DESCRIPTION:The dimming of Type Ia supernovae could be the result of Hubbl
 e-scale inhomogeneity in the matter and spatial curvature\, rather than si
 gnaling the presence of a dark energy component. We will show that such mo
 dels can account for the lithium problem of standard Big bang nucleosynthe
 sis and fit the detailed spectrum of the cosmic microwave background (CMB)
 . We will describe a full treatment of the radiation in inhomogeneous mode
 ls which is necessary if we are to understand the full constraints from th
 e CMB\, as well as other observations which rely on it\, such as spectral 
 distortions of the black body spectrum\, the kinematic Sunyaev-Zeldovich e
 ffect or the Baryon Acoustic Oscillations. Although still in the context o
 f toy cases\, the agreement of inhomogeneous models with observed backgrou
 nd dynamics of the universe suggests they deserve further investigation.\n
