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

None knows if light experience time or not. It’s pure speculation.
What we know is that as you approach the speed of casuality(which is speed of light), everything around you speeds up, you basically go through years in seconds.
If you take those same equations and put your speed as the same of speed of light, then you get something that doesn’t even make sense, you have to divide by zero. So yeah it doesn’t really make sense to even think of time for a massless object like light.
