This is a topic I like to muse on day-to-day - I find visualising hyperspace interesting. Extending the same notion of there being a time dimension that is less dense the further it is from a gravity well - well, it changes certain aspects of how one might look at the universe, such as, say, why distant galaxies are redshifted, why galaxies rotate evenly throughout their volumes, and why the speed of light is a thing.
