A generalization of Einstein's relativity proposing that relativity extends beyond motion and gravity to include other frames—reference frames based on scale, complexity, or consciousness. Extended Relativity suggests that just as motion is relative, so might be size (scale relativity), information (informational relativity), or even perspective (perspectival relativity). The theory unifies different kinds of relativity under a single framework: everything is relative to something. Einstein started it; Extended Relativity finishes it—relativity all the way down.
Extended Relativity Theory "Einstein said motion is relative. Extended Relativity says scale is relative too—physics looks different at quantum and cosmic scales, but neither is more fundamental. Relativity isn't just about velocity; it's about everything. The universe is a web of relations; Extended Relativity maps them all."

Get the Extended Relativity Theory mug.A theoretical hypothesis proposing that faster-than-light (FTL) phenomena, including warp drives and communications outside normal spacetime, preserve causality by appearing to observers within spacetime as if they were traveling at luminal speeds. This hypothesis extends the conserved causality principle to FTL scenarios by suggesting that spacetime functions like a computer plane: spectators (entities outside spacetime) perceive and maintain the causal relationships that observers (entities within spacetime) experience as potentially paradoxical. In practical terms, a warp drive doesn't violate causality because from the perspective of any observer within spacetime, its effects propagate exactly as if constrained by light speed—even though "outside," something else is happening. This elegantly resolves FTL paradoxes (like the tachyonic antitelephone) by proposing that causality is preserved not within spacetime but by the larger dimensional context in which spacetime is embedded.
The hypothesis has profound implications: it suggests that paraphysics and parasciences may be valid fields studying phenomena that interact with spacetime from outside—exactly the kinds of things that seem impossible within spacetime but might be perfectly coherent from a higher-dimensional perspective. It also explains why we can't perceive dimensions beyond 3D-4D: our observer-status within spacetime means we only experience the "projected" version of reality that preserves causal consistency. The extra dimensions are real; we just can't see them from inside the computer plane.
Example: "The warp drive test seemed to show the ship arriving before it left—a clear causality violation. But the Extended Causality Hypothesis suggests that from outside spacetime, the sequence was perfectly preserved; we just couldn't see the higher-dimensional context that made it consistent. The paradox wasn't real; it was just the limit of our observer-perspective."

Standing for "extended version", this is like "unrated version" — just a lot less misleading. Like the "unrated version", the "extension" of a movie is typically 5~10 minutes longer than the theatrical cut.
I watched the extension of that movie last night, and while it had some extra scenes, it wasn't nearly as misleading as the 'unrated version' claims to be.

Get the extension mug.This refers to the prolonged life stage between teenager and adult, that Millennials born 1990 or after has always been experiencing. This life stage is mainly caused by the generational inability for anyone born 1990 or after to become full-grown adult (e.g. due to the inability to afford moving out from parents' house, or due to the inability to afford starting a family), which works pretty much in the similar way to the New Zealand generational ban on smoking for anyone born 2008 or after.
With all the financial pressures on Millennials, extended adolescence has become the norm; it's hard to feel like an adult when you're still living at your parents' house, unable to start your own family, and not done with figuring things out yet!

A word that I have taken to take the place of a blank space in the English language. Taken from Latin, meaning "Something extended", Extensum is a word brought in to describe the phenomenon that occurs when an object becomes so integrated into the body's neural-map that the item ceases to be considered as an external object to the body. An Extensum is unlike a tool, which is used and put down, instead the Extensum is processed by the brain to be akin to a semi-permanent or permanent biological feature. This is a phenomenon that most often occurs amongst those with visual impairment, as the wearing of a pair of glasses for potentially over a dozen hours in a day results in this phenomenon occurring at an advanced pace. For the wearer of the Extensum, the psychological barrier between the world and the body thus occurs at the boundary of the Extensum, rather than just the skin. An object that would cause phantom pain, such as a prosthetic, or sensory vulnerability, such as a pair of glasses/hearing aid, would be an Extensum. To someone with an Extensum, to be deprived of it is not an inconvenience, but a diminishing of their physical presence. The creation threshold for an Extensum is once the brain ceases to perceive the physical presence of the object consciously, and begins instead to perceive only the sensory data it provides (sight, sound, stability, etc).
