Universe

When scientists say that the universe can simply come out of nothing without any divine intervention, they think of the universe in terms of its energy content only. In the book ‘The Grand Design’, page 281, scientist Stephen Hawking has written that bodies like stars or black holes cannot just appear out of nothing, but a whole universe can. The message is very clear from this: The total energy of a whole universe is zero and that is why it can come out of nothing; but stars or black holes will fail to do so, because their total energy is not zero.
