" ... Graph showing the precession rate shift during an eclipse. ... "
" ... The Gaia data confirms that this warp is not static but changes its orientation over time, says the space agency. Astronomers call this phenomenon precession and it could be compared to the wobble of a spinning top as its axis rotates, says ESA. The fact that the warp itself is rotating much faster than previously thought indicates that they warp must be due to something external to the Milky Way itself. In other words, something more powerful – like a collision with another galaxy, says ESA. ... "
" ... The list of Einstein’s successes is long, from gravitational redshifts to the Lense-Thirring effect to the precession of black holes in binary orbits to gravitational time dilation and a whole lot more. Every test we’ve figured out to throw at General Relativity, from experiments here on Earth to observations within our Solar System to the arrival of signals from billions of light-years away, all point towards it being correct under every known circumstance. ...

" ... The main effect of this precession on temperature is seasonal, however, and has no long-term effect on an annual basis. Because the South Pole points towards the Sun close to the December solstice, orbital perihelion aligns with its summer and aphelion is close to its winter, resulting in colder winters and hotter summers compared to the Northern Hemisphere. This will change over time with a ~23,000 year period, but presents no long-term, overall temperature variations. ... "
