QUESTION:  If the Earth is really flat, then why haven't cats aready pushed everything off the edge?

If the Earth is spherical [Spherical Earth Theory], why do we fly planes when we just have to go up and wait for it spin around beneath us? A helicopter would suffice in many cases.
And then you're likely gonna say: "But the atmosphere" spins around with the Earth", but does it? Look at a hurricane. Oh, and what makes a hurricane spin around at all? And air at different heights should spin around differently since, yeah, there's air coming along with your car while it's driving, too, but air is air; the upper levels aren't connected to the lower levels. It's about gasses.

Which brings us to more questions, like, if the Earth is spinning at 1000kph at the Equator, why does someone in, say, Finland feel the same amount of gravity as someone in Nigeria? Shouldn't the person in Nigeria be lighter because centrifugal force should be countering some of the weight that is caused by gravity?

By the way, Flat Earth Theory does supply logical answers to these legitimate questions, but i'd like to hear people squirm and exibit how spherical earthers will say just about anything to defend their world view first...  ;D

" The effective acceleration of gravity at the poles is 980.665 cm/sec/sec while at the equator it is 3.39 cm/sec/sec less due to the centrifugal force. If you weighed 100 pounds at the north pole on a spring scale, at the equator you would weigh 99.65 pounds, or 5.5 ounces less.

I don't know how or where you find this stuff, Jim, but thanks. The more data/facts the better.

If you are at either pole, you could board a hovercraft or helicopter and "wait for it (Earth) to spin around beneath", but the Earth isn't usually spinning in the direction we want.  At either North or South Pole, you would wait until the craft runs out of fuel, then land or crash land, right in the vicinity where you began.

Then if you wanted to fly from Chicago to New Orleans, you could wait as in the above example, but Earth is spinning in a direction somewhat perpendicular to your desired flight path, so you could get in your hovercraft above Chicago and wait, but because of the west-to-east direction of spin, you would hover over points along the latitude of 41.8781 degrees North, never reaching New Orleans....unless there's a pole shift and it shifts in such a way to ...well you know....

The only way I think this hovercraft business would work is if a person wanted to fly to a destination that is aligned with the ecliptic, and is at the same latitude as your starting point.  If the desired destination is westerly, just wait a while.  If desired destination is easterlty, wait a lot longer, and your drop off point will eventually appear under you. 

If the Earth is not spinning, then that must mean the Sun is moving around us, just like they thought in the Dark Ages.

The truth of the matter is that whether you fly east or west, your plane trip will take the same time and it just depends on the miles/kms one has to cover. If the Earth is truly spinning at speeds exceeding that of a jet airliner, there is no sense to this.
In other words, it looks like people got it right in the 'Dark Ages'.
In the words of Sir Arthur Conan Doyle: "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth".

Popular/modern schooling implies that 'primitive man' thought the world was flat but, supposedly, now we all know better. This view, however, is political and part of popular myth; even 2500 years ago there were folk who thought the world was round/spherical, just as flatearthers today doubt the mainstream view [much like how people considering the matter of Planet X fall way outside the mainstream...].

With governmental agencies like NASA monopolizing space, we may never know the truth of the matter. But as the above logic suggests, whatever the truth, neither view is so self-evident that the other is ludicrous, or even unproven.

Weather generally moves from west to east (excluding Coriolis effect in northern hemisphere) - or rather, the Earth rotates from east to west underneath it. 

" The greater the difference in air temperature, the faster the jet stream, which can reach speeds of up to 250 mph (402 kph) or greater, but average about 110 mph (177 kph). Both the Northern and Southern hemispheres have jet streams, although the jet streams in the north are more forceful.Mar 11, 2013
What is a Jet Stream? - Live Science
https://www.livescience.com/27825-jet-stream.html "

So, airplanes flying from west to east can sometimes catch a tailwind and arrive early.


From https://www.vcalc.com/wiki/MichaelBartmess/Rotational+Speed+at+Latitude
------------------------
*  If we enter the latitude 0 degrees to determine the rotational speed at the equator, we find the rotational speed of a point at the equator is approximately 1037.6 mph.
*  If we enter the latitude of London England (about 51.533 degrees), we find the rotational speed of the London Bridge is approximately 645.4 mph.
*  If we enter the latitude of Anchorage, Alaska (about 54.667 degrees), we find that city has a rotational speed of approximately 600 mph.
*  If we enter the latitude of Reykjavík, Iceland (64.0667 degrees), we find that capital has a rotational speed of approximately 453.8 mph.

The ancient Greeks figured it out - long before that ancient peoples knew about the basic structure of the solar system and they did carvings showing depictions of the solar system and round objects up in the sky... they sure as Hades were not talking about flat disks of planets moving through space.

And didn't the Sumerians also know of the same stuff....thinking of the clay scrolls that Z. Sitchin translated, and which contained all those "engravings" of the objects in space similar to what you have posted.

That's partly what I was referring to... in the Middle East...Sumerians...
and true that illustration is similar or one of the ones used by Sitchin

Tiamat
« Reply #11 on: February 22, 2018, 12:46:34 AM »
According to the Sumerians as translated by Sitchin, there was Tiamat which was struck by one of Nibiru's/Nemesis' moons and broke up. Most pieces are now what are known as the asteroid belt [Tiamat's orbit was between Jupiter and Mars] but one chunk of it remained and became Earth, entering a new orbit.

This is why Earth isn't flat but flattish, for it is one piece of a planet [Tiamat] which was much larger than (say) Mars / Venus, though no gas giant; perhaps closer to Saturn in size.
As flatearthers point out, the supposed measurements of Earth don't work out; if one takes the supposed size of Earth and what the circumference should be, we shouldn't be able to see very far because the horizon falls away quite quickly. However, it turns out that it's possible to see much farther than this mathematics would suggest. This makes sense if Earth is indeed rounded, just not spherical. So then there is a horizon, it's just much farther away than sphericalearthers suggest. Sun and moon, therefore, can also fall away over said horizon.
Think the Agents of S.H.I.E.L.D. destroyed Earth and imagine our moon as Earth next to what's left of Earth [in Agents of S.H.I.E.L.D.] as (what's left of) Tiamat:



Or imagine a planet the size of Uranus and how it's circumference compares to how Earth is popularly supposed to be; a (leftover) chunk of a planet of that size might have the mass we associate with Earth, but not be spherical at all, except (rounded) on one side.

It's been known for quite some time the earth is a "flattened spheroid" which IIRC is the term I picked up from a decades-old astronomy book.  Another term IIRC was "oblate spheroid", but that's not totally correct because I think oblate suggests flattened at both poles.  It may be, but one pole is more flattened than the other.  It's not almost pear-shaped, but leaning in that direction.

I didn't think you really believe the Earth was FLAT, sort of like a Frisbee.  If it were, then of all the thousands and thousands of lunar eclipses, some would have had to show something other than this spherical-like Earth shadow moving across the moon.  (We would have seen that Frisbee shape at least sometimes.)  Of course, it's not a true, absolute sphere, but it's more spherical than square, or Frisbee, or tetrahedron, etc., etc.  LOL

True, ilinda, oblate spheroid.
...
What is the exact shape and size of the Earth?
Using those measurements, the equatorial circumference of Earth is about 24,900 miles (40,070 km). However, from pole-to-pole — the meridional circumference — Earth is only 24,812 miles (39,931 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.Sep 15, 2017
