The statement of Hawking that we don’t need God, is simply a quote from Pierre-Simon Laplace, when Napoleon asked him why he did not mention God in his book on astronomy. Laplace said: “Je n’avais pas besoin de cette hypothèse-là”,What does physics have to do with proving or disproving whether God exists? Lately, the question has been keeping Father Robert J. Spitzer, S.J., Ph.D., very busy. Father Spitzer has mounted a highly visible challenge to physicist Stephen Hawking’s claim that “we don’t need God to explain why there is something rather than nothing or why the laws of nature are what they are.”

Wasn’t it Hawking himself who once said that he strongly believed there was some yet undiscovered physics restriction making time travel (of the kind discussed here, not of the relativistic dilation kind) impossible, based simply on the fact that we have never been visited by anyone from the future?Hawking’s statement on the Larry King show that time travel is possible raises serious questions about logical contradictions.
Yes. But I thought that I heard him say briefly on the LK show, that it was possible. I know that in the past he indicated that there would have to be restrictions or limitations on what would happen in the case of time travel.Wasn’t it Hawking himself who once said that he strongly believed there was some yet undiscovered physics restriction making time travel (of the kind discussed here, not of the relativistic dilation kind) impossible, based simply on the fact that we have never been visited by anyone from the future?
