DESCRIPTION:Modern fundamental physics contains ideas that may radically c
 hange our understanding of the world\; ideas such as extra dimensions of s
 pace\, or the possible existence of other Universes. Testing these concept
 s requires enormous energies\, far higher than what is achievable by the L
 arge Hadron Collider at CERN\, and in fact\, beyond any conceivable Earth-
 bound experiments. However\, at the Big Bang\, the Universe itself perform
 ed the ultimate experiment and left clues and evidence about what was behi
 nd the origin of the cosmos as we know it\, and how it is evolving. In the
  past decade we have been able to answer age-old questions accurately\, su
 ch as how old the Universe is\, what it contains\, and its destiny. Along 
 with these answers have also come many exciting new questions. I will pres
 ent an overview of current cosmological constraints from the cosmic microw
 ave background and large galaxy surveys\, and comment on some of the exper
 imental and methodological innovations that are needed to realise the prom
 ise of upcoming surveys.
