Previously, in another blog, I research hollow earth and determined that a gyroscope would easily detect the hole at the north pole. I've never applied the gyroscope to the flat earth however. Now, I will submit an idea for determining flat vs globe earth using a gyroscope. This can be done at the equator or, more easily, at 60 S Lat where less land is in the way or even around the circumference of Antarctica. It can even be performed on a flight across the Atlantic Ocean or anywhere in the northern hemisphere. For the purpose of this blog, however, I'll think about what it would be like to watch a gyroscope as we go around Antarctica.
If you start the gyroscope by orienting it as a circle in front of you, then tour the Antarctic shoreline around 75 degrees South Latitude, it will swing from left to right around a full circle-- if earth is flat. If Earth is a sphere, however, it will tilt from top to bottom and bottom to top again in addition to turning left to right.
Here's a pilot who calmly and rationally explains how, if earth were spherical, that his attitude indicator would have to indicate that.... except it doesn't. He never had to teach about correcting for earth's curvature.
Now here's a carousel. Consider riding a horse on a carousel while holding a powered gryoscope-- or just one wound up before the ride since it would last 3 minutes. Think of the carousel as a metaphor for riding around Antarctica. If the earth is flat, the gyroscope would merely rotate sideways. However, if the earth is a sphere, the gyroscope flywheel would have to flip at an angle in addition to rotate sideways.
This year, 2017, I was finally able to find videos of airplane gyros which can spin for hors-- deonstrating that the earth does not spin.

"the mandatory reference for all aircraft in flight is "pressure altitude". This varies at low level according to "QNH" - the promulgated lowest forecast pressure (corrected to sea level) in the region you are flying in, and above a "transition altitude" (which varies from place to place: can be a low as 3000 ft or as high as 12,000 ft) all aircraft fly at "flight levels", 100 foot increments based on a notional standardised sea level pressure of 101.32 hPa and a standard barometric altimeter.
ReplyDeleteGiven all these complications, the business of maintaining vertical position (according to the direction of flight) and avoiding lightning, turbulence, icing, fog, volcanic ash.....involves so much short-term tweaking of controls that nobody... notices that we are actually following the curvature of the earth.
It's interesting to travel in the back of a big plane like a 380. The autopilot maintains itself at 40,000 ft (actually FL400) within 1 foot, but in order to do so, the tailplane has to thrash up and down like a porpoise."
"I've just demonstrated it to a prospective pilot. The trick was "if the number on the altimeter increases, lower the nose. If it decreases, raise the nose. Try to keep it at 3,000 ft." And to nobody's surprise, we followed the curvature of the earth for 200 miles. Which is just as well as otherwise we would have landed an embarrassing 133 feet above the runway (curvature = 8 inches per mile - you can see it on a long runway!)."

In the quote... "I've just demonstrated it to a prospective pilot. The trick was "if the number on the altimeter increases, lower the nose. If it decreases, raise the nose. Try to keep it at 3,000 ft." And to nobody's surprise, we followed the curvature of the earth for 200 miles.-- it's possible that the altimeter neither increased nor decreased-- and the plane stayed at 3000 ft. It SHOULD have been surprising if the number on the altimeter INCREASED since on a curved earth, the pilot would be continually flying HIGHER relative to the ground, into THINNER air, and thus have to CONTINUALLY compensate by LOWERING the nose.
DeleteThe pilot in the video above says there are no such corrections continually made -- even when flying by "pressure altitude". So, this is inconclusive.
The idea that the "business of maintaining position and avoiding fog, ash, lightning" with "so much tweaking" that "nobody notices they're flying curvature" is ridiculous in my opinion.
Ok, please correct me if I'm wrong, in regards to the last video about the gyroscope not moving...
ReplyDeleteThe gyroscope would move if you spun it relative to earth, right?
But if the gyroscope is set on a table, if the earth is spinning, so is the table, and so is the gyroscope, and there is no relative difference between the rate of spin, between the earth, table, and gyroscope. That's why nothing registers on the gyroscope.
The gyroscope would move if you spun it relative to earth, right?-- Right but we're not testing that aspect. We're testing the motion of the gyroscope relative to the universe-reference-frame of, for arguments sake, the stars.... and the motion of the earth as it rotates, relative to the stars. The earth spins every 24 hours relative to the background of those stars as the frame of reference while the gyroscope maintains it's position relative to the stars. In 6 hours, we should see at least a quarter turn, 6 being 1/4 of a 24 hour day.
DeleteHey speaking of gyroscopes, did you see that movie Contact with Jodie Foster?
ReplyDeleteThey built a giant structure that looked like a gyroscope.
The super miraculous gyroscope sent her through a... uh...wormhole.
She floated gently down to land apparently on the coast of an ocean.
The waves on the ocean were going away from the land.
She met her dad who had died.
Waves, there's another universally observed phenomenon.
Since they drift toward the shore, it suggests a push from above the top of the world (the crown) yeah?
If they were to drift away from the shore it would suggest a pull on the bottom of the world (the pavillion) from the top of the world (the crown).
If the bottom of the world is hollow, and the top of the world is filled, would the top pull on the bottom, by the centrifugal spin of a round heart and arrow diamond shape?
You might be onto something there-- but a diagram would help.
