Real-Time 3D Interactive Galaxy Simulation | HTML5 Canvas, CSS3 Animations & JavaScript ES6

🌟 **Unlock the Secrets of the Cosmos with Code!** 🌌
In this **cutting-edge tutorial**, you’ll learn how to build a **real-time 3D interactive galaxy simulation** from scratch using **HTML5 Canvas, CSS3 animations, and modern JavaScript (ES6)**. Perfect for developers, astrophysics hobbyists, or anyone passionate about merging science with creative coding!

### 🚀 **What You’ll Build**
- **Procedurally generated 3D galaxy** with dynamic particle systems.
- **Newtonian gravity simulations** for realistic stellar motion and orbital mechanics.
- **Particle physics visualization** (mass, velocity, collisions) using vector math.
- **Cinematic visual effects**: star trails, redshift/blueshift gradients, and depth-of-field blur.
- **Interactive UI controls** (zoom, rotation, speed sliders) with CSS3 animations.
- **Performance optimization** for smooth 60 FPS rendering (Web Workers, requestAnimationFrame).
