Do photons experience time?

In relativity theory, fast moving clocks tick more slowly than slow moving ones. The effect increases as one approaches the speed of light. But what happens at the speed of light? Do photons experience time? In this video, Fermilab’s Dr. Don Lincoln lays out what we know about this interesting question.
