开端：旅行到宇宙边缘
Prologue: Journey to the Edge
一切始于小学四年级。那个夏天，我在纪录片频道偶然点开了《旅行到宇宙边缘》。当镜头穿越土星环、掠过木星大红斑、最终在宇宙微波背景辐射前停下时，我的世界被彻底改变了。
我开始追问那些没有答案的问题：宇宙之外是什么？时间有起点吗？暗物质到底是什么？这些疑问像种子一样在心里生根发芽。
It all began in fourth grade. One summer, I stumbled upon the documentary Journey to the Edge of the Universe. As the camera glided through Saturn's rings, past Jupiter's Great Red Spot, and finally paused before the cosmic microwave background, my world was irrevocably altered.
I started asking the unanswerable: What lies beyond the universe? Does time have a beginning? What exactly is dark matter? These questions took root like seeds in my mind.
