001 / INFINITE QUESTIONS
If the Sun vanished right now, when would Earth notice?
It looks close in the sky. But light has a long way to travel from the Sun to Earth.
About 8 minutes and 20 seconds.
Light travels roughly 300,000 kilometres every second. At Earth's average distance of 149.6 million kilometres, sunlight takes about 499 seconds to reach us. That's why we're always seeing the Sun as it was a little over eight minutes ago.
