Are we Just a Decayed Vacuum?

We don't really know much of anything about the very start of the Big Bang, but it now looks very likely that it was followed by a rapid inflation period. That means the universe was in a false vacuum. Then that rapid inflation ended, so the universe found its way out of that false vacuum to one of much lower energy density. So in that sense, yes, we're living in a decayed false vacuum.
The universe is still inflating a little bit, so it seems likely that we're still not in the lowest energy vacuum. It may decay again.
