I have read a lot about eternal inflation and as I understand it Guth and others are now arguing that once inflation has started, it is an ongoing process. However, my question is, once inflation had finished in one Universe and inflation had started somewhere else, wouldn't the expanding inflationary domain soon collide with the Universe that had already inflated? I mean, what stops the spacetime bubbles of colliding with each other?
