SUMMARY:Measuring the Universe with a 10^26 inch ruler - Prof Alan Heavens
 \, Astrophysics Group\, Imperial College London
DTSTART:20150303T193000Z
DTEND:20150303T203000Z
UID:TALK57502@talks.cam.ac.uk
CONTACT:Stanislav Fort
DESCRIPTION:By making precise measurements of the geometry of the Universe
  we can learn some remarkable things\, such as whether it is curved or not
 \, what the nature of Dark Energy is\, whether we live in extra dimensions
 \, and whether there are new species of fundamental particles that have no
 t yet been discovered on Earth.  To help\, we use a key observable quantit
 y - the Baryon Acoustic Oscillation (BAO) scale\, which is the distance so
 und waves travelled in the early Universe.  These sound waves leave their 
 imprint in the clustering of galaxies today\, and the ‘sound horizon’ 
 acts as a cosmic ruler that can be used to measure the Universe and tell u
 s about the physics driving the acceleration of the Universe now\, and pos
 sible new physics in the first million years after the Big Bang.
