SUMMARY
Einstein's theory of Special Relativity establishes that time is effectively 'frozen' for light and that space is infinitely contracted for light, meaning light does not experience time or distance. Observers traveling at near-light speeds will always measure light traveling at the speed of light, regardless of their own speed. Additionally, no material object can reach the speed of light due to the infinite energy requirement. The travel time of light from distant stars is measured in lightyears, indicating the duration it takes for light to reach Earth.
