Yggdrasil Hypothesis
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.

murderhobo
In a tabletop game, a murderhobo is a player who murders NPCs indiscriminately. This is normally derogatory, referring to a player who totally ignores quests, dialog, backstory, trade, world building etc.
The term is most common with Dungeons and Dragons, but it can be applied to most RPGs where the player is allowed to kill most quest-giving NPCs and NPC traders. E.g. Elder Scrolls, Fallout, Divinity original sin.
