Me who can see Polaris 433 light years away.
V762 Cassiopeiae: am I a joke to you?
I can the universe 40b light-years
Oh yeah? Well I can see colors!
Look at the sun for a while and you won’t see anything ever anymore.
Yes, but for how long?
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.
You can’t see my mom, she’s dead.
Of course she’s dead, she’s in space…
She’s 2.3 million light years away. We’re seeing her in the past.
How fat is she?
She’s so fat that we’re worried her and the sun will form a binary star system.
She’s so fat that I’m genuinely concerned for her health.
Shes so fat im concerned for the higgs fields’ health
💖
I suppose we can calculate a minimum, if we look up the smallest angle of resolution for human eyes, and approximate her as spherical.
Just fat enough 😋
Pretty fat yo
Well, fat at least
Triangulum Galaxy is a smidge farther away (~2.7Mly) and also naked eye visible with the right sky conditions and good eyes.
Looks like a smudge until you unfocus your eyes anyway.
I think you a word
You can’t the whole sun.
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:
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.
Well, there’s a reason old ships had people high up as scouts. These days we just use radar and gps
did you just not read the last paragraph??
I mean yes, that’s obviously the purpose. I just wonder how effective it was, and would like to read about it.
Depends how high you are. On a tower you can see much further.
Depends on whether it’s a tall tower or a tiny tower.
It depends on the family drama. You might get pulled away before you can look
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.
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.
who can the sun 93 million miles away
I can the sun 93 million miles away
No you can
Yes we can
Can you Son?
Teacher: not anymore
