If the Sun Disappeared Right Now, This Would Happen in 8 Minutes | Leonard Susskind

If the Sun suddenly vanished, would Earth instantly freeze? Would gravity disappear immediately? Would we be thrown into deep space? The answer is more surprising — and more precise — than most people expect. In this video, we explore what modern physics says would actually happen if the Sun disappeared right now. Drawing on ideas associated with Leonard Susskind and Einstein’s theory of relativity, this documentary examines how information, gravity, and light propagate through spacetime. Light from the Sun takes approximately eight minutes to reach Earth. That means every time you look at the Sun, you are seeing it as it was eight minutes ago. But the delay is not just about light. According to general relativity, changes in gravity also propagate at the speed of light. If the Sun were to vanish, Earth would continue orbiting normally for about eight minutes. The sky would look unchanged. Daylight would continue. Only when the last photons — and the last gravitational information — reached us would we experience darkness and orbital collapse. This reveals something deeper about the structure of reality. There is no universal “now” connecting distant objects. We do not observe reality in real time. We interact with past light cones — historical information carried at finite speed. The universe enforces locality. No signal, no influence, no causal change can move faster than light. Not even gravity escapes this rule. This video explains why the speed of light is not just a limit — it is the architecture of spacetime itself. It defines causality, structure, and the way reality unfolds. The Sun you see is always eight minutes old. And nothing in the universe happens instantly at a distance.
