Logic-Flow Educational Puzzle

Game Concept: An educational game where students link historical events (Chronos) using "Energy Threads." It uses a force-directed layout to keep event bubbles floating naturally in a 3D space.
Technical Prompt:
Create a link-based puzzle. Use a force-simulation logic to prevent bubble overlapping. When two correct bubbles are clicked, draw a CatmullRomCurve3 between them with a glowing neon texture.

游戏概念：一款教育类游戏，学生通过“能量线”连接历史事件（Chronos）。使用受力模拟布局，使事件气泡在 3D 空间中自然漂浮。  
技术提示：  
创建一个基于链接的谜题。使用受力模拟逻辑防止气泡重叠。当两个正确的气泡被点击时，在它们之间绘制一条 CatmullRomCurve3，并赋予发光的霓虹纹理。
