One density. Six fundamental constants.

What is this page for?

The Standard Model of particle physics — the most successful theory ever tested — needs 19 or more numbers fed into it by hand. Nobody knows why those numbers are what they are. They are simply measured and inserted.

The Big Flare-Up Theory (BFUT) proposes a physical answer. It identifies a single medium that fills all of space — the Spaticle field — and derives those fundamental constants from the properties of that medium. The key property is its intrinsic density, ρ_s = 5.9 × 10⁻²⁷ kg/m³.

This simulator lets you test how stable those derivations are. Move the sliders to change the input values. The six output quantities — the fine-structure constant α, the strong coupling α_s, the W and Z boson masses, the electroweak mixing angle, and the charged-lepton mass scale — update in real time. When the values match experiment, they are shown in green. The two charts below show how sensitive each output is to each input, and how the outputs scatter when all inputs are randomly perturbed simultaneously.

If the theory were fine-tuned — meaning the results only work for one exact set of inputs — the outputs would collapse immediately when you move a slider. Instead they remain close to the measured values across a wide range, demonstrating genuine robustness.
