PPT-If the universe were

perfectly uniform then how come the microwave background isnt uniform Where did all the structuregalaxies clusters etc come from Density Fluctuations Why we need them Can we understand where these variations come from. Expanding Universe – consistent w/ a Big Bang?. Olber’s Paradox. Large Scale Structure and relation to Dark Matter. Evidence for the Big Bang. The Cosmic Microwave Background. The abundances of the elements. Homogeneous and uniform cosmic expansion . Hubble constant determines scale factor . Hubble diagram was based on a limited distance scale calibrated by Cepheid variable stars in relatively nearby galaxies. w. here does it end?. Chris North. Cardiff University.

In an expanding universe the relationship between redshift and distance depends on the cosmological parameters (i.e. the geometry and expansion of the universe). Why?. From t=0 to the CBR Era. The CBR. Universe hotter & denser in the past. For T high enough - ionized & opaque – blackbody. and. Currently T=2.726 K. z(opaque. . transparent)~1100 K.
