Flat earth test
« on: January 06, 2021, 02:03:25 AM »
😂 I believe I posted in the wrong thread I am sorry.

So as soon as I provide a legitimate method of testing for earth's curvature it's just deleted?!

Ok so here's an experiment that you guys can think about,  which should tell you whether the earth is flat, although I will be honest if legitimate scientific proof isn't enough I don't see what is.

Start at the north or south Pole or any point on the earth. Repeat this set of steps 3 times:
-Travel a constant distance (let's say 100km)
-Make a 90 degree turn in a constant direction.

Meaning that the distance travelled after each turn is the same and each 90 degree turn is in the same direction.

Here's the nice part that I think someone should try. If the earth is flat you won't end up where you started you will just have basically traced 3 sides of a square. However if as science proposes the earth is spherical, you should roughly end up back where you started. Given the Earth is not completely spherical there is probably a margin of error you can calculate as well.

This is just a very simple geometric observation applied to demonstrate the earth's shape and from what I've seen you guys love demonstrable science and experiments. So the only question remaining is does anyone want to try it?

Thanks for taking the time to read the thread, I'd appreciate your thoughts on the experiment / any queries.

The problem you run into is that your suggested method of testing doesn't yield the result you think it does. It would have been more fun to address this in the thread you already started, but you decided to start a new one so here we are.

How close to the starting point do you think you'll end up on a globe, and how close to the starting point do you think you'll end up on a FE? Let's start there. Keep your 100km-per-leg-of-journey assumption.

For added fun, after you think about this assuming you start at a pole, think about how it might work out if you start at the Equator, or in Boulder CO, or Sydney Australia. What if you shrink the distance to 10km, or 1km, or 100m? Is it different in any of those locations/situations? Why or why not?
