The advance of the orbit of Mercury is due to Mercury falling into the gravity well of the sun. Well that is normal way to look at it like the sun pulls Mercury around more or the path through the well the distance is shorter and Mercury advances. The other way (based on an alternate time dilation model) is that time is deformed and Mercury experiences more time in the orbit and so there is more time for the linear pull of the sun to deflect the orbit.

The big thing here is that Mercury as a planet would experience less linear gravity from the planet due to being in a greater time frame so things on the planet would be lighter in the stretched time frame of Mercury’s gravity. It would lead to greater tectonic movement and planetary heating from internal stress differences.

Significant for us in that if we are to likewise experience a movement through a gravity well brought about by super galaxy structure far greater than the Milky Way galaxy we could then see the Earth experience similar effects. Sure tidal waves, variation on the internal stresses on the planet, tectonic movements, earthquakes and so on. But the plus side is that linear gravity greatly reduces (not to zero) at this time which makes all things lighter while propulsion stays the same for a very brief interval of a few years.

How do you tell anyone that it may be the years around 2012 that a real window for interplanetary colonization opens in such a way that might not be experienced again for perhaps thousands of years. Imagine if we were not prepared and missed it.
