JoinOur Place in the Spongy Universe
Physicist James Trefil once described our universe as "The Spongy Universe," comparing large-scale cosmic structures to the structure of a sponge. Because the sponge is such a good model for the universe, the authors modified this "Spongy Universe" activity for use with visually impaired students and pilot tested it at the Colorado School for the Deaf and the Blind.
