The expanding cosmos

1 Comment / Astrophysics / By

ABSTRACT For centuries, mankind’s understanding of the universe was mainly informed through religious beliefs. It was not until the 20th century, when Einstein published his paper on General relativity, in 1917, that humanity began to understand the nature of the universe in scientific terms. Einstein’s work not only formed the backbone of physical cosmology …
