For example, add two identical balls of dough together…
““For example, add two identical balls of dough together, and the new radius of the combined ball is not twice what it was; it's only about 26 percent larger. Why? Because for ordinary materials in a sphere the radius grows as the cube root of the mass-double the mass and you only increase the size by 26 percent.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Combining equal masses yields a smaller radius increase due to cubic scaling
In simple terms: Merging spheres grows radius only ~26% because volume scales with cube of radius
