What On Earth Is Dark Matter?

Scientists are almost completely certain that 85 percent of the matter in the universe is something nobody has ever detected. So how does anyone know it's there?We get into the astronomer who noticed something was wrong back in 1933 and got ignored for thirty years, and the woman who proved him right by doing nothing more complicated than watching how fast stars move. You'll hear why galaxies should be flying apart but aren't, what scientists have buried a mile underground trying to catch, and why after ninety years of looking, nobody has found a single piece of the stuff.Dark matter is drifting through your living room right now, and that is the part we are most sure about.────────────────Enjoying the show?
