“Your friendly reminder that dark matter comprises 25 percent of the mass energy budget of the cosmos, while dark energy comprise 70 percent, and the normal matter that you and I are made of is just a wee 5 percent. And it’s all connected by a cosmic web of filamentary bridges that stretch across millions of lightyears. Carry on.”
