Are you admitting you guys have been wrong all this time?

And the spheres depicted in the composites are not spheres?
Wrong about what? It has been long since known that the earth is not a perfect sphere but slightly flattened.
Note the "slightly"
Here's a composite image of the earth from space:

Does that look like a perfect circle? Is it one?
Hint: load that image in a paint package and measure the number of pixels top to bottom and then left to right...

Tom: "Claiming incredulity is a pretty bad argument. Calling it "insane" or "ridiculous" is not a good argument at all."

TFES Wiki Occam's Razor page, by Tom: "What's the simplest explanation; that NASA has successfully designed and invented never before seen rocket technologies from scratch which can accelerate 100 tons of matter to an escape velocity of 7 miles per second"

Silly you, don't you know your screen resolution will affect the shape? What if you have a widescreen and it flattens the image(!)
Tom is wrong most of the time. Hardly big news, don't you think?

I think he thinks the earth's flat surface has been mapped onto a spheroid then that spheroid projected into a flat map again to show the flat earth (which is massively distorted). Correct me if I'm wrong Tom.

I see.  How does that explain what this projection idea is all about.  This all sounds like forcing something to fit just to make a particular theory work which is actually clearly wrong in the first place.

If it was an article telling us that the systems were using round earth distance the title of the article would be "The Earth is Round!," markjo.
Then why does the article state that the earth is best described as an ellipsoid?  The article is using "round" to mean "sphere".  An ellipsoid is not a sphere.
So, all the crapola cried by RE is wrong?

It depends on what you mean by wrong.  It's been known and taught for many years that the earth is not a perfect sphere but an oblate spheroid.  However, the oblateness so slight that it does not affect our everyday experiences.  Earth scientists and pedants are pretty much the only people concerned with the oblateness of the round earth.

Correct. The slight polar flattening is caused by the Earths rotation. This is evidenced by the fact that the gas giant planets, which rotate faster due to higher mass show the flattening effect more than the Earth does. Therefore the faster a planet rotates the flatter it will become.  With a rotation period of 24 hours, the Earth spins far too slowly to become flat.

Geological records in rocks show that the Earth rotated much more rapidly in its early history. That means the flattening effect for Earth would have been more pronounced in the past.  So as it slows down, it is getting less oblate spheroid and more spherical.
