There's no cosmology to back up the theory, but such a formulation also means that every possible Earth gets "born" at a different time.
So, sufficient distance travel would be the same as time travel.
Even so, it doesn't help. Whatever world you're trying to find, it will take you an infinity to find it.
Which reminds of my tagline of long ago -- "I once thought that I would live forever ... but that was an eternity ago."
There's no cosmology to back up the theory...
From the article:
Now, inflation is no airy-fairy theoretical idea. It has been pretty much confirmed in the past year by data collected by Nasa's "Wilkinson Microwave Anisotropy Probe", which is observing the dim "afterglow" of the Big Bang fireball from far out in space. And inflation predicts more than that there are an infinite number of bubble regions like our observable universe.
