If you zoom you're zooming in the direction you're pointing

2019-04-20 09:50:40 UTC  

Such light cannot be bend by earth.

2019-04-20 09:51:35 UTC  

Exactly

2019-04-20 09:52:37 UTC  

That's their standard refraction model for 123 miles

Well the blue is the earth. The red is the path light takes in their standard refraction model
So anything on the earth at the blue will be elevated to the red
by refraction
So that is the standard 7/6 R

If your at 1000 miles altitude I guess you can see the other side lol

Here's the thing. Actual experiments show refraction varies from 20X to - 20X

On the other hand, our empirical results show that the
refraction coefficient k may reach magnitudes as large as +12 to +16 over grassland at 1.8 m. This clearly
exceeds previously published ‘extreme values’ (e.g., maximum values of k = +6 at 1.5 m height over grassland,
cf. Hübner [1977]). We acknowledge that surface types like ice or water may even produce larger refraction
effects, as described in section 2.

As you can see from what I just posted , they measured what would be radius that would be 16 times larger than the earth radius
They think k they model refraction ,.In fact they model the deviation from from the globe radius.
They don't measure the refractive index of the air. the impute it from the deviation of an expected value
of course. Their model follows earths curve perfectly
think about how nonsensical that is. exactly equals the curve of the earth...idiocy...

I see the moon

*In conditions that produce superior mirages, there are inversion layers in which the ray curvature exceeds that of the Earth. Then, in principle, you can see infinitely far — there really is no horizon.
Of course, we all know that visibility is limited by the clarity or haziness of the air. And the duct that (in principle) might allow you to see around the whole Earth doesn't really extend that far; it typically exists for some limited region, perhaps a few tens or a few hundreds of kilometers.*

The 7/6R is acknowledged to be a mere *assumption*
Remember that this "standard atmospheric refraction" is not the same as typical refraction you get with Snell's law, this is ad hoc reification.
You don't need to take into account anyones hypothetical in your experiments, they have to empirically derived it by experimentation, onus is on them.

hey guys

2019-04-20 15:20:02 UTC  

@Citizen Z image text is wrong, can't see the bottom of the mountains

2019-04-20 15:20:06 UTC  

THus we can throw that one out

2019-04-20 15:21:27 UTC  

their are so many places we see farther than we should

2019-04-20 15:22:04 UTC  

and now they are using infra red and seeing even farther

2019-04-20 15:45:05 UTC  

@Frolic never said bottom. Said bases

2019-04-20 15:45:31 UTC  

Your mind must have made that up

2019-04-20 15:53:43 UTC  

How do we know the observer height there?
That can be tricky, as google earth is often inaccurate, and we often don't have the means and data to determine it

2019-04-20 17:32:23 UTC  

you don't poop out your poop hole

2019-04-20 18:10:46 UTC  

first of all what is the curvature formula for earth ?

2019-04-20 18:11:00 UTC  

are we using 8 inches per mile squared

2019-04-20 18:11:52 UTC  

o

2019-04-20 18:11:56 UTC  

im not a mathmetician but i dont think thats a good number or formula

2019-04-20 18:13:04 UTC  

lets say its 8 inches for now ill show u how the formula is wrong maybe

2019-04-20 18:13:37 UTC  

4 people in a straight line all 1 mile apart man a man b man c man d all in a row in that order

2019-04-20 18:15:57 UTC  

the curve drop from man a to b is 8 inches and the man from b to c is 8 inches but from a to c should be 16 inches

2019-04-20 18:17:29 UTC  

but a to c is 32 inches

2019-04-20 18:19:43 UTC  

ok

2019-04-20 18:19:55 UTC  

ok

2019-04-20 18:20:12 UTC  

@jeremy Ok, and?

2019-04-20 18:20:41 UTC  

before we start debating if earths a sphere or not we should know the curvature forumla

2019-04-20 18:21:20 UTC  

8 inches per mile squared approximately works, for maybe less than 100 mile distances

2019-04-20 18:21:28 UTC  

well what works for a whole sphere

2019-04-20 18:21:33 UTC  

thats what we are on

2019-04-20 18:21:50 UTC  

needs to work for more than 100 miles lol

2019-04-20 18:22:05 UTC  

Yeah, but it is rounded, and that slight difference adds up over long distances

2019-04-20 18:22:17 UTC  

7.98 is a more precise figure

2019-04-20 18:23:06 UTC  

whats the formula that works for 24,000 miles

2019-04-20 18:23:11 UTC  

And if you wanted to get even more precise, there is the slight oblate shape of the earth

2019-04-20 18:23:22 UTC  

But approximations are fine
