Astronomers may have found the long-missing half of the universe's regular matter—and it appears to have been right under our noses all this time. Models of how the universe has evolved since the Big ...

Gazing up at the stars at night, it’s easy to imagine that space goes on forever. But cosmologists know that the universe actually has limits. First, their best models indicate that space and time had ...
