To me it's not about mass, but more like "maximum information density". There's a limit on the information density (rate of happening?), so when a parameter X changes too much, it affects other parameters -- they become constrained so that the total information density stayed within the maximum limit. That would indeed sound like some kind of computational limit if the universe was a massive CPU with constrained resources...

But I'm a layperson and I have no idea what I'm talking about :)

Information density is certainly on the right track, I'd put it as causality combined with a locality constraint.
