SUMMARY:Do the laws of nature vary across the universe? - John Webb (UNSW)

DESCRIPTION:Searching for space-time variations in fundamental constants p
 rovides an important test of grand unification theories.  Recent quasar me
 asurements hint at a possible spatial dependence of the fine structure con
 stant over cosmological distance scales. I will discuss the current status
  of this and describe how we aim to make the first 1000 measurements of va
 rying alpha at high redshift.  Such a large survey is made possible by the
  application of Artificial Intelligence methods for automated spectral ana
 lysis\, that also reduce systematics\, and remove any possible human bias 
 in the results.
