QUESTION 14

❄Edwin Hubble made many important contributions to astronomy. Up until his observations in 1922, scientists were of the opinion that the universe consisted of only one galaxy: the Milky Way. Hubble's observations of Cepheids and subsequent measurement of their distances (using Henrietta Swan Leavitt's calculations) showed that many celestial objects were too far away to be part of the Milky Way and were actually galaxies themselves.❄

❄By calculating the distances to many newly found galaxies, Hubble also discovered that the galaxies were receding away from Earth and that the speed of recession was proportional to the distance. This established the fact that the universe was expanding, which changed the entire consensus (from the time of Newton) that the universe was finite. It also backed up Georges Lemaître's theory that the universe had a beginning (later called the Big Bang).❄
