I have used the forum search function with the key words "block", "physic" and "physics", but found no related threads or posts whatsoever. Could you link the thread and maybe specify which other mods provide a similar functionality?

There is, actually, and it would fit in very well with Finite Liquids - which it is incompatible with, sadly. I am talking about the Block Physics Mod, which makes Dirt, Sand, Grass and Gravel susceptible to gravity. All stone blocks also need to be properly supported, lest they collapse. This means that when building any architecture, you will also need to pay attention to statics - and Creepers exploding near your home might actually make your architecture crumble. Interested?
