Reference Material:
For thousands of years, philosophers and astronomers and thinkers of all sorts have imagined that the universe, the space around us was rather like this floor in front of us. It was fixed and unchangeable and thins happen on it, just as people walk around. So the stars, the comets, and the planets, and the other heavenly bodies moved around and traced down their parts on this completely unchanging stage of space. In the 20th century, as the result of Einstein’s work that view of the universe was completely transformed. We began to understand that there was no absolutely fixed stage of space at all on which all celestial notions were played out. But in some sense on the larger scale in the universe, the space itself was in the state of a continuous dynamic change. That was a prediction made by Einstein.But it wasn’t Einstein Harold the owner of making the discovery that our universe was really like that.
Sample Answer:
For thousands of years, people believe that the world was like a flat floor and the universe was fixed and unchangeable. This view was transformed by Einstein in the 20th century who suggested that the universe is under continuously dynamic change all the time. However, Einstein was not the fist person who proposed this relativity theory, but Edwin Hubble who is an astronomer. (63 words)
