In your analogy, how does one level of the pyramid interact with the other? Or does it?
Darn hard question that one. A quick answer is, yes they interact. The nuclear conversion of atoms to electromagnetic waves for example, is an interaction between different levels of the universe, where a higher level is converted to a lower level. Any universe level, such as our level, contains all the lower level universes.
The constants act to slow down such conversions, until such as as sufficent force gathers to break apart the "glue", the causal power equalisation, that are the constants. They are a kind of barrier, between one universe and another. To put into words, or even just conceptualise, the "how" of this interaction is extremely difficult. In normal circumstances the constants act like a sieve, that prevents some universes from passing through but not others - ie radiation for instance can constantly extrude from atoms, but electrons within the atom will not pass the barrier unless something on the other side of the barrier causes the breakage or destruction of same barrier. The barrier is only different from what is not the barrier, by virtue of the greater degree of self-containment. The barrier is more static, it has far less causal extrusion, because the opposite powers are constantly acting on each other in (near) equal degrees, so this forms a stasis. Of course, no thing causal can ever be perfectly equal, so over time existing barriers decay and new barriers are caused to form.
As an analogy think of the Ozone layer as a barrier, where the Sun is where the Expansionary force is dominant or stronger and the Earth is where the Contracting force is dominant. The ozone layer blocks most of the expansionary force coming from the sun in the form of sunlight, it however does not block all the light but only the ultravoilet range. Something stronger like an asteroid simply breaks part of this barrier apart. That sunlight that does pass through is absorbed by unifying with the earths excess of contracting force, or reflected out into space. The barrier also is a thing with a stronger contracting force, and it too absorbs sunlight and changes.
