Flat Earth: Why doesn't a Plane's altitude meter (gyroscope) pitch up and down if it's a round earth

[Warden_of_the_Storm]

That's quite a stretch, no pun intended. However, There are people who have claimed to have found the grave of Noah and it was 18 feed long.

Anyway, this thread is way off the OP so I won't be continuing with this topic on this thread. Most posters are done here, I believe.

Agreed. We should probably let this thread try and get back on topic.

Because the earth isn't flat it's round and i can link you to live feed of the ISS as it does go around the earth
and if the earth was flat like you suppose it would see the edges. But if the earth was flat again gravity it would cause it
the "flat earth" into a sphere. Gravity it may be a weak force but it works and it keeps on earth getting rid of the flat earth hypothesis. Why gravity works well gravity in reality is just 2 bodies of mass interacting with one another also we are revolving around the sun so we aren't the center of the solar system. However though anyone and everything is literally the center of the universe since there is no defining center of the universe.

That's just how the Mercator projection looks. It's the same reason Greenland looks to cover such a large portion of the United States.

Check out this map, it's even worse:

In reality, Greenland is far smaller than Australia:

Here's a better map showing the extents of Antarctica:

I can't lie, I have seen that before, in a class.

I can just imagine the mainstream reaction to making the U.S. "smaller" and flipping the globe on its head...

Should we not use a map that makes everything correctly proportional, regardless of what people like or dislike or accept or reject?

1) Why doesn't a Plane's altitude meter (gyroscope) pitch up and down constantly if it's a round earth? NASA says the curvature is 8 inches per mile. The average speed of a plane is 580mph......how come the altitude meter stays mostly constant?

There are many different gyroscopes on an airplane, the altitude meter is not one of them.

Old school altitude indicators are air pressure calibrated -- during take off and landing you have to get the current air pressure at the airport and rotate a little knob to 'calibrate' the instrument for that pressure - this gives you 'accurate enough' altitude as you would be landing visually. Modern aircraft use many other techniques (including radar at lower altitudes).

An 'earth-tied gyroscope' (such as used in an attitude indicator) is vertically referenced and the spin axis is 'tied' to earth's gravity by means of a weight holding the spin axis pointing towards the center of the Earth. This is NOT perfect and must be calibrated frequently, especially if you subject it to strong forces.

So this objection ends up supporting the oblate spheroid model.

2) How come there are dead spots for GPS...but if you move a mile left or right, you get GPS connection. You mean a satellite cannot account for 1 mile difference?!?!? Before GPS, there was LORAN (https://en.wikipedia.org/wiki/LORAN)

It's called multipath combined with a low transmission power = lots of noise. Also depends on which signal bands your device is able to receive. Also heavily depends on what is going on in the ionosphere as that affects the propagation delay in unexpected ways.

LORAN only provided accuracy of about 300m @ 320km -- By using differential GPS and other techniques you can hit 10 centimeters world-wide. But yes, it works best outdoors where there are no obstructions of the sky. On the ground, especially in a city, you will have mixed results. Cell phones have TERRIBLE GPS hardware, absolutely lowest grade. That's why they augment it with cell tower and wifi triangulation.

Please cite exactly what device and firmware you are running if you want a better analysis - or you could just google it.

3) How come there are several space ballon videos showing a direct hotspot under the sun?

Do you mean specular reflections off the (slightly) curved surface of the Earth?

Why would you expect otherwise?

But please be more specific. Very hard to accurately address vague suggestions.

How come the sun appears very very close and not millions of miles away?

Lots of things APPEAR other than they actually are. When I hold my fingers up I appear to be able to fit someones head in between them. But again, please be more specific.

I will address one case which is when the sun's *near parallel* rays are streaming through the clouds and they APPEAR (due to perspective) to point to a sun that is practically in the clouds. This is a Very Well Understood Phenomena called Crepuscular rays.

They are NOT perfectly parallel, nor should they be, and the sun is large enough that there are umbral and penumbral effects.

Even wikipedia has this one right "Despite seeming to converge at a point, the rays are in fact near-parallel shafts of sunlight, and their apparent convergence is a perspective effect (similar, for example, to the way that parallel railway lines seem to converge at a point in the distance)."

When viewed from the right perspective this become obvious:

More: http://physics.stackexchange.com/qu...-the-sun-is-much-more-than-a-few-kilometers-a

Again, VERY well understood, so I'm SURE you aren't using this as an argument and you'll need to clarify.

