中文导读
Cody's Lab 按两千亿分之一的比例搭建了一个物理模型，结合视差现象与光速概念，直观呈现离地球最近的恒星究竟有多遥远。短小精悍且极具冲击力的星际尺度科普。
为什么 HN 推它
每当讨论需要打破思维局限、建立对恒星间广袤虚空的真实感知时，网友们总会掏出这个实物演示来做直观印证。
「不妨看看这个视频，它仅仅是把最近那颗恒星的距离具象化出来，就足够让人震撼了，更别说更远的地方了。」HN 网友原话：maybe watch this video that illustrates the distance only to the closest star, let alone any further away
英文原摘要（HackerTube / Claude 整理）
Cody's Lab builds a 200-billionth-scale model to show how far away the nearest stars are, using parallax and light speed. A short astronomy explainer on interstellar distances.
Recommended whenever threads need an intuition for the vast distances between stars.

Here's a fun video that explains
There are many youtube videos that try to visualize the incomprehensible scale of space.
Cody put a few solar system objects on a stadium, with distances to scale, the sun is represented by a pea.
Here's a great video to illustrate
