Duke Andrews and Quantum Foam

Here we see a page from American Scientist magazine, the July-August issue from 1995. At the lower right, the drawing is labeled,

An embedding diagram (with a 0.02 percent probability) illustrating the quantum foam thought to reside in the singularity inside a black hole. From Black Holes and Time Warps.

Pasted over that page are three drawings by Duke Andrews, an artist whose work sometimes appeared in Salon: A Journal of Aesthetics.
The Andrews drawings date from 1986-87, predating the Quantum Foam illustration in American Scientist by eight or nine years. What does it all mean? Beats the hell out of me.
