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.

Frothability
The measure of an emotional and over zealous consumer in an upwardly charging market, also known as a bull market. It's characterized by rising asset prices, increased investor confidence, and favorable growth in the markets, bro.
The frothability was evident as over-zealous consumers eagerly engaged in bidding wars, driving property prices to unsustainable levels reminiscent of previous speculative bubbles.

pod person
A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.
