Universe Sandbox

Universe Sandbox is a physics-based simulation that allows users to model, observe, and interact with astronomical systems. The program focuses on gravitational forces, planetary motion, and large-scale cosmic events. Players can create their own solar systems, modify existing ones, or recreate real astronomical events using adjustable parameters. The goal is to experiment with physics and observe how small changes in mass, velocity, or position affect entire celestial systems.

Simulation and Core Mechanics

Universe Sandbox provides tools that replicate real physical laws to simulate planetary interactions in real time. The user can manipulate individual objects or entire systems to observe the results. Each object reacts to others based on gravity, velocity, and collision. The primary mechanics include:

•         Creating planets, moons, and stars with adjustable mass and density
•         Colliding celestial bodies to observe outcomes and debris formation
•         Modifying temperature, atmosphere, and rotation speed
•         Scaling time to view long-term orbital evolution
  These tools transform theoretical physics into visual models, letting users understand motion, stability, and energy transfer in space.

Experimentation and Data Integration

The program includes real astronomical data from NASA and other scientific sources. Users can load accurate models of the Solar System, exoplanets, or galaxies and modify them according to custom scenarios. This feature makes Universe Sandbox useful for both education and personal experimentation. By adjusting factors such as orbital distance or mass, users can study how stars evolve or how planetary systems collapse under extreme conditions. Each simulation remains interactive, allowing constant adjustments and observation.

Educational and Creative Applications

Universe Sandbox serves both as a learning tool and as a platform for creative expression. Teachers and students can use it to visualize gravitational relationships or explain celestial events. Hobbyists can design fictional star systems or test hypothetical collisions between planets. The program also supports importing external models and exporting screenshots or videos for presentations. Because all processes follow real physics, it provides an accessible way to understand complex astronomical concepts through direct interaction.
