[QUOTE="PeterDonis, post: 6825224, member: 197831"] The original paper assumes that the bubble exists forever. Of course this is not physically realistic, but it makes the math much easier. :wink: It also neatly sidesteps all of the issues with causality that we are discussing in this thread, since the bubble in the original paper never changes speed or direction so it cannot cause any causality issues. It's only when you have multiple bubbles that can be created or destroyed, or a bubble that can change direction, that you can get causality issues. [/QUOTE]
