Can't let you go thinking you're right!U is located at the apex of a light cone representing a personal perception space. His timeline is the cone axis extending downward from zero, the apex, into negative time units. An x-y plane is centered on the apex. U considers himself at rest. An object e is moving past U in the x direction offset a distance d. The path of e is projected onto the light cone forming a hyperbola. If e is moving right to left, it is approaching from the past to its closest approach, then receding into the past (noyt the future). If e was moving left to right, it is still approaching from the past. So where is the future, typically shown as a light cone reflected in the x-y plane. If e moved from the past to the future, how would it cross the gap from one cone to the other? When a distant event is observed, it's labeled as historical. The problem is, there are two types of events. A photon lifespan begins with emission and ends with detection. This establishes an order, detection must follow emission. The time of perception or awareness of an event is the present. The time of an event is in the past, and requires additional information such as distance. U has no future light cone since he cannot perceive events beyond the present. The same distance determines how much time until perception of the event, and how much time since the event occurred in the past.
I have no idea how to even try to relate that to what I posted.
You do not see a distance planet in the past, you see it in the present

You seem to find yourself in that position quite frequently Mr. Box.Quote from: Thebox You do not see a distance planet in the past, you see it in the present Light takes time to reach your eye Mr. Box so we see distant objects as they were in "their past" even though we receive that belated image in our present.
Then I accuse you of not reading correctly or not understanding the topic.

You can accuse me of not reading correctly to which I answer: "I have read and understand your confusion Mr. Box." And you can also assume that I don't understand to which I also answer: "I along with many others here at TNS understand you Mr. Box." And the understanding that we have is this: "You are seriously confused Mr. Box and resist listening to reasonable people and to the results of professional experiment."And, if I were you, I would think twice before accusing anyone here about their ignorance of the spoken word or, in understanding the prime example of a very confused individual.
the boxEthos is saying the image of the sun takes ~8 seconds to reach earth. Another way to understand it is say we can blink out the sun. It would take ~8 seconds for the image to blink out on the Earth. Or it could blink on and it would take ~8 seconds to view the light. You confuse clear glass as seeing with the infinite speed of light. The image reaches your eyes and your eyes do not reach the image as you currently believe. No wonder you do not believe relativity.
