Flat Earth Believers, I would like to hear your ideas.

Gravity explained.

Gravity explained

Yeah, no.

Still, gravity remains one of the greatest mysteries of the universe. Even though scientists can explain how it behaves, they are still trying to pinpoint what causes gravity and how it really works.

I was referencing the article.


That supports the basics of gravity and trying to understand it.


No, we do not fully understand it.


Spheroid earth, however, we do know.

Great video - has this been challenged? According to the calculations we should not be able to see an island 31 miles away due to the curvature of the earth

a reply to: TheConstruKctionofLight

No we should not see an island with an elevation below 470 ft. in this case, at all.

Middle Anacapa has an elevation of 325 ft and we see a large part of it.

Actually no, i made the same observations my self, FlatBastard says he has seen the same.

There are calculators for curvature which do account for refraction but the percentages are too small, and very wildly on many factors, which should present a problem when trying to make a constant observation, but the consistency remains.

If the curvature calculations are wrong, then all spheroid models that depend on that calculation are wrong.

I was thinking whilst driving tonight about some other things that prove the spherical earth rather than the usual ones and I got thinking about gyro compasses and fibre optic compasses. Both essentially detect the direction of East as it is the only constant movement (earth's rotation) if the compass is stationary. Any other movement (across the surface of the earth) causes a measurable deviation that can be turned into a direction.

In and of itself that wouldn't be inconsistent with flat earth but gyro compasses suffer from a well known problem called (latitude, course and speed error) which is a calculable error in that is based upon direction of travel, speed and latitude.

SinAz = Velocity x CosCourse / 900CosLat

The important part is the 900 cos lat as that is the calculation of the speed of the easterly motion of the earth. At the equation you have to rotate the full circumference of the sphere through space so move at 900 knots. At the pole you are only rotating not moving so your speed is 0 (cos 90 = zero).

If the earth was flat then you would move faster in the southern hemisphere than in the north. The plot for cosine isn't consistent with this.

That's a tough one for me, a good point indeed.

But correct me if i am wrong, do all those not seek north as their true reference? Some debate even that the fibre compass and such as those detect earths rotation.

But from my limited knowledge do they not create their own angular velocity, not the fibre compass, those use lasers, and both actually use an input from a computer.

So as long as your reference is the true geographic north are not all other directions just east, west and the opposite of north, South, would not the same effect apply.

Now i don't about the whole thing about being able to measure rotation of Earth, that's an interesting one.

Aren't gyrocompasses set to point true North, using other methods, and keep pointing in that direction regardless of a ship's movements because of the gyroscopic effect? I don't think they are being used on ships or planes to calculate North based on how it supposedly is affected by the Earth's rotation.

What is your experience with this if I may ask?

I am still reading on them, doesn't seem as though rotation of earth even matters, just a compass that points to the true north.

Interesting Buddhist flat earth map.

a reply to: FlatBastard

My experience is practical as a navigation officer in the Merchant Navy and theoretically as a lecturer in Nautical Science at a maritime academy.

If you look into the theory of how you turn a free gyroscope into a gravity controlled gyro and subsequently a gyro compass you will find that they rely upon methods of compensation for the earth's motion through space and would only be inherently accurate if the earth were to stop it's motion. Any movement causes a deflection in the calculated direction and the magnitude of this error is directly correlated to latitude. The magnitude of the error is identical at equal latitudes in both hemispheres. If all else (course and speed) is equal a vessel at 50ºN will experience the same amount of error as a vessel at 50ºS. If we are confident that the error is due to the rotation of the earth then a spherical model is the only one that would allow for equal rotational speeds at these (and all other equally numbered) latitudes.

Fibre optic compasses truly do 'sense east' as the ability to discern any direction is calculated through a process known as Kallman filtering which resolves rotational data from 3 separate axes into a direction of travel through space. The earth's rotation is a constant force that is irremovable. Once you know in which direction the fibre optic rings are moving then you know where east is. The prime reference point (North and this is simply by tradition and convention) is always 90 degrees anti clockwise from here.

Ooh, I have many questions. Allow me to do some more research first.

Flat Earth is truly a religion for morons.

Might want to research into Polaris too. You know? The thing flat earth morons can't explain, but ignore.

a reply to: TerryDon79

It certainly is not being ignored. It's not time for that yet, Terry.

It has been ignored by you and your cohorts. Mainly because you can't counter it or, most likely, can't find anything on you FE sites to counter it.

a reply to: TerryDon79

Like I said, the "ignoring" is coming from both sides, only I admit that I don't have all the answers, and I am not supporting the accepted, "logical" model.

And frankly, I don't care about what you have to say. You are of no influence.

a reply to: FlatBastard

You're ignoring science and literally having to make stuff up (not you, obviously, but the FE sites you get your "answers" from).

But never mind, you don't exist. I've never seen you, so my observation is you're not real.
