How old is the Universe?
Current models of the Universe's past, together with observations indicate that the Universe is roughly 14 billion years old. Now, we know that our models aren't exactly correct, but they are pretty close to the correct answer. That means that there is a little wiggle room in this number, but it's pretty nearly right. In fact, astronomers have seen stars that are at least 10 billion years old.
