To put this in #tardstr speak, (and why this is insanely fascinating)

Think of light as a weightless messenger that carries energy without any baggage. Since it has no mass, it doesn't need to slow down or speed up. It's like a programmed message that travels endlessly until it's received or absorbed.

Remember, when we talk about the universe, we often see what's happening but don't always understand the deeper "why" behind it. We're excellent at observing things, but sometimes the true understanding might still be beyond our reach. nostr:note1g0up9c4qe276v4n8488e2epptea3cnky9p0xp07jm9z3y27wr0xss0cfc5
