Yeah I will do a Dark Matter thread soon

According to the OP, our galaxy is the Sagittarius galaxy, which on collision with the Milky Way has left us ensnared in one of the spirals of it.
So we're the Sagittariuns.. Invading the larger and cannibal milky way galaxy!
Nicely put The irony is that I really am a sagittarian
Studies of the Sun’s motion relative to the plane of the Milky Way (using the stars, globular clusters, other galaxies, and many other sources) make it a rock-solid certainty that the Sun’s orbit is in fact in the plane of the Milky Way. It’s not plunging through the disk at a high angle at all.

Quite a lot of information here and I am curious about this I must admit. Since the information given is very credible I wonder if the fact that our solar system lies near one of the stretched out arms of the SEG, could some of our past history regarding Nibiru hold some truth?
The first all-sky maps from the Interstellar Boundary Explorer (IBEX) satellite (McComas et al. 2009a) revealed that the most prominent feature of the sky seen in the 0.2-6 keV Energetic Neutral Atom (ENA) emission is a ‘ribbon’ of enhanced ENA flux (McComas et al., 2009b) forming an almost complete circle in the sky of about 140° diameter and centered on ecliptic/galactic coordinates (λ, β)/(l,b) = (221°, 39°)/(33°,55°)

This theory was debunked many years ago.
Is this what ATS has been reduced to? Doesn't anyone bother to do a little bit of research?
This story first broke way back in 2003 and was promptly dismissed:
Two collisions with a dwarf galaxy over the last nearly 2 billion years may have been the cause of the Milky Way's spiral arm structure, scientists say.
The new findings hint that impacts with even relatively small galaxies have played an important role in shaping galactic structure throughout the universe, researchers said.
In trying to explain the shape of our own galaxy, the Milky Way, with its prominent spiral arms rooted in a central bar, scientists have traditionally dismissed the influence of outside forces, even though astronomers have seen shape-changing mergers of other galaxies.
For their study, scientists focused on the nearby Sagittarius dwarf galaxy, much of which had been ripped apart by the gravitational pull of the Milky Way, leaving debris that forms a huge but very faint stream of stars around our galaxy. Altogether, this dwarf galaxy might have once been far more substantial, maybe 100 times more massive
A dwarf galaxy that is too dim to see but is suspected to orbit our own Milky Way may soon be revealed using a new mathematical technique that analyzes the ripples of gas in spiral galaxies.
The new method was developed by Sukanya Chakrabarti, a post-doctoral fellow and theoretical astronomer at the University of California, Berkeley. She thinks it can be used to detect the hypothetical so-called "Galaxy X" near the Milky Way.
The model may also have applications for detecting mysterious and as-yet inexplicable dark matter, which is thought to make up the bulk of the universe.
"My hope is that this method can serve as a probe of mass distribution and of dark matter in galaxies, in the way that gravitational lensing today has become a probe for distant galaxies," Chakrabarti said in a statement.

Makes for a good story unfortunately is is not sound science and easily dispelled as fiction.
The SagDEG wasn't discovered until 1994, both because it is very dim, and because it was obscured by the central part of our galaxy. Though this galaxy is quite big (about 10,000 light years across), it will likely be disrupted by the tidal forces from the Milky Way Galaxy.
- it is so close to us, that some of the SagDEG's stars are actually in the outermost regions of the Milky Way!
The Canis Major Dwarf Galaxy is only 25,000 light years from the Sun, and 42,000 light years from the Galactic center. It too, is well-hidden by the dust in the plane of the Milky Way - which is why it wasn't discovered until recently.
This galaxy is also being pulled apart by the Milky Way's gravity - as it orbits the Milky Way, it is leaving a long filament of stars, gas, and dust in its wake. This 200,000 light year-long filament is known as the Monoceros Ring, and actually wraps three times around our galaxy! The Canis Major Dwarf galaxy was discovered in the course of the investigation of this Ring, which was first discovered in 2002. At left is an illustration of the Milky Way, the Canis Major Dwarf, and the stream of material coming from the Galaxy.
