What If the Sun Disappeared Timer
See how long it would take before sunlight and gravity effects from the Sun stopped reaching Earth.
Result
Time until sunlight vanishes

Comparison
Fun physics thought experiment only. In relativity, both light and changes in gravity propagate at the speed of light.
How we calculate
Time = distance ÷ speed of light. We convert AU to kilometers, then calculate how long light takes to travel that distance.
