Dark Matter Core, Left Behind from Wreck Between Massive Clusters of Galaxies, Defies Explanation
Astronomers using data from NASA's Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision.
Studies of Abell 520 showed that dark matter's behavior may not be so simple. Using the original observations, astronomers found the system's core was rich in dark matter and hot gas, but contained no luminous galaxies, which normally would be seen in the same location as the dark matter. NASA's Chandra X-ray Observatory was used to detect the hot gas. Astronomers used the Canada-France-Hawaii Telescope and Subaru Telescope atop Mauna Kea to infer the location of dark matter by measuring the gravitationally lensed light from more distant background galaxies.
The team proposed numerous explanations for the findings, but each is unsettling for astronomers.
I think the words they should look towards are 'plasma' and 'electricity.'
Can anyone come up with an EU explanation of what the scientists are seeing? As a layman, my knowledge in these matters is a bit limited, even after reading the Essential Guide.
