Can someone tell me why people age our universe at about 13.7 billion years? I know this is done with WMAP, but I can't seem to make much of that. Is there a measurement that aims to explain the age of our universe with just the help of our solar system? I know there are some methods of...

c is just saying it's constant, it doesn't say anything about the speed of the light.

Okay thanks for clearing that up. Another question then: When is the value of redhift largest? When a galaxy is receding faster than light? When does redshift get shifted to infinite wavelength? Does every object that's at a same distance from us (earth) have the same redshift?

Hi all. I was reading: http://www.astro.ucla.edu/~wright/doppler.htm but I'm failing to understand this part: My understanding is that a galaxy cannot move faster than c (the speed of light). Why then could a galaxy moving close to c have a recession velocity greater than the speed of light...
