Galaxy Simulation

🌌 Galaxy Simulation 🚀

I developed an interactive simulation of a multi-body gravitational system. Despite its name, Galaxy Simulation, the project is not a literal galaxy model but rather a general N-body system governed solely by Newtonian gravity, with configurable initial velocities. The bodies are arranged in concentric, circular layers.

🪐 Users can experiment with key physical parameters such as:

• ⚖️ Gravitational constant

• 🌍 Central mass (default: very large, acting as a dominant attractor or "black hole", but can be adjusted)

• 🌟 Number of initial bodies

• 📏 Layer density

• 💨 Initial velocity

• 🔧 Epsilon (softening distance)

• ⏱️ Δt (time step)

✨ Dynamic features:

• Expand or compress layers

• Add or remove bodies at runtime

• Return anytime to the settings screen

• Real-time visualization of kinetic, potential, and angular momentum

• In the two-galaxy mode, you can drag and reposition galaxy centers live, creating intergalactic interactions

🌠 The result is a versatile platform for exploring celestial mechanics and emergent behaviors of gravitational systems — from simple two-body motion to complex galaxy-like structures.

📚 Educational value:
This simulation offers physics educators and learners a hands-on tool to illustrate:

• Orbital motion

• Conservation laws

• The role of initial conditions in system evolution

By letting users manipulate parameters and instantly see the outcomes, the simulation helps bridge the gap between abstract equations and physical intuition.
