One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key ...

For a long time, astronomers have noticed that stars rotate too quickly at the edges of galaxies, as if a hidden mass were preventing them from escaping. This observation raises a fundamental question ...

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...
