There is a reason for it to happen in this circumstance. The Higgs field is in a false vacuum state: that is to say, it mimics the effects of being in the lowest energy state, while what it's really doing is building up potential energy. When if there were to be a sudden spike in the Higgs field's energy distribution, for example a sudden surge of mass and the energy that would need to come with it, all that potential energy would be released as kinetic energy, hurling everything that has mass into its lowest possible energy state. However, as I've said, this might not even happen depending on the properties of the unforeseen influence.
"I lifted 85 kilos at the gym yesterday."
"I just ran 7 kilos this morning."
Both of these sentences make sense, and it wouldn't make much sense to assume the former meant anything other than kilograms, or that the latter meant anything other than kilometers. Likewise, it isn't really reasonable to have assumed I meant anything but the Planck length.
Doesn't all theoretical physics begin with imagination? Granted, if nothing like this were to ever happen then it might be more aptly described as "Philosophical Physics", but the principle remains.
