The impact of a bowling ball on the shape of a stretched gridded sheet is often used as a tool to help some of us to better visualize how the presence of a mass influences the curvature of spacetime? However, while this kind of diagram is helpful, I think that it is misleading because it depicts the perturbation of only a single slice of the space-time continuum. In real fact, the massive object is totally enmeshed in a space-time continuum. Rather, I visualize a raisin enmeshed in a bread loaf in which the loaf represents the full continuum of space-time and no part of the raisin exists, indeed can exist, outside the space-time continuum. Am I thinking about this in the right way?
