Is Dark Matter A Hoax ???

According to a recent study, "dark matter" is really dark:

A new study published Thursday in Science suggests that dark matter might be able to zip through the universe without slowing or dragging because particles of it don't even interact with each other.

Based on what we can observe about the universe, galaxies should be tearing themselves apart. That's where so-called dark matter comes in: It's a term for the as-of-yet unobserved matter that must be bulking up cosmos, giving galaxies the gravity they need to spin at the rates they do without falling to pieces. But even though we haven't caught dark matter (so named because it doesn't interact with light the way normal matter does -- not absorbing or reflecting it -- though it does bend light with a weird lensing effect) in a straightforward observation, scientists can learn about it based on the effects it has on more typical, observable forms of matter.

In fact, it appears there is no direct evidence at all of its existence.

It is said to exist because no one understands how momentum appears to be distributed in galaxies. But is totally invisible and undetectable "dark matter" the only possible explanation for that momentum distribution? Of course not.

Time to come up with an explanation which does not involve invisible and undetectable matter - something like maybe the galaxies are created from the inside out instead of being formed by gravitational accretion.
