We return to listener questions on whether Hawking was right or wrong to dismiss God as a cause of the universe in his new book "The Grand Design".
John Polkinghorne is a theoretical physicist and Anglican Priest in Cambridge. Hugh Ross is a Christian physicist and founder of "Reasons to Believe".
They tackle questions on whether the multiverse is really an alternative to God in explaining our fine-tuned universe. What physicists really mean when they say the universe came into being "out of nothing", and whether the massive size of the universe makes our existence insignificant.
