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!

The light from a star expands in a sphere, We see it as a point source because its angular size in the sky is smaller than the details our eyes can resolve. The light isn’t exactly in formation, it’s just going everywhere, but it’s all coming from the same place.
