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 ab0ut it based on the effects it has on more typical, observable forms of matter.

"If you bang your head against the wall, the electrostatic force between the molecules in your head and the ones in the wall cause a collision. This is what dark matter doesn't seem to feel," ...
Tom Kitching poo-poo'ed the "darkness" of dark matter:
Sometimes I think dark matter is a terrible name. It was originally coined because the phenomenon does not emit or absorb light. But light is everywhere in the dark matter we have observed, passing within it and around it. Indeed, the lensing effect that we employed in our study uses the light from distant galaxies that has passed through dark matter.
So perhaps "transparent matter" or "clear matter" are better names. My favourite alternative is "materia incognita" (the unknown material). Maps used to be labelled "terra incognita" in areas that were unknown, and in a similar way we could be explicit about the unknown nature of this phenomenon.

I read somewhere...that Elon Musk claims that he will be using dark matter to fuel his next generation Teslas
Or better yet "matter that doesn't exist".
So either the universe is full of dark matter that no one can detect or their theories are a load of crap.
That’s racciss!
Science B raciss.....
Coming up shortly....crap farms!
Harf, Harf, Harf....

Those cupcakes, OMG. That baker must be a weird dude.
Im surprised obie hasnt formed a task force on this issue..yet
My dark matter is more exotic than your dark matter.
In a related story, Macy's is having a clearance sale of "Dark Matter" in their Bargain Basement, right next to the rack marked "The Emperor's New Clothes".
The home of the Les Folies Bergère. What can I say?

Well, when you put it that way.....
I’m guessing that bakery would have no problem at all serving up an appropriately disgusting “gay” wedding cake.
It doesn’t exist — it just bends light.
