![]() The Big Bang theory was first proposed by Alexander Friedmann in 1922, and Hubble’s observations in the late 1920s provided the first observational support for the theory. This became known as the Big Bang theory, and today is accepted by the vast majority of physicists. Edwin Hubble was born in Missouri in 1889, the son of an insurance executive, and moved to Chicago nine years later. In 1929 he showed that galaxies are moving away from us with a speed proportional to their. This implied that at some point in the distant past, approximately 14 billion years ago, the universe started off as a point of extreme density and temperature. Edwin Hubble was a man who changed our view of the Universe. The further apart the galaxies, the faster they diverged, and the redder the light was. ![]() This was interpreted by cosmologists as meaning that the universe was expanding outwards in all directions, and that the redshift represented a Doppler effect whereby light from distant galaxies was stretched out as the intervening space expanded. Edwin Powell Hubble, nado o 20 de novembro de 1889 en Marshfield ( Missouri) e finado en San Marino, California o 28 de setembro de 1953 en California, foi un astrónomo estadounidense. In 1929, along with Milton Humason, Hubble measured the distances and redshifts of 46 galaxies, establishing an empirical correlation between the distance of these objects and their redshifts. Hubble’s second great “discovery” is not really his own, although he is often incorrectly credited for it. Desde el Observatorio Mount Wilson, Hubble observó objetos mucho más grandes y distantes que la Vía Láctea, que hasta entonces no se habían observado. Edwin Hubble began his career by working at an observatory. From his mountain perch high above Los Angeles, Hubble set his sights on fuzzy clouds of cosmic light called nebulas-and hit the jackpot. Edwin Hubble avanzó nuestra comprensión del universo y cambió las opiniones predominantes de la cosmología.
