This is not peer-reviewed research. It's an exploratory tool for understanding the mathematics of wormhole spacetimes. The geometry is mathematically consistent; the engineering it implies is impossible with known physics.

Picture the shortcut: a wormhole is a hypothetical shortcut between two far-apart places in space — a tunnel through the universe. This page doesn't draw a sci-fi picture; it runs the real equations to ask whether one could actually exist. The verdict: the math is self-consistent. You can describe a stable tunnel on paper. But propping it open needs a kind of “exotic matter” with negative energy that, as far as anyone knows, can't be made. For a metre-wide throat the shortfall is about 46 orders of magnitude.

What the simulator found

Result	Verdict	What it means
Geodesic traversal	✅ Works	Particles cross cleanly for zero angular momentum.
Angular-momentum filtering	✅ Robust	m=0 waves pass; higher-m modes reflect off a centrifugal barrier at the throat. Pure geometry.
Stability	⚠️ Conditional	Stable configurations exist only while exotic matter is continuously sustained. Remove it, it collapses.
Formation from flat space	❌ Impossible	Exotic matter can deform spacetime but cannot change its topology. Classically, you cannot create one.
Exotic-matter budget	❌ 46-order gap	A 1 m throat needs ~5×10²⁵ kg/m³ of negative energy density (≈5×10⁴² J/m³). The Casimir effect offers ~4×10⁻⁴ J/m³.

The bottom line: the mathematics is beautiful, the physics is self-consistent, and the engineering is impossible with anything we know how to build. The exotic-matter requirement isn't an engineering hurdle — it's the wall.

A symmetry worth keeping

In the sibling Kozyrev Mirror experiment — now shelved, because the effect reproduced but the explanation turned out to be wrong — a chiral spiral boundary generates angular momentum from zero. Here, a wormhole throat filters angular momentum, blocking high-m modes. One creates, one selects — and both are purely geometric, needing no material properties at all.

From the runs

m=0 wave transmitting through the wormhole throat — m=0 · transmits

m=2 wave partially reflected at the throat — m=2 · partial reflection

m=5 wave nearly fully reflected at the throat — m=5 · near-total reflection
