This is the "time travel" aspect of astronomy that I find extremely fascinating.
I was just talking to my young sons the other day as we were watching the sunset that we are seeing something that happened 8 minutes ago. Cool to see them trying to get their young brains around this concept...
- daveguy 10y agoThe sunset you were seeing didn't happen 8 minutes ago. Sunsets are an interaction of the sun with your perspective position on earth and line of sight. The sunset was happening right then -- the light that was involved in the sunset had been emitted from the sun 8 minutes ago. The last blip of the light you saw disappear over the horizon was a view of a corner of the sun from 8 minutes ago, but the sunset was happening essentially at that moment. </pedantic>
