Is it true that "the sun going around Earth and the Earth going around the sun are just two observations. None is better than the other. "?Vanadium 50 said:What mystery? As far as I can tell, science says something, and someone anti-science says something else. One is wrong. Why is this a mystery?
There are several pieces of evidence that support the fact that the Earth revolves around the Sun. One of the most notable is the observation of the phases of Venus, which can only be explained by its orbit around the Sun. Additionally, the changing positions of stars in the night sky throughout the year also indicate that the Earth is moving around the Sun.
The Earth takes approximately 365.24 days to complete one revolution around the Sun. This is why we have leap years every four years to account for the extra time and keep our calendars aligned with the Earth's orbit.
Yes, the Earth's distance from the Sun does change during its orbit. The Earth follows an elliptical orbit, meaning it is closer to the Sun at some points and farther away at others. This distance does not significantly affect the Earth's climate, as the tilt of the Earth's axis is the primary factor in seasonal changes.
The Earth's orbit around the Sun does not directly affect the length of a day. The Earth's rotation on its axis is what determines the length of a day. However, the tilt of the Earth's axis does change throughout the year, causing the amount of daylight hours to vary.
No, the Sun is not the center of the universe. The Sun is just one of billions of stars in our galaxy, the Milky Way. And the Milky Way is just one of billions of galaxies in the observable universe. Therefore, the Sun is not the center of the universe, but it is the center of our solar system.
