The accelerating Universe: Nobel Laureate Brian Schmidt
The accelerating Universe: Nobel Laureate Brian Schmidt
Δημοσιεύτηκε στις 2 Αυγ 2012
In
1998 two teams traced back the expansion of the universe over billions
of years and discovered that it was accelerating. It was a startling
discovery that suggests that more than 70 per cent of the cosmos is
contained in a previously unknown form of matter, called Dark Energy.
In
this video, Brian Schmidt, leader of the High-Redshift Supernova Search
Team, describes this discovery and explains how astronomers have used
observations to trace our universe's history back more than 13 billion
years, leading them to ponder the ultimate fate of the cosmos.
Brian's
work on the accelerating universe was awarded the 2011 Nobel Prize in
Physics, jointly with Adam Riess and Saul Perlmutter.
