Gyrocompasses make use of very real Earth’s Rotation

Not only do gyroscopes drift because of earth’s rotation if not corrected for as in an artificial horizon.

One of the prevalent examples from “Behind the Curve”  where earth’s rotation causes a gyroscope to drift.

One of the more jaw-dropping segments of the documentary comes when Bob Knodel, one of the hosts on a popular Flat Earth YouTube channel, walks viewers through an experiment involving a laser gyroscope. As the Earth rotates, the gyroscope appears to lean off-axis, staying in its original position as the Earth's curvature changes in relation. "What we found is, is when we turned on that gyroscope we found that we were picking up a drift. A 15 degree per hour drift," Knodel says, acknowledging that the gyroscope's behavior confirmed to exactly what you'd expect from a gyroscope on a rotating globe.

Anyway.  You can limit a gyroscopes motion by limiting how its gimbal move to use earth’s rotation to create torque so the gyroscopes will point north.

Debunking Flat Earth: Gyrocompass Aligns with Earth's Rotation

 Not only does earth’s rotation causes gyroscopes to drift, whete there only systems to correct / compensate for this drift, but earth’s rotation can be used to create torque to get a “caged” gyroscope to point north. 

That is quite cool. I've heard they are used on boats since the metal and similar can interfere with regular compasses. They use a bit of power to spin, and detect changes in angle or similar to find north. This pic showed one that uses a USB cable.

‘…gyroscopes drift because of earth’s rotation’ — Jumping to conclusions isn’t very scientific.

Then how did a flat earther use a ring laser gyroscope to detect a drift that happens to match the round earth's alleged rotation?

Good thing people aren't just jumping to a conclusion.
Instead, they are reaching a conclusion supported by mountains of evidence.
That includes the fact that this drift is entirely consistent with what is expected for a rotating round Earth.
The only other option is some magic field causing the same results.

It would be the FEers jumping to conclusions, that something else must be causing it, because they can't accept Earth is round and rotating.

I’m sure there will be a simple science based explanation for what’s going on. I shall endeavor to find out and let you know so that you don’t have to reach for fantastical ideas about round earths etc. You guys!

Mountains of evidence - good one! On the FE side we just have evidence of mountains - land points we shouldn’t be able to see because of curvature.

Yes, that Earth is round.
Something no one has been able to show issue with, including you.

Mountains of evidence - good one! On the FE side we just have evidence of mountains - land points we shouldn’t be able to see because of curvature.

You mean you have baseless claims of mountains you shouldn't be able to see because of curvature.
Meanwhile, there are plenty of examples of mountains where the bottom is missing, because of curvature.

Now care to tell us how gyrocompasses work?

 On the FE side

Where the topic of this thread is Gyrocompasses and why they point north.  Evidently FE doesn’t have an explanation. 

The topic of this thread isn’t FE gaslighting addressed in numerous other threads. 

Doesn’t gravity hold everything to the ball earth rotation?

But you’re now claiming there IS ONE INSTRUMENT, which the made up force, cannot hold  to Earths curvature and/or to Earths rotation, what a joke

Why can’t you keep your stories straight and consistent, everything you say about it never holds up, has every excuse for all the failures of it.

Why no made up force here? What’s next?

Planes aren’t held to Earths rotation? If they are, so would the instruments inside the planes, held by gravity accounting for Earths rotation with planes!!

Doesn’t gravity hold everything to the ball earth rotation?

No, it attracts things to the surface.
Friction with the surface would keep it moving with the rotation.

Planes aren’t held to Earths rotation?

No, they fly based upon the air.

Why can’t you keep your stories straight and consistent

We can and do.
But because that so trivially destroys your pathetic BS, you need to repeatedly lie about it, just like you have down now.

You can't explain how a gyrocompass could ever work in your delusional fantasy, so you just lie by pretending gravity is meant to magically lock everything to Earth's rotation, even though no one other than lying FE scum like yourself have ever said that.



Now care to stop with the pathetic BS and explain how gyrocompasses would work in your delusional fantasy?

Is the plane held by the made up force to the rotation of Earth, or not?

Yes or no?

Now you say the made up force doesn’t hold everything in exact position while Earth rotates?

So if a hundred people went up in a hundred balloons at the same time all over California, say, at a fixed position, some would see earth rotate a bit?

I’ve never heard your side claim anything wasn’t held to the rotation of Earth by your magic force until now!

Anything else to add? I can’t wait to hear about it

If Earth rotated, every point on Earth would have a different rotational angle.

