That warmth on your face? It left the Sun before your coffee brewed.
That warmth on your face left the Sun before your coffee brewed. Light travels about 300,000 kilometres every single second — the fastest anything in the universe can move — and it still takes around eight minutes and twenty seconds to close the gap between the Sun and your skin. The Sun sits roughly 150 million kilometres away. So every ray of sunlight you've ever felt was already ancient the moment it touched you. Step into the next thought: if the Sun were to vanish right now, Earth would carry on in full daylight for more than eight minutes before the truth caught up. And Proxima Centauri, our nearest stellar neighbour, sends light that travels for over four years before anyone here notices it. Space doesn't care how fast light is.
