GENERAL KNOWLEDGE

Detailed explanation-1: -Hubble’s brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving away faster. In other words, the universe must be expanding. He announced his finding in 1929.

Detailed explanation-2: -By 1929, Hubble had completely reimagined our place in the universe; not only was it home to millions of other galaxies, but the universe itself was expanding as well. Contrary to the previously held view of a static universe, Hubble ultimately proved that galaxies are, in fact, moving away from us.

Detailed explanation-3: -Hubble’s Law basically states that the greater the distance of a galaxy from ours, the faster it recedes. It was proof that the Universe is expanding. It was also the first observational support for a new theory on the origin of the Universe proposed by Georges Lemaitre: the Big Bang.

Detailed explanation-4: -Edwin Powell Hubble is renowned for determining that there are other galaxies in the Universe beyond the Milky Way, and for observing that the universe is expanding at a constant rate.
