Now That's FastTake one second. Now divide it into 299,792 equal segments. Got it? That's how long it takes light to travel one kilometer (in a vacuum). Now that's fast. And yet it still takes a ray of sunshine a little over 8 minutes to travel from the Sun to the Earth. That because the Sun is a whopping 93 million miles away. That just boggles my mind--that something can seem so big and blinding in the sky can be that far away. That must one heck of a ball of fire for us to see it this far away.
