Scientific research shows that the
universe has been expanding at an accelerating rate; this is said to be due to the
dark energy that makes up some 70 percent of the total energy density of today's universe. This discovery further bears out the
big bang theory, which had been first proposed by astrophysicist and cosmologist
Georges Lemaître in 1927. LeMaître, who was born on this date in 1894, stated that the universe began some 20 billion years ago with the violent explosion of a small mass of matter at extremely high density and temperature.
Quote
"A universe that came from nothing in the big bang will disappear into nothing at the big crunch. Its glorious few zillion years of existence not even a memory." —
