Diaspora Chapter 15: 5+1 - Greg Egan

"Potential energy wells in 3 and 5 dimensions

In 3-dimensional space (below left), gravitational attraction is inversely proportional to the square of distance. In 5-dimensional space (below right), it's inversely proportional to the fourth power of distance; the central well is steeper, but further away the surface flattens out more rapidly."


4.5 out of 5
