In summary, the conversation discusses the visualization of 4D spacetime and the role of gravity within it. It is mentioned that while we cannot physically visualize 4D, there are models and examples that help us understand it. These models include combining spatial dimensions on a graph and using general and special relativity.

This is a FAQ; did you try searching for previous PF threads? This very question was discussed as recently as a few days ago.

If you take and combine two of the spatial dimensions say z and y then have time be your third dimension on a graph it is pretty easy. Its used in a lot of examples and what not in books.