Because ignorance in this day and age is still strong sadly...
Education really needs to be updated to so we never have this conversation ever again.... or any ridiculous claims for that matter. Sadly people still claim flat earth in 2016 again though flat earth is still a fairly new concept... it's as plausible as homeopathic medications curing cancer.

Are you saying that people should not question observations they make and continually hold the educators and scientists that we rely on for truth to back up their "facts". We should blindly follow the information that has been given to us by the only people that could, in the past, make these observations, when technology has advanced far enough for that the general public can make these observations for themselves and they are getting conflicting data?

If this is the case, we would be in a very different world than we are today. We should always allow the status quo to be tested and retested. Nothing should be taken as fact when it conflicts with what you actually observe.

I think you need to understand. Ignorance in this day and age may be strong for some. These are the ones that don't see that information and the ability to gain this information is growing exponentially. Observations and data that were once available to a privileged few, is now within the grasp of many. Ignorance is not strong and this is the big problem for the mass propaganda that has been fed to us. Ignorance is shrinking, knowledge is exploding. The great propaganda machine is trembling and scrambling.

Just to stir the controversy

No fish eye lens used

"Canon 6D camera, 14mm f/4 lens, ISO 1600, 3600-second exposure"

With fisheye lens

"Canon 70D camera, Samyang 8mm f/5.6 fisheye lens, ISO 400-1600"

 

[trunks2k]

Not sure what the above is supposed to demonstrate. The first image is taken from a mountain in Hong Kong, where you can see stars in the north and southern hemisphere, thus if you look north you see the stars "orbiting" around a pole and as you pan south, the "orbits" change to a straight line, then as you pan further south, the "orbits" converge to one around another pole. That's exactly what you should expect to see in a spherical earth. The regular lens gives you a smaller bit of the sky. Go to here http://neave.com/planetarium/ and set your location to Hong Kong, look east or west and then above the horizon. Then just change the minutes to make the stars move, you'll see stars from the north move into view from the left and move out of view from the left, and stars from the south coming/going from the right. It's a little subtle, but more obvious if you pick a point along the equator rather than Hong Kong.

The second image has the camera pointed at one pole, so the stars "orbit" around that pole, and it uses a fish eye lense to give a wider view of the sky and a more complete view of the stars' path. You'd get the same effect if you used a normal lens and pointed it straight at a pole, you just wouldn't be able to see as many stars (eta: as seen here:

(north pole) and here:

(south pole))

His Son--He paid the penalty for all--it's a done deal, all anyone has to do is accept it

I've never understood this. If you believe in the Trinity concept then three are ONE God -- ok, I can wrap my head around this even though it doesn't really make sense, I can suspend disbelief.

This God is at least maximally knowledgeable and powerful (to avoid the logical contradictions of being all-powerful) therefore this God would have KNOWN what torture felt like, would have KNOWN what 'dying' felt like, etc.

AND Jesus didn't actually die, and is still God -- what EXACTLY does this 'sacrifice' entail? Experiencing something you would have already known with God-level powers? I fail to see any sacrifice at all.

Furthermore, I categorically reject this supposed sacrifice -- the concept that another being must suffer for MY failures is actually repulsive to my ethic, where I have done wrong punish ME (or better, I should atone). If you think that some eternal torture is 'Justice' for finite crimes then I also find your ethic wanting. Which goes to the next problem...

Stepford Heaven. You have this Heaven where, supposedly, my mother (who was a Christian until her death - if not my mother then some other) will be:

Revelation 21:4 And God shall wipe away all tears from their eyes: and death shall be no more, nor mourning, nor crying, nor sorrow shall be any more, for the former things are passed away.

Which raises the specter of someone (say a parent) having a dearly loved one (such as a child, such as me) suffering eternal torment in Hell (or eternal separation, or non-existence -- depending on which Bible verses you choose to ignore) while they are WITHOUT mourning or sorrow or tears for their loved one.

This isn't the Mother I knew and loved, it is a heartless and twisted version - I would take the flawed Mother over this version.

Then we can talk about the failures of ordaining Slavery, commanding and committing Genocide, and commanding and committing Infanticide in the Bible...

A gyroscope need to be reset every 15 minutes. That are not even accurate for a 90 degree turn, much much less the curve of the globe at 8 inches per mile.

 

[lesliedellow]

I hate to tell you this, but an altimeter measures air pressure. It has nothing to do with a gyroscope.
