He believed the sun is the center of the universe and the earth and other planets went around it.Skim the text and draw the two theories of theuniverse with the following pictures.SunearthBefore Copernicus theory Showing Copernicus theoryReading and drawingSunearthBefore Copernicus theory Showing Copernicus theorySunearthearthSun Showing Copernicus theory A diagram showing the solar system with the earth at its centre A diagram showing the solar system with the sun at its centre BEFORE COPERNICUS THEORY Read the text carefully, then answer these questionsCareful readingBecause the powerful Christian Church would have punished him for even suggesting such an idea2. What was his theory about? (Para 1) All his mathematical calculations led to the same conclusion: that the earth was not the centre of the solar system. Only if you put the sun there did the movements of the other planets in the sky make sense.1. Why could he not tell about his theory? (Para 1)3. What had the astronomers noticed in the sky? (Para 2) They had noticed that some planets in the sky seemed to stop, move backward and then go forward in a loop. Others appeared brighter at times and less bright at others.4. When did Copernicus complete his theory? (Para 3)Between 1510 and 1514 he worked on it, gradually improving his theory until he felt it was complete. 5. How did he explain changes in the movement of the planets and in the brightness of the stars? When did he publish his idea? (Para 4) He placed a fixed sun at the centre of the solar system with the planets going round it and only the moon still going round the earth. He also suggested that the earth was spinning as it went round it and this explain changes in the movement of the planets and in the brightness of the stars. He published his idea as he lay dying in 1543. 6. Why do people think that there is a direct link between his ideas and the work of Isaac Newton, Albert Einstein and Stephen Hawking? Because his theory is now the base on which all our ideas of the universe are built. His theory replaced the Christian idea of gravity which said things fell to earth because God created the earth as the centre of the universe, He showed this was obviously wrong.Fill in the blanks with some proper words Copernicus was _ because he found the earth was not the centre of the solar _, only if you put the sun there did the _ of the other planets in the sky _ He kept improving his new theory until he felt it was _ in 1514. He Suggested that the earth was _ as it went round the sun .
