This is just the law of really big numbers.
Something literally astronomical relative to something subatomic is necessarily going to happen.
A Star is really really big but more importantly it produces a more than a lot of photon’s
Its not light years, but approximately 8 light minutes.
The light is not from our sun, but another star. Its nighttime for the cow.
Bulls on farms rarely stick around for 20 years. Also, how did it account for 20yrs of movement of an unpredictable life form?
You have a point, buuut: photons don’t experience time or distance. Leaving the star and hitting the bull’s eye happen in the same instant for them, no matter how many billions of light years apart they are. From the point of view of the photon, the bull’s eye is touching that star in that other galaxy. For just that single instant in time.
I am so glad others have this thought. I look at stars and realize that particular particle hit my eye from that far away.
It seems very sure that it’s a light particle… I like those vibes.
