Question

How long does it take the sun's light to reach earth?
Asked by: CITO GASTON

Answer

The distance from the Earth to the Sun varies because the Earth's orbit about the Sun is elliptical.At it's closest, the distance is 91,402,000 miles and it's farthest distance it is 94,512,000 miles.This gives an average distance of 92,957,000 miles. Light travels at 186,282 miles per second. Dividing the average distance by the speed of light gives 499.01225 seconds which is 8.3168708 minutes.

Rounded off, let's say 8 minutes and 18 seconds.

Science Quote

'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
