The Earth is very special for sure, per those really in the know. Using the "P" word for Earth requires proof.
You don't need an observatory or, for that matter, a rocket to know the Earth is flat.
It seems whenever REers try to prove a claim they either enter an observatory or climb into a rocket and fly away.
Observations on Earth are the best way to substantiate claims of Earth shape.
Why are flat earthers so adamant in their belief of this flat earth nonsense when there are absolutetly no facts or evidence to support it ?
The earth has been always a globe and there have always been facts and evidence to support it for over 2500 years ?
Is it just some sort of insanity ?
Admittedly if you are not in some field of work where knowledge of the globe is essential, you wouldn't need to know what the shape of the earth is.
Not knowing this , simply "it looks flat where I'm standing" might be the only reason ?
I just started this thread or subject because I'm just curious as to why some people still think the earth is flat in the year 2018 ?
To Gotham:
What would you say about an observation of the horizon would be in relation as to whether or not the earth is flat or has a curvature ?
You don't need to go to an observatory or a rocket to observe this. You would , however , just need to go down to a beach or shore to observe this best.
Here is just one practical (and actual) application of "Observations on Earth" :
The elevation of Point Loma at San Diego, CA, USA is 422 feet above sea level.
The elevation of Diamond Head at Honolulu, HI, USA is 762 feet above sea level.
There is nothing but the Pacific Ocean between them.
The distance between them is 2601.89 miles.
If the earth was flat , and If I had a powerful enough telescope with the proper filters to see through "the thickness of the atmoplane" I should surely be able to see Diamond Head from Point Loma.
But I can't.
Why not ?
Because of the curvature of the earth I can only see as far as to the horizon....Because the earth is a globe.
If I am on the top of the peak of Point Loma I can only see about 25 or 30 miles at the most to the horizon.
And likewise a person at the top of the peak of Diamond Head should be able to see Point Loma.
But they can't...For the same reason.
Been. there..?Done that....At Point Loma.
