Dark matter mystery: Why there is no light yet after decades of search

July 08, 2025 1:59 pm

Despite decades of searching, scientists still haven’t found the elusive substance that holds galaxies together: dark matter. Making up roughly 27% of the universe, it exerts gravity but doesn’t emit or absorb light.

Knowledge nugget, neutrinos, ghost particles, Cubic Kilometre Neutrino Telescope

Knowledge nugget of the day: Ghost particles - Neutrinos

January 10, 2025 11:55 am

The Cubic Kilometre Neutrino Telescope or KM3NeT is deployed under the Mediterranean Sea to detect high-energy neutrinos, also known as ghost particles. But why are neutrinos called ghost particles? Also, in Beyond the Nugget, learn about dark matter.
