If the Earth is flat - how it’s possible:
You can make the following flights, starting at 9am, finishing at 3pm (or earlier) and staying at the hotel till the next day:
-
London, Uk => New York => Los Angeles => Tokyo => Doha => London, UK
-
The above series of trips starts and ends in the same place.
-
All the time, while flying, you’ve got the Sun on the left hand side.
You can only explain that in 2 ways:
-
Earth is a globe as we know it, or
-
Earth is flat, but then it needs to have a shape of a donut where the sun is in the center of it, so you fly around it.
The second would mean: when you fly South of London you should cross the middle of a donut (which is the Sun) after 12 hours of trip.
Let’s fly towards the sun:
London, UK => South Africa => the Sun.
Unfortunately, after 12 hours you end up in an extremely cold area.
So we are taught. But there are many unvalidated assumptions baked into such calculations. Astronomy is rife with them.
No, i have concluded it is wrong; slightly different.
The physics of light doesn’t prove nor measure a distance to a star.
Like what? If you are looking for empirical evidence, just ask!
Agreed.
Personally, i don’t think you should argue at all. It’s for fools. But if you had to - people who think rationally and can provide evidence for their claims would be more interesting than others, surely.
That is very sad. Arguing with idiots makes you even stupider (and belligerent) than they are :( I urge you to reconsider. Capable students prefer earnest discussion and research, and the intelligent have no need to argue with fools to feel better about themselves.
You can validate those assumptions with a pencil, paper, ruler, compass, and protractor. Or you can look up the proofs, as I'm sure they're on the Internet somewhere. Just search for "euclidean geometry". Once you understand triangles, you and a friend can simultaneously measure the angle to the sun from two places that are far enough apart. Then you can complete the triangle to find the distance. If the Sun is small and local, you shouldn't need to be all that far apart to have a detectable angular difference.
The same technique can be used to measure the distance to anything, whether it's a mountain in the distance, or a tree in your neighbor's back yard.
No, you can’t. The assumption of the earths orbit (and its correct diameter) around the sun yearly is baked into such calculations - for one.
Proofs do not exist outside of mathematics in an objective way. Proof is subjective.
I’m telling you that i have seen the “proofs” and they rely on unvalidated assumption.
I think this is a reasonable assumption. Many have completed this procedure and calculated the sun to be a few thousand miles away. Of course, for such calculations to be correct also requires the unvalidated (and easily refuted) assumption that the matter between the sun and observers does not alter its apparent path/position in any way. Because of air, for one, the sun often appears to be somewhere different than it actually is. Optics are tricky..
True, but the further you are from such observed points, the less accurate and dependable the procedure - for the same reasons above, and others.
There's just one problem with the procedure that just occurred to me now: If the Earth is round then the curvature of the planet would add to the observed angular difference.
