The Maldacena–Susskind ER = EPR conjecture proposes that a maximally entangled pair of systems (an "EPR pair") is dual to an Einstein–Rosen bridge — a wormhole — connecting them in the bulk geometry. This sim treats each of the N sliders' Bell pairs as one unit of shared entanglement and geometrizes it with the Ryu–Takayanagi entropy–area relation:
S = A / (4 G) ⇒ A = 4 G S, r = √(A / 4π)
Each Bell pair contributes exactly 1 bit (ln2 nats) of entanglement entropy, so S = N bits. The bulk coupling G is a schematic stand-in for Newton's constant — turning it up lets the same entropy support a fatter throat.
- + Entangle a pair / Measure a pair — grows or destroys shared entanglement. Measuring a pair collapses it, entropy drops by 1 bit, and the throat visibly narrows; at S = 0 the two mouths pinch apart completely — no wormhole, no entanglement.
- Mouth separation — moves the two mouths apart in ordinary 3D space without touching the throat geometry. This is the conjecture's central, counter-intuitive claim: the wormhole's interior length is set by entanglement structure and horizon dynamics, not by how far apart the mouths sit in the ambient world you can walk around in.
- Send probe through throat — launches a marker along the interior. For the eternal two-sided wormhole this sim schematizes, the throat is non-traversable: classically it pinches off before anything crosses (the probe stalls and is reflected), consistent with focusing theorems. A staple prediction the theory does not make: no faster-than-light signal ever gets through — the no-signaling theorem holds regardless of how much entanglement is shared, exactly as with ordinary quantum teleportation.
This is a pedagogical, dimensionally-schematic model of an active but unconfirmed conjecture in quantum gravity (holography / AdS-CFT), not a claim that spatial teleportation of macroscopic matter is achievable.
