The Wilkinson Microwave Anisotropy Probe (WMAP) survey sets the age of the 
universe at 13.7 billion years. The redshift of the oldest observable light in 
the CMB indicates a distance of 46.5 billion light years. Given the 
equivalence of time and distance implied by the speed of light (assumed a 
constant over all time), this would indicate the furthest observable light is 
substantially older than the age of the universe itself. How is this possible?
