- TL;DR Summary
- One possible end to the Universe is called vacuum decay, where a Higgs boson could transition from a false vacuum to a true vacuum state. This would create a vacuum decay bubble that would expand at light speed, destroying everything in its path. With a 95% probably, we know when this is likely to occur. But what is the likelihood that it has happened already?

One possible end to the Universe is called vacuum decay, where a Higgs boson could transition from a false vacuum to a true vacuum state. This would create a vacuum decay bubble (known as bubble nucleation) that would expand at light speed, destroying everything in its path.

According to Anders Andreassen et al. at Harvard University, they calculated with a 95% confidence level that vacuum decay will likely not happen until the Universe is between 10

But what is the statistical likelihood that vacuum decay has already occurred somewhere in the Universe after only 13.8 billion years, (about 10

Can anyone on this forum answer this question?

Although the answer to this question is almost certainly going to be very close to zero (maybe 10

I would be eternally grateful if anyone on this forum could answer my question:

Thanks in advance for your help!
