If not in visible stars and galaxies, the most likely hiding place for the matter is in the dark space between galaxies.

Half of the universe's ordinary matter was missing — until now. Astronomers have used mysterious but powerful explosions of energy called fast radio bursts (FRBs) to detect the universe's missing ...

Ever lost your phone and your spouse said, “Have you looked in the couch?” and of course you looked in the couch, it was the first place you looked, and it wasn’t there, and the spouse looks between ...
