Once a particle of matter, always a particle of matter. Or not. Thanks to a quirk of quantum physics, four known particles made up of two different quarks—such as the electrically neutral D meson composed of a charm quark ...

In the first moments after the Big Bang, the universe expanded many billions of times faster than today. Such rapid expansion is likely due to a primordial force field acting with a new particle, the inflaton. From the latest ...
