No actually EVERYTHING, at ANY distance, that we see happened the past whether it’s 186,000 miles away (appears one second in the past) 93,000 miles away (half a second in the past) or right in front of our faces (infinitesimal fraction of a second in the past.) ANY object we “see” is because light traveled from somewhere and it took some amount of time to travel to our retina and what our brain tells us we see happened at some time in the past, whether the duration is unbelievably small and recent like the image you’re reading on your monitor or billions of years in the past like some of the stars you see when you peer into the night sky.

I was just clarifying for others what you said about some objects appearing as they were “fractions of a second ago”. These objects would obviously have to be within 186,000 miles for the light to take less than a second to reach us (light of course travels at 186,000 miles per sec). I understand they could be within 2 or 3 feet, or 2 or 3 inches. I’m not so sure what happens at the level of atomic particles though. Quantum reality is extremely weird.

If you wanna get all accurate about it, many of these objects never actually existed as pictured. Since they are likely very large, the period of time it takes for the image to get here would be different for various parts of the image. In other words, pixel A could be seconds, minutes, days or more older than pixel B.
