Question:
How can people know when the universe was created?
Replies:
They cannot, of course. We know that the universe is expanding, and we know
how to run the expansion back to a "point", this enables us to give a date
to the "age" of the universe. We do not, however, know very well how the
expansion went when the universe was very "small". Furthermore, quantum
mechanics makes the concept of a starting "point" very difficult. Probably
the best book for an overall survey is Steve Weinberg's "The First Three
Minutes", a very enjoyable read.
