We estimate, using this technique, the universe is about 14 billion years old. That s right. And if this turns out to be true, it may be a relief to some cosmologists. There was a problem in cosmology known as the age crisis. Remind us what cosmology is.
Cosmology is the study of the shape, structure, and dynamics of the universe.
And there are some stars in the universe which are thought to be about 12 billion years old. And at one time we thought the universe might only be eight or ten billion years old. So it was this kind of strange situation where it s like you re actually older than your mother, and that doesn t seem possible. Oh, yes, I would say so, and I would say that we re very skeptical too. As I said, we d like to find a more mundane explanation for it.
