My Comment: Be careful and say “gravitational potential field”. That is what real “gravitational engineers” use

The gravitational potential field can change its value at every voxel in space at every moment. The acceleration field is just the vector or tensor gradient. Potentials can flow. They can have turbulent flows, compression, shear and state transitions. They are easy to measure these days and easy to model.

I use several visualizations, but the most common is particles that can flow and interact. And, where the density and temperature can change. The reason is there are lots of people who can work with gases with real properties and many algorithms. Just make the particles small enough with enough energy density and gradients to match real gravitational potentials.

I learned from Steve Klosko when I worked with him on calibrating the earths gravitational potential models – to be very practical. To take a “gravitational engineering” approach, and not get hung up on technical things related to the visualization when the real thing is there, can be measured and used.

At the same time Joe Weber and Robert Forward (Detectors for Dynamic Gravitational Fields) showed me how to make communication systems, detectors and generators and showed how to calculate what was needed. The gravitational potential field is there, just use it, not blab about it and hand wave. Engineer are pretty crusty and tough minded. Get the job done. Stop playing on trampolines and rubber sheets, and make ships that can explore and develop the whole solar system.

“Balls on sheets”, what a crock, get real!
