The website about WMAP says that since light travels at finite speed then the far-away objects we see are actually much older. So, am I understanding this correctly? Do the scientists study the CMB radiationbecause it is the oldest thing left from the Big Bang? And how does measuring the temperature fluctuations help scientists learn more about how long ago it happened, etc. ?
Thank you, if this is a stupid question, I apologize in advance.
