Model a wormhole.
Honestly.

Not a picture of a wormhole — the actual physics. The Morris–Thorne metric, particles falling through the throat, waves bending in curved space, and the one problem that ruins everything: exotic matter.

This is not peer-reviewed research.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. Where that matters, this page says so — out loud.

What this is (and what it is not)

What this is

  • A correct implementation of the Morris–Thorne / Ellis metric
  • A geodesic solver that sends particles through the throat
  • A curved-space wave equation you can watch in real time
  • An honest map of where the physics breaks

What this is not

  • A claim that wormholes can be built
  • A source of exotic matter or negative energy
  • A topology-change mechanism (that needs new physics)
  • Peer-reviewed, or pretending to be

What the simulator found

ResultVerdictWhat 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 ❌ 60-order gap A 1 m throat needs ~10⁴³ kg/m³ of negative energy density. The Casimir effect offers ~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, 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. That's the prettiest thing in this little suite.

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
