    Will we seeing the vacuum apocalypse coming or not?

    The only thing scarier than the vacuum apocalypse is knowing that it's coming.

    Some sources say that the bubble will expand at the speed of light so we'll never seeing it coming. But there is some mention in some places (Wikipedia) that it is "almost" the speed of light. Well almost the speed of light isn't the speed of light. Even if it is 0.999999999 of the speed of light, if the bubble starts one billion light years away we'd see it start one year before it hit us.

    Now that is terrifying because that last year of existence would suck.

    I hope it starts in Andromeda. Then there wouldn't be time to get the word out.

    Why? Because we’d all be in pain? There are many people who are told they will die in a year, and it can sometimes be a fulfilling last year. It doesn’t seem that bad to me, knowing that we will all vanish together, painlessly. Do you prefer dying one by one to cancer or vascular disease,

    Society would breakdown completely if word got out that the universe was going to end.

    That's why the actual light speed expansion is benign. Everything is humming along nicely then it just isn't.

    Often said, but I'm unconvinced. I think the way things go in the film Last Night (1998) might be nearer the mark.

    I suspect that most people wouldn't believe it any more than they believe any of the other frequent predictions of the end of the world.

    Still. More favourable than the Big Rip or Big Freeze. At least everything is fine until it isn't. The other scenarios are just despair.

    But everything is just despair, when you think about it.
    Life is so much easier once you've embraced the despair.

    A reference, please.

    This all started back in 1982. Turner & Wilczek, Nature 282: 633-4. Take a look at the last paragraph. Also note the sentence within that paragraph beginning "There is no immediate cause for concern ..."

    As usual, the only potentially interesting statement in the Wikipedia article is the one lacking a citation. I've never seen a suggestion that this bubble would expand at anything other than the speed of light.

    It's in the section of bubble nucleation.

    https://en.m.wikipedia.org/wiki/False_vacuum

    "Therefore, after the bubble is nucleated, it quickly begins expanding at very nearly the speed of light."

    But that's what I'm asking in this question forum. Is it the speed of light or very nearly the speed of light?

    That's what I was pointing out. No supporting citation for the intriguing "very nearly" from Wikipedia (which is an ironically common problem). But lots of easily found references saying "at the speed of light". I'm not disposed to believe Wikipedia without evidence.

    The Odds Are Against It

    Thanks, all.

    This has 1 chance in 10^9 years of getting on my list of worries.

    Well said. Didn't some Indian guy say something along those lines a few years back?

    Original with me, as far as I know, but I'd never claim unique insight for something so obvious.

    Hard to imagine living forever, or even for centuries. Life's repetition would eventually get boring.
