In the context of modern scientific research, consider the following statements about ‘IceCube’, a particle detector located at South Pole, which was recently in the news:1. It is the world’s largest neutrino detector, encompassing a cubic kilometer of ice.2. It is a powerful telescope to search for dark matter.3. It is buried deep in the ice.Which of the statements given above is/are correct?
✓ Correct answer: d) 1, 2 and 3
ExplanationThe IceCube Neutrino Observatory is the first of its kind, designed to explore the cosmos from deep within the ice at the South Pole.It is operated by the IceCube Collaboration, an international team of scientists conducting research in this field.By detecting high-energy cosmic neutrinos, IceCube enables the study of some of the universe’s most violent astrophysical events, including stellar explosions, gamma-ray bursts, and catastrophic interactions involving black holes and neutron stars.Statement 1 is correct: The IceCube Neutrino Observatory is the largest neutrino detector globally, occupying a cubic kilometer of ice at the South Pole.It detects high-energy neutrinos from cosmic sources like supernovae, black holes, and gamma-ray bursts.Statement 2 is correct: IceCube plays a critical role in the search for dark matter by detecting neutrinos produced when dark matter particles, such as WIMPs (Weakly Interacting Massive Particles), interact or annihilate.This makes it a vital tool in astrophysical and particle physics research.Statement 3 is correct: IceCube’s detectors a
