Going with the paper's result: with 95% confidence, more than 10^58 light years. :)

- amelius 9y agoI think that was about the entire Universe, not our local part of it.
- T-A 9y agoThe result reported by this paper is decay rate per unit volume (see Eq. 6.26). That tells you how long it takes for a bubble to nucleate. After that, it expands at the speed of light. How long does it take for a bubble expanding at the speed of light to destroy an infinite universe?
- empath75 9y agoSo it would be multiple bubbles spread throughout that would wipe out an infinite universe.
- T-A 9y ago... which is expanding. So now you have a percolation problem: what grows faster, the bubbles or the universe? The latter is also thought to be expanding at an accelerating rate, which leads to funny scenarios like this: https://arxiv.org/abs/1503.08130 https://arxiv.org/abs/1503.08130
