DESCRIPTION:A free public lecture at 7pm sharp on Thursday\, December 5th a
 t the McIntyre Medical Building\, Room 522 by Prof. John Sievers from McGi
 ll University.\n	\n	From high in the Chilean Andes to the South Pole to spac
 e satellites to balloons over Antarctica\, astronomers are searching for f
 aint echoes from the big bang. These echoes (called the cosmic microwave b
 ackground or CMB) come from when the universe was just 400\,000 years old\
 , long before any stars or galaxies had formed. By studying the CMB in det
 ail\, we have transformed our understanding of the cosmos\, and we now hav
 e precise measurements of how old the universe is\, and what it is made up
  of (including an unambiguous signature of dark matter). I will explain wh
 ere the CMB comes from\, how we study it\, and some of what we have learne
 d from it.\n
