So SpaceX got more rocket back than they planned for, I think?

No. They added recovery systems to the launch fairing. Those systems were experimental, but successfully salvaged half of the launch fairing.

For a second I was confused and thought you were saying they got more rocket back than they launched... in my defense, I'm on some pretty potent cough medicine right now

"After today's space launch, onlookers were stunned when Elon Musk announced they had recovered not one, but *two* first stages from the mission. "It was just hovering there over the ocean next to the drone ship, so it was easy enough to pick up," the eccentric billionaire was quoted as saying. Analysis of the recovered craft showed it to be made of a material unknown to science, but otherwise built to the same specifications as the first. "Just goes to show you," Musk continued, "that we are on the right track for revolutionizing the cost of spaceflight with 100% reuseability.""

It turns out that just running more detailed simulations of the equations for the standard model of cosmic evolution they were able to remove more of the simplifying assumptions, and the pre-dark energy theory actually accounts for much more of the variation than was previously claimed.

Wasn't dark matter/energy just a term for "Our model predicts that there must be SOMETHING but we can't SEE it so it's gotta be DARK"?

Yes, if you want to make it sound stupid.

Also, the two concepts are unrelated.

It doesn't sound stupid, just a reference to an unknown/unobserved but predicted phenomenon.

Yes I realize they're unrelated, aside from the name

Dark Matter is the opposite, it is an observed phenomenon (galactic rotation curves) which was later linked to another observation (light passing through galaxy clusters is lensed in a manner which indicates that there is far more mass present than the visible matter can account for) and then we determined that it can't just be dim ordinary matter (because we saw two clusters which passed through each other and the distribution of stars, intercluster gas, and mass is all fucked up but clearly indicates that there is a lot of shit we can't see directly there) so we're now in the phase of "what is this stuff, what properties does it have, can we shake the standard model until it falls out?" science regarding dark matter.

Also another story on that site was about giant sloths digging tunnels?

Sounds like a real pain...

There's a radio (semi-comedic, in approach, but studious in scope) quiz programme called "The 3rd Degree" that has just been re-(re-re-)repeated on BBC Radio 7Again (for I'd heard this episode multiple times before) I was annoyed when a provided answer "Dark Energy" was replied to by the questionmaster (who read English at Cambridge, where he also got his Footlights introduction) with "Correct, Dark Matter", or somesuch.

Still, I'm betting I'd do no better with ambiguous mispronunciations of something Chaucerian...

Technically still science: an official FEMA estimate on effects of full-scale nuclear war on USA, complete with geographical maps of nuclear explosions. Some places get, like, ultranuked, like New York or, for some reason, North Dakota.
