Cinematic physics sandbox

What if you could control reality itself?

FineTune Physics lets you rewrite three fundamental constants — gravity G, the speed of light c, and Planck’s reduced constant ℏ — then watch atoms, stars, planets, and cosmic history respond in real time.

This is not a textbook or lecture. It is an immersive experiment where a single slider can bloom into stable complexity, ignite a star, tear atoms apart, or collapse everything into nothing.

Experience it for yourself How it works

G: Gravity strength
c: Light speed limit
ℏ: Quantum scale

The premise

Three numbers. Everything else follows.

At the heart of physical reality are constants tuned with astonishing precision. Change them, and the familiar rules that make atoms stable, stars long-lived, chemistry possible, and life imaginable start to break. FineTune Physics makes that fine-tuning visible, playable, and visceral.

⚛️

Atomic scale

Watch hydrogen orbitals tighten, bloat, dissolve into quantum fog, or collapse into the nucleus as the Bohr-radius balance changes.

☀️

Stellar scale

See live stars flare, cool, shift color, fail to ignite, burn out too quickly, or cross into black-hole conditions with an accretion disk.

🌌

Cosmic scale

Track orbital speeds, period ratios, Schwarzschild radii, cosmic eras, and whether planets hold together or drift into the void.

Why it feels different

From abstract physics to immediate consequence.

Instead of reading that stronger gravity can shorten stellar lifetimes, you see the star brighten, the lifetime bar collapse, the heartbeat monitor panic, and a consequence alert tell you exactly what your universe has lost.

Plain-language stories explain what your universe contains — or why it contains nothing.
Beginner and Expert modes let visitors choose between guided intuition and equations.

Consequence alert

No atoms can exist.

Matter has imploded. Electrons cannot remain bound in stable orbitals. There is no chemistry, no stars as we know them, no planets, and no life.
