Are the Earth and Sun stationary?

Well, that's not consistent in all frames of reference, so that's probably not our answer.

LOL. That may end up on my office door.

Could Gravity be moving really, really fast to explain why the Earth appears to be orbiting in a plane around the center of our Sun?

Look, if you want to say that roads "move" infinitely fast between cities, that's up to you. The question is how fast the cars go. Assuming that gravitational fields "move" infinitely fast, how fast do gravitational waves (i.e., undulations in the field) move?

(HINT: Tom Van Flandern says that electromagnetic fields move infinitely fast, yet undulations in the field demonstrably move at the speed of light.)

Your office is obviously in a classy neighborhood. On my office door it says: "No Panhandlers!"

You're not following where I'm going with all of this. I'm not saying that roads move infinitely fast. I'm not even saying that road construction moves infinitely fast.

But road construction does move forward at some speed.

Likewise, a magnetic field moves forward at some speed as soon as you turn on the electrical power to the magnet.

And it's a reasonable bet that Gravity propagates its effects outward at some speed once you have assembled a mass.

The Einstein camp seems to hold that magnetic fields are going to propagate outwards at the same speed as do electromagnetic waves, likewise for Gravity.

Both the Einstein and Newton camps seem to hold that Gravity's field propagates faster than Gravity's waves, which seem to have been shown to accelerate at 9.8 m/s^2.

And the Newton camp further seems to hold that Gravity propagates at near infinite speed, rather than at the speed of Light claimed by the Einstein camp.

OK, so the Einstein and Newton camps appear to disagree on the propagation speed of Gravity's field (size, boundary, limits, effects, insert your redundant explanation here).

Fair enough. Let's observe a large system and see if we can identify whether Gravity has the same time delay as Light. Let's measure whether we see Gravity from the Sun that is 8.3 minutes old as we currently do for Light.

And this should be able to be measured by looking at where the planes of the orbits of our planets are centered, presuming that the Sun is not *absolutely* stationary.
