In 1929, Edwin Hubble discovered that the universe was expanding, and the velocity of expansion was a function of the distance from the Earth. Until 1998, most physicists and cosmologists believed that the expansion would eventually be reversed by gravity resulting in a “Big Crunch.” In 1998, three physicists (Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess) decided to measure the expansion and expected to confirm that it was slowing down. To their surprise, and the scientific community’s surprise, they discovered that the universe’s expansion was accelerating. This scientific discovery has puzzled scientists ever since. In this four part series, physicist Louis Del Monte discusses the discovery history and proposes a new theory to explain it. This theory is also fully explained in Louis Del Monte’s new book, Unraveling the Universe’s Mysteries (available in paper back or as an eBook on Amazon and Barnes & Noble
