Why can't gyroscopes detect earth curvature when planes fly 1000's of miles?

The sun circles between the Tropics, 23.5 degrees North of the equator in the Tropic of Cancer and 23.5 degrees South of the equator in the Tropic of Capricorn. All the celestial bodies are energy for earth and rotate above us, earth is level and stationary. This can be observed by the 2d counterclockwise, clockwise and counterclockwise change in orientation of sun spots on it's diurnal circuit. That is impossible looking at the sun 93 million miles away on a globe rotating West to East.

Chandler wobble is caused by the moon's monthly nodal (Draconic) cycle interacting non-linearly with the annual cycle. The cycle is 365.25/13.606 modula 26 = 0.845/yr which is 433 days, the exact period of the Chandler wobble. This is an example of a forced response, not related to the inertial moment of the Earth. However, the frequency response of the natural resonance does help as it lies within the Q-factor bandwidth.

Даже ребенку понятно, что Луна была создана или пригнана доевними, Богами как хотите их называйте, для сьабилизации вращения земной оси! Видимо это произошло после некой космической катастрофы нарушившей порядок в солнечной системе, сместившей и ось земного вращения и наклон! А так же вращение вокруг своей оси Венеры, вращающейся в отличие от др.планет по часовой стрелке, а Плутон вообще вращается лежа на боку! Да, древние мудро пристегнули луну к земле, одной стороной создав некий баланс регулирующий массы океанов в более стабильном состоянии. И тут огромная загадка кто создал луну и когда!

On page 1:10 and up. Note the spin rate and precession rate ratio. Do we think this represents the same ratio with earth’s precession? Earth precession is 1-degree every 72 years. One precession cycle takes 360x72x365 days or 9,460,800 earth spin cycles in each precession. Congratulations to this demonstration. In this video we saw a precession, not sure this represents earth’s precession.
@apmggroup-unibonn3544
@apmggroup-unibonn3544 Год назад
The purpose of the gyro in this video is to illustrate the difference between forced and free precession. It is not intended to be an accurate model of the Earth. The luni solar precession does in fact have a period of about 26,000 years (1 degree every 72 years). It is caused by the Sun and Moon, acting on the equatorial bulge. So it is a forced precession. But at 1:10 the gyro is used to illustrate free precession, not forced precession.

Thank you for your comment. You are right, the direction of the arrow does not conform to the conventions. But the only purpose of the arrow is to show that the rotating disc maintains its orientation. This statement is not affected by this.

Yes, I even had to watch this video 3 times in slow motion to confirm ¯\_(:|)_/¯ Also it is probably ambiguous when people say they "apply torque". I guess they apply force (or impulse) on the gimbal, which in its turn MAY create torque. In this video the flywheel can rotate on 3 axes, but there are gyros with only two perpendicular axes and thus one orthogonal axis (and torque direction) is inaccessible.

A cheap one would be alot of fun. Don't know if it would affect a static gravitometer, but there is a claim that if alignments are correct an eclipse can cause a pendulum to reverse it's motion.....I wonder if that thing would detect a signal? Check the future eclipse charts for your region....who knows?
