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

[–] [email protected] 76 points 2 months ago (3 children)

Oh yeah, well I can see your mom. 2.3 million light years away. Because she's fat.

She's so fat that I'm genuinely concerned for her health.

She’s so fat I can see what’s behind her

[–] [email protected] 4 points 2 months ago

She's so fat that observers are really mostly seeing what she used to look like.

I suppose we can calculate a minimum, if we look up the smallest angle of resolution for human eyes, and approximate her as spherical.

[–] [email protected] 7 points 2 months ago

Just fat enough 😋

[–] ZoopZeZoop 6 points 2 months ago

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.

[–] [email protected] 22 points 2 months ago

She's 2.3 million light years away. We're seeing her in the past.

[–] Crashumbc 9 points 2 months ago

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?

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

[–] [email protected] 8 points 2 months ago

It's 90 miles from Seattle to Mount Ranier and it absolutely dominates the horizon.

[–] warbond 21 points 2 months ago (4 children)

Where did you learn that? Is that a real thing people are taught?

[–] [email protected] 58 points 2 months ago (7 children)

3 miles is roughly how far you can see to the horizon (before the curvature of the earth blocks your line of sight)

[–] Dasus 18 points 2 months ago (1 children)

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.

[–] [email protected] 4 points 2 months ago (1 children)

A few extra meters wouldn't be too drastic. From the top of Everest the horizon is about 300km away.

[–] Dasus 19 points 2 months ago (3 children)

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.

I don't think you needed a /s for that

Poe's law would say otherwise.

[–] Zachariah 13 points 2 months ago

Yes, but for how long?

Teacher: not anymore

[–] [email protected] 6 points 2 months ago

To be fair, Sun is a source of light. Moon, on the other hand...

[–] [email protected] 6 points 2 months ago

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.
