Is the precession of the equinoxes a theory?

Answer 1

If you could verify that the vernal equinox location, by about March 21, is displaced every year forward along the equator by about 1600 meters 9 nearly a mile), it is the evidence.

As of right now, I believe the longitude for the equinox intersection of the equator with the Earth's orbital plane is close to the longitudes of New Papua Guinea Island, north of Australia, and that at vernal or autumnal equinox instant and location on the equator, the noon Sun will be directly overhead.

I have determined this displacement in the response for confirmation from

#((2pi)#/.(precession period))(Equatorial radius of the Earth)

641 km/year = (6.2832/25800 years)(6738 km).

No, the precession of the equinoxes is not a theory. It is a phenomenon caused by the gradual shift in the orientation of Earth's rotational axis over time.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
