Same. My gut immediately told me it was the left, then I figured this article would go on to illustrate some sort of illusion and the truth would be that they were equal or the right had more. So yeah, wrong and right.
Indeed - replace the fake finger quotes with real quotes, and it still reads as intended:
In fifth grade we had two teachers and one of them would routinely be "sick", because her "medicine" sometimes had "side effects". That's sort of what is going on while I am out this weekend.
You're not wrong, but the difference is a matter of degree. Whether we say "we don't know" or "we know it's this thing that we don't understand" isn't all that different. You only run into trouble when people take the "we don't know" side too far and say things like "dark energy is made up" or "dark energy is the new religion!" as a trendy way of making themselves feel like they know more than the scientists. Dark energy is "made up" the same way anti matter is "made up" - it's a proposed solution to problems in physics. Since we "made it up", various observations and calculations have shown that we are on the right track.
It's not that big of news because it doesn't really tell us anything new - we already *know* that dark energy and dark matter are out there, we just don't know what they *are*. And, as of today, we still don't.
