Question About the Universe

First of all, let's do a little math. The current consensus on the age of the universe is somewhere around 13.73 billion years, with an error margin of about 120 million years.What's important to keep in mind is the vastness of time periods we're talking about. While 120 million years may seem like small change when comparing it to the total age of the universe, realize that a lot can happen in the way of cosmological evolution during the course of 120 million years.This is from your article itself: Seeing as how a billion (1,000,000,000) is one thousand million (1,000,000), this gives plenty of time for this star to have appeared sometime after the Big Bang.In any case, someone else on this forum can probably explain it with greater detail than I can. Cosmology isn't my forte; I'm a biology major. Edited by RDK, : No reason given.Edited by RDK, : No reason given.
