Perspective

Dark matter is a kind of cosmic spackle that fills all the gaps in the universe. Nobody's seen it (it's dark), but it's the best way to explain the discrepancy between how much the whole universe seems to weigh and how much all the visible things weigh when they're added up. Less than 5 percent of the universe is actual normal stuff like you and me and the galaxies. Dark matter is 23 percent, and the entire rest of everything, 73 percent, is something called dark energy. What I'm saying is, cut yourself a great big piece of king cake.
