Dark Matter potentially solved: "doesn't exist"

Here's a link to the reddit thread since the source is down from too much traffic. Physicists suggest we might have just found dark matter while detecting gravitational waves. : science

Ooooooooooooooooooooooooooooooooooohhhhhhhhh

On one hand it'd be nice to have the dark matter mystery solved, but on the other hand it's much less cool than if dark matter particles existed.

Yeah definitely is. Black holes are awesome though.

I figured this was the direction we were heading.

When we talk about Dark Matter, are we talking about all those planets from suns that released all their hydrogen so we can't see them anymore?  Or are we talking about Dark Energy?

Neither.

Dark matter is a moniker for the unaccounted mass found throughout the universe, primarily with galaxies having way more mass than visible and that mass clumping in a halo far away from where stars are. 95% of the milky way's mass comes from dark matter.

The most popular theory for dark matter is that it's an undiscovered type of particle that doesn't interact with the electromagnetic force. The recent Ligo black hole observations lend credit to the theory it's instead black holes.

One could kind of argue the first part could be a source of that.  
But the second suggestion is nonsensical.  Dark Energy and Dark Matter are completely different, they can almost be considered opposites of each other in some respects.

I think they should stop calling every unknown in the universe as "Dark".

Dark Planet.

I still wonder where black holes lead to..

Says the guy whose username starts with dark.

Death?

Would be a fun way to go, ignoring all the pain and suffering of course.

Always gotta look on the bright side of life

lol what Legend said.  

If we think of Dark Matter being the reason why gravity seems to be stronger than it should be, Dark Energy could be thought of as the reason why gravity seems to be weaker than it should be.  

Basically the reason why Dark Energy is being considered a possibility is that we expect gravity to be slowing down how fast the expansion of the universe is.  What we observe is that the expansion isn't slowing down at all, it's not even staying constant.  It's actually increasing.  The hypothesis suggest that Dark Energy is the reason for the acceleration, almost an "anti-gravity".
