Once inflation starts, many models don’t politely stop everywhere at once. Inflation ends locally — in bubbles — while the background keeps expanding and birthing more.
Each “bubble” can be a whole Big-Bang-like region. Ours would be one pocket. Others might settle into different vacuum states — different effective laws, constants, particle menus.
That’s the leap from “inflation happened” to “our bang was one of many.”

Not because we’ve photographed another cosmos. Because the same inflationary framework that solves flatness/uniformity often has no natural off-switch that leaves only one bubble. Eternal inflation is a default in large classes of models — not a cartoon add-on.
