This concept extends to the furthest reaches of space; looking at distant stars means viewing them as they were years or millennia in the past. The time for light to reach Earth from the sun is not an instantaneous blink but a measurable interval of approximately 8 minutes and 20 seconds.
Astronomers Measure Sunlight Travel Time First: How We Pinpointed the Sunlight Travel Time
GPS satellites must account for relativistic effects and the precise timing of signals, including the time it takes for data to travel from the satellite to your device. This value is not a guess but a defined constant used in celestial mechanics.
Light travels in a vacuum at a constant speed of roughly 299,792 kilometers per second. 1 million km 8 minutes 13 seconds Average Distance 149.
