Reply to comment by Lirdon in Can someone explain what spacetime is? by Dusthip

When conceptualizing spacetime does the sheet only represent a "slice" of spacetime in the analog? If so, could you take the same concept and represent it as a weighted sphere embedded in a large sponge, with the sphere causing the sponge to sag? The sponge would sag more in the immediate area of the sphere and less so as you move away from the sphere?

Basically. There is no up down left or right in space, the massive object is warping in 3 dimensions, not just a 2D sheet.
