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

Time is a concept, light is a type of matter. We’re rotating on the Earth’s axis at 1,000 mph, orbiting the sun at 67,000 mph, and spiraling around in the Milky Way galaxy as it all collectively makes its way towards Andromeda at about 1.3 million miles per hour within the known universe. I would imagine light can’t experience time in approximately the same way we don’t sense all of the aforementioned items. It is humbling and awe-inspiring though! Also, mildly terrifying. Beware the lurking comet of doom, or quasars, or a banana peel.
