I am pretty sure I can see farther than you say I possibly can.
Yet you can never provide a concrete example of that. Instead it is just the same repeated claim of being able to see further than you think you should be able to if Earth is round.
Have you factored refraction into this?
But i'm warning you - if your wrong you're doing a major diservice - don't you fear the reprecussions? So what is the easisiest way I can confirm for myself that the earth is actually a globe?
This depends on how far you can travel, if you have people you trust in other locations around the globe, and what equipment you have.
Pesonally, I like the 2 celestial poles, always 180 degrees apart which can be circled. But while you can measure that fairly easily in your location (at least assuming you aren't too far north or south), it is harder to measure it around the globe by yourself.
So an easier way is to measure the angle of dip to the horizon. You can get a theolodite app for your phone, which you can then use measure just how far below level the horizon is.
If you do this, you will find it is basically level at no altitude, and as you get higher, it gets further below level. If you can accurately measure the angle, you can even calculate the radius of Earth.
But perhaps the simplest observation of all is viewing a distant ship/building/structure which is beyond the horizon, and observing that the bottom is obscured, even if you use a spotting scope, and if you go higher, you can see more of it.
You guys have seen the long range photos?
Do you mean the very long range ones, where instead of a nice clear horizon as you would expect from a low altitude on a FE, you instead have much more of a haze, with the ground blurring into the sky? If Earth was flat, that is what you would expect all the time.
But more importantly, do you mean the ones showing known mountains, where the more distant mountains, which are higher than some of the nearer mountains, appear lower in the photo, even though the photo was taken from an intermediate altitude?
Or do you mean like those clealry showing the bottom of buildings or the bottom of an entire city apparently submerged below water?
These long range photos are entirely consistent with a RE, and refute the FE.
Edit: My bad, it seems I didn't finish this. Finished now.
