Mathematicians, and therefore physicists and cosmologists, view dimensions in a different light than the rest of us do. The Big Bang was quick, but the pace was quick, too. As much happened in the first 3 seconds as has happened in the universe ever since. It is useless to talk about the instant of the Big Bang since infinitely many things were happening in an infinitely short time. Talk of before the Big Bang is without meaning.

In other words they don't have an answer.
