It's Official: We Were WRONG About the Big Bang

The word "universe" has gotten confusing by ambiguity. I've decided to call a contiguous spacetime, formed by vacuum decay in the inflaton field, a "universe." It isn't all of existence, but it probably is all that we can affect and all that we can get information from. Indeed, we can get information from only the part of our universe that is within our cosmological horizon, and we can affect less than half of that in principle. The multiverse is all of existence, with the inflaton field and all of its bubbles. Maybe there's more than one inflaton field doing the endless expand and decay thing. Inflaton fields have a lot more dark energy than bubble universes do, and that is why they expand so ridiculously fast - the expansion of bubble universes is very slow by comparison.
