I know of the gravitational analogy. The bending of spacetime due to a mass is analogous to a ball placed on a sheet, other balls in the region will be "attracted" towards eachother. My question is, if we have to simplify our 3 spacial dimensions to 2 dimensions for the analogy, does that insinuate 4 spatial dimensions, making a total of 5 spacetime dimensions?(adsbygoogle = window.adsbygoogle || []).push({});

The only alternative is that objects bend spacetime along thetimeaxis, (in other words that extra dimension in the analogy is time itself) This however is extremely strange and if it is the case then my mind is blown and I would require some explaining.
