About The Cosmic Forge
The Cosmic Forge
"Every atom of gold was once the last heartbeat of a dying star."
Welcome to the Cosmic Forge. A simulator of time, matter, and destruction.
Operating Instructions
- Stellar Evolution: You are the master of this newborn star. Press and hold the core to inject energy, fusing light elements into heavier ones. Forge your way from Hydrogen (H) to Helium (He), Carbon (C), and Oxygen (O).
- The Curse of Iron: Every star has its fate. When fusion reaches Iron (Fe), the star loses its ability to fight gravity. The screen will turn red as immense gravity tries to crush it. You must hold continuously to resist collapse and sustain its life.
- Kilonova Event: Destruction is rebirth. When pressure reaches critical levels, the iron core will collapse into a neutron star, triggering a merger and a magnificent kilonova explosion. In this cosmic firework, the rarest treasure will be born — Gold (Au).
Cosmic Trivia
The gold ring on your finger is the remains of a massive star's death. Every atom in our body comes from stars that exploded billions of years ago.
