Cosmic Scale & Real-World Examples

While the speed of light feels instantaneous in our daily lives, the vastness of space reveals its limitations.

Around the Earth: Light can travel around the Earth's equator roughly 7.5 times in a single second.
Earth to Moon: It takes light about 1.3 seconds to cross the gap between the Earth and the Moon.
Sun to Earth: Sunlight takes approximately 8 minutes and 20 seconds to reach us. If the sun suddenly went dark, we wouldn't know for over eight minutes.
To the Edge of the Solar System: Sunlight takes about 4 hours to reach Neptune.
