Gyro Showing Precession

The wobbling of Earth's axis of spin is mostly due to the sun acting on the irregular distribution of mass associated with the bulge of Earth's equatorial region. Nutation, an extra wobble overlaid on the precession, is largely due to the moon. Precession has an effect on climate because of how the earth's North Pole points toward the sun when closer to it during part of the precession cycle of approximately 26000 years.

So why was this recommended for me?

@therealtreeguy65 That must have been because of the tags, perhaps because you seemed to like things with those keywords.

wow, I didn't really that... before I seen this video, I was like, where have I seen toys with precession...

[andrewburbidge]

@AnimeBelover It's a fascinating effect because when we tilt a gyro there is no obvious reason for any resistance. After all, it's not attached to anything solidly. But it exists as part of the 'fabric of space.' When it is twisted, then, there must be some reaction in that 'fabric' to resist the force applied. And what is mass? There is resistance to applied forces there - that is how 'mass' is defined. Is it not the same kind of change occurring? It is. Compressions among the cloves change.

Precession cycle is roughly 26,000 years.

The fixed stars appear to "fall back" 1 degree in 72 years.

This drives climate change, just as the tilt of the axis gives us winter and summer.

Lake Vostok and Epica ice core studies show carbon dioxide levels rise because of the Precession (for about 21,000 years) and then drop again as the earth cools.

@AcePilot101 While some stars rise with precession the ones on the opposite side of the sky fall. Do you happen to know if the constellation, Orion, is rising or falling at the moment? I think it is rising but I'm not sure.

@izus2002 @heyeriica see my movies, i have solved coral casle. and precession.. have you?he was 41 years off.

we are in aquarius now

[izus2002]

nice...

[coszcatl]

that was AMAZING omfg!
