I've been researching flat Earth for years, and I say "yes." There is an excellent chance that all of us have been lied to for our entire lives about the vary ground we walk on. I am not smart, but there is much physical evidence that would suggest that we have been lied to for centuries about the shape of the Earth, and reality in general.
You must do your own research and stop believing what you were taught at an age where you still believed in Santa Claus, The Easter Bunny, and the Tooth Fairy.

@TBIman In physics a law describes a natural phenomenon, but does not attempt to describe how it works. Newton's law of gravitation describes the attractive force F between two bodies with masses m 1 and m 2 , which are a distance r apart.
@TBIman Question : [b]does it work ?[/b] Atomic theory is just a theory, but we used it to light up houses and blow up cities. But it works. Germ theory is a theory, but it also works. We use it to make vaccines and save lives. Evolution is a theory. But you can’t have millions of different species without it. In short , it works. Gravity works too. That’s why we still take it into account. Flat Earth, not a theory, why ? Because [b]it does not work ![/b]
@DocSavage You're right. But Flat Earth is a working theory that describes reality better than anything else we have. I suggest that you look into it and apply it to the world that you live in.
@TBIman Why not provide us with a link. Everything you claim can and has been easily refuted. Even your spinning ball. Unlike creationist, you can’t get away with just saying “god did it” there are in fact things in reality that are impossible. Flat Earth is high on that list. You simply can not make work, and you lying if you say otherwise.
@Ryderbike The question has always been "HOW" do you know that the Earth is not flat? I would very much like to be sure of where I live. If you really want to prove the globe you will have to find measurable curvature which no one on Earth has ever done.
@TBIman We have been measuring the Earth for over 2,000 years!
It's called Geodesy[1], a branch of applied mathematics and science that deals with the measurement of the Earth and its gravitational field. Here's some history[2]:
The spherical shape of the Earth was most widely supported during the Greek Era and was postulated by Pythagoras and later by Aristotle. Plato took a guess at Earth's circumference but was way on the high side. Archimedes did an estimate and got closer but was still a good bit over.
Eratosthenes[3] (276 BC - 195 BC) was said to make an accurate measurement of Earth's circumference (half a percent too high) by measuring the difference in shadow angles of the Sun from two different cities along a north-south line 575 miles apart.
@TBIman he Indian mathematician Aryabhata (AD 476–550) was a pioneer of mathematical astronomy and estimated the circumference of Earth with an error of only 1%.
Early Muslim scholars were interested in calculating the distance and direction from any given point on Earth to Mecca, so Muslim mathematicians developed spherical trigonometry. Around 830 AD, a group of astronomers led by Al-Khwarizmi measured distances in modern Syria and used it to make a fairly accurate calculation of the Earth's circumference.
The medieval Persian Abu Rayhan al-Biruni [4](973-1048) made important contributions to geodesy and geography. His calculation of Earth's radius was only a quarter of 1% off the actual radius we know today. Instead of using sun shadows from various latitudes, he came up with a novel technique of measuring the "dip angle" of the horizon from the top of a mountain and made use of trigonometry:
@Ryderbike That may or may not be true, as you just read it somewhere. What I and many others are looking for is measurable curvature of this place we call Earth. How are we supposed to measure the Earth? I do not think that it's even possible to measure the whole Earth. So what so many flat Earthers have done, is take their super zoom cameras to the edge of calm water and looked across it. Depending on the visibility index for that day they are seeing waaaaaaay farther than would be possible on a 24,901-mile ball. Why is that?
@Ryderbike If you think that those are photographs you are beyond saving. Space doesn't exist and those are cartoons. Why don't you do a little research? NASA has gone on record saying that the last time they took a photo of the whole Earth was in 1972, and even that one was fake. They shot the Earth through a round window in their high-altitude plane.
