Claim ds-011 · Atlas v1.2.0

The Dark Dimension scenario ties the dark-energy scale to a Kaluza-Klein scale via the AdS distance conjecture, predicting a single extra dimension of roughly micron size.

ds-011Speculative interpretation

The Dark Dimension scenario ties the dark-energy scale to a Kaluza-Klein scale via the AdS distance conjecture, predicting a single extra dimension of roughly micron size.

Why it is stated this way
It is one of the few places in this debate that yields a concrete, near-term testable number, which is why it attracts attention out of proportion to its epistemic footing.
Scope and limitations
The scenario is built on the AdS distance conjecture — itself unproved — combined with phenomenological input. A testable prediction is not evidence for the premises that generated it.
