In 2015, LIGO made the world’s first direct detection of gravitational waves with the event GW150914, confirming for the first time in history the existence of binary black hole systems.In most space-themed games, you pilot a spaceship or colonize planets. But in this game, you become a celestial body. Start as a lonely asteroid, grow by absorbing smaller objects, and evolve step by step—from asteroid to planet, to star, and ultimately to a black hole that devours everything. All of this unfolds in a vast sandbox universe driven by real physics.Gain mass by absorbing smaller asteroids and progress through multiple cosmic stages, each unlocking new abilities and challenges:As a planet, nurture life and protect your own world;As a star, your powerful gravity can capture planets and build your own planetary system;As a black hole, nothing can escape your grasp.Explore freely in a universe governed by authentic gravitational and orbital mechanics, and create your own cosmic system.Key Features:Cosmic Growth System: Evolve from an asteroid to a planet, a star, and finally a black hole, each stage offering unique gameplay and abilities.Realistic Physics Simulation: Experience lifelike gravity and orbital mechanics—construct stable planetary systems or trigger spectacular collisions and chaos.Dynamic Sandbox Universe: An ever-evolving universe where new celestial bodies and events continually emerge, and cosmic evolution never stops.Explore the Binary Black Holes: As the binary black holes grow and spiral toward each other, will you survive—or be swallowed by the void?
