The way Life and Death interacted was relatively simple. The two Laws represented polar opposites, and while they shared a symbiotic relationship, it was also common for them to clash at a moment's notice.
Reincarnation represented the delicate balance in which these two opposites harmonized.
Space and Time were more convoluted in many different ways. For one, there wasn't a defined boundary between them, and they were always interacting as if they desired to be one. Along with this, space and time didn't have a middle ground, rather their convergence point was far less of a point and more of a macrocosm in itself.
After all, the convergence of space and time created the "container" in which reality existed.
Now, with these facts in mind, how did space react when it mingled with Life, and what about Death? The same could be said about time. How did these unrelated forces interact?
