No, it is not true that the Sun is revolving around the Earth. The heliocentric model, which places the Sun at the center of the solar system, is the accepted scientific understanding. The Earth, along with other planets, revolves around the Sun in elliptical orbits.
The geocentric model, which proposed that the Earth was the center of the universe and that all celestial bodies revolved around it, was the prevailing belief for many centuries. However, in the 16th and 17th centuries, astronomers such as Nicolaus Copernicus, Johannes Kepler, and Galileo Galilei provided compelling evidence for the heliocentric model.
Observations and experiments, such as planetary motion and the phases of Venus, revealed that a heliocentric model offered a more accurate explanation of celestial phenomena. These discoveries eventually led to the widespread acceptance of the heliocentric model, which is supported by a vast amount of evidence and is the foundation of modern astronomy.
Therefore, according to our current understanding of the solar system, the Earth orbits the Sun, not the other way around.
