Yes, that is true, but it doesn't change over time. So that is not relevant.

Nonsense. It is regukarly tilted up and down by the moon's pull. It seems like yoju have to study gyroscopes more.

So which equatorial bulges are you talking about? The one along the equator caused by the Earth's spin, or the two caused by the Moon that aren't neccessarily on the equator, or the two caused by the Sun that aren't neccessarily on the equator?

DavidMcC wrote:I was talking about the earth's oceans. They spin with the earth, but the plane of their spin can be tipped by the moon. It's a gyroscopic effect.

Speaking of misconceptions.
