#31 We Will Have 8 Minutes to Live If the Sun Exploded Now
Light takes 8 minutes and 20 seconds to travel from the sun to the earth. So if the sun exploded right about now, we would not know it until 8 minutes and 20 seconds.
However, this isn’t something you should fret about. It’s been 5 billion years or so, since the sun is burning, and it won’t change for another 5 billion years. In case it did explode, you’d still have some time on hands to finish all your pending work! Just saying!
