    Vacuum Metastability: Estimating the Lifespan of a False Vacuum”

    well I've seen in a nature article for example, a quote that said the chances are 1 in 169billion. it seems like that scientist involved must at least have had a model. after all, there are models for quantum tunneling in other circumstances. however, now i think the point is moot for...

    Vacuum Metastability: Estimating the Lifespan of a False Vacuum”

    i still can't seem to gather how likely the event is or even what the regional probabilities are. i suppose it depends on unknown constants in nature but arent there conjectures based on existing models? like.. if we assume higgs boson of 115Gev then... a probability of so many years.. etc.?

    Vacuum Metastability: Estimating the Lifespan of a False Vacuum”

    i understand that academic journals need subscriptions to keep alive, but some of those articles are old. have any been released to the public yet? i can't actually view any of them. thanks though.

    Vacuum Metastability: Estimating the Lifespan of a False Vacuum”

    it doesn't seem to give any good news though. "If our universe is metastable, the expected survival time may be not much larger than the current Hubble age." all the rest is referred to as a "modicum of hope"

    Vacuum Metastability: Estimating the Lifespan of a False Vacuum”

    i appreciate the article, as its one i actually haven't seen yet - and I've looked at about 100. ill read it more in depth in a bit here but one sore point with me is that it reiterates a point that i don't find reassuring: "the decay time is at least a Hubble time." its like...

    Vacuum Metastability: Estimating the Lifespan of a False Vacuum”

    I recently learned about the possibility of the universe being in a false vacuum, but it seems really hard to find real information on it. I've looked at academic papers but they're well above my undergrad math. Does the acceleration of inflation imply that we do exist in a false vacuum...
