Amateur. In a dark location, on a clear night, I can see the Andromeda Galaxy, 2.3 million light years away.

Oh yeah, well I can see your mom. 2.3 million light years away. Because she's fat.
How fat is she?
She's so fat that I'm genuinely concerned for her health.
Shes so fat im concerned for the higgs fields' health
💖
Just fat enough 😋
I suppose we can calculate a minimum, if we look up the smallest angle of resolution for human eyes, and approximate her as spherical.
She's so fat that we're worried her and the sun will form a binary star system.

You can't see my mom, she's dead.
She's 2.3 million light years away. We're seeing her in the past.
Of course she's dead, she's in space...
Fuckin' got them! Nice.
Triangulum Galaxy is a smidge farther away (~2.7Mly) and also naked eye visible with the right sky conditions and good eyes.

But since the sun is 93 millions miles away it's further because the number is bigger

Smh you say on a dark place but then you say light years. If the whole year is light then how do you expect anyone to see if it has to be dark?

I think you a word
Must be hard to can the sun. Shit’s hot and really big.
Neptune: tf are you talking about
The Oort Cloud: lolwut
Interstellar medium: fuck me, it’s cold
Sagittarius A*: (chuckles softly)
Andromeda Galaxy: tf is a sun
Laniakea Supercluster: yo is that the Hercules–Corona Borealis Great Wall?? What up, homie!
Universe: gotta go fast
Can:
Me who can see Polaris 433 light years away.
who can the sun 93 million miles away
I can the sun 93 million miles away
Look at the sun for a while and you won't see anything ever anymore.
Everest can be seen 200 miles away on a clear day
It's 90 miles from Seattle to Mount Ranier and it absolutely dominates the horizon.
Where did you learn that? Is that a real thing people are taught?
3 miles is roughly how far you can see to the horizon (before the curvature of the earth blocks your line of sight)
I don't want to check miles, but it's pretty on point with what I remember, which is the horizon being 5km away for a 180cm (~6ft) tall person. (3 miles is close enough to 5km)
Getting even a few meters of something under you would drastically change how far you see.
A few extra meters wouldn't be too drastic. From the top of Everest the horizon is about 300km away.
1.8 meters sees ~4.8km. Standing on top of a car, on someone else's shoulders, at say, 5 meters, would give you eight kilometers.
Granted, not too drastic yeah. But like, if you have a tree, and climb it, and it's, say, 15 meters. Now you can see ~14 kilometers.
I'd say going from ~5 to ~14 by climbing a tree (or a mast of a ship) is pretty significant, but not drastic, I'd agree to that, yeah.
I wonder how much it was an advantage at sea, really. Like the scout at the top of your mast would be able to see the enemy ship from very far, while the enemies would technically be able to see only the mast of the ship that the scout is on, making it much harder to spot. I'm sure someone's written about it in tedious length. An upvote to anyone who finds me such texts.

Just googled it now, and I'm seeing the "3 miles" number thrown around a lot.
That's just weird. The question is about the eye. And the primary "answer" they give is about the geometry of our planet.
Edit: At least the real answer is somewhere further down in the text:
Theoretically, in a vacuum there's no limit to how far away your eyes could see since light rays can travel an infinite distance, McCulley says.
Light emitted farther than 46 billion light years away will never reach you. While traveling an infinite distance the universe expands faster, and light emitted not that far will get so red-shifted that it won't be visible anymore.
Flat earth proven! Boom! /s
I don't think you needed a /s for that
Poe's law would say otherwise.
Yes, but for how long?
Teacher: not anymore
tbf, looking at the sun from three miles away would be all that you could see.
Y’know, if it didn’t instantly turn you into plasma.
To be fair, Sun is a source of light. Moon, on the other hand...
