2012 Dirac Lecture: The Accelerating Universe - presented by Professor Brian P. Schmidt

Published on Aug 10, 2012

The UNSW Science 2012 Dirac Lecture was presented by Nobel Laureate Professor Brian P Schmidt.
The Accelerating Universe: In 1998 two teams traced back the expansion of the universe over billions of years and discovered that it was accelerating, a startling discovery that suggests that more than 70% of the cosmos is contained in a previously unknown form of matter, called Dark Energy. The 2011 Nobel Laureate for Physics, 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.

.. not sure if it's the one on tv now, i've learned one thing though .. he just said "we use 'dark' for something we really don't understand" .. hmm, a thought
just while typing that was it could apply to the lack of understanding of racists, too .. course those woans of 'man' do understand that .. yup, woans do
know racists exist in their own tiny, diminished and 'fixed' universe .. sod, so easy it is to slip from light to dark .. oh, he just finished .. me too .. grin ..
