This is a good idealisation, but what happens when your definition of "energy" breaks down?
My definition of energy never breaks down!
Seriously then, there is a change. Receding to the BB and the point where everything breaks down. No time, no space, no energy. There is a change from one reality to another. That other reality is indefinable but I don’t see why it can not exist.
My answer is that the definitions do not break down it is that they no longer apply.
Causality is an internal property of the Universe in those areas with a well-defined time dimension. If there is a minimum time (at the Big Bang), then you have found at least one point in which there is not a well defined time dimension - and hence a point at which naive concepts of causality cannot apply.
I understand.
If you were to picture the Universe in your mind, would you see it from the inside or the outside? As soon as I imagine an outside to the Universe it becomes incorporated.
Well, you have managed to find a point for which there is no clear definiton of energy, nor a clear sense of causality. So I would have to ask: what do you mean by "created" and "destroyed"?
I mean into or out of existence. Whatever the energy was before it was energy, it still existed.
I guess that I am supporting the idea of an oscillating infinite continuum. (edit; and if such a thing exists I think that it answers the question why something rather than nothing.)
