About four decades ago, astronomers realized that our galaxy, the Milky Way, moved through space at a much faster speed than expected.At 2.2 million kilometers per hour , the speed of the Milky Way through the Cosmos is 2,500 times faster than a cruise passenger plane and 55 times faster than Earth's escape velocity.But this movement comes from a mysterious and great attractor.

What is the Great Attractor that is pulling our galaxy?

The net movement can arise from nearby clusters in the distribution of matter , as a massive cluster of galaxies.The additional gravitational attraction of this group of galaxies can be delayed, and even reversed, according to the expansion of the Universe in its vicinity.

But there seems to be no such group in the direction of the Milky Way movement .There is an excess of galaxies in the general neighborhood, and an excess of visible radiation in X-ray telescopes.But nothing that Somehow it seems big enough to explain these velocity results.

So, are we moving because of an excess of pure dark matter density? Or is it the current theory about the origin of mass and the wrong movement? The astronomer Alan Dressler of the Carnegie Institution, uses the first theory, to explain the concentration of missing matter, with the so-called «Great Attractor».

But another explanation may be in the fact that the inferred direction of the missing matter is not too far from the direction of the Carbon Sack nebula , which lies deep within our own Milky Way.
