That’s kind of the wrong question. I’m not exactly sure how to ask because I don’t know where I’m confused.
This morning, sitting under the stars for 2 hours before sunrise, I pondered the old light of stars.I had never thought about the journey light had to travel and retain its form. I don’t understand how we see the source as a pin prick of light from that distance… and someone standing right next to you (or half way across the earth) would see the same pin prick but it would be different photons hitting their retinas.
How does the light spread like that but retain any form? If photons move perceptibly (to our measuring equipment) in close distances in the double slit experiment, how do they stay in a tight enough formation over those vast distances to still look like a pin prick when they reach us. I’m not sure I’m asking the right question but I found my mind a little boggled by what is probably a simple to explain phenomenon that shouldn’t even be confusing. Probably a couple questions in there.
Thanks!

Draw two dots on a page. One represents a star and the other your eyeball. Now draw a bunch of straight lines radiating out from the star representing light beams, including one going straight towards your eye. The only beam you can see is the one that reaches your eye and that come from exactly the direction of the star. So you see the star in only one location, making it a tiny dot. For it to seem blurry (assuming your good vision) some light would have to come from a slightly different direction.
