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

696 views

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

Your calculation for 2 hours makes me laugh and I see what mistake was made. It would be 1340 not 1214.
