I'm just wondering why there exist objects like http://en.wikipedia.org/wiki/HD_140283 (The Methuselah Star) that have projected ages older than the projected age of the universe itself. That, where does the conflict between the age of these very old stars and the calculated age of the universe come from? Is it a quirk in how star ages are computed, like that these stars are somehow anomalous in their content of gas and other chemicals in relation to their size and luminosity in a way that would interfere with the calculation? Or is there some kind of relativity weirdness that allows for the existence of objects "older" than the universe itself (the star was moving very fast, or was in a very high mass-density region, or was moving in such a way that its redshift interfered with observations)? Please help me, I'm very confused.
