Einstein predicts two types of time dilation, both of which have been tested and confirmed. One is…
Most of Earth’s continents are located in the northern hemisphere. This may be mere coincidence, or it may have an explanation similar to that of the lunar south pole anomaly.
If there is a current going through the solar system from south to north, then there is a predominance of massive particles striking the south pole relative to the north pole.
This has the effect of carving out deeper craters on the south pole of our moon. Similarly, it will have the effect of softening up the crust on Earth’s south pole more than the north pole. This would then lead to more expansion south of the equator than north of it.

From measurements, we know that very few particles coming in through the polar auroras actually hit the surface of our planet. Most particles return to space, so the difference in crustal massaging going on at the two poles is likely to be subtle.
However, even small differences can yield profoundly different outcomes over time.
