If the sun instantly switched off like a light bulbwhich cant happen, by the waythen we wouldnt know for almost 8 and a half minutes. Light travels at the fastest speed there is, but it still takes almost 500 seconds to get to Earth. Thats how long it would take before we knew the sun went dark.But the most amazing thing about the sunlight we see is its actually really old. SUPER old. AMAZINGLY OLD! Tens of thousands of years old. How is that possible? Because of the physics and mathematics of random walks.
