The Big Bang created equal amounts of matter and antimatter. So, why is there so much more matter than antimatter in the Universe? Irfu is participating in the preparation of Hyper-Kamiokande, a ...

Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive ...

Dark matter is claimed to make up over 80% of all matter in the universe, but scientists have never seen it. We only assume it exists because, without it, the behavior of stars, planets and galaxies ...

In their search for dark matter, scientists from the XENON Collaboration are using one of the world's most sensitive dark matter detectors, XENONnT at the Gran Sasso Laboratory of the National ...

Physicists are preparing for the next generation of dark-matter experiments. Imagine all the matter in the universe is a set of billiard balls on a pool table, each awaiting the cue ball’s strike. If ...
