Matter

​A new phase of matter, called a time crystal, has been created for the first time. In a regular crystal, the atoms are arranged in a pattern that repeats in space, but in a time crystal, that pattern repeats through time. The creation of time crystals marks a new class of non-equilibrium phases.

An unusual state of matter, first theorized almost 50 years ago, has been created in experiments for the first time. Say hello to the supersolid, a state where atoms simultaneously exhibit a crystalline structure but still flow like a frictionless fluid.

By trapping photons inside a tiny gold cavity, scientists have created a hybrid state of light and matter. This could allow them to develop tiny on-chip lasers or tweak the chemical bonds of single molecules.

New research reveals that if the pressure is really extreme, like double that found at the center of the Earth, the innermost electrons of an atom change their behavior. The discovery opens up new realms for research into states of matter and challenges accepted notions about electrons.

Astrophysicists from the University of Waterloo have compiled the most comprehensive 3D map of our cosmic surroundings to date. The map describes how ordinary matter is distributed in space up to a distance of about a billion light-years away from us.

Physicists working at the Blackett Physics Laboratory in Imperial College London have designed an experiment to validate one of the most tantalizing hypotheses in quantum electrodynamics: the theory that matter could be created using nothing more than pure light.

A study of 5.02 TeV proton-lead collisions at the Large Hadron Collider suggest that a new form of matter is being created.

Scientists have recreated conditions similar to those at the center of a star, using the world's most powerful X-ray laser.

The chi b(3P) is the first new particle that has been clearly observed using the Large Hadron Collider.

Contrary to claims from some scientists that the Large Hadron Collider (LHC) was being sabotaged from the future to save the world, it is now back up and running.

Roadrunner, the world’s fastest supercomputer, is being used to model one of the largest simulations of the distribution of matter in the universe to provide a better understanding of dark energy and dark matter.

The eROSITA X-ray telescope will search for black holes and dark matter, and may help explain why the expansion of the universe is accelerating instead of slowing down.
