If my data are correct this subject matter is quite important. These are personal opinions.

What I am discussing here is basic physics in terms which are about as simple as I can make them. At some point most of the people who have a reasonably good background in science should be saying, “Now I understand what he is talking about.”

VELOCITY AND ACCELERATION IN 3 DIMENSIONS

In our physical universe we see things largely as they exist in 3 dimensions. Z - up and down, X - left and right, and Y - directly toward us or away from us (backward and forward).

An object moving in space has a velocity component in all 3 of those dimensions. It may be mostly moving from left to right in the X dimension. But is will also be moving at least a little in the Y and Z dimensions.

If the object is speeding up or slowing down we say that it has positive or negative acceleration in one or more of those dimensions or directions. And if the rate at which it is speeding up or slowing down is increasing or decreasing we can refer to that as changes in its acceleration rate, or the “Impulse” as the person running that Grandunification Web site proposes.

THE VELOCITY AND ACCELERATION OF THE EARTH IN SPACE

Picture things in the following hypothetical picture:

All objects are fixed in space. Nothing is moving except the Earth around the sun. And there is no moon.

As the Earth circles the sun it has a certain velocity in 2 of those 3 dimensions. And it is constantly accelerating in one direction or the other in those 2 dimensions. That is what happens when an object travels in a circle.

Without too much trouble you can calculate what the changes are in the Earth’s velocity at any time, its acceleration, and it rate of change in acceleration or Impulse as it travels around the sun.

Now add the moon to the picture.

Each month the Earth and moon move in a circle around a point which represents their shared center of mass. That point is actually a ways down inside the Earth rather than somewhere out in space. To people living on the surface it appears that the moon is simply circling the Earth. But technically speaking that is not the case.

Since the Earth and moon are traveling in that circle each month around their shared center of mass they both should have velocity, acceleration, and Impulse components in 2 of those 3 dimensions or directions. However, the orbital plane of the Earth - moon system is not an exact match (parallel) with the orbital plane of the Earth – sun system. If you looked at the Earth – sun orbital plane as a piece of flat paper, the moon at different time in its orbit around the Earth would move above the paper and at other times below the paper. And the Earth would do that as well, but to a lesser extent because it is heavier.

What that means is that both the Earth and the moon are now moving in all 3 of those dimensions, up and down, left and right, and forward and backward. As a consequence they both have velocities, accelerations, and changes in accelerations or Impulse values in all 3 directions or dimensions. All of those values can be easily calculated for any point in time.

Because of the complexity of the orbits of both the Earth and moon as they circle their shared center of mass and the sun there are times when the acceleration of the Earth in space changes abruptly. You can see a plot of those changes in its acceleration or Impulse values versus time at that Grandunification Web site. And on that plot there are the times when quite a few earthquakes occurred.

Any volunteers on that?
