CENTER FOR ASTROPHYSICS NEWS RELEASE

NASA's Swift satellite already has seen a gamma-ray burst (GRB) with a redshift of 6.29, meaning that the progenitor star exploded about 13 billion years ago, when the universe was less than a billion years old. Theorists Volker Bromm (University of Texas at Austin) and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) predict that one-tenth of the blasts Swift will spot during its operational lifetime will come from stars at a redshift of 5 or greater, that lived and died during the first billion years of the universe.

I've always thought about the stars with regard to the age of the universe. Here we have a star bursting at 13 billion years old, but how old was it before it burst? Only 1.5 billion as we know the age of the universe now.

Our sun is middle aged at some 5 billion years old and should burst at around 10 Billion years old, so doesn't it sound reasonable that the universe is much older than 14 billion years old if we can find a star that exploded 13 billion years ago and averaging its middle age at 6.5 billion?

I know not all stars act the same but the law of averages should explain some and question the age of the universe.
