I have a question for you all. I asked my Physics teacher this in school not so long ago. I made an animation of it on a little art thing (which rocks btw, I suggest you all use it for your examples or theoreys) http://artpad.art.com/gallery/?idilmbnxbps [Broken] In a nut shell: You're on a perfectly flat earth. The sun is rising What do you see first? The planet being illuminated by the light? or The source of light? (Sun) Since light travels faster than anything, as it is an energy, theoretically wouldnt you see it first? But since the object, being the Sun in this case, is not an energy, it does not take time to travel, but instead needs to be bright enough (Think back to light hitting you) or close enough for your eye to recieve. Since it's not close enough for your eyes to recieve it as soon as you look at its heading, you must see the light first, which in turn, is the initial Sun itself. My question? Do we see the Sun first? The light first? Or both at the same time. EDIT: In my animation, I made a horrid mistake. I blanked out, and forgot the Sun was a star, thus it's a ball of gas, not lava. :rofl: My bad. Forgive me?
