Quantum Foam
In John Wheeler's geometrodynamic description of quantum mechanics, the small-scale structure of spacetime is described as a quantum foam whose connectivities are not obvious part in large-scale physics, but whose behaviours become more apparent as we probe the surface at progressively smaller scales.
In wormhole theory, the idea of this "quantum foam" is sometimes invoked as a possible way of achieving large-scale wormholes without geometry change – instead of creating a wormhole from scratch, it may be theoretically possible to pluck an existing wormhole connection from the quantum foam and inflate it to a useful size.

Famous quotes containing the words quantum and/or foam:
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“Only the white, tremendous foam of the street has any importance,
The new white flowers that are beginning to shoot up about now.”
—John Ashbery (b. 1927)
