SUMMARY:Cosmic Past\, Present\, Future: Planck and Beyond\, Physics De
 partment Colloquium\, Benjamin Wandelt\, Paris Institute for Astrophys
 ics (IAP) at the Université Pierre et Marie Curie\, Sorbonne Univer
 sity
DESCRIPTION:How can we learn what banged at the Big Bang? We use astro
 nomical observations to probe the epoch in the very early Universe whe
 re quantum fluctuations imprinted the seeds of cosmic structure. I wil
 l summarize the main results of the analysis of the cosmic microwave b
 ackground temperature anisotropies as seen by the Planck mission data 
 released in March 2013\, with special emphasis on the non-Gaussianity 
 analysis which resulted in the highest precision tests to date of phys
 ical mechanisms for the origin of cosmic structure. Then I will turn t
 o the future and highlight the challenges and opportunities of the nex
 t generation of probes of the large scale structure of the universe ai
 ming to piece together the outstanding puzzles of cosmic past\, presen
 t\, and future - with some glimpses onto the lab bench of innovative a
 pproaches that are now emerging.<br><br>
