astronomers, such as Ptolemy and Aristotle, held that the Earth was the center of the universe and that the other stars, including the Sun, revolved around it. This belief was reinforced by the fact that, from the Earth’s surface, the Sun appears to move from east to west every day.

The influence of religion

Many religions, especially those of the Book, have long supported the geocentric theory because it was in agreement with certain interpretations of sacred texts. For example, for Christians, it was difficult to conceive that God had created a world in which the earth did not occupy a central and privileged position. This worldview persisted for many centuries, until the appearance of the heliocentric theory.

2. Questioning the geocentric theory

Over time, new scientific observations and discoveries have led to a rethinking of the Earth’s position in the universe. This is how the opposite theory to the geocentric theory was born: the heliocentric theory.

The contributions of Nicolas Copernicus

At the beginning of the 16th century, the Polish astronomer Nicolaus Copernicus proposed a revolutionary theory: heliocentrism. According to him, it is the earth that revolves around the sun and not the other way around. This bold idea challenges the beliefs of the time and raises many debates. However, due to a lack of sufficient evidence, his theory struggles to convince contemporaries.

Galileo’s observations

In 1609, the Italian astronomer Galileo Galilei first observed the movements of the planets using a telescope. His discoveries, including the phases of Venus and the satellites of Jupiter, confirmed Copernicus’ heliocentric theory. Despite this, the Catholic Church, which supported the geocentric theory, condemned Galileo for heresy in 1633.

3. The current scientific consensus

Today, thanks to scientific and technical progress, the answer to the question of whether it is the sun that revolves around the earth is clear: it is a misconception, overtaken by the current consensus.

Advances in astronomy and physics

Since the work of Copernicus and Galileo, advances in astronomy and physics have allowed us to better understand the laws that govern the universe. The laws of universal gravitation, stated by Isaac Newton in 1687, notably confirmed that it is indeed the Earth that revolves around the Sun.

Satellite images and space missions

Satellite images and space missions conducted since the mid-20th century have definitively confirmed heliocentrism. Indeed, these missions have made it possible to directly visualize the position of the Earth to the Sun and to precisely measure the movements of the planets in our solar system.

4. Conclusion

To conclude, it is now indisputable that it is not the sun that revolves around the earth, but the other way around. The geocentric theory, which supported this idea, has been definitively refuted by scientific advances, notably thanks to the work of Copernicus, Galileo, and Newton. Thus, the initial question of this article can be answered with certainty: it is the earth that revolves around the sun, and not the other way around.
