Eli5: How can light not experience the passage of time if it travels at 670 million MPH – a measurement of time (and space)

Question

If light travels at 670 million miles per hour, then that means in one hour it will travel 670 million miles. At 2 hours it will travel 1214 million miles etc. This to me sounds like a measurement of time, just on such a huge scale that we can’t comprehend it. But in the grand scheme of the cosmos this is not that crazy of a scale. I would think it’s just saying light doesn’t experience time *relative* to us. But Einstein says no- no matter what, light’s speed doesn’t change and, what, relativity just doesn’t matter? It feels like a paradox

Answer 1

In one hour it will travel 670 million miles *from your perspective*. Time is relative. For you, it takes an hour for the photon to travel 670 million miles, but from the photon’s perspective it’s instant. And this is because the faster something travels, the more spacetime contracts.
