One of the exciting aspects of some fields of physics is that they involve calculating the expected time until the Universe ends or experiences fundamental shifts that would render most if not all …
I’m a bit curious as to what time span exactly they’re measuring here? Because it’s not like the whole universe would die all at once. Heck, vacuum decay could have already begun somewhere. If so, it would propagate outward at the speed of light, which is quite slow compared to the size of the universe. If it’s far enough away, it may never reach us at all due to the space between expanding.
In any case, this is all theoretical and may not be an actual thing that could happen at all.
Kurzgesagt has a nice video on vacuum decay for anyone interested
