Once upon a time, there was a great scientist on Earth named Galileo. Not only did he change our understanding of the world, but he also created a new perspective – the "sun-centric cosmology."
In our lives, we all know that the moon revolves around the earth. In ancient times, people believed that this was the case, and based on it, they established their astronomical theories and observation systems.
However, when we look at this from a higher perspective, we see that things may not be so simple. Because, on the other hand, if we assume that the earth revolves around the sun, then many of the problems can be explained very well.
We can observe that the changes in the four seasons of the year are not caused by the rotation of the earth. In fact, this change is caused by the rotation of the Earth around the Sun. And if we look at the moon, you'll be surprised to find that it actually orbits the Earth!
Through the telescope, we can see that other planets are also moving in a similar direction. This coincides with what is commonly thought of as heliocentrism, which states that all celestial bodies revolve around the sun.
Despite this evidence to support heliocentrism, most people at the time were still unable to accept the notion. They thought it was a crazy idea, and some people even went to jail for it.
It wasn't until hundreds of years later, when Newton proposed the law of universal gravitation, that people slowly began to accept this fact. Now, the "heliocentric cosmology" has become one of the widely accepted views in the scientific community.
Galileo's "heliocentric view of the universe", although it was once questioned and opposed, actually provides us with a new worldview that gives us a deeper understanding of how nature works. In the process, we have also seen the importance of the continuous progress and development of human knowledge, as well as our determination to make unremitting efforts on the path of searching for the truth.
