**zero-bubble**(also written as "

**0-bubble**" or "

**0b**") or "

**sponge**" is a bubble shapeframe (stereogram*) with no inflatons (scalar fields responsible for blowup from a single point [0-brane]). A

**0b**is a type of homeomorphism as a

*totally twisted*loop, and formally marks the end of a proof.🔲Greater than or equal to three (3) spatial dimensions.

**Sponges**are the ideal [most secure🔐] ¢ent structures [signed certificates] for a closed🔒 string (and thus, fibor). Taken by themselves,

**zero-bubbles**(frictionless assets) are considered solved puzzles🏁 (ie. completely mapped/encrypted/melodic/folded).
