Thank you, Stephen Hawking. And yes, Dr Hawkings comments are exactly where you got this argument that talking about the cause of the Big Bang and "before the Universe" is meaningless. But that goes to show that General Relativity alone cannot explain the Big Bang. The current scientific explanation for the Big Bang involves quantum fluctuations of the Higgs Field. It is the concept of
imaginary time that provides a better framework for discussing the cause of the Big Bang and what may very well have existed before it(in imaginary time of course!).
No, that's not correct. The symmetry breaking of the Higgs field only explains how elementary particle got their masses. We don't know what caused the Big Bang because in order to explain that, we need a theory of quantum gravity. Alex Vilenkin's theory of chaotic inflation and bubble nucleation may be an explanation for the Big Bang.
