Why You Can Never Leave the Milky Way

The Milky Way isn't holding us in with walls or force. It's doing something quieter than that — it's holding us in with geometry. With mass. With physics that was already running before the Earth existed. This video sits with that idea for a few hours, moving through escape velocity, dark matter, the merger with Andromeda, and what happens when the last star finally goes out. Long-form, slow, made for night.