From a point along its direction of rotation, we’d see the stars move up towards us and back down behind us, rotating as a thick line opposite to us.

Seeing stars circle around us anywhere on Earth is only possible if Earth is a flat surface, and stars move around us in a circular path.

Each area on Earth sees a circle, a smaller circle of the entire circle of stars.

Each area has thousands and thousands of stars over it, all circling over that one area, and some are part of another area, with other stars, and so on.

Doesn’t gravity hold everything to the ball earth rotation?

But you’re now claiming there IS ONE INSTRUMENT, which the made up force, cannot hold  to Earths curvature and/or to Earths rotation, what a joke

Which in no way is an attempt to discus why a gyrocompass is a reliable instrument and why it points to north accurately.

Turbs, you have to just be a troll at this point.

Or can in an act of good faith in anyway describe in a logical and scientific manner how a gyrocompass works, how it reliably points to north, and the evidence of that for RE vid FE?

Is the plane held by the made up force

There is no made up force. Grow up.

Now you say the made up force doesn’t hold everything in exact position while Earth rotates?

I have never said that.
That is a strawman you are creating.
It shows how utterly pathetic and dishonest you are.

I’ve never heard your side claim anything wasn’t held

And more pathetic, dishonest BS.
Notice how you try to shift it?

How often have we heard your side say it is bad idea to jump foot first into a woodchipper?
By your complete absence of honesty, I guess that means I can your side always claims it and is clearly insane?

What kind of honest person would ever accept that? No one.
Again, you can't just appeal to people not claiming the opposite of your pathetic, BS, strawman.

You need to show where any REer has claimed gravity is magic glue which magically holds people to Earth and magically locks their rotation.
Do you have any evidence of anyone claiming such utter garbage? Or is it just a pathetic strawman you have brought up to deflect from yet more proof that your pathetic, delusional fantasy does't work at all?

All this pathetic BS with the pathetic strawman, all to avoid admitting you have no explanation at all for how gyrocompasses work.

If Earth rotated, every point on Earth would have a different rotational angle.

Or the honest way to word it is that the axis of rotation is at a different angle relative to the surface of Earth.
And it is.
As we see with things like the angle of elevation to the celestial poles.

From a point along its direction of rotation, we’d see the stars move up towards us and back down behind us, rotating as a thick line opposite to us.

Do you mean how at the equator we see stars rise due east, go directly overhead and set due west?
Something impossible in your flat Earth fantasy?

So you want to deflect from your complete inability to explain gyrocompasses to instead appeal to how the stars clearly show Earth is round?

Yet again, all you have is an absolutely pathetic deflection from your complete inability to explain how gyrocompasses work.

Repeatedly saying what is shown and not shown is not a valid argument!

Stars have never changed, never moved at all, never changed position relative to other stars. All things on Earth and above Earth have never moved position at all ever.


YOU say they have changed position, that all things on Earth were elsewhere sometime before.

Your the one who must show evidence for your claims!

Do you mean how at the equator we see stars rise due east, go directly overhead and set due west?

Really? Show me the proof of that!  I’ve never seen it

Are you now saying we can go up in a balloon and stay in one position and see the Earth spin at 1000 mph below us?

While it never moves at all?

You claim anything and everything and conflict arguments all the time. The moon is held away from earths gravity in a rotation, pulling it from millions of miles away and stops pulling it suddenly , closer to its source, and somehow makes it spin around the ball earth after it stopped pulling it in!  When closer to its force!  Sure!

The force of all conflicts and magical powers, that lets insects beat it but not oceans or buildings!  Pulls in a huge object from space but can’t pull it in nearer its force, holds astronauts down to Earth and then lets them float in space, but keeps the moon around here!

We can say the Earth is a square block and it’d be better than your ball Earth!


Are you saying that if we looked at a horizon across it, from before it and after it, over three plus miles, we would sse the surface curve down?

The ship wouldn’t be seen past three miles from tbat viewpoint?


Nice bs story

Repeatedly saying what is shown and not shown is not a valid argument!

Do you know what certaily isn't a valid argument?
You continually asserting pathetic BS with no evidence at all, all while desperately fleeing from the topic at hand.

Your the one who must show evidence for your claims!

No, not how it works at all.
YOU claimed they are all the same, and are fixed and have magically never moved, so YOU would have to show proof.
But again, this is just another pathetic deflection by you.

Show me the proof of that!  I’ve never seen it

No.
It has nothing to do with the topic, and I was just pointing out how even your pathetic deflection doesn't help you, and how you are wilfully lying to everyone.

