pocket universes
Bubbles of existence
Pocket universes are self-contained realities existing separately from or within a larger universe.
The concept appears in physics, where inflationary theory suggests bubble universes spawning from quantum fluctuations, and in fiction, where characters create or discover isolated realms with their own rules: The wizard kept a pocket universe in his coat where time moved differently.
The "pocket" suggests something compact and portable, tucked away from ordinary space.
