It's the main engine driving the whole evolution of the universe from the Big Bang to how we look out now and see the large scale structure we do.

And yet we don't know anything about how it interacts with normal matter.

It's sort of like a known unknown.

We know there is this treasure trove of new discoveries to be made.

And I just know that's where the next breakthrough will be.

But we're not there yet.

We need to explore all the different avenues

But it's not like we don't know it exists.

And that's what's, well, both frustrating, I suppose, but also intriguing.
