Canberra, Oct 26: Scientists have come up with an answer to the puzzling question of why life on Earth coincides with a momentous shift in the makeup of the universe.
According to a report by ABC News, research into finding an answer to this mystery was done by Ph. D. student Chas Egan and Charley Lineweaver from Australian National University.
The conundrum has its roots in the way the universe changes as it expands, explained Egan.
Soon after the Big Bang, some 14 billion years ago, most of the energy in the universe was in the form of heat. Later, as the universe cooled and expanded, matter, such as stars and planets, became dominant.
