Will there be infinite expansion or will the big bang eventually get reversed in to a big crunch? This question might not even be relevant if this bubble phenomenon rips the entire universe apart. What if such a bubble already exists beyond the horizon and will devour our galaxy in a billion years.

We have no way to know what the resultant physics would be like within the bubble, so there is no way to even speculate about what would happen.
Exciting times ahead. Who knows what will happen… if anything at all. It’s also entirely possible that nothing special is going on or ever will be.
