Someone's lying

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?
  
  You can't see my mom, she's dead.
  
  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.
  
  Looks like a smudge until you unfocus your eyes anyway.
  
  I dont think 400000 times light can travel in a year of difference is "slightly further away"
- But since the sun is 93 millions miles away it's further because the number is bigger
  
  No you see some infinites are bigger than other. So light year is basically a larger infinity than millions. There's a YouTube video about, look it up 👍
  
  /s (you never know these days)
- 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?
  
  It's a timey-whimey thing.
- You're not really seeing it, though, your seeing it's distant past
  
  If you're going down that road, you're never seeing anything in its present form because even for an object a meter in front of you, all you're really seeing is the object as it existed nano seconds in the past. Hows is a nano second in the past different from years in the past?
Me who can see Polaris 433 light years away.
- V762 Cassiopeiae: am I a joke to you?
  
  I mean I can't pick it out of a starfield or navigate the ocean at night by it. So. Ya.
- I can the universe 40b light-years
  
  Oh yeah? Well I can see colors!
  
  No, billions of lightyears is the realm of telescopes.
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:
- You can't the whole sun.
  
  Is that dangerous?
who can the sun 93 million miles away
- I can the sun 93 million miles away
  
  No you can
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.
  
  Depends how high you are. On a tower you can see much further.
- 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.
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
To be fair, Sun is a source of light. Moon, on the other hand...
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.
aw look, junior made a meme
Whats upto
- It's how far you can the sun.
- Nvm looked it up, it's like updog