If you want to see it, go to the equator.

Especially considering you just reject everything that shows you are wrong as fake.
You are truly pathetic.

Are you now saying we can go up in a balloon and stay in one position and see the Earth spin at 1000 mph below us?

No, that is just a pathetic strawman by you.
Can you do that inside a car? Just have the balloon go up from the floor of the car and magically the balloon is fixed and watching the car fly past? No.

You claim anything and everything and conflict arguments all the time.

No, I don't.
YOU DO!
Because you can't defend your complete and utter bullshit, you just wilfully lie about the RE model, inventing all sorts of BS about it, to pretend it doesn't work.

The moon

is in orbit around Earth, with the mutual gravitational attraction causing the moon to accelerate towards Earth in its orbit.
Gravity, along with its tangential velocity keeps it in an orbit.
Gravity is not magically fixing it in place.

The force of all conflicts and magical powers

Is your pathetic strawman that has nothing to do with gravity.

Are you saying that if we looked at

No. I'm saying gyrocompasses rely upon the rotation of Earth to work, and are further proof of the fact that Earth is rotating and round.
But because you are pathetic, lying subhuman piece of shit, you need to continually deflect from this and spout all sorts of dishonest, delusional BS.

Now again, stop with all the BS.

Can you explain how gyrocompasses work in your pathetic delusional fantasy?

Gyrocompasses still point north because of earth’s rotation.  FE can’t prove otherwise because that’s how they work. 

is in orbit around Earth,

Who derails threads.


😂😂😂😂😂😂

Poor Turbs.  Doesn’t know what to do with proof the earth rotates.  Can’t explain in any working way how a gyrocompass would work for FE.   Especially when it’s designed and works as designed for a RE.

You really believe this instrument was designed to work for a ball Earth?

Because it’s shaped as a ball?

It’s shaped as a ball, to measure any deviation in any direction at all.

What detects your supposed rotation of a ball Earth?

Gyroscopes don’t and couldn’t measure any sort of rotational motion of a ball Earth, don’t try to make this crap up, its completely ridiculous

You really believe this instrument was designed to work for a ball Earth?

Yes. Like any sane person would.

That is because the principles of operation rely upon this round Earth rotating, causing gyroscopic precession which results in the gyrocompass pointing north.

If Earth wasn't rotating, it wouldn't work.

Just how could it work in your delusional fantasy?

Because it’s shaped as a ball?

No.

No one thinks that. No one claims that.
But because you can't deal with the topic at hand you need to spout complete and utter garbage.
It shows how utterly pathetic, dishonest and desperate you are.

You can't refute what is actually said, so you just blatantly lie to everyone.

Gyroscopes don’t and couldn’t measure any sort of rotational motion of a ball Earth, don’t try to make this crap up, its completely ridiculous

You sure do love contradicting yourself.
Didn't you previously claim that gyroscopes allegedly prove Earth is not rotating because they don't measure the rotation?
Only to now directly contradict that by claiming they couldn't measure it?

But this isn't about a gyroscope directly measuring the rotation as countless examples have already provided.
This is about a gyrocompass, a tool for determining the direction to north.

Now again, can you explain how a gyrocompass works in your pathetic, delusional fantasy?
If not, can you show a single shred of integrity for once in your pathetic, dishonest existence and admit you have no explanation?

They don’t read for North, or your North Pole of a ball Earth.

They read for the true center point of our flat Earth, and that is the ONLY point they read for on Earth. A gyrocompass would read for north the same way but atop a spherically shaped instrument. 

Hey, I just thought of something….shouldn’t the gyrocompass read for South as well as North? They’re both magnetic points on a ball, on opposite ends of the ball.

It’s really sad that you think a ball instrument is measuring for a ball Earth, when it should read BOTH North and South piles of the ball, it would really support your ball Earth argument for the first time! All the other instruments support and measure for the flat Earth, that’s why you had to plug your made up pulling force into the mess and solve it for you, or at least try to solve it. But even your magical force cannot solve for it, even adding in your made up core inside the ball Earth, and anything else you’d like to shove into this crap….

This fairy tale should have been flushed down into the sewer years ago, but we’re getting closer and closer to shredding it all the time.

There’s only going to be people like you, who do nothing but claim bs and lie about anything, because your life is nothing but hate and fears and intense insecurities. So good luck with that.

They don’t read for North, or your North Pole of a ball Earth.

Gyrocompasses are designed and made to use torque produced by earth’s rotation to point north.

What force would FE produce to keep the gyrocompass pointing north.
