This, in a nutshell, then, is the General Theory of Relativity, and its central premise is that the curvature of space-time is directly determined by the distribution of matter and energy contained within it. What complicates things, however, is that the distribution of matter and energy is in turn governed by the curvature of space, leading to a feedback loop and a lot of very complex mathematics. Thus, the presence of mass/energy determines the geometry of space, and the geometry of space determines the motion of mass/energy
Please remember that this is the base for General relativity. Curvature of space time is directly determined by the distribution of matter and energy contained within it. Suppose if it is empty no curvature at all.
When an atom bomb is detonated, energy, afresh is released into open area. This is additional energy only. It pushes the existing energy leading to eddies in the space time.
Please remember total energy is not coming from the atom bomb.
Ok, it is very difficult or impossible to prove it, but it is appearing before us. If an atom bomb is detonated in empty space, 2d, where no matter and energy exists, small amount of energy released makes no wonders, moves out.
Suppose if it is on Moon where gravity is weak and thus curvature of space time, and distribution of matter and energy. Here additional energy released into the space is same, however energy present in the open area is weak and thus eddies.
Friends, don't search text books, this is purely mine, "New" theory/idea only.
