Apparently dark matter should clump.
The Milky Way's satellites seem to be arranged in an implausibly thin plane piercing through the galaxy and, oddly, they are also circling in a coherent and long-lived disk.
The "plane of satellites".
There is no known physical mechanism that would make satellites planes. Instead, it was thought that satellite galaxies should be arranged in a roughly round configuration tracing the dark matter.
The fact that the arrangement of satellites could not be explained led researchers to think that the cold dark matter theory of galaxy formation might be wrong.
Who knew there was doubt, that dark matter should clump !?
But now computer models to the rescue.
However, this latest research saw astronomers use new data from the European Space Agency's Gaia space observatory.
These data allowed scientists to project the orbits of the satellite galaxies into the past and future and see the plane form and dissolve in a few hundred million years—a mere blink of an eye in cosmic time.
they found several virtual Milky Ways which boast a plane of satellite galaxies very similar to the one seen through telescopes.
Study co-author Professor Carlos Frenk, Ogden Professor of Fundamental Physics in the Institute for Computational Cosmology, at Durham University, U.K., said, "The strange alignment of the Milky Way's satellite galaxies in the sky had perplexed astronomers for decades, so much so that it was deemed to pose a profound challenge to cosmological orthodoxy.
"But thanks to the amazing data from the Gaia satellite and the laws of physics, we now know that the plane is just a chance alignment, a matter of being in the right place at the right time, just as the constellations of stars in the sky.
Random chance to the rescue.
I wonder if they will risk looking for other "plane of satellites" around other galaxies ?
The galaxies are electric; as Robertus Maximus says !
