Here's why:

* The speed of light: Light travels at a speed of approximately 299,792,458 meters per second (186,282 miles per second).

* Distance from the Sun to Earth: The average distance from the Sun to Earth is about 149.6 million kilometers (93 million miles).

To calculate the travel time:

* Time = Distance / Speed

* Time = 149.6 million kilometers / 299,792,458 meters per second

* Time ≈ 500 seconds ≈ 8 minutes and 20 seconds
