It’s in his book- he explains how the matter and such could come to be from a vacuum. But I’d think that there’s a difference between a vacuum and true nothingness.
I concur. A vacuum is just pushing the question of the existence of everything back one step more. It’s still working within natural science and not metaphysics.
This is just an absurd notion. Theories of physics are not mathematical theories. Is gravity a mathematical theory as well?
It is. So is the Big Bang. In fact, the Big Bang, as it was first formulated by Georges LeMaitre, is really just a big, elaborate equation. Mind, that equation is based on our quantitative knowledge of science. As far as we understand physics, it is likely correct. But without ever having seen it, or being able to experiment to verify or contradict the Big Bang, it’s an educated guess, and not based on any direct or even closely related evidence. And how could it be?
Nevertheless, belief in the Big Bang is not an act of blind faith, because it is a conclusion reached through circumstantial evidence and predictions based on more remote evidence. That’s actually rather common in science. There are many things we teach as true based on things other than direct observation and experimentation - tectonic plates, for example.
But you managed to defeat your own argument, actually. The wiki page you linked lists M-theory as an example of a scientific theory.
As the section on physical theories explains, and as theoretical physics does still more explicitly, “theory” means something different in physics, especially theoretical physics models like string “theory”.

Now, that string theory is a physical theory but only a scientific hypothesis doesn’t mean it’s not necessarily true. But testing would be highly desirable before proclaiming this as
the certain theory of everything. As for its effect on Christianity, I am agnostic. But if evolution, heliocentrism, and archaeology haven’t killed Christianity yet, I have my doubts any other natural science could.
Different definition of “universe.” Under your definition it would not be proper to call the big bang the beginning of the universe, since the big bang refers to the expansion of matter /energy/space time from a point- all of which already existed.
True. The Big Bang would be the beginning of our corner of the universe, if any other things pre-existed this area, and the universe would encompass everything that has existed before and alongside us, even if it did not come from the Big Bang. If nothing did, this is the universe.
But let’s say, for example, the parallel worlds interpretation of quantum physics was right. What are those parallel worlds in relation to us, if they exist, like we do? Is it correct to call them “universes”? Remember what a universe is defined as.
Moreover, under your definition of matter, by what logic do you suppose that all string theory and such assume that matter is eternal?
The attempt to explain the existence of finite things with other finite things seems to assume we do not need to concern ourselves with infinite things. Like God. And as nothing comes from nothing, and an infinite regress is absurd, it seems to me the natural assumption of naturalism and materialism is that material, in some form or another, is eternal.
In other words, recruiting string theory to disprove or explain away God seems to assume matter has the quality of being eternal. Which, if our Greek forebears are any sign, is an understandable, rational belief.
