A model of the multiverse or cosmic structure as a fractal, branching, living system—the World Tree. It posits that
reality is structured as a network of interconnected "realms" (branches) growing from a common source (roots), with different physical laws or dimensional properties in different regions (Asgard, Midgard, Helheim, etc.). The "tree" is sustained by fundamental processes: the Well of Urd (quantum vacuum/zero-point energy), the Norns (algorithms of
evolution and complexity), and the serpent Nidhogg (entropy/decay at the roots). It views cosmic evolution as arboreal growth, with
new branches (universes, timelines) sprouting from quantum decisions or inflationary
bubbles.
Example: Imagine the Yggdrasil Hypothesis visualized as a cosmic MRI. Our entire universe is one "leaf" on a branch called Midgard. The stem of that branch is our inflation
bubble. Other leaves on nearby branches are parallel universes with slightly different constants. Deeper in the tree, other major branches host radically different
physics (an Asgard-branch with stronger nuclear
force, a Helheim-branch dominated by dark matter). The trunk is the shared origin, the roots tap into the chaotic
pre-physical substrate, and the whole tree is "alive"—meaning it grows, adapts, and has a lifecycle.
