Dark matter darker and weirder?

So they say:

Dark matter’s presence is known only by its interactions with normal matter through gravity. It does not, however, interact via the electromagnetic force, which is why we cannot directly see it — it does not emit, scatter or reflect light — it is more “invisible” than “dark.”

In this new research, Harvey and his team realized just how invisible this stuff is, even to itself.

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. More.

    Just like the way the presence of a designing intelligence is known only by it’s interaction with normal matter that produces information, semiotic and cybernetic systems, natural laws with simple mathematical relationships and finely-tuned mathematical constants.

    The difference is that scientists are making every attempt to test their hypotheses through independent means, to determine the posited dark matter’s specific properties, and to directly detect dark matter. Results of these investigations will inevitably result in the modification or discarding of current hypotheses, and the generation of new ones.

    But not with evolution or global warming (oops, climate change), because we all know that “the science is settled.”

    There are entire scientific journals of studies concerning evolution, including Journal of Evolutionary Biology, Molecular Biology and Evolution, and Evolution; plus specialized journals, such as Journal of Human Evolution and Insect Systematics & Evolution. Other major journals also publish research into evolution, including Nature and Science.
