The ancient Greek philosopher was executed for understanding the Moon

Greek philosopher Anaxagoras is one of the historical celebrities. His name is given to the crater near the North Pole of the Moon.

Living about 2,500 years ago, the philosopher Anaxagoras spent much time and energy observing and studying the mystery of the universe and astronomy. Among the issues that Anaxagoras cares about is the Moon. He observed the Moon for a long time and made some observations.

The philosopher Anaxagoras said that the moon was a rock, not a god of power.

According to Anaxagoras, the Moon is not much different from Earth. He believed that the Moon was a stone, not a powerful god that Greek people at that time believed.

Anaxagoras even believes that there are mountains on the Moon's surface. The philosopher Anaxagoras said that the moon is bright at night because it is reflected by the sun.

Anaxagoras also explained that the phenomenon of the Moon is sometimes "pitch black" because the Moon, Sun and Earth are lined up. At that time, the Moon was behind Earth's shadow and was known as a lunar eclipse . The philosopher Anaxagoras mentioned that the Moon, Sun and Earth are aligned, in which the Moon is in the middle, the sky will be dark during the day. Science today called the eclipse phenomenon .

With views contrary to religion and the opinion of the ancient Greek authorities at the time about the Moon and other issues, Anaxagoras was arrested, put on trial and sentenced to death.
