/sci/ - Science & Math

>>11438519
Wow that is incredible, it is true. Never tell this to anyone or they will Epstein you.

I dont believe you, take pics

Yes. Its flat.

Modern science is a religion and NASA is god.

No coincidence, it's all jewish.

>>11438533
OK, I should be back in like 30 minutes
I'm also making lunch right now though, so don't be surprised if it takes a little longer

>>11438550
Actually before I go, is there an image size limit on /sci/ or anything like that?

>>11438533
Okay here you go:

>>11438606
I used the HV pylons as a guide because I could see them with the naked eye and the horizon seemed to run through them

>>11438606
Im not going to argue with you. I haven't and I wont read the OP. I just wanted to waste your time. Get fucked.

>>11438614
Here is the reading corresponding to the view in my previous image, as you can see it is bang on 0.

>>11438615
I'm not looking for an argument, I'm looking for a scientific explanation of these pictures.

>>11438622
The explanation is that the horizon is very, very far away in comparison to the distance of the telescope off the ground. Do you know trigonometry? Then you know that the angle between your telescope mount and the ground is arctan(some very large number)=90 degrees. That's why its level.

>>11438631
So are you saying I need to be higher up to observe this drop? I was already on a hill, how much higher do I need to be? (the pylons are about 6km away if that matters)

>>11438644
>how much higher do I need to be?
Trig. Do it.

>>11438644
>how much higher do I need to be?

try an aircraft, you should be able to see a fairly notable curve with out any extra lenses and whatnot, just with your eyes

>>11438655
Fuck maths, I'm trying to do this with as little effort as possible.
>>11438662
would the higher floors of a skyscraper do? planes are expensive and their windows are too tiny for me to try it there.

>>11438669
>would the higher floors of a skyscraper do?
No. If you were in a skyscraper 1 mile high, the distance of the horizon/height of the building would still be a large number. You need to be many miles high. If elementary trigonometry is too advanced for you, consider giving up.

>>11438669
Don't be discouraged, >>11438672 is somewhat telling the truth, but if you look hard enough you will notice the curve.
I remember going to the top floor of the Caribe Hilton in San Juan (not an extremely tall building) and clearly seeing the curvature of the earth. The effect is more pronounced over the ocean, so try to find a coastal building.

>>11438712
I'm not looking for the curvature as such (I've seen that plenty of times) but specifically for the horizon to appear below the centre of my vision, as I mentioned in the OP, or alternatively, a reason why this would not be the case, like >>11438631 so helpfully provided.
If I go to a skyscraper I can take my level rider and some binoculars and repeat the same experiment there, but if that's still not high enough then I guess I'm out of options.

>>11438519
>an observer looking straight ahead at 90 degrees to the pull of gravity should be looking above the horizon, with their view heading off tangentially with the surface of the earth, like in pic related.

How far above? Do the math and figure out how far below level the horizon should be. Is the predicted answer less than 1 degree?

>>11438519
>why is this the case.
Scale, you retarded nigger

>>11438614
Go to ocean and do it again. Thats a fucking mountain

>>11438519
>No matter how many times I did this, or which of the visible horizons I looked at, the reading on the level rider was always within 1 degree of 0.
>always within 1 degree of 0.
Well the average land elevation is around 800m (Don't know your elevation) so at that elevation the horizon drop would be around 1 degree.

>>11439717
What's the scale of that pic?

>>11439788
1/6371000

>>11439788
>>11439804
So how big is one of those little grey squares?

The earth is round u monkey

>>11439971
>So how big is one of those little grey squares?
This one? 0.02*6371000 = 127420 meters.
The smallest one would be 127420/5 = 25484 meters.
I placed the observer at an height of 800 meters above the circle (Earth).

>>11438519
If you do the experiment in a plane at a cruising altitude of 35000 feet, the horizon drop would be 3.2 degrees. At 3 feet above sea level it would be 0.03 degrees.

Horizon drop = 90 - arcsin(r/(r+h))
r = earth radius
h = height above sea level

This is a picture of an internet someone's basketball experiment. I showed my flathead friend something similar with a ball, flashlight, and a dark room and told him to imagine he was an ant on the ball. It doesn't even make a difference if the ant gains considerable altitude in a rocket because you are gaining altitude perpendicular to your point of view. Not so good with explanation but take your imagination, ball, light to a dark room.

>>11438615
dont act like you didnt read the OP and got btfo

>>11438615
Ah yes, what a great scientific mind, shying away from a challenge using a false air of supremacy to cover his ignorance and cowardice.
Your ilk are why so few respect modern science.
