## What is Holoverse?

What if our 3D universe is a hologram projected from a 2D surface?

The holographic principle, made precise by the AdS/CFT correspondence, is one of the deepest ideas in modern physics: everything happening inside a region of space, including gravity itself, can be described by quantum information living on its boundary. Holoverse turns that idea into something you can see and touch.

TWO LAYERS, ONE UNIVERSE
- The Boundary: thousands of glowing qubits on the edge of the universe, woven together by flickering threads of quantum entanglement.
- The Bulk: the 3D space inside, where spacetime bends, stars form, and black holes open, all projected from the data on the boundary.

HACK THE ENTANGLEMENT
- Tap two qubits to entangle them and watch matter condense in the bulk.
- Concentrate entanglement in one place and it collapses into a black hole.
- Entangle two distant points and a wormhole opens between them (ER = EPR).
- Cut threads of entanglement and watch spacetime respond.

THE DIMENSION SLIDER
Slide from 3D Bulk to 2D Boundary and watch the entire interior flatten onto the walls of the universe like a hologram, then rise back into three dimensions.

TWIN UNIVERSE MODE
Two mirrored universes, connected only by entanglement between their boundaries. Turn the entanglement up and a black hole forms in each, with every pair sharing a single interior: an Einstein–Rosen bridge. As in the real theory, the bridge cannot be crossed.

REAL PHYSICS, VISUALIZED
- Entanglement deepens gravity wells, inspired by the Ryu–Takayanagi formula
- Black holes with event horizons, photon rings and Doppler-beamed accretion disks
- Hawking radiation: particle pairs at the horizon, one escaping and redshifting, one falling in
- One bridge per entangled black-hole pair (monogamy of entanglement)
- Live readouts of entanglement entropy and spacetime curvature

BUILT FOR BEAUTY
Rendered in real time with Metal, with HDR bloom and up to 120 fps on ProMotion displays.

Holoverse is an educational visualization of the ideas behind the holographic principle. It is a simplified model inspired by AdS/CFT and the ER = EPR conjecture, not a numerical simulation of quantum gravity.
