Quantum Foam 3D: Time-Energy Uncertainty

Zoom out from a single virtual pair to the whole vacuum: this 3D scene fills a volume with dozens of simultaneous electron-positron fluctuations, each one borrowing an energy ΔE and repaying it within a lifetime Δt = ħ/(2ΔE), exactly as Heisenberg's time-energy uncertainty relation requires. Two InstancedMeshes carry the entire population — hundreds of independently timed pairs rendered in two draw calls — while the camera drifts through the foam or orbits under your control. Raise the energy scale and watch the whole field flicker faster; raise the density and watch the vacuum's constant energy turnover become visible, the same physics behind the Casimir effect and Hawking radiation.
