    As old and massive as the universe is, if it could have happened, it likely would have already.

      And that’s the thing:

      Assuming it did, you couldn’t see it approach until it hit you because it’s moving at the speed of light! It could also have happened, but just super far away such that it will never reach us due to expansion between its origin point and us being faster than c!

      Also just because the universe is frickin old doesn’t mean it is statistically bound to have happened. There are plenty of ways of making it even more astronomically unlikely but still possible…

      Basically, as big and old as the universe is, it’s easy to pick an even bigger number for the expected recurrence of a vacuum decay. So, it’s still possible.
