This article is a review about how distant supernovae are used as standard candles, enabling us to measure the history of cosmic expansion. This time of rebirth (in French, renaissance) in astronomy was embodied in the work of Copernicus (Figure 2.16). Countless forms of media have tackled this question, in fact the two highest grossing movies of all time, Avengers: Endgame (2019), and Avatar (2009) respectively have a strong focus on alien life.

He was the first to suggest that the movement of the planets, sun, moon, and stars could be equated in numbers. After Galileos work, it became increasingly difficult to deny the Copernican view, and Earth was slowly dethroned from its central position in the universe and given its rightful place as one of the planets attending the Sun. It begins as soon as we look up at night. With the eccentric circle the center of the planets orbit would not be Earth but would instead be some other point. The Babylonians were very advanced astronomers for their day because they had a system of writing so they could record.

Mammoth A-Z compilation of the ancient knowledge of a wide range of cultures. Its rays strike different parts of Earth along diverging paths. He also reasoned that the apparent rotation of the celestial sphere could be explained by assuming that Earth rotates while the celestial sphere is stationary. According to Copernicus developed a heliocentric plan of the solar system. The greatest influence on western astronomy comes from ancient Greece. With his theory, he was able to explain the complex retrograde motions of the planets without epicycles and to work out a roughly correct scale for the solar system. as they spun off from the Sun.
