Default Andromeda Galaxy or US (What if)

Double-A WOW great information,on something that is 2 million LY away.
My "Spin is in theory" should show that a dense fast spinning object has
an influence over other objects at a distance. Much like two pendulum
bobs will line up their swings. Motion and gravity are equivalent,and I
use spin for attraction for both gravitational force and magnetic force.
Spinning in the same direction gives attraction. Spinning in the
opposite direction gives repulsion. This is an easy experiment when
using spinning tops.(that naturally is relative to each other.) TreBert



I still don't know the direction of Andromeda's rotation, nor the
orientation of its disk relative to the Milky Way. Pictures show
different orientations, and some of them are reverse image. If one
were to just look at Andromeda with one's own telescope, it should be
easy to see how it is oriented in the sky, and then compare that to the
northeast to southwest band of glow of the Milky Way. The direction
and orientation of the two galaxies' rotations would certainly make a
differenct to the outcome of a collision.

Did you know that the Milky Way is already colliding with a several of
smaller galaxies?

"Like other galaxies, the Milky Way is growing by absorbing small
satellite galaxies. It is currently merging with the Large and Small
Magellanic Clouds, a process that will be completed in about 100
million years. In 2003 a previously unknown galaxy was found to be
colliding with the Milky Way. Its distinctive red stars are slowly
being pulled into the Milky Way, and the dwarf will soon lose all its
structure. Called the Canis Major dwarf galaxy after the constellation
in which it lies, it is about 25,000 light years away from the solar
system and 42,000 light years from the center of the Milky Way. This is
closer than the Sagittarius dwarf galaxy, discovered in 1994, which is
also colliding with the Milky Way. Several other galaxies are also,
apparently, on a collision course with the Milky Way. The biggest and
most spectacular collision will be with the Andromeda Galaxy. In about
2 billion years, massive tidal gravitational effects will tear spiral
arms apart and start to shred the pinwheels from the outside in. The
result will be an elliptical rather than a spiral Milky Way." Double-A
