Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is ...

Two galaxies that are curiously lacking in dark matter — the most abundant matter in the Universe — might have formed when a collision between dwarf galaxies separated ordinary matter from its dark ...

The search for dark matter – an unknown and invisible substance thought to make up the vast majority of matter in the universe – is at a crossroads. Although it was proposed nearly 70 years ago and ...

The "missing baryons problem," the discrepancy between the predicted and observed amount of normal matter in the universe, has persisted for over two decades. Scientists have previously located only ...
