Why Nobel physicist Francis Halzen built a giant ice cube to catch 'ghost particles'

Prof Francis Halzen has been awarded the prestigious Nobel Prize in Physics, recognizing his groundbreaking work in neutrino detection. His pioneering efforts led to the establishment of the IceCube observatory in Antarctica, dedicated to capturing elusive neutrinos generated by cosmic phenomena. In 2013, the observatory achieved a historic milestone by detecting the first extraterrestrial neutrinos, paving the way for new insights in neutrino astronomy and our understanding of the universe.
