I have read that authors book more than once and have done plenty of personal research/investigation into it pertaining to many of the authors claims and found them to be more than valid but true. I seriously doubt he could be wrong about everything. He is human thoughhappy.png

I did not think a question could be considered blundering. Especially a question that could have multifaceted answers! 

Or are you referring to Einstein's quote? 

Or something else entirely? 

I am referring to this crucial quote from your blundering source.

"Since under the heliocentric model the earth is supposed to be spinning in an easterly direction, a viewer who is looking at the North Star would necessarily see all of the other stars travelling in a westerly direction across the sky."

This is blatantly false and reveals the source to have fatally poor understanding. The Earth rotates anticlockwise (that's what rotating East means) so the sky appears to rotate clockwise around the pole.

Surely you can see his blunder now? Westward actually means clockwise around the North Pole, not a linear direction. This is true both on the ground (as you should agree) and in the sky.

Which way is Westward on this map?

I would say North America would be west of the north pole if north is up and south is down. 

I was thinking about your merry-go-round example. 

Were you implying if the time lapse camera was placed on the merry-go-round while spinning it would have proved the earth was moving and not the stars?

No. North is always the direction of the North Pole (so whereever you are on that map it is a radial direction towards the centre).

And West is always to the left as you face North (i.e. clockwise round a line of latitude). 

I was thinking about your merry-go-round example. 

Were you implying if the time lapse camera was placed on the merry-go-round while spinning it would have proved the earth was moving and not the stars? 

I like your thinking, putting a long exposure camera on the merry-go-round. That is a good scientific step, recording objective data. And this is a perfectly practical experiment, requiring only a camera and a tripod or other way to fix its direction over a long exposure.

The result is that, whatever direction it is pointing in, there will be circular streaks centred on the point on the axis of rotation - i.e. the point directly above the merry-go-round.

So if the camera is pointing straight up, the circles will be centred in the middle of the photo, but if it is pointing in some other direction, they will be centred somewhere off centre. This is just like what you see when you are not at the North Pole - the sky seems to rotate about an off centre point, because the ground is not pointing at the North Star.  On a hemisphere, only the point at the North Pole is pointing at the North Star.

You can see what your source couldn't. He got it wrong. This meant that the ENTIRETY of the reasoning in your lengthy quoted text was simply wrong.  I am sure I could find a similar clear error in every single argument he reaches which concludes something that is false.

Okay Elroch, you were using a map that only shows the top of the globe so yes, I see what you mean. However, that would not work on the Gleason map or the UN map(which is identical) that shows the entire known world. 

NameofNames - The thread is about cosmology. Not the wonders of the world. But I understand where your coming from. The first time I encountered flat earth I told them to go take a flying leap off the edge!

I dont really know much about earth, well, im not dumb, i know stuff, but im not fasinated in that kind of stuff

it not really my thing yk?

NameofNames - Wrong according to whom? 

Even NASA official aeronautical documents state the earth is nonrotating stationary & flat. 

Why is that if it was pure fantasy?

Now im REALLY confused. Anyone want to educate me a little? Please?

Now i will say, Earth is round. So I believe!

Dang bro, How old are you? Are you even in schoool anymore?

Avatar of noodles2112

NameofNames - when did I say I believed the earth was a sphere? 

Be that as it may, round does not necessarily imply spherical. A frisbee is round and dish/disk can be round, coins are round, but none are spheres.

Ok is this a computer chat thing? Im SO confused!

HottieRhayaM - were are discussing the differences between geocentricity and heliocentricity.

oh ok! I have no idea what those words mean! But thank you

NameofNames - I was just letting you know the first time someone told me about flat earth I REACTED emotionally. As most do when hearing about it for the first time. 

The only planets I see that are spherical and terra firma are presented via NASA. 

Amateur astronomers post pics and video footage of luminaries. Some round and some appear spherical but that has nothing to do with the shape of the earth. By that logic one could assume a pool table is spherical because the pool balls are spherical. 

Big difference!

The moon could be spherical. It certainly has the appearance of being so. But is it a rotating sunlight reflecting rock ball? Observably not. Does it cause the tides? Demonstrably not.

That makes no sense.

Since we were discussing observations of the North Star, only the Northern hemisphere (projected onto my map) is relevant. You CAN'T SEE the North Star from the Southern hemisphere. Rather you see the South Pole of the sky and the star rotating around this. That is because it is the bottom hemisphere of the ball-shaped Earth (the North Star is above the middle of the upper hemisphere).

Very simple, and known for over 2000 years.

Good decision.

NameofNames - the main premise of heliocentrism is a ball earth with an uncontained atmosphere(air pressure) coexisting aside an uncontained vacuum. Ever see what happens when a contained vacuum is subjected to air pressure? It implodes. 

That is why the ancient astronomers referred to planets as 'wandering stars' each having their own distinct patterns. But they never referred to them as terra firma.
