LUX-ZEPLIN (LZ):
As of today, the most sensitive dark matter detector experiment in the world is LUX-ZEPLIN (LZ) in South Dakota in the U.S.
- Many physicists strongly believe that the entire visible part of the universe forms only 5% of all matter in it.
- They believe the rest is made up of dark matter and dark energy.
- Dark matter is made up of particles that do not have a charge. So, these particles are “dark”, namely because they do not emit light, which is an electromagnetic phenomenon, and “matter” because they possess mass like normal matter and interact through gravity.
- There is strong indirect evidence for dark matter, and this evidence is reflected at various levels (or distance scales, as physicists would explain).
