ONE snowy day last year, I trekked out of Vienna, Austria, winding my way to one of the city’s graveyards to visit the final resting place of a giant of 19th-century physics. Ludwig Boltzmann’s ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Suspect in Minneapolis school shooting identified Donald Trump Nobel Peace Prize comment ...
