Huge Lenses To Observe Dark Energy

Iddo Genuth writes "UK astronomers, as a part of the Dark Energy Survey collaboration, have reached a milestone in the construction of one of the largest ever cameras to detect dark energy by completing the shipment of the glass required for the five special lenses. Each step in the process of completing this sophisticated camera brings scientists closer to detecting the invisible matter that cosmologists estimate makes up around 75% of our universe."

dark energy?

They're making it sound like dark energy is visible light. If it's "dark" that means it's undetectable by normal means like giant lenses for instance. How could you just see dark energy? Isn't it more like something you'd detect with sensors, not a giant lense? But no, straight out of the article, they're gonna use it to for "detecting the invisible matter" because it has "advanced optics." Btw they said MATTER, not energy so apparently that's what they're actually looking for. Well that would officially make it dim matter, wouldn't it? Like I always thought, dark matter is just matter without a whole lot of light shining on it cuz it's in between galaxies and stuff.
