Dark Matter Is Even More of a Mystery Than Expected

schwit1 writes: Using the Hubble and Chandra space telescopes astronomers have discovered that dark matter is not only invisible to direct observation, it is invisible to itself! Quoting: "As two galactic clusters collide, the stars, gas and dark matter interact in different ways. The clouds of gas suffer drag, slow down and often stop, whereas the stars zip past one another, unless they collide — which is rare. On studying what happens to dark matter during these collisions, the researchers realized that, like stars, the colliding clouds of dark matter have little effect on one another. Thought to be spread evenly throughout each cluster, it seems logical to assume that the clouds of dark matter would have a strong interaction — much like the colliding clouds of gas as the colliding dark matter particles should come into very close proximity. But rather than creating drag, the dark matter clouds slide through one another seamlessly." The data here is on the very edge of reality, built on too many assumptions. We know that something undetected as yet is influencing the motions of galaxies, but what exactly it is remains completely unknown. These results only make the mystery more mysterious.

Electric Universe

The answer to what they're missing: Electric charge and currents.

The electric universe folks explain that galactic rotation rates do not require dark matter to make sense. The electric current through the galaxy adds forces on the charged stars and gasses that adds up to explain the observed motions. This article sheds more light on the problems with the dark matter theories. It's time to more strongly consider the possibility that dark matter isn't the answer.
