I think it&#x27;s a fine way to introduce the notion that mass bends spacetime, and &quot;gravity&quot; is the phenomenon of traveling that curved spacetime. We can show the warping of a two-dimensional plan by projecting it into the third-dimension, giving an intuition by analogy. I don&#x27;t know how to actually show warped three-dimensional space, since we can&#x27;t project into into a fourth-dimension.
