Question

From the study of the universe, what can we say with certainty?

a) The planet earth is privileged, and the sun constantly rotates around it.
b) The sun is the vital factor, and all planets revolve around it, with Earth in a privileged position.
c) Lunar times determine day and night, correlating with different times of the year.
d) We cannot deduce anything absolute, as the sun is not vital, and other systems may exist.

Answer 1

The Sun is central to our solar system, with Earth and other planets revolving around it. This heliocentric model was proposed by Copernicus and is supported by physical laws like Newton's universal law of gravitation. Earth's rotation causes day and night, not celestial objects moving across the sky.

Step-by-step explanation:

From the study of the universe, we can say with certainty that the correct option is: b) The sun is the vital factor, and all planets revolve around it, with Earth in a privileged position. The Copernican model revolutionized our understanding of the cosmos by positioning the Sun at the center of the solar system, with planets, including Earth, revolving around it. This heliocentric view has been supported by a wealth of astronomical evidence, including the laws of physics such as Newton's universal law of gravitation. We now know that the Earth rotates on its axis every 24 hours, leading to the regular occurrence of day and night as different parts of the planet are exposed to or shaded from the Sun. This rotation gives the illusion of celestial objects moving across the sky, but in reality, it is Earth's rotation that gives rise to this observation.
