that is, where the sun sets, the place where the dome seems like touches the ground and the horizon meet in the same place.

If Dome exists it covers the whole Earth.

Looking from Africa you see Sun sets somewhere in Brazil?

Why people don't see end of the Dome there?

In reality your horizon is much closer.

Stand at a beach by the sea:

Sun during sunset is 6000 miles away, horizon is 3 miles away.

You cannot see 6,000 kmeters horizontally with the naked eye, an object at that distance merges on the horizon. This also has to do with the fact that angular size is

a reverse trigonometric function. The dome is not closed in the form of a semicircle. So the angular size quickly shrinks to you according to observe point at the horizon

at 6000 km with a difference you can't notice. **I hope you can understand that. I hope you can get this.**

There isn't a gap between dome and atmoflat.

The highness of the dome is 100 kms.

I tried to understand, but, as I said, horizon is not 6000 km away. You know it very well.

If we apply standard refraction then:

If you are 2 m above the sea, horizon is 5.45 km away.

If you are 1 km above the sea, horizon is 96 km away.

If you are 10 km above the sea, horizon is at 304 km.

If you are 100 km above the sea, horizon is at 966 km.

And you say that Dome is directly at 100 km.

**Do you see now what is the problem?**Please calculate the appearent size of an object has 100 km high and 6000 kms distance to the observe point first.

If you draw it considering centered observe point and dome's apperance depends on its angular size to observe point then this turns a realistic drawing can be talked about.

Object 6000 km away and 100 km high is (in direct line) is 6001 km away from the eye.

SQRT(6000

^{2} + 100

^{2}) = 6000.8

The triangle has very sharp angle and the difference between the hipotenuse and the leg is small.

ArcTan(100/6000) = 0.95 degrees.

Apparent size of an object at that distance depends on physical size of the object.

For example: object with diameter of 30 km will have apparent size (angular diameter) of

2 * ArcTan[(30/2) / 6000.8] = 0.286 degrees = 17.16 arc minutes.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Right now, at this very moment, I think that it is important to imagine two people looking at the Sun simultaneously from two places very far away from each other.

Where is the dome for some guy in Istanbul, and where will guy from Madrid see that same dome?

Guy in Madrid will have Sun still 32.8 degrees away from sunset.

Time difference is 2 hours and 10 minutes and the distance is 2740 km.

And in reality Sun travels at the constant speed of 15 degrees per hour.
